Engine oil PENNZOIL or AMSOIL

One poster said it right; Amsoil is a Multi Level Marketing program and that's why it's so expensive. Yes it's great oil, however, the Penzoil ULTRA Platinum is high in detergents that keep your engine clean. It's made of natural gas, an industry first, and is so pure and clear you can hardly see it on your dipstick.

I always run 5w30 Pennzoil Platinum in mine. I have run other brands, but I have settled on this. Easy to get, often on sale, excellent oil.

Pennzoil Ultra Platinum in my 2016 Focus ST. It seems to love it. Quieter idle, great gas mileage, drives smoother after a cold start.

Grab a good quality 0/w20 synthetic. I'm currently using Pennzoil and a Fram filter.

I run Pennzoil ultra platinum oil and GM syncromesh trans fluid

Ultra premium is the best oil after amsoil, but amsoil is too expensive for this car, pennzoil is the best and cheap

After almost 2 weeks of usage, grabe as in grabeeee. napakasmooooth! hahaha tuwang tuwa ako kada throttle kasi mararamdaman mo talaga yung pagkatahimik+ smoothness + responsive throttle nya kaya ang laki ng tinipid sa gas. Kumbaga yung hinahanap ko na smoothnes ng takbo is dito ko nafeel when I start using this kind of oil. From 39 km/l naging 41.3 km/l na sya.

Now, my wife's '16 FORESTER XT, 2.0 turbo, has 130,000 miles, Amsoil changes every 10,000 miles, and still burns NO oil.

Suggested I change oil from Castrol Syntec to maybe Royal Purple or Amsoil.

I would run Castrol over Pennzoil. Coming from personal experience, Pennzoil is junk.
