Just for curiosity

Mobil 1 5w40 on in my truck since new. 63k miles zero issues 5,000 OCI

[Mike Honcho]

Mobil 1 0w-20

[BrutalNoodle]

Rotella T6 5w40.

Of all the name brands, including the expensive Red Line, the turbo boxer seems to operate smoothest with it.

I ran rotella T6 in my subaru with great results

Ran mobil1 for 12k in my camaro. Changed it to AMSOIL

I will never run anything else in any vehicle I own. I've been changing my oil on my motorcycles and cars/trucks all my life. Never observed such a drastic improvement.

I immediately noticed improved revving, reduced oil consumption, improved mileage, motor just seems properly lubricated COMPLETELY.

I can't recommend it enough AMSOIL AMSOIL AMSOIL

Great oil AMSOIL is. No argument there. Can't convince myself the cost of AMSOIL is worth it over say Mobil 1 Extended Performance or Pennzoil Ultra Platinum when changing oil every 7 to 10k miles yearly.

[Hammer77]

Pennzoil Platinum 0W-20

[Eldorado2k]

Regular Pennzoil 10W 30.



179,000 miles and no leaks. [which is pretty rare for a Cadillac].
*knock on wood*

[Paul A.]

Mobil 1 or Castrol 0W-30.

Not to divert but can anyone recommend a favorite vendor for analysis? I have heard Blackstone is decent.
