I've never believed much in this stuff whether it was for a motorcycle or snowmobile. Never even thought about it for cars. With the so called possible shortage this weekend, I am wondering about possibly premium maybe being harder to find on the road. I had the Ford tune upgrade installed several years ago, and it requires 91 octane. Any proven tested booster's to use with 87? Looking for proof, not just " I've used brand XYZ for years".

 

When I was racing I bought aviation gas very high octane mixes easy with your gas. I don't think there is lead in it

 

Not practical when on the road state to state

 

Looking into "octane boosters", I found they all relied on the use of ALCOHOL to raise octane rating. (The octane rating of pure ETHANOL is 113). However, loading up on alcohol may not be such a great idea, as unless designed for it, most fuel systems react adversely to the solvent effects of alcohol not found with gasoline. Others are usable: Benzene, 115; Toluene, 121; Isopropanol 118 (Propyl Alcohol), etc.

 

I am having success with several choices of Premium no ethanol selections at the pump...93 octane and no ethanol.
