Re: What is your choice for fuel stabilizer?
I use Startron Diesel in my farm diesel storage tanks and it works fine to keep algae, caused by moisture in the tank at bay, and the stored fuel immaculate. Problem is nobody sells it around here and I have to order it from the OEM. Yeah it's Naptha (which Naptha???) and enzymes, OEM protected formula, and works. I know of other places where the little "Pac Men" work great and I'm not a chemist so I don't know that they can or can't survive the environment but do know that they work so they must survive.
I never used any fuel additives till I joined this site and heard of Sea Foam. Have been running it ever sense on my 2 strokers and have proven it's effectiveness. I bought a new chain saw and weed eater thinking my existing ones were shot. One day I was bored so I got some SF and revived both of them. I ran my carbs on my Merc. from '04 till '12 without touching them. When I opened them up the inside had zero varnish.
I use Stabil in my small hp 4 stroke engines around the farm as some have fuel sitting for a long time as it seems to be primarily for that purpose. Seems to work for me.
Everybody has their opinion. I used to be a mechanicing freak and was always tearing into mechanical things just to be doing it. Today I am older, wiser, and lazier, and I let chemicals do the work for me. Their nominal cost is way more that justified by their performance (for me).
I swore I'd never comment on this subject again......so much for swearin'.
