Also i kinda cringed when you mentioned you put premium gas in your tank. Premium doesnt mean the gas is better, it simply means that the fuel ignites at a different stage than other grades. This comes into play with higher performance engines. 87 octane ignights under a certain compression at a certain temperature when your pistons are at a certain point in the cylinder. Putting a different octane in your engine changes when the fuel actually ignites. Your engine is set by the factory/computer to ignite the fuel at a certain point. So either its ignighting sooner or later with premium and best case scenario your computer will adjust and compensate. either case you are throwing money away. Heres a thread I found on a CR-Z forum for you.

real quick heres another article on the premium in regular tank

I guess I have never heard that using a higher octance fuel (in the range we are talking about) would hurt a vehicle in the slightest. I thought even on a vehicle that say 87 that it said 87 or higher or on a vehicle that requires 91 that is says 91 or higher. I will have to check around more later but in a quick search, I could find nothing that suggested putting premium in his CR-Z is going to cause any trouble.

Now to the other note, about wasting his mone. I disagree with this. My wife has a 2004 Civic with about 107,000 miles. About 2 years ago, the price was within 5-10 cents for unlead/premium so we decided to put premium in that day since I always am putting premium in my car. And since then, as long as the premium price isn't over 10% greater than unleaded, we run premium in it. Since switching the car over to premium we have seen 8-11% better fuel economy on average. And no, I am not basing this on a couple tanks of fuel, every tank of fuel that we have put in that car in the last 87,000 (bought used) has been recorded.
 
The "minimum" octane is 87 for my car, so using 93 isn't going to hurt the car one bit. I ran premium in my 2010 Fit and the winter mileage went up from 22-23 mixed driving to 28-29 using premium, from that day I was sold. If you think about it, the computer detects better fuel and adjusts things accordingly, so the added mileage should be from a slight increase in torque, which I did start to feel after a while in the Fit, not to mention I added an intake some time after that, so ofcoarse the computer would once again adjust to that as well.

Its about .30 more a gallon here, so if I were to run the tank all the way down, the extra cost would be $3.00, no biggie IMO.

Will, thanks for the compliment on my car and good luck with that name for your company!

Haha thanks, I've got everyone in the office helping me brainstorm.

Interesting comment on the 93 octane, I'll have to try it on a fill up and see what happens
 
Hey Will, if you do run premium you've gotta give it a couple tanks to see the difference for sure. The other thing is this, I use the "old school" method of checking mileage too, not just the OBC, so keep this in mind.

Good luck with your brainstorming sessions too. Just for the record and maybe this will spark something for you, when I used to do cars on the side when I had a house and could really commit to it whenever I wanted to, I had business cards made up, check this name out. "Purrrr-fection Auto Detailing"...."your car will be the cat's meow!" I'm more of cat person for sure, this is why and how I came up with the name and tag line, hopefully this helps you out some:xyxthumbs:
