Engine oil LIQUI MOLY or AMSOIL

I currently use Liqui Moly 5w-40 in my 02 WRX and it loves it.

I run the 5w-40 amsoil diesel oil in mine. No issues whatsoever.

My GT350 gets Amsoil. Had no issues with either one.

Using the same oil but 15W50 for Himalayan. Satisfied with the performance. Even after long rides, the engine feels crisp.

used Amsoil 5w20 last oil change and just did an oil change at ford with motorcraft due to my poor planning… typewriter tick is back with this oil. Didn’t have that at all with Amsoil.

Having recently transitioned from Motul 7100 to Amsoil Metric 10W40 for my Yamaha MT 15, for about 4000km I sought an oil that could deliver reliable engine protection and smooth operation. here are my pros and cons

I like this oil, I believe it was Castrol Syntec from the factory (says so on the oil cap) but it became slightly hard to find and the Liqui Moly has been great oil so whatever. I changed my oil last year at about 9500mi and it didn't even get dark until about 7k miles.

My B9.5 S5 went through a quart about 3000 miles into the last oil change. This oil change that im on now I havent had the light come on and im at about 5000 miles which is when I change oil. I started taking mine to an Indie shop and they use Liqui Moly oil plus they add this little bottle of addative thats supposed to help lubricate the piston rings better.

I run OW-30 Liqui moly that doesn’t burn any oil either.

I use Amsoil. While not on the official VW list as an approved oil, it is never the less formulated to the VW spec.
