I got the 2 stroke 80cc. New motor. Some good oil brands I can use? Hope this isn’t a duplicate post. Are there some good ones I can get at places like Autozone? Thanks in advance.

Rusty the oil you use should be for air cooled engines, I think it depends on what's available near you. I have had good luck with Lucas semi synthetic mixed at 32/1. Oils for chain saws are usually good as well.

Ok. That brings up another question... I hear about all these different oil mixing ratios for new engine break in so I’m not sure who’s right when it comes to the 80cc 2 stroke. What ratio should I use for break in?

Your engine is really a 66 or 69cc by US standards, I recommend 24/1 for break in, then 32/1 after about two gallons. Some people run different ratios and that's their option, for me I keep my fuel mix simple so I can use it in everything I have that is 2 stroke.

Most of the data that comes with the kit is reprinted over and over, some of the newer kits now recommend 25/1 for break in. The 16/1 was the standard many years ago, back then a lot of people used 30w engine oil to mix.

How long should my break in period be? Hours? or gallons?

LOL, back in my days, like you said 30W oil was all there was, no 2 stroke oil till latter. And the old 1/2 cup to gal. stuck for many years..Think that's way the stuck with the 16 to 1 on the china engines, still a lot of old engines being used over there, also. Yes 32/1 after break-in at least, i don't have china engine, but chain saw and all run 40/1 Sthil oil. ...........Curt

every body has their formula but i would use what the manufacture suggests just in case. I use 20/1 regulars 2stroke oil for break in then i use 40/1 with pure synthetic 2stroke oil i always run 87 octane or regular gas

I use good synthetic 40 or 50 to one mixed at about 25 to one. They burn real clean so I don’t see any reason not to have a little more than needed and not a little less. I f you discover you are running too little oil by the way the engine is acting it’s already too late to save it.
