higher octane levels??

[blazinmt]

Around here they only carry 91 and I would really like to see what difference it would make with a higher octane. There's no knock or anything, I am just curious.

My friend has a barrel of 114 (he uses it for his sleds) and told me that he threw a gallon of it in when he filled his tank up (he drives a stock s10 blazer with a 4.3) and he said he noticed a pretty good difference in power and an even bigger difference in fuel economy.

Is this a legitimate way to get a higher octane level? Is it safe? What options do I have other than an alky kit?

Yes adding a high octane fuel to existing lower octane fuel will raise octane.

As far as additional performance NO. Unless you were expericencing spark knock with the lower octane. In fact it takes more HP to burn a higher octane fuel!

That being said if the "barrell of 114" was a highly oxgeniated race fuel a significant SOTP gain in HP could happen. Which alot of motorcycle and sled fuels are. But at the risk of going too lean and the resulting burnt pistons & etc. Unless dutifully watching o2 readings!!!:tup:
