I never even thought about it before reading it on this forum.
Any Pros and Cons?
I use high test I think the mowers perform better but it cost more, so now i use the thought gass is gass.
the only con I see at the moment is almost $2.83 gallon for premium. I'll pass.
If the engine is designed to use regular, USE regular.
Most people think you get more power from premium, but that is false. The BTU content is the same. The difference is that the premium fuel burns more slowly, reducing the chance of detonation. Detonation is a problem with high compression or boosted engines. Low compression engine, run low octane gas.
i use to use high test on everything except the trucks, but with the rising fuel prices last year I put high test in the mixed gas and everything else got regular
Regular it is.
Stihl recommends using mid grade gas in their trimmers, so that is what all of my equipment recieves.
Ditto on the regular unleaded. And also, don't go by "so-n-so recommends mid grade" well what IS midgrade?? It's all about octane levels. Here it's 87, 90 (with 10% ethanol) and 91 octane. Some parts of the country it's 85, 87, 91.
Most small engine books will give a minimum octane rating to be used, I think 87 is standard, and that would be considered "mid grade" if you live in an area that offers 85.
i use high test in my 4 stroke equipment . you get a better gph .
I use regular in everything, except the walker
