hello guys! I'm wondering how many brands of oil have stablizer in them? the Lawnboy ashless does,, but I've got 3 bottles of Klotz RC model lube synthetic,, and some amsoil,, do they have it? the Klotz web site doesn't say,, and is the stablizer important? I had been running 100 octane av gas for years,, but my son is trying to talk me out of running it,, says it's not worth it,,(??),, I wouldn't be above buying a stabilizer additive,, auto gas just doesn't last,, like av gas does,,(3 years from what I hear) opnions? thanks!
