I'm going to try higher doses of Redline myself. My mechanic adds a full bottle of 85+ at every oil change, and my tank was below a quarter tank when it went in. When I filled up, I took about 19.5 gallons, and I added about 3 oz of Redline DFC. I notice improved throttle response, and the engine seems to run quieter. I'm going to experiment between a third and a half bottle of DFC at each fillup, or tripling the 1 oz/10 gallon ratio. I'll keep you guys posted on what I notice. Of course, diesel fuel varies a lot by region.
