Engine oil OEM Toyota or PENNZOIL

Original owner ran Pennzoil ultra platinum and that I got 289,000 miles on that engine and turbo before I had a shop rebuilt it.

Been running PU since with no problems.

Penzoil the best!

I use Pennzoil platinum euro because its dirt cheap from walmart and meets all specs. 135,xxx kms so far on the same oil.

On 0w16 the engine is smoother, more responsive, quieter and consuming about 0.2L to 0.5L less fuel per 100 km.

Toyota OEM oil is very high quality stuff with lots of wonderful additives that are good for a long lasting engine.

Best bang for your buck is the ultra premium penzoil 0w 20. Meets the api certification and in terms of performance it essentially provides the same level of performance as the amsoil.

I run Pennzoil Ultra Platinum 5w-30. My FK8 is making over 500hp no issues

From my knowledge it doesn't matter what brand you put in. Just make sure its quality oil that's rated for your car and do oil changes regularly. I have used Mazda branded Moly 0W-20, Mobil1 Extended Performance 0W-20 and currently Pennzoil Platinum 0W-20. Honestly I can't tell the difference between them at all.

Brought it in for 5k ToyotaCare at the dealership I bought it from. Used wrong engine oil (at least they listed wrong on the service sheet but promised they did use 0w20) - GRC is only model where 5k or 6 month oil changes are standard. 2500 miles if driven hard. Fucked up the trans oil I asked them to change - used wrong oil type. Fucked up tcase and rear diff oils. Found oil spilled on some pieces of the subframe. Of the 2 test drives they did doing the warranty covered alignment they had 10+ drive pulse hard acceleration /braking/cornering alerts on both 4 mile drives. I changed the engine oil, trans, tacsee, rear diff, cleaned oil they spilt after picking it back up. They said they'd corrected their errors only after I got Toyota corporate involved. I didn't trust them to do anything so corrected all myself.
