Ok thanks guys. Looks like ill be running 87 from now on.

I heard running a tank of E85 will help keep the fuel system clean. I think its 110 octane

If you want a clean fuel system, run a can of Sea Foam through it. Forget the E85. Yes, it's high octane, but I've never heard it referred to as clean burning, let alone a good cleaner.

I can't tell any difference in mine.

I use the 89 simply because I almost exclusively use Esso fuel and the 87 has alcohol in it, the 89 does not. The extra cost is made up by the extra mileage I get on the alcohol free fuel.

In Iowa the 89 has 10% Ethanol

He's probably referring to ethanol being such a good solvent. The reason you'll see 'hiccups' when you convert an old engine over to even 10% ethanol. This is talking point #6 for the ethanol haters!

 

Nothing to do with octane rating, though.
