Anyone ever fill up their VX with 100 octane gas?
Just curious because there is a station here that sells racing fuel (100 octane at $7.65 per gallon) and I was just thinking it would be an interesting experiment with the VX. I personally notice a difference in "pick-up" when I use premium over regular, so it just got me thinking, what would 100 octane do?

Doesn't it run hotter & risk burning a valve or ring?

OK, looks like I was wrong ... but without the higher compression to take advantage of the higher octane rating, there are no benefits.
Super VXer
Well, that's kinda what I was wondering, like, would it do any harm or not...
This was really nothing more than a curiosity, I thought maybe some of the S/Ced VXers out there have maybe tried the high octane stuff.

For a whole lot less you can drop a bottle of 104+ octane boost in ypur regular unleaded.Originally Posted by nfpgasmask

Yeah, like I said, this was nothing more than a curiosity. I've always heard people say that premium shouldn't make a difference in out VXes but...

bart i use premium in my VX always...
the way i figure it, for the extra 2 or 3 dollars a tank, i get better mileage (i have measured it), i get better perceived performance... and it cant be bad for the motor

I don't know exactly what gas you were looking at, but I have been involved in motorcycle racing for years. Bikes have very hi compression engines by comparison, usually 11-13:1. I know most racers, the first thing after a race drain the race gas out of their tanks & system, then fill it with pump gas. I don't know how true it is, but I've always heard race gas is VERY corrosive to the fuel system. Just my observation and 2 cents.
Super VXer
It is very likely to be corrosive. Just open that link to wikipedia & see the stuff they add to boost the octane rating.
The only thing worse would be to add acetone - sorry wrong thread.

My car has 12:1 compression, yet there is no performance gain from gas above 93 octane . The ecu is not programed too adjust to anything higher . I have yet to get any engine knock from 93 octane .
The VX always gets 87 octane . Now if it was super charged I would definitely try higher octane gas.
Super VXer
You absolutely right !
I also use premium in my horse + drop twice a month a fuel booster in the tank & all i can say is way better,better acceleration,better MPG,better performance & helps maintain your fuel lines much more cleaner.
In regards of the 100 octane fuel i'll 1rst try with 1/2 tank,hit the highway with the tach ready to provide me results after the run
Dakar was just the begining.

A bottle of the 104 Octane mixed with a full tank of 89 octane fuel might give you 89.1 octane. Don't waste your money. I tried it in my Hot Rod days and it's worthless. I ended up using Cam2 (110 octane) and Turbo Blue (105 octane and cheaper then Cam2) back in the late 80's early 90's 2 stations in town had them in the ground during the summer months. But during my longer road trips to shows I ran a mixture of Premium unleaded and Regular Leaded (yes when it was still around) and it wasn't bad. I wasn't going to waste Cam2/Turbo Blue on the interstate. But I know the higher octane (above 100) brought my Blown Big Block to life and it ran 10 to 15 degree's cooler...For a whole lot less you can drop a bottle of 104+ octane boost in ypur regular unleaded.
Gasmask...Try about 2 or 3 gallons of it per tank full. I bet you'll you'll notice a difference

not worth the expense.

All depens though.
For instans here in NYC the regular fuel is 2.79 & premium is 2.99 which is only 20 cents more.
If you do the maths is only $ 4,50 extra for the premium.
When i used the regular fuel i was getting 'bout 16 MPG but with premium my horse is recording 22 MPG (highway) which is 6 more miles.
Of course traffic conditions & drivings manners apply
