This will sound like a bitch session, but it isn't. I am hoping someone actually knows the answer to this question: how come gas prices keep plummeting, but 100 octane still costs me $6 a gallon?

Could it be that they don't make much of it, so it isn't as directly tied to supply and demand...or do they just know I am a sucker? I could go back to premium and octane boost, but my car doesn't run as well.

Here in Reno at VP Racing, 100 Octane historically had two prices $4.99 and $5.99, I'm quite glad to see it at $5.99 once again as it was up around $8.

The best you'll get out of most octane boosters is about half to one point, which is generally a waste of money as your engine will never know the difference.

What is your engine running that you need 100 Octane? Maybe detune it a little and make it more street friendly? Consider buying a 55 gallon drum of 100 octane direct from VP to bring the price down if you have to use it all the time.

Detune it? Uhhhhhh, That doesn't sound fun. :-)

I don't have the build sheet on the motor, but the motor doesn't run as well if I use normal gas. And it diesels when I shut it off, which is embarrassing.

I used to think 55 gallons was a lot to buy at once, but I can go through a 22 gallon tank of fuel pretty quickly if I am going on runs during the weekends. 8.5mpg doesn't get me very far.

If it would work,depending on what type of ignition system you're running, have you considered putting in something like the MSD adjustable timing control? I was having some pinging problems with my engine after a rebuild a few years ago unless I mixed some 110 octane race gas with the 91 pump premium. After I installed the adj. timing control I can dial in the necessary retard on the fly whenever I start to get pinging on straight 91 octane. Works great when there is no 110 race gas where ever you happen to be. I really can't notice much change in performance and the car doesn't diesel when I turn it off when it's retarded a few degrees with the control. If I later throw in a little 110 I can just dial my advance back up. To answer your original question about price on higher octane fuel, my supplier of the 110 octane pays the going price when he fills up his tank & that will last him 2-3 months depending on the time of year it's purchased. I expect his next load will be cheaper than what he has in the tank today because he had to fill up when gas prices were high. Hopefully, the next load will reflect the lowering in gas prices. FWIW.

I will look into the variable timing, that is a great idea. I don't need all this power all the time.

Your answer about gas prices makes perfect sense. I thought it was something like that, but I never thought about the fact that they don't buy it as often. There can't be many people buying it, especially now.
