If you don't believe in diesel fuel additives and say they are a waste of money, this thread isn't for you.

I came across this test the other day. It came out in 2007. I'm not the most scientific guy so I'm looking for some input from some of you that are.
The one thing I noticed is that in the Opti Lube test they used double the amount(.5oz/gal)instead of the recommended amount(.25oz/gal)by the manufacturer. Does this mean it doubled the results of this test? In other words, if they used the recommended amount of .25oz/gal would the results have been half as good as reported.

Actually, the test included three different types of Opti Lube, Summer, Winter, and XTD. All three had different Score Ratings, and different mix ratios. Please note below how the Summer Opti Lube compares to the well respected Stanadyne additive in mix ratio, cost, and Score rating.
