Read world testing of Opti-Lube Additives on Fuel Mileage
 

I would like to let people see and watch this as it unfolds. A person who we do not know has taken it upon himself to do some testing of our additives and what effect they have on mileage on his TDI. Its a pretty interesting read.

The results so far are in post 3. He is in his second run trying to duplicate the results.

Nice post. Really liked the info there..

Just cause it works in a little VW doesn't mean it'll have the same effect in my F450 pulling trailers from Indiana to Texas and often a trailer back that way. The TDI is a great little motor. but not exactly the same as a 6.7Power Stroke. I sure wish I could get that kind of mileage though. :jump:
