Engine oil AMSOIL or RAVENOL

I am a big fan of amsoil. I purchased a used F150 in 2012 . It had 80,000 miles. The first thing I did was I changed the engine oil, tyranny fluid, and front and rear end lubs to Amsoil. It now has 242,000 miles and just keeps on running.

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 use Ravenol on my 1NZ and 3ZR engines.

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 used Amsoil 5w40 European Car formula or Gulf 5w40 Formula G in my A6 previously. Technically Amsoil doesn't have the have the VW 502 00, 505 00 certifications so I think I will start using Gulf Formula G or GX exclusively in my R, either the 5w40 or 5w30 grade.

im actually running that oil right now... I hate it tbh. 3,100 on the oil and it has allowed excess engine noise since day one, SUPER harsh cold starts, and now its burning through faster than the catrol I ran when I first got the car. a WHOLE QUART over 750 miles. the oil is thinner than piss going in, and it just doesnt stand up to what my engine can put out like Shell Rotella T6 has been doing...
