Engine oil VALVOLINE or AMSOIL

I switched oil to AMSOIL signature series synthetic, from everything I read, it out performs other oils, used to use Mobil 1

i honestly have no way to prove if it works, but i started using it in my ‘98 corolla about 20k mi ago (known for burning oil due to flawed piston design) and have noticed a significantly lower oil consumption rate, which was almost 2qts every 5k down to less than half

I normally dont buy into stuff but my vette was burning oil, Id see a big cloud of blue smoke after I let off after every pull, few thousand miles of this stuff and I stopped seeing it.

That stuff ROCKS! Cured my stuck piston rings issue on my 201O Acura J37 engine.

It works. It’s a quality oil that I use in my daily 5.0 S550. Used in my 200k mile 2.0L turbo fusion and the first oil change was so gross. Blow by has gone done a lot.

I've used it for about 25k miles in my Camry with the 2AZ-FE engine (200k miles on it), it has the known issue with the piston rings being poorly engineered and seize up from excessive oil burning. I can personally confirm it has cleaned up my pistons, I haven't taken the engine apart so can't directly see the rings but oil consumption has reduced from 1 qt per 1k miles to now 1qt per 5k miles.

It sure does work, cleaning dipsticks and reducing oil burn has been my experience on several personal cars since starting a year ago. I bought an MDX burning almost 1 quart oil / 1k at 155k, now doesn't use a half quart every 3k now at 185k.

I've been using valvooine max life for a long time and it's done me just fine.

My biggest regret, not swapping out the shitty 0w-20 factory filled oil for some 5w-30 Amsoil, Motul, or Pennzoil Ultra platinum the moment I took it home. Don\u2019t wait till 1k miles.

Get a catch can but that mobile 1 oil you are using is for shit . Amsoil is best for mustangs and the best for that matter period it\u2019s cost but you can run it 25k
