I have several friends with 250 pro xs four strokes and Im about to have one, they all tell me they do not run any kind of additive in their fuel. Im thinking about doing the same thing I ran all the additives in my 2 strokes and could keep powerheads from blowing, just wonder what everyone thinks ?
I think you will get all kinds of answers, just like opinions on oil. I usually run 87 non-ethanol fuel. It is not "Top Tier" certified fuel, which Don recommends as one of the top criterea. Top Tier fuel usually has a better additive package than non Top Tier fuel for automobiles. So I have always run "Don's coctail" and use 1 oz. each of Quickare and Quickleen for each 5 gallons of gas. My 300R is slightly over 3 years old and 130 hours and so far no injector or fuel related issues. Would the same thing have occurred if I did not use them? No way to be sure, but for me it is good peace of mind for the relatively low cost. I do have direct experience with the effects of E10 on small engines when the fuel sat too long and have cleaned and replaced several carburators on small engines. I now use non ethanol and "Don's coctail" even on my small engines.Originally Posted by Farmerman

Im not sure what Don means by top tier fuel or where a person would get it, we have blown five 2 strokes and I blame it on bad gas
I'd say you better change some of the variables if you've not already determined why you have blown five 2-strokes. Hard to imagine "bad gas" blowing 5 of them and it not being suspected earlier....

Well Don we ran mercury fuel additive dfi oil did yearly service and havent gotten over 200 out of a 2 stroke yet, I wish I knew also
Don, its not like we just blow them up because we have an extra $8000 laying around for a new powerhead
Top tier gas is a certification of sorts for gas a gas station sells, it has to have a certain amount of detergents/additives in it, most major brands of gas are top tier. Check this site for a list: https://www.toptiergas.com/fuel-stations/
