Engine oil OEM Toyota or AMSOIL

AMSOIL Signature Series 5w-30 with a black JDM Subaru Filter is the superior combo.

I recommend Royal purple XPR, or amsoil zRod.

I put all the oils people be recommending into the ai to compare with the data sheat information from the manufacturers websites, amsoil still comes out on top ????

Amsoil makes separate oil for all 3 holes....I use them.

Being an AMSOIL dealer and my enthusiast knowledge of vehicles (not a master by any means), I would say that the consumption is very normal due to the very thin viscosity of 0w-20 oil.

Amsoil. I run it in everything I own.

Use toyota 0/16. Or Mobil 1 0/16. Liqui moly is also very good.

My T/A 392 has seen 311°F. ????. I added a bigger oil cooler after that.

I was running 0w40 Amsoil Signature, no metal in the filter.

I did have a 1982 diesel Jetta go 435,000 miles on oem int. shaft bearings. I had access to a lot of free Amsoil back then....so, that may have helped. However, I think it over-lubed the cylinder walls though. Rings weren't exactly what you would call 'tight.'

personally, I think Amsoil AFL is junk. They ruined a stout oil when they reformulated it to mimick 505.01.
