Opti-2 for 2 cycle.... good or bad

[Al Mac]

I picked up some 2 cycle oil yesterday. The dealer said this Opti-2 stuff will do all 2 cycle motors no matter the mix ratio. One mix for all motors. They have been using it for a few years (not sure how many) with no issues.
Any one else use it and what is your thoughts on it.

Opti-2 is top notch 2 cycle oil.Use it with confidence.

I agree with coobie, been using it for years on all my 2 cycle stuff. Also if you use the 4 cycle oil from the beginning on a new engine, the Opti company will double the factory warranty.

Tkx for your input.
I will give it a try with confidence.

I don't like pouches as there is more left that you cant rinse out. but I mix at 32:1 so there would be some fudge error.

I buy my oil usually in quart bottles and mix it up a gallon or two at the time with a ratio bottle and rinse the bottle out after I measure.

I'm comfortable that you can mix it at 50:1 for 2-cycle engines that use that mix, 40:1 for 2-cycle engines that use that mix, 32:1 for 2-cycle engines that use that mix. But no way would I just mix up 40:1 and run everything on it even if it didn't call for that mix. One two-cycle oil?-yes; once two-cycle mix?-No.

Hope that helps!

Why not? Any two stroke running and TUNED properly should run fine at 50:1 or 32:1. Exceptions exist with fixed jet applications etc but most guys that are into two strokes and build the engines would never run one at 50:1 there is just not enough oil on parts like piston skirts and more importantly in the bottom end. The swap from 40:1 to 50:1 was done to appease EPA emissions restrictions and had nothing to do with engine warranty, build construction or oil make up. One year stihl recommended 40:1 on all saws and the next it went to 50:1????? HMMMMMM they had been making the same saw model before that swap and the same oil before and after, so why after all those years switch?

I run this oil at the 50 to 1 ratio as recommended. Use it for everything I own. Buying 93 octane at the pump. I run 5gallons into the truck= fill my gallon can and off I go. Runs fine even in a very old 1050 Homelite chainsaw,string trimmers and Mantis tiller. They do not smoke or run rough. If you run the gas out at end of season, they will start in the spring without the carb work. Even run it in a 465 Yamaha dirt bike.

The quality of oils have come a long way since the 70's. I have been using quality 2-cycle mix at 50:1 since the 80's and have not had a problem. Just remember when you change from a 50:1 mix to a 32:1 mix your fuel to air ratio gets LEANER! The more oil molecules going through the carburetor jets limits the gasoline molecules = LEANER.

oils was recommended at 40:1 long after the 70s read 90s!! I wasn't even alive in the 70s! Nor am I using 70s era oil. Currently I am using Amsoil Saber at 32:1. Nor am I using it in 70s era saws! My main saws are a stihl MS650 (84cc) and Husky 372xp. Both are professional saws and yes I probably cut more wood than the average guy out there.
