Engine oil AMSOIL or ELF

I have used Amsoil for years and I change my oil every 15,000 to 20,000 miles.

Amsoil 5w-40 in my 3.6 Corrado that gets pushed hard to redline often and has seen somewhat high oil temps when driving harder. I use liqui moly 5w-40 in my 3.6 CC and 3.0T Q7.

if you to go for the best oil and the most expensive ones, you can use liqui moli, valvoline, ams oil

I'm over 50 K on my current Amsoil change. I drive my car a couple thousand miles a month for work. I also put Archoil additive in it when I did the change.

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.

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.'

I have used Amsoil, but I feel as if my motor makes a funny noise with that in it.
