Title: fuel type, plug fouling
Post by Engine_Outlaw on 06/16/06 at 08:02:47

I put highest grade premium gasoline in bike, mechanic's advice, but recently fouled plug. Is this a no no.

Use regular gas.
Only use choke if it won't start without it.

It's a low compression engine - there's no need to run high test. It will actually run and perform better using regular. If it's really hot...maybe run mid grade.

You're just wasting your $$$ running high test.

Only time I ran a higher octane is when the bike was sitting for a bit and I ASSUME this helped burn junk out... but I could be wrong.

Higher octane rating is, I think, a measure of resistance to predetonation. Savages don't have the compression to need higher ratings. I am not sure about those wild Texas 120 degree days, that might argue for a step up.

I think high test has more detergent. I used to run a tank of high test in my van once in a while before the prices went crazy to help keep the injectors clean.

The detergent in the high test probably helped get rid of the varnish that had accumulated in your carb.

No need to run high test in a Savage for the octane.

That is correct. The only reason I use mid-grade (89 octane) is because of the high temps in our Texas summers. In cooler seasons I just use regular unleaded at 87 octane.
