Stabil
Another satisfied Stabil user here. Used it for years in bikes, cars, mowers, lawn equipment and have seen no ill effects.
TIP: If you have a vehicle that has been sitting up for a long, long time try some Marvel Mystery oil in the gas (Bardhal and 2 stroke oil works too) for the 1st thankful of gas. It helps free up the rings and gets things sealed again. Just had the experience in my 1963 E-Type Jag. It had sat up for several years and we decided to take it on a vintage rally. 4 days, 1,100 miles at a very fast pace through the NC mountains. Used lots of oil for the 1st day - and after a dose of "mystery oil" sealed itself to use only 1/2 quart in the last 600 miles. BTW - 92,000 miles on an all original motor that has never been opened.
