Marvel Mystery Oil (MMO) or Seafoam?
I was able to purchase Seafoam up here in the land of the outstretch palm. I put some in the gasoline in my car, motorcycle (1986 Virago XV1000), Stihl backpack blower and my Stihl FS250 trimmer. Both Stihls are 2 cycles engines.
I've been having some starting issues lately with the Stihls. They are several years old, likely over 500 hours on each.
Basically trying to clean-up the fuels systems on each.
If you feel that Seafoam and MMO are pretty much the same results wise, I'll continue to use Seamfoam due to its availability.
Thank you.
