I just started using Drews mix. My last trip with 5th wheel rv was getting 12.5 mpg on the tank I checked with load. This was about 1.5 mpg better than pre mix. Haven't had an oppurtunity to check a full tank unloaded yet. Was getting a little over 17mpg, in town, unloaded before using mix. Think I may be having lift pump problems so will be going to dealer this week.

Drew, mine's, 2005 CTD Quad Cab is pretty stock with the exception of my tires 305's, but my overhead which deosn't apper to be any different than my speedo, says 14.7. Now like I said with the bigger tires i haven't had the chance to takeit in and get the speedo calibrated for those tires! Does this add miles quicker or slower with the bigger tires?

 

ooops didn't read the info, 2005 ctd quad, 4-11's, run 16oz power servce with the 8oz of marvels mo, 305 tires, other than that stock....14-15mpg.

 

04 3500 QC SRW 4X4, automatic, 4.10's, 305/70/17 maxxis buckshot mudders. i have an aFe filter kit, and run the power service (grey bottle)/mmo mixture as recommended on this site. before the bigger tires i was getting 17.2 hwy and 15.5 city. put the tires on and it went down to 14.9 hwy and 13.3 city. once i started using the ps/mmo, my mileage is back up to 17.1 hwy and 14.9 city. i cant believe how much the ps/mmo helped! i am glad i found this site and it is nice to "chat" with people who know what they are talking about.

 

sorry I havent gotten back to you on this but you will be adding the miles quicker than what the speedo says.

lets say your doing 60mph. with your 305's you might have about a 10% offset on your speedo so that means you are actualy doing 66mph.
