Race Fluids and Lubricants: Science Friction

Lubrication companies are expanding the envelope to develop specialized products for targeted applications, all while helping release untapped horsepower.

 

Rules can hamstring engine builders who want to make more power. Sanctioning bodies limit airflow, cam specs, compression ratio, and more in an effort to manage costs for the car owner while keeping an eye on potentially unsafe speeds.

When engine builders can’t use modern techniques to actually increase horsepower, they’re often limited to finding lost or missing horsepower. One of the best ways to free up those ponies is friction reduction in the engine and drivetrain.

On the other hand, in classes where rules are much more flexible, racers have been cranking up the boost and creating high-stress conditions that can damage expensive components.

That’s where companies that specialize in lubricants have been developing and testing very specialized formulas to meet specific needs of the racer, whether in a rules-restricted or open class.

“In the past few years, I’ve seen more attention to application-specific products,” said Kyle Fischer of Lubrication Specialties, Mt. Gilead, Ohio. “Some of the modifications that guys are putting to these cars are really pushing the limit. When you find new problems, you find new solutions.”

There are also relatively untouched territories, such as within diesel and powersports, where lubrication issues can be different than in traditional motorsports.

“We do a lot of R&D with our diesel race teams because they take these components further than they’ve ever been,” added Fischer. “But as a manufacturer, I wish we talked more within the industry.”

Fischer told the story of meeting a shock absorber specialist in one of his racer’s pits. He learned of a consistent failure issue but also discovered that there was no hardcore science behind the selection of the oil in the shock absorber. Fischer visited the shock company’s trailer to see the problem up close, and after conferring with his engineer back home, they agreed on a potential solution.

“We’ve known how to fix this problem for years, but we’ve never talked to a shock absorber company to know that a problem existed,” said Fischer. “The shock company has great test equipment, and we’ll do a lot of testing with them and hopefully formulate a great solution.”

In another example, Fischer was talking with a racer who ran a blown alcohol engine and bemoaned that he was changing the self-contained oil in the supercharger after every run. After further discussion, Fischer learned that the constant oil changes weren’t because the oil was breaking down, but because the racer feared worn metals were being deposited in the oil.

Manufacturers that specialize in high-performance fluids and lubricants have been developing very specialized formulas to meet specific needs of the racer, whether in a rules-restricted or open class.

 

“So, let’s try to fix the problem and use an oil to reduce the wear and extend the life of the oil in the supercharger,” said Fischer. “You know, we stay in our lane. We’re a lubricant company. We’re in the lab and at the track, and we want to know what kind of problems racers are having that a lubricant can fix.”

With all the choices in the market, racers need to be aware of the technologies behind a product and its intended use. They should know what the manufacturers have learned: the application will dictate the chemistry. The very best gear oil, for instance, makes a lousy engine oil.

That attitude is well represented throughout the lubrication industry. What follows is a sampling of companies that have developed unique products to address specific problems.

 

Tri-Ex2 Grease & Gear Oil
TriboDyn Lubricants

One NASCAR team was experiencing drive-plate failures, especially on high-banked tracks where the load is brutal on the right side. The team was replacing the plates as often as every other race.

“With our ceramic technology, we made them a grease that would solve the problem,” said Mark Wheatley of TriboDyn Lubricants, Mooresville, North Carolina. “We haven’t had a failure since, and at least 16 Cup teams are using it.”

The Tri-Ex2 extreme temperature and pressure grease is also good for wheel bearings and other components under high-stress conditions. It leverages the same ceramic coating technology used in TriboDyn’s engine and gear oils.

“We heard from racers running quick-change rearends, and they complained that they couldn’t change gears without wearing gloves,” continued Wheatley. “Our Tri-Ex2 full synthetic gear oil works so well, it can lower the operating temperature up to 80 degrees.”

The gear oil is offered in 75W-90 and 75W-140 viscosities and is suited for differentials, manual transmissions, transfer cases, and other gear boxes that require a lubricant. The patented ceramic lubricant features a complex mixture of gear lubricants, combined with synthetic base stocks, and a sulfur-phosphorus extreme pressure additive package with friction modifier. Wheatley explained this formula provides thermal and oxidative stability, as well as anti-foam, anti-rust, and anti-corrosion protection.

 

DBR & HVL
Driven Racing Oil

While Driven Racing Oil’s High-Viscosity Lubricant (HVL) has been around for about 12 years and is popular as an engine-assembly lubricant, the company recently gave the product a freshening.

“HVL is a legacy product that we recently updated with the Pennsylvania base oil that’s in our GP-1 high-performance oils,” said David Chamberlain of the Memphis, Tennessee-based company. “It makes for a phenomenal assembly lube because it has a natural cling and tack. It’s going to stay where you put it.”

The upgraded assembly lube is a non-foaming product and blends well with the break-in oil, extending the oil film thickness during that critical period. HVL is also a perfect segue into Driven’s latest product, a 15W-40 break-in oil for diesel engines.

image 3
Driven Racing Oil’s High-Viscosity Lubricant (HVL) has a new revised formula. It now uses the same Pennsylvania base oil as the company’s GP-1 high-performance oils, improving its effectiveness as an assembly lube, said a company source.

 

“Driven pioneered specific break-in oils for gas engines,” said Chamberlain. “This DBR formula piggybacks much of the same chemistry, but it has a much more robust dispersant package.”

Diesel engines are notorious for producing soot, which are micro-sized pieces of hard carbon. Soot-related wear can be found throughout a diesel, especially in places like the timing chain or other areas with tight metal-to-metal tolerances.

“With a diesel, the soot has to be managed,” explained Chamberlain. “We want to keep the soot suspended in the break-in oil. It shouldn’t fall out into the component.”

According to Driven Racing Oil, diesel engines can run the break-in oil longer than what is recommended for a gas engine. That’s because of the lower rpm levels, and diesel engines have larger sumps for greater oil capacity.

“However, we suggest changing the filter after about 60 miles to pull any metallic particles out of circulation. Then you can go about 800 miles before draining the break-in oil, changing the filter, and switching to a conventional oil,” concluded Chamberlain.

 

Supreme 7000 Synthetic Plus 20W-50
Schaeffer Manufacturing

The Supreme 7000 Synthetic Plus 20W-50 race oil is a high-zinc formula designed as a general-purpose racing lubricant and can be used in select four-stroke motorcycle and ATV engines. The foundation is a high-quality, para-synthetic base stock that is mixed with an additive package and shear stability viscosity index improver.

“Supreme 7000 Racing Oil 20W-50 is fortified with Micron Moly and Penetro, our proprietary friction modifiers we use in all our engine oils,” said Dawn Cross of Schaeffer Manufacturing, St. Louis, Missouri. “Those friction modifiers are key to protecting race engines operating in extreme driving conditions. In addition to the friction modifiers, Supreme 7000 Racing Oil 20W-50 is blended with extra zinc to further protect flat-tappet cam engines and other components.

“Each season we hear from racers who tell us how impressed they are with the condition of their engine at the end of the season,” said Cross. “The results are the same: Engines are clean with little to no wear. Some racers report their oil temperatures are consistently 10 to 15 degrees cooler than with other lubricants.”

 

OxyCrate Racing Fuel
Klotz Synthetic Lubricants

A number of Late Model racers on both dirt and asphalt were encountering exhaust valve recession on their aluminum heads. To combat this problem, Klotz Synthetic Lubricants in Fort Wayne, Indiana, partnered with Hendren Racing Engines in Rutherfordton, North Carolina, to develop OxyCrate racing fuel, which is optimized for the 525, 602, 603, and 604 crate engines from GM Performance.

“Severe valve recession can impact valve lash and restrict exhaust flow,” said Jeff Streby of Klotz Synthetic Lubricants. “This reduces engine performance and increases maintenance costs over time.”

Streby said Klotz’s fuels offer measurable increases in horsepower and torque but were never designed for the unique durability requirements of modern crate engines. The company leveraged knowledge working with the Indy Racing League in the 1990s to develop a new race fuel.

Using a chassis dyno to validate the formulas, the new fuel showed an increase of 8 horsepower at 6,000 rpm over comparable fuels.

“We achieved horsepower and torque objectives early in the fuel’s development,” noted Streby. “However, several iterations were needed to achieve the desired hardware protection.”

Klotz engineers discovered a blend of its current products delivered the performance goals. Those products included its base high-octane fuel, a proprietary oxygenating additive, and Uplon, a Klotz product sold separately as a fuel lubricant that adds surface-active, anti-wear chemistry to the formula.

 

Supercool
Red Line Synthetic Oil

With power adders becoming more popular on both factory production cars and race cars, managing heat is always a concern. The Supercool performance coolant from Red Line Synthetic Oil was developed to serve a wide band of performance applications.

“As OEM manufacturers were offering more factory models with power adders, our customers were looking for ways to keep their engines cool and protect their investment,” said Mark Beatty of the Benicia, California-based company. “We launched Supercool to fit all makes and all models versus OEM fluids that only fit a narrow range of vehicles.”

Supercool is designed with better heat-transfer properties compared to glycol-based antifreeze. It comes as a 50/50 ready-to-use premix and is compatible with gas or diesel engines found in tow vehicles.

“When used with supercharger heat exchangers, it helps keep the system cooler and takes longer to heat soak a water-to-air intercooler,” added Beatty. “Our formula enhances the fluid’s ability to transfer heat, reducing operating temperatures by up to 20 degrees F.”

Beatty also said Supercool will clean and lubricate water pump seals and can be used in systems with aluminum, cast iron, copper, brass, and bronze components. A formula is also available for the powersports industry.

“We are in the business of helping people protect their passion, no matter if they show it, cruise it, race it, or push it to the limit,” added Beatty.

 

Pro ATF 10, 20 & 30
HPL Oil

Fine tuning an automatic transmission and torque converter is a little easier with HPL Pro ATF transmission fluid that’s available in SAE 10, 20, and 30 weights.

“We designed them so you can mix them,” explained Erik Brock of HPL, Hebron, Indiana. “You can add a little 30 if you want to tighten up the converter, or you can mix them to achieve the reaction that you want for track conditions.”

Engineered for racers who were experiencing problems due to high-heat or high-stress conditions from boosted engines, the formulas are designed to reduce clutch slippage and provide more consistent fluid behavior with temperature swings.

HPL Pro ATF transmission fluid is engineered to handle high-heat and high-stress applications. It’s available in SAE 10, 20, and 30 weights that can be mixed to alter transmission and converter characteristics.

 

“We built our Pro ATF from scratch for extremely high temperatures,” explained Brock. “Racers with turbo cars trying to spool up on the brake can build 100 degrees a second, and that can kill the trans oil. We designed the Pro ATF so it wouldn’t be such an issue.”

Formulating a new ATF often leads to compromises or tradeoffs in different areas of performance. “We knew the limitations of current chemistry and experimented with chemistries and technologies,” said Brock. “When building an oil, any oil, a change to the chemistry a tenth of a percent can affect another part of the oil. For example, a change in chemistry to improve anti-wear properties can completely wreck anti-foam or corrosion resistance. Our main goal was to build an oil that wouldn’t fall apart in a race vehicle with high temperatures.”


LX4 Lubricity Extreme
Hot Shot’s Secret

When engineers notice problems in company-sponsored race vehicles, work on solutions tends to begin right away.

“We developed it after we found problems on our diesel race trucks,” said Fischer of Lubrication Specialties, the manufacturer of Hot Shot’s Secret’s LX4 Lubricity Extreme.

The problem was sourced to the Bosch CP4 fuel pump, which replaced the CP3 in many diesel applications, including GM, Ford, Ram, and Jeep.

image 5
Hot Shot’s Secret LX4 Lubricity Extreme is formulated to boost the lubricity of diesel fuel, making fuel pumps last longer, according to a company source.

 

“But the CP4 was developed based on Euro-spec diesel fuel, which has higher standards than our ULSD [ultra-low sulfur diesel] domestic fuel,” said Fischer. “We have a much looser standard, which allows for a drier fuel. Where this really showed its face was at the track in the diesel series. Racers were asking why they were burning up fuel pumps so fast.”

Hot Shot’s Secret reached out to industry insiders and conducted tests with a lubricity agent on both the CP3 and CP4. Basically, the process of removing sulfur also removes nitrogen and oxygen, both of which helped improve the lubricity in diesel fuel. Part of Hot Shot’s Secret’s secret was to return oxygen to the fuel, which has no effect on the environment.

“We really needed to get the lubricity levels in the fuel up. The fuel is the only thing lubricating the pump,” noted Fischer. “The trick is to bring up the lubricity without affecting the cetane. Racers still need to make power with the fuel but also protect the components in the fuel system at the same time.”

 

Pro Max ATF
LAT Racing Oils

There’s no doubt automatic transmissions are bearing the full brunt of tremendous horsepower gains of the past few years, and that has sent lubrication engineers to the lab to find better ways to protect those parts.

“An ATF can fail because of high horsepower and high heat,” explained Danny Vaca of LAT Racing Oils, Orange, California. “With our Pro Max ATF synthetic, we built it from the ground up to be robust to fight heat issues and help the transmission live through the tortures of the turbo and supercharger cars.”

image 6
LAT Racing Oils’ line of synthetic ATFs is available in Pro Lite, Pro ATF, and Pro Max ATF, engineered for different transmission and converter setups.

 

LAT offers three blends of ATF. The Pro ATF is the base formula with a viscosity index of 210, while the Pro Lite recipe has a viscosity index of 165 and is designed for reduced drag and loose torque converters. The Pro Max ATF is built for high-stress conditions that require higher shear resistance, faster lockups, and smoother shifts.

“When I tell them how much it costs, they say that’s triple what they normally pay for ATF,” said Vaca. “Then I ask how often they change transmission fluid. Sometimes the answer is after every race because the fluid has gone bad. Basically, I got them to answer their own question because our formulas will live much longer.”

 

Speed Sauce and Speed Sauce Plus
VP Racing Fuels

World War II piston aircraft used to inject a mixture of water and alcohol into the intake manifold to help control knock, and that same trick is still being used today with high-boost turbocharged engines.

“This ‘charge cooling’ fluid not only cools the hot compressed air coming into the engine but also acts as octane on demand due to the high-octane rating of alcohol,” explained Mark Walls of VP Racing Fuels, San Antonio, Texas, which markets two versions of a water-injection formula. “Over time, the racing world adopted this technology, followed by a few production cars, such as the BMW M4 GTS.”

image 7
VP Racing Fuels’ water-injection formulas are available in two types: Speed Sauce, with a 50:50 methanol/water blend, and Speed Sauce Plus, with 80:20 ethanol/water.

Today’s typical mixture is a 50:50 blend of water and either ethanol or methanol. The formula in VP’s Speed Sauce is one part water, one part methanol.

“Methanol is used due to its high octane and latent heat of vaporization,” explained Walls. “VP Racing started looking at other alcohols that potentially could maintain or improve upon the benefits of the water/methanol blends without some of the downfalls, such as toxicity, corrosiveness, and lower energy content.”

VP then settled on an 80:20 ethanol/water blend for its Speed Sauce Plus, using ethanol for its increased energy content, higher octane, safer handling from a toxicity standpoint, lower corrosion, and offering up to 100% renewable content.

“While choosing blends of alcohol and water, a balance of charge cooling and octane tradeoff will be realized,” added Walls. “Testing at VP resulted in a mixture that gives ‘enough’ charge cooling and the right amount of octane on demand to deliver up to 5% more power than the water/methanol blend while using up to 30% less product. While looking at stock performance vs. alcohol injection performance, we were able to increase horsepower from 425 to 522 (turbo limited) and torque from 406 to 621 lb.-ft.”
