...besides cost?

Was going to put some in my turbo and was told it might ruin my afr meter...

True?

Does it go bad faster than regular gas?

Less cleaners in it?

How long does it stay good for? Months? Years?

Gas station by the track had 100 and 110. Almost the same cost...

Why wouldn't you get the 110?

Thanks...

Why do you want to use it?

higher octane is going to be more knock resistant so you could tune for that with more advance or more boost etc etc. If you are tuned for 93 then not much benefit.

Leaded fuel will ruin your O2 sensors, ie 110

It depends if it is leaded or unleaded race fuel. Leaded ruins O2 sensors. Race fuel can also have different flame front speeds which affects how it burns. Read the VP page and you'll see all the different types.

Race car or street car? If street car, your only benefit will be a lighter wallet.

CAN YOU OVER OCTANE AN ENGINE? IF SO, WHAT HAPPENS?

Yes you can over octane an engine. Generally you will get sluggish throttle response. Also you may get fouled plugs and deposits in the exhaust ports and headers. When an engine is trying to burn a fuel that has too much octane, the burn rate is incorrect and all of the fuel won’t be used up. This excess usually gets left as a deposit or gets pushed out the exhaust. It is important to match your engine’s needs with the correct fuel.

BESIDES OCTANE, WHAT ELSE DO I NEED TO CONSIDER WHEN SELECTING A FUEL ?

Too often, racers focus only on octane when evaluating the quality of a fuel. Octane is certainly important, but it’s just one of several key fuel properties that should be considered when evaluating and selecting a fuel. It’s entirely possible to generate more horsepower with a lower octane fuel if it’s designed properly with respect to its other key properties. It’s also possible for two fuels to have the same octane rating, but perform very differently due to their other key properties.

Hmmm...

Car is a 930...

Figured extra octane may provide a safety buffer from detonation...

Running 0.8 bar, previous owner ran 1.2 as far as I can tell...

Figured putting in 5 gallons of the 110 would give a bigger safety margin on the track...

Gas station have it for $7.50. At the track it's $10...

As stated above, you can get some detonation resistance. For a turbo with boost cranked up or at the track, this can make sense. I'm not sure if a 930 has a cat, but don't put leaded in if you have a cat.

I would bet that one doesn't
