Engine oil Shell or PENNZOIL

Pennzoil Platinum Euro full synthetic 5W40 on my Abarth. Same weight as written on the engine oil cap and in the user's manual. 5l jugs easily available for $40 CAD plus HST.

Pennzoil Euro Platinum 5w40. This oil is slept on but out performs most other expensive oils outside of Amsoil.

Nice work. My 2012 camryil4 se gets new oil every 3k 0-20 pennzoil ultra syn. 112,000 mi.

Penzoil Ultra Platinum 0-W20 @3-4K and Mobile 1 Extended Performance Oil Filter. I like that Penzoil derives their oil from natural gas.

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

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.

From what I've learned the best oil for the Turbo of any model with direct injection which Mazda uses is Pennzoil Ultra Platinum.

Use Penzoil Ultra Plat. Can probably stretch it to 5k miles with no issues.

Rotella T6 5w40 in my EJ255, its helped a tad with the leaking until I can get everything apart to seal it all up again.

Pennzoil UP was on a sale and I bought 15 quarts, my Sierra dropped a lifter within 200 miles of the OC and switch, related, no way, will I ever use Pennzoil UP again, no way.
