On the report it shows Opti lube using twice the recommended amount. Does this double the benefits? Would it be fair to say if I used the recommended amount (half the amount used in the study) that the HFRR would be cut in half also? If so, Opti Lube isn't any better than its competitors.
I am currently using a fuel additive, but not sure its the best choice. Its the XDP Power Plus made by RBP. They're kind of secretive about their product. I think I'm switching to Stanadyne. Opti Lube is a bit on the pricy side, especially if I have to use a double dose.
