Engine oil OEM Toyota or AMSOIL

I switched to 5w-30 instead of the factory spec 0w-20 and that slowed down my consumption. I use Amsoil to maximize protection with use of the "wrong" oil weight and I monitor wear with oil analysis and seem to have no change in wear from my 0w-20 use.

i use AMSOIL 0-20 in my Vezel. Runs great, maybe slightly better them LM.

I used Amsoil Signature when I was driving 1300 miles a week just so I could go two months between oil changes.

I change oil once per year, using a high-quality synthetic that meets specification 504. I generally drive 8 to 9 thousand miles per year. The maker of the oil I use (Amsoil) says to follow the car maker's change interval.

For me at least, I use a 5w-30 Amsoil on my TLX Type S.

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.

You can use Amsoil just fine, one of the best oils on the market.

You're paying for the name.

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.
