You want fresh gas? PRI-G, fresh diesel PRI-D
They claim it will actually rejuvenate bad gas. After using PRI-G for many years I found some bad gas (had not been treated) that had the dead gone gasoline varnish smell. I treated it with PRI-G and the smell was gone and the gas ran a small engine just fine.
I have to re-order some now, should have ordered before I posted. you guys will buy it all up now:)
Great tip!
