Verified Purchase

normally use Lucas but went on a long road trip and forgot my bottle. my car requires upper cylinder lubricant. did basically the same thing. A bit more thinner than Lucas so may be better for high compression engines.

Prevention is the best plan

I travel long distances periodically and have to depend on gas stations along interstates so I add a bottle of this to each fill-up on the trip to avoid any issues with unfamiliar gas. Haven't experienced a problem yet, so I will continue to use it.
