For those interested I have went to 25 oz.'s to a gallon of fuel of the Klotz with good results. I have the Extreme which is 50% stronger over the Klotz but I like the cooling affect of the Koolinal in the Klotz. I've finally got the jetting right for this much additive and will be running 10oz.'s of Extreme and 10oz.'s Klotz Nitro that way I get the benefit of the Koolinal and the most power benefit out of the stronger additive; the Extreme. I just received some more Extreme today and will be going to the mixture of both over the weekend. I'll let everyone know what I think of the mixture compared to just running the Klotz. Slim
