A new station that went in up the street from me has 100 octane gas. I think there was a thread about six months ago regarding higher octane gas. Does anyone use this in their Type S? If so, what differences were experienced? This stuff is going for $3.99/gallon, and I considered just adding about four gallons mixed with 93 octane. That would give me a total octane of around 94.8. Adding another two gallons of 100 octane would make it about 95.8, assuming that gas mixes to conformity, which I'm not sure about.

Any suggestions or experience with this?

Thanks

 

We have been over this topic before many times on the TL board.Someone posted the same question last week on it. Acura sent me an E-mail a few weeks ago. It was a Tech Tip it said your car is designed to run on 91 Octane. The Tech Tip also siad using anything higher is wasting money. Somepeople such as myself can't find 91 so the average premium octane is 93 in this area. Sunoco is 94 Octane but that is premium for that brand & cost a few cents more.So with this said nothing special for us using anything higher than 91 Octane. We don't drive Nash Bridges 70s Cudas or GTOs from that era. I was just looking at one of my old copies of Road & Track. They have a 2001 Lamborghini Diablo 6.0 pictured on the front page. In its specs for this 550HP car the fuel needed is premium unleaded 91pump octane.

 

the point of higher octane gas is just to resist engine knock...which is when gas combusts for compression and not the spark...it brakes your engine...there is no way our engines will make enough compression stock to have the octane of the gas matter. So no dont waste your money.

 

It may be the different make up of the 100 octane gas vs. the pathetic California gas we get, but I've done a bunch of comparisons and got more punch with the 100 octane.

The extra "punch" could be from the gas formulation in lieu of the higher octane -- who knows.

If you want to figure it out for yourself, just try some runs on the same street with the temp and gas load (and other factors) being equal. After a number of runs, you should be able to come to a conclusion...

A stock compression CL-S shouldn't need any higher octane than 93 on it's worst day. 100 Octane Racing gasoline is designed for higher compression machines than these. Show me the Dyno sheet before and after for me to be convinced. I would say your wasting your money.

 

buddy, this is 7 years old.. discussion ended already.
