Gas differences...

anyone has any idea if E10 Super works with our 3lV6 engines?!?! or will it do a lot of harm....

E10 (10% ethanol content) gasoline is the current standard for most of the U.S. You have probably been using it for years. It is notorious for gumming up carbs in older vehicles and small engines when let sit for periods of time that allow for the degradation of rubber hoses and metal lines other than stainless steel. If that is a problem then use steel and rubber lines as well as filters that are marketed for E85 compatible (marketed as flex fuel) vehicles to limit damage to just your fuel tank and injectors/carb from fuel sitting against the metal and seals. Some people with small engines just run the fuel system dry before shutting them down.

In Florida we have a gas station called "WAWA" and they have blue pumps that are lead and ethel free.  They run about $.25 per gallon more and that's all I put in my TFC' and small motor (weed wacker, edgers, etc.).

I also only use ethanol-free fuel in my TC's and other toys.   I have a hemi 2008 Grand Cherokee that runs fine on unleaded 89 octane, but anything other than ethanol-free gas immediately (within a mile) triggers 3 double obd codes - all related to O2 sensors.  I think some GM vehicles can be reprogrammed to account for ethanol, not sure about Mopars.  If anyone knows how to do this I's appreciate the info.

 

A friend has a small engine repair shop and he says every spring he's bombarded with gummed up mowers and every fall it's gummed up snowblowers.  I'm one of those people who try to run them dry, even with ethanol free fuel.  Cars are a different story as it's just not practical to run them dry and I don't want the gas tank seams to dry out so I use an enzyme-based fuel stabilizer, Startron, as it does not attract moisture.  Here in upstate New York I park my cars in the barn when the salt flies and don't bring them out until we've had at least a couple of heavy rains in the spring meaning they usually sit for at least 5 months.  So far no fuel problems on restarts.
