Engine oil Kendall or AMSOIL

I’ve run amsoil in all my bikes and still do. Same with all my cars and trucks. Never had issues

For me amsoil signature series 0w20 a lot better than ravenol ehs 0w20.

I'm regularly using amsoil ss on my Honda L15z1 engine almost 7 years.

0W-20 Amsoil Signature Series 100% synthetic oil changed every 5k miles. Wix 57173XP filter.

As an avid user of AMSOIL, it’s a noticeable difference, amsoil is the king

With Amsoil even if it's not signature series I trust it more than any other 0w8.

I run Amsoil and my oil change interval is 25k so the answer is it depends.

I only use Amsoil Signature Series in my B58.

I changed to that and really happy with it so far, shifting is butter smooth.

i use amsoil saber when i have it but not at 100:1 I don't really care if the engineer says its fine.

I am not hating on Amsoil. I am running their engine oil and ****ing hate it. burned off another quarter of a quart in the last day of driving... ive never had this kind of consumption before and there are no leaks...
