PQIA Test Results in on two motor oils formulated for classic and muscle cars, and one with POE-PAO baseoil

The following are test results on two samples of motor oil formulated for use in classic cars, muscle cars and other older model vehicles with engines that have flat tappet cams, lifters & pushrods. These products contain higher levels of the antiwear additive ZDDP than that in motor oils formulated for use in most cars currently on the road. For more about such motor oils, see PQIA article, Motor Oils for Classic and Vintage Cars.

CONSUMER ALERT – Mileage 365 Motor Oil

The PQIA recently stopped at a convenience store in Warren, Ohio, and to our disappointment we once again found Mileage 365 on the shelves. Mileage 365 is a product that PQIA has seen on store shelves in Ohio in the past and found it to have deficiencies serious enough that the oil will likely cause harm to an engine. And the samples we obtained during our most recent visit to Warren, OH are likewise deficient.

Motor Oils Are Not All The Same

It’s not unusual to hear someone say, “Motor oil is motor oil, they are all the same.” Although this is far from true, it’s not hard to understand why some might think so. As with many consumer products, the differences between products are often determined by using the senses. In the case of food, for

Motor Oils for Classic and Vintage Cars

The Petroleum Quality Institute of America has from time-to-time encountered motor oils containing high levels of a multifunctional oil additive called zinc dialkyldithiophosphate (ZDDP). This additive contributes anti-wear, anti-oxidation, and corrosion inhibition properties to the oil. ZDDP has been used in motor oil formulations almost universally for decades, and oils with high levels of ZDDP are often promoted as being better suited for engines in older cars with “flat-tappet” lifters.
