Ok guys, sound off on who uses Opti-2 Two cycle oil please. Love to hear from lawn crews too. Any blown/locked up engines out there from that 100:1 recommended mix?

I have a husky 371 that I got from a logger who seized it on opti 2 at 100:1. It wasn’t too bad to get running again. He said it had a lot of hours on it so it was the guinea pig for the opti 2 trial so who knows if it was just the oil at fault. He normally runs everything at 32:1 fwiw.

What OPE says to run at 100:1? I use 50:1 premix for my two cycle Husqvarna OPE.

I have a lawn biz and used this stuff for a few years. its wayt o expencive for high volume use. best thing about it was little to no smoke or smell. amzoil works better and smells great too. used mine at 80/1 couldn't make myself use 100/1. I now use reg 2cycle oil as the cost is much lower. never had a engine failure with opti 2 -just cost way too much.

100:1 is the manufacturers recommended ratio for Opti-2.

I'm with you, all mine say 50:1 too.

Ok so we have a possible related oil failure here. Old saw, I get it....... Only thing new was the Opti-2 oil. One more reason for me to stay at 50:1 in all my gear.

When I was a teen and I raced 3wheelers I was sponsored by Neo synthetic oil. It was to be used @ 100:1. I could not keep my engine together @ that ratio.

I went back to golden spectro @ 40:1 and never had another problem.

He's another first hand testimonial of a failed oil mix, thanks to Chris142. Now we have two failures at insane 100:1 oil mixes.

Why is it the oil makers (Interlube and Amsoil) claim 100:1 and not the engine manufacturers?

What manufacturer? Of the Opti-2 oil or the OPE manufacturer?

i suspect that a 100:1 ratio would work with a high quality oil and perfect jetting. Keep in mind that temperature,humidity etc have a slight effect on jetting. Most of us do not have the necessary equipment to adjust jetting every day or more than once a day. We also do not want to be bothered with it.

So we choose a safer mix ratio of 32:1,40:1 or 50:1 all of which give good engine life without the need for chasing jetting.
