fuel additives

[redchev20]

I live in Minnesota and we run a 10percent ethanol blend in our gas..i run octane boost and heet.( ethanol draws moisture horrible up here) i was just wondering if anyone has good additives they have found that work well with tbi 350s and ethanol

I found that just good old gas line antifreeze worked well for my truck.

I use 'Lucas' fuel additive. Comes in 3 sizes. I add 1/3 of the middle size bottle (1 quart size) to a full tank. Lucas says that it cushions the valves & adds a bit of octane, but I don't notice a difference unless I add the whole bottle to a tank. The engine seems to run smoother with this stuff. If it works the way that it's claimed to, can't see how it could hurt. I figure that additives like this are usually 'snake-oil', but this stuff really seems to work. Besides, I've seen friends put it into $10,000.00 engines. If they trust this stuff in an engine like that, it must be O.K. Can't see them risking such an investment with just any additive.

Makes sense to me.

I have been trying a few different one and i have found heet seems to work well but no noticeable gain in milage yet....this ethanol blend sucks

They are bumping it up too here. To 15% ethanol

sea foam is the best imo but its not cheap.had a lil car that wouldnt run for nothing the gas we got was so bad once.poured half a bottle in tank and half in the in the engine threw the brake booster got a smoke show. and it ran smooth as it always does.but its not for regular use.. also had good luck with marvel mystery oil but its just a slow cleaner that is supposed to clean slowly over time and keep the valves and stuff lubricated.ran it in a old car and it killed a maf sensor code after a few tanks of gas.alot of mechanics here swear by anythang with lucas on it.i have used it but just as preventive maintence to keep everythang clean

I can still get regular unleaded and super unleaded in Iowa- is that not an option for you guys, apparently? Hopefully they don't change it here-

Word. All I use is Lucas as well and it works great.
