Engine oil MOTUL or AMSOIL

I run amsoil in the engine and primary and redline in the tranny. No issues, my glide runs better on the amsoil then when I the syn3 in it

This is amazing . I have it in my 200 ns and it feels so smooth. There is 300v too but i never tried it . 7100 is best engine oil beside petronas if you can locate it anywhere

The Motul 7100 20W50 is a good choice.

Here I am just dumping in Amsoil 5W-50 SSO because all I care about is shear wear protection and something content with high temp operation. 20,000 miles and not even a single psi drop in compression the whole time, don't even premix.

I refused the engine oil change -as I had plans to go the motul 7100(10w40) route- but air filter needed to be changed and so will the brake pads within the next thousand kms as informed by the service guy. After the service, I could feel a difference in the top end, as in it reaches 110 quicker, but then again might be my imagination.

use motul i have a twin turbo 350 and it runs amazing

I've been using AMSoil 5W30 in my WRX since it was new (2003). Turbo is still good, and head gaskets lasted 17 years. I think it's worth the price.

I use Amsoil 0W20 but I’m a dealer. I have access to the test they run comparing it to Mobil and AC Delco stuff. The Amsoil is supposed to be better longer, but to me that comes down to your filter more than your oil.

I use Motul specific 2290 5w30 full synth, I'll check oil level evey 3000km and add a little if needed, it runs ok

Amsoil allegedly is the best. I use it in everything and no issues so far.
