Not sure, but does ethanol blended fuel make your bike run hotter ? And if you can't run any other type of fuel, do you add octane booster even though your already running the 91 octane ?
What year was the venture? I understand Chevy made significant modifications in more recent years to prevent the types of problems I had with the 1998 model.FWIW, I have run my Venture for 40K plus miles on regular 10% ethanol. No gunk in carbs or other badness to report.
but they do not make premium regular gas - and my engine specifies premium - now what?The above information is spot on. I am a small engine mechanic and deal with customers that purchase the cheapest fuel they can get. Here is the point...We own 20k+ motorcycles, so trying to save a couple of dollars on a tank of fuel is, to say the least counterproductive. If you can obtain 100% fuel...do so. If not there are many fuel additives on the market, (do your research) that can be helpful. Ethanol used in air cooled engines is NOT a good idea...it is however good for business if you are a mechanic...'nuff said?
All you can find in most of Texas is the "Iowa Welfare Gas." It plays Hell with my Vespas. It seem like I am replacing the fuel lines constantly and they can't sit more than a few days without crap in the carbs.I put Seafoam in every tank to keep them running.Get the regular non ethanol gas and add octane booster.
I believe this to be a little high....the first gallon to gallon and a half that you pump will be the fuel that is left in the hose from the guy before you. ...
Wow, I didn't know this was such a problem.I believe this to be a little high.
I have been looking around the inter-web and the general consensus seems top be 10 oz give or take.
although too little octane results in pinging, another concern is that much octane does your engine (and pocketbook) a disservice
I would be more concerned about avoiding ethanol blends when ever possible.
