Let me first say I have never used any mystery oil, seafoam, MIB...
I have a 20 year old Craftsman riding mower that has been used, some may think even abused, on my very hilly 5.5 acres. The past couple years it has been running rough despite new plugs, air filter and fuel filter. Out of curiosity I decided to try MIB. After running about 5+ gals of gas through it with MIB the past two weeks the tractor is definitely running a lot better, maybe even almost perfect. And only for $5. lol
This is a definite ymmv
