Default I can run 89 octane

For a13,000 milesI have put 93 octane in my 1200 Custom cause the owners manaul says 91 and I can't find 91.

Last week I converted to 89 octane. 2 fillups later there is no problems with dieseling, or anything else different. I have my fingers crossed.

Any ideas what problems it might cause? I have not check the plugs for signs of pre-detonation, but I know it is not dieseling.

+1 What are you saving, 40 cents per tank fill? Subtle spark knock can be hard to decern over the typically noisy (normal) top end clatter and its effects on the motor are not pretty..

Wow I just did the math, I was so hoping to save some money. It is a savings of about $15 a year for me.

Guess it is back to 93 for me.

It was just the thoughts of saving money when they want an arm and a leg for gas. I gave it a try swearing I would save a mini-fortune. Funny how little it will add up over time, between $15 and $25 a year is all. I guess trying to save a few cents here and there on gas doesn't make sence when your getting 45 MPG.

I didn't do the math up front. Sure seemed like a lot more money standing at the pump looking at prices.

I don't need anymore chrome nuts.
