I have noticed that alot of guys use Chevron Techron. I read today that it is not recommended for two cylinder air cooled engines. I have used Lucas fuel treatment before after I saw several cars pass the smog test in TX after running a tank with Lucas.

 

HD makes a good a good fuel additive for $4.95 that treats up to 40 gallons. When you use it you will feel a definite power increase. I have been using it for 8 years and really like it. I dont use it every tank full. Once every 3-4 tankfulls.

 

I use gasoline.

Don't know if additives do any harm or good. Do a search here on Top Tier gasolines for further info. Some Top Tier stuff here:

I have used Lucas fuel treatment in my Fatty- appeared to help a wee bit.

Unrelated to that though, i hear it takes a few tanks of good fuel to to get sta-bil out of the fuel system; bike runs like crap with that in it.

 

Fuel additive and fuel system cleaners are two differant things. Additives try to increase performance in one way or another. If they are effective, then they only work while you're burning fuel with that additive.

System cleaners have a differant goal. During use, fuel leaves junk behind: varnish mostly, but other stuff as well. A cleaner attempts to dissolve that junk, and push it through the system to be burned in the comubstion chamber.

About twice a year I add a little cleaner to all my vehicles. I use either Techron, or B-12 Chemtool. I used TEchron for carbed vehicles in my '97 WG. It was still running good in 2005 at 45K miles without a carb cleaning or rebuild. I guess it worked. I've used it in my V-8 EFI truck once or twice a year, too. At 97K miles and 7 years, it's still running good and idling smoothly. I guess it worked there, too.

 

I like SeaFoam. Good fuel system cleaner that's been around a long time (1930's), never had any problems with it. I put it in the tank every 3months or so.

 

Ditto for Seafoam.
