My problem is that it seems to hard enough to get 93 octane here in town and when you're out on the road you need a fix bad man. With this stuff, you load up a couple or more bottles and when you run low on gas, you load up with this red kool aid lookin stuff and load the tank. I've never mised it as strong as the village smitty and compression should be real close to his. I have used up to 2 oz per gallon of 91 octane.
