Finally unboxed my new Lazer and after reading either here or in owners manual its suggested to get 91 octane. I am using smokeless oil and switching to cj8y plug. Will also be adding an ounce of seafoam and as for oil going with 40 or 50/1 mix. I did get a gallon of the BP 92 octane but am confused on the leaded/unleaded differences 
Should I use the 89 stuff that is everwhere. Just want her to run top notch! R.D. 2hp tecumsah
I really don’t think it will matter, IMHO seafoam and any oil and gas is more than enough. Sure smokeless is probably better (though the seafoam should negate any negitive side effects of the oil), guess I never paid much attention to the octane rating, Mine’s always ran like a ice eating machine on 87. Maybe if you were out drilling 100’s of holes non stop like for an ice fishing contest, I’d consider something more than 87. I just can’t imagine a person heating that motor up enough to worry about 87-92 with just regular fishing, even if you are the type that punches 100+ holes a day, you gotta stop and fish sometime 
.
Really I’ve done nothing more than add gas oil and seafoam and mine has never had an issue. Starts on the 2-3 pull after sitting for a period of time, usually the first pull if it’s ran earlier in the day.
Use seafoam sparingly. Remember that the oil is added to gasoline for lubrication of metal parts and seafoam will dilute the oils capacity to lubricate. IMO seafoam should be used only if there is a possibility of stale gasoline running through the engine or possibly once per season to remove varnish.

I think I have to disagree with this, pretty much everything I’ve read says differently, (not being an oil technician) A quick search came up with this thead. Seafoam is oil, now it won’t replace the oil you are suppose to mix in, but it shouldn’t in anyway reduce it’s lubrucation ability, (it’s actually suppose to help it) http://romps.com/?p=26 I suppose the proper way to add it would be add the gas and seafoam to a proper level then add the oil, so you have one gallon of gas/seafoam versus 1 gallon plus some seafoam.
And in fact it their claims are true, seafoam may give you the benefit of helping prevent detonation, which I assume is the reason they want you to run 92.
Overall I run seafoam for a couple reasons myself, to make sure the gas is stabilized and to reduce any carbon buildup, I use it as a preventive not as a fix.
I have to say mine lazer mag is a couple years old (3 years)it’s quite possible they have changed the engines a bit since….
All that being said I’ll bet you well within the minority of auger owners that care that much, and should have a fine running machine for many, many years.
