[This review was collected as part of a promotion.] It works and that's what counts, Penzoil, for all my vehicles needs. Keeps everything running smoothly.

[This review was collected as part of a promotion.] I have always used Pennzoil products for my cars. It is a trusted brand and in my family they have been used for years in all of our vehicles.

My 1988 Mercury Grand Marquis GS is extremely picky when it comes to oil. If I get anything other than Pennzoil, it runs rough and fuel economy goes down. Pennzoil is cheap but extremely great, especially for older engines.

I have always used pennzoil in my cars. That yellow bottle has always given my cars complete oil coverage and decreased the wear and tear on my motor. Continued fan for life!
