PTH Racing Oils
The Finest Oils Available For Your Car

  • PTH Racing Oil was designed to be the highest quality racing oil with no compromises to protect racing engines that are under incredible stress and heat

  • Upgraded internal components are expensive and PTH Racing Oil helps protect these parts

  • PTH Racing Oil was formed 6 years ago between Rick Lee and Thomas Kirkham, noticing there were no race oils using quality base oils

  • Both decided to do independent testing of the existing products, and alarmingly most of the racing oils on the market were not true high-performance products

  • One of the most important requirements is the oil maintaining its chemical lubrication properties, even under intense thermal and physical stresses in engines

  • PTH Racing Oils began with the highest quality base oils, sourced from Exxon, and introduced a number of additives that are not usually found in racing oils due to cost

  • Additives include: friction modifiers, friction reducers, anti-oxidants, base number boosters, extreme pressure additives, anti-foaming agents, and sometimes anti-misting additives

  • Created with combination of two different 100% synthetic base fluids, including synthetic esters and polyalphaolefin (PAO) and alkylated aromatics

  • PTH Racing Oil’s molecules of Group IV and Group V synthetics are consistent in mass and shape, creating less friction as they collide and thus less heat

All oils lubricate, but not all lubricants are equal.

What makes a better oil, and why do you need it? Stock engine oils work just fine for stock engines built for the periodic spirited backroad exploration or occasional track day, but high performance engines pushed to the limit in the name of performance is a completely different ballgame.

When you begin upgrading components that differ from the factory, you expect upgraded performance. These high-performance (and often expensive) mechanical pieces are built to maximize performance at the highest levels, but in turn need to be taken care of. Installing a higher lift camshaft or stronger valve springs requires an oil that can stand up to the increased stress that these performance components are designed to handle. High performance engines see more and higher RPMs, increased loads, and scorching temperatures compared to stock engines, requiring higher levels of additives that protect the components. Some of these additives include zinc, phosphorus, sulfur, and other elements that help prevent premature part wear and ultimately part failure. This is especially true in flat tappet lifter engines, commonly found in many vintage race cars.

Put simply, the oil that should be in your engine should be formulated for that specific type of engine. No compromises in the engine oil equals better protection for your investment.

Creating a True Racing Oil

Six years ago, PTH Racing Oil saw flaws in the ever-expanding market of lubricants: low-quality base oils with less-than-adequate engine protection. While the common adage goes “If you want something done right, you have to do it yourself”, PTH Racing Oil had an epiphany: None of the manufacturers were interested in developing an engine oil that genuinely was several notches above the competition. This led PTH Racing Oil to develop the best engine oil products unlike any other, using the best materials for the best protection of high-performance motors.

PTH Racing Oil started by looking at the best products that were currently available on the market, filled with a labyrinth of claims, shoddy performance figures, and flashy marketing. One by one, each oil from each manufacturer was evaluated to determine a baseline of which oil was in fact keeping with their claims. Tests included viscosity testing, cold cranking simulator tests, API gravity tests and probably the most important, metals (also known as anti-wear additives) testing.

Not only were racing oils tested but high performance conventional oils and synthetic passenger car engine oils as well, providing a wide gamut of data that were invaluable for comparisons and engineering later on. A large number of oil samples were sent out to independent laboratories to confirm the findings that were found by PTH Racing Oil’s own internal testing. The most common and surprising (and alarming for those using those oils in investment-grade high-performance engines) was that most of the racing oils on the market were NOT true high-performance products.

One of the clearest requirements for a true high performance racing oil, without exception, is to have a lubricant that holds up and maintains its chemical properties while under intense stresses of a high torque and high horsepower motor. True for many of these “racing oils”, their special additives designed to protect the engine fell out of suspension (not evenly distributed) under high-pressure applications, thus causing the oil to lose its protecting power. When said and done, all racing oils must be engineered and formulated with high-quality base oils (base stocks).

Beginning with high-quality base oils is like a well-sorted race team: everything works together better and has the capability to far outperform others. In true racing oils, a high ratio of a combination of key components are needed, usually not found in standard additive packages. This includes friction modifiers, friction reducers, anti-oxidants, base number boosters, extreme pressure additives, anti-foaming agents, and in some cases anti-misting additives. PTH Racing Oil was determined to develop a lubricant that would endure the intense stresses of endurance racing, yielding more power from engines by reducing operating temperatures within the engine as well as offering a far greater level of engine protection. PTH Racing Oil’s proprietary formulation and chemical composition has been optimized over a dozen times since 2012, until the final formulation was determined to be the ideal result.

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.
