Lean stock LS650 alternate solution?
10/01/06 at 11:10:50

What do you think about adding up to a quart of diesel fuel to the tank every fill-up, make the engine run on about 10-15% diesel fuel? This would provide lubrication to the top end and give you a little "thicker" fuel mixture which requires more O2. Thoughts?

The reason I was thinking about this is I had a coworker accidently fill his tank with diesel, thing was it was a chevy 350 gas engine. (This happened about 20 years ago.) It ran terribly, so every 30-50 miles he'd stop and top off with gas. After about 300 miles of this, he said his truck started getting "great" gas milage and ran better. I seem to remember him mentioning that his truck came from a higher altitude and was set too lean...

How does adding diesel fuel to a gas engine accomplish anything except destroying a gas engine?? I think your friend was covering up his screw up. The lean engine has been covered, try a search. The secret to curing the lean condition is in the carb, air intake/exhaust and spark. honor the trilogy and do a search. Its easy with simple hand tools.

I wasn't suggestion this was a better solution than running the bike at stoiciometric ratios or below. But the terms "lean" and "rich" only indicate the fuel to air ratio in relation to the idea stoiciometric ratio. Changing the mixture OR the fuel, OR several other factors will change said ratio.

Just trying to start an interesting discussion, but it seems to have backfired. (Pun intended Grin

perhaps not much different than running some marvel mystery oil in the fuel. i burn my left over two stroke fuel from my ski boat, through which ever vehicle needs gas at the time, doesn't seem to hurt anything. i suppose in moderation, it may cool the fuel, and help resist pinging too. one of my dad's friends races two stroke go-carts, was fighting a lean condition, added more oil and got leaner, as there was less gas to mix with air, and oil doesn't burn at the same rate. thinking outside the box is not a bad thing.

I've seen it, read the bottle, tried to figure out why it's red. Tried to figure out why they say you can put in in your gas OR your oil.

It sounds a little too much like snake oil to me, "cures everything from warts to toothache, Buy a bottle now."

Is it oil? Does it burn? Will it really work like diesel fuel... *maybe I shouldn't have poured a little into my tank thinking it would help clean out a carburator that hadn't been used enough lately Embarrassed
