PTH Racing Oil is formulated with an additive package that includes a high level of ZDDP for anti-wear, with a carefully engineered balance of detergents and mineral additives to protect your engine. See Tech Specs below for each of our oils.
- High zinc formulation provides excellent wear resistance for high rpm, high compression, flat-tappet and pushrod engines
- Engineered to provide outstanding protections in racing conditions.
- Includes friction modifiers to promote maximum horsepower.
- Anti-foaming characteristics to provide consistent oil supply and surface protection.
PTH oils are tested with benchmark equipment to ensure a consistent high-quality performance product.

“Between the results of the Used Oil Analysis and the condition of the valvetrain, it looks like PTH 5w30 is doing a very good job of protecting the fast-moving metal parts within the motor.”
“Even after 5+ hours of time, the motor responded to quick jabs of the throttle just like it did the day after the oil change….”
“…I do like the idea that I could potentially run my engine oil through a 6, 12, or even 24 hour endurance race and not have to worry about protection or power loss. Based on my experience so far, PTH 5w30 seems to be an oil that could do just that.”
