Hi guys,

Sounds like most folks here either use nothing or seldom use anything, I go the other route entirely! Ha Ha. Since I couldn't find any evidence it can do any harm, and I had such good results the first couple times I used it, I now add 5.25 oz. of Lucas at every fill up. Adds 1-2 mpg, keeps the truck idling steady at 699 rpm (I use a digital display with an obd2 scanner), also the truck runs 2db quieter (used an app on my iPhone to test that) and lastly it appears to have a little better acceleration although my 0-60 times (measured by my scanner and Torque Pro app) don't reflect this, it's probably my imagination.
I'd like to point out that when you buy the gallon jug it comes out to only $1.19 per tank, which is about equal to a third a gallon of diesel so it definitely pays for itself. The small bottles at the truck stop are usually about $4 for the 5.25 oz.
1 gal = 128 oz which is 24 of the little bottles.
