Try Berrymans B12.. You can get it at Wal Mart..Iv used it for years and it works great even in two strokers.. <br /><br />And I know some of you will disagree...about putting into two strokes..But I and alot of my customers will agree with me!<br /><br />We even inject fuel into the crankcase of four stroke engines in COLD weather climates to thin the oil so we can start some aircraft engines (approved by manufactures)
