Owner reviews for engine oil

My 05 Corolla had one oil change at 800 miles, one at 10,000 miles, and then once per year for 14 years until it was totalled at 330k miles.

I\u2019ve been using Amsoil Sig Series ever since my first break-in oil change. I used it in my old turbo Cobalt SS that I drove like a jackass when I was younger too. Never had any engine issues and Blackstone analysis shows that up to a 4,500 mile oil change interval is safe for my WRX.

I've been running cheap Rotella T6 for 20 years with modified STIs, zero issues.

Amsoil always over anyone. I started with AMSOIL in 2004 and after pulling my Hayabusa Engine @ 20k miles to build for a turbo kit, the engine teardown was perfect, the block, pistons and bearings looked entirely new.

Always used Castrol in my cars when I\u2019ve had the choice and never had a problem.

Have noticed on several times that when I went from Subaru OEM oil to Amsoil BACK to OEM that it runs much quieter and smoother on Amsoil.

Pennzoil Ultra Platinum has some of the best cold flow characteristics so I'm not in a hurry to change it even though it's 5W-30.

Have it in my N55 and it's very happy.

Kupio sam par puta Total 9000 kad sam na\u0161ao u trgovini i mislim da je auto potro\u0161io vi\u0161e ulja nego kada ulje kupim u trgovini sa autodijelovima.

And that mobil 1 stuff is yess ,, ass. I learned the hard way. Its like water tbh.
