PTH Racing Oils
Let’s face it: All Oils Lubricate
The question is for how long and under what conditions? Stock motor oils work for stock engines. But when you install a higher lift cam and stronger valve springs you need better oil.
Stock motor oils work for stock engines. But when you install a higher lift cam and stronger valve springs you need better oil. High-performance engines see more RPM, higher loads and increased temperatures compared to stock engines, so a high-performance engine requires higher levels of zinc, phosphorus, sulfur and other additives to prevent premature part failure. This is especially true in flat tappet lifter engines. Simply put, the oil used in the engine needs to be formulated for that specific type of engine.
Creating a True Racing Oil
Almost six years ago we set out to make a racing motor oil with one thing in mind: develop the best product possible.
We started by looking at the best products on the market (a very big market), then one by one, we started evaluating each company’s oil products. We did viscosity index testing, cold cranking simulator tests, API gravity tests and probably the most important metals, also known as anti-wear additives, testing.
We tested not only racing oils but high performance conventional and synthetic passenger car motor oils. To confirm what we were finding, we sent many samples to outside independent laboratories. The most common thing we discovered was, most of the racing oils on the market, are NOT true racing products.
To be a true racing oil, you need without exception, an oil that holds up to the high temperatures and stress of a high torque and high horsepower motor. Racing oil must be built with high-quality base stocks.
It must have a higher ratio and combination of key components, not found in standard additive packages, including, friction modifiers, friction reducers, anti-oxidants, base number boosters, extreme pressure additives, anti-foaming agents and in some cases anti-misting additives.
We sought to develop a lubricant that would endure the rigors of endurance racing while producing more power by reducing operating temperatures within the engine, and offering a greater level of engine protection. Our formulation and chemical compounding was optimized over a dozen times since 2012, until the final formulation was derived.
The Best Base Oils on the Planet
PTH Racing Oil is a combination of two different synthetic base fluids, including synthetic esters, polyalphaolefin (PAO) and alkylated aromatics. Whereas conventional oils contain molecules of varying sizes, the molecular structures in Group IV and Group V synthetics are consistent in mass and shape. This uniformity means those molecules create less friction as they collide, and less friction means less heat:
- Measurably better low- and high-temperature viscosity performance at service temperature extremes.
- Better chemical and shear stability.
- Decreased evaporative loss.
- Resistance to oxidation, thermal breakdown, and oil sludge problems.
- Extended drain intervals with the environmental benefit of less oil waste.
- Improved fuel economy in certain engine configurations.
- Better lubrication during extreme cold weather starts.
- Can provide longer engine life.
- Superior protection against “ash” and other deposit formation in engine hot spots (particularly in turbocharged and supercharged engines) for less oil burn-off and reduced chances of damaging oil passageway clogging.
- Increased horsepower and torque due to less initial drag on engine.
The two primary synthetic oils are polyalphaolefins (PAO) and esters.
PAOs, categorized as API Group IV and Group V base oils, are initially derived from ethylene, which itself is a colorless, highly flammable hydrocarbon gas. Ethylene is chemically processed by oligomerization into linear alpha olefins that are then converted into polyalphaolefins (PAO), which is used as the base oil for most fully synthetic oils.
Esters, made from an oxoacid reacted with a hydroxyl compound such as alcohol or phenol, belong to API Group V base oils and have excellent lubricity and high-temperature resistance. They are more expensive than PAOs and not commonly used as the base oil for synthetic motor oil but rather as an additive. However, ester oils were the basis of the first jet engine lubrication oils and are still used as such due to their thermal resistance to temperatures of 400ºF while retaining the ability to flow at very low temperatures.
PTH Racing Oil – Pacific Throttle House in Sand City CA
Mike Sweeney is a Professional Driver in Grand AM and owner of Pacific Throttle House saw the opportunity to help test and bring to market a racing oil that was designed specifically for the extreme conditions of endurance racing. Mike wanted to see an oil that was world class in its base oils and additives, but more affordable for the weekend club racer
PTH Racing Oil began testing our oil in practice sessions and then in competition at the beginning of the 2014 season. Tatum team driver and car owner, Darrell Troester agreed to use our oil in his Porsche GT3 Cup car for the entire season. The Team noticed an immediate improvement in lap times on their home track.
