Engine oil AMSOIL or RAVENOL

1.3 million on Amsoil. Shell is a close second.

Amsoil is worth it and head and shoulders above the competition. I used a custom built testing apparatus to characterize dozens of lubricants including oils of all weights from Mobil 1, Castrol, penzoil, valvoline, and Amsoil.

On my 05 cr125 I ran amsoil low smoke for riding mostly harder enduro stuff (worst bike for it, but a fun challenge).

I got a good deal on some amsoil and I love it, pricey but worth it tbh!

Amsoil z-rod is what I run but nothing wrong with rotella diesel oil.

Amsoil. I run it in anything and everything they make fluids for. Even the 2 strokes. Father has been a dealer for decades and the number of stories he has backing up amsoi's marketing claims is IMPRESSIVE. I've personally seen a few success stories already and PLENTY of scientific testing

Amsoil 5W30 SS, I run E85 so I wanted something I could trust to handle fuel dilution

I personally like Amsoil better they actually created synthetic oil but I don’t believe in 25,000 miles on it oil change if you want to run it for like 10,000 and change the filter halfway through 5000 I believe the Oil Wall hold off no problem bye just seems like a lot of miles to put on oil

AMSOIL ALL THE WAY!!!

Coyote tick is practically gone and I’ve tried Motorcraft, Penzoil, Mobil, Royal Purple, & Castrol. Amsoil is a little more $ but 100% worth it.

Amsoil 10W-30 Signature Series here. It's on the expensive side but it's 100% synthetic, tests great, and made in the USA.
