Engine oil PENNZOIL or AMSOIL

Amsoil Signature 5w-30

My car burns oil and I went to Pennzoil ultra platinum. Burns ways less oil now

It’s probably placebo but I feel that I burn less with Amsoil. That said with current prices I’ve gone back to my default of Castrol.

Pennzoil Ultra Platinum is one of the best full synthetic oils out there.

Liqui-Moly is also good, as are Amsoil and Pennzoil Ultra Platinum. I never had good luck with Mobil 1.

O-w20 amsoil is top notch, expensive but worth it.

I use Amsoil in every vehicle with an engine that I own...this has not changed for 25 years. Amsoil is so good I'd pour it over pancakes if I ran out of syrup.

I keep a running supply of pennzoil ultra platinum 5w30 around as 4 of our vehicles use it. I start to worry when I have less than 10 quarts.

Pennzoil because it runs about 20°F colder for me.

Pennzoil. I've run conventional, semi synthetic, and full synthetic. Nearly 200k miles, still kicking like a mule. 7500 mile oil changes on the reg, some to 9000. No signs of slowing down.
