99 xj, 4.0, auto, stock except for modified airbox and Amsoil oil-wetted air filter, Castrol Syntec 10w30, mobil 1 syn in diffs and transfer case. I usually get around 18.5 mpg on my interstate trips and occasionally get up to 21 on secondary highways with approx 55 mph speeds, but while on vacation (interstate driving and a little secondary highway driving with minimal stops) I got 20.9 MPG on the way from Cleveland, TN to Destin, FL and then 22.5 from FL back to TN. I could not beleive it! There was plenty of 75+ MPH driving each way, but had a little less stop and go on the way back from FL. Anyway, I used Marvel Mystery Oil on the trip, both ways and got better fuel mileage on the way down than usual, and my best fuel mileage ever on the way back. I had heard good reports on MMO in the past but wow! Anyway, I know there have been some discussions of MMO on here in the past, but wanted to give MMO a little praise this time. I know the $2.97 I spent on the big bottle of MMO offset the $1.77 - $1.97 per gallon of gas that I had to buy over the 1000 mile round trip, and I didn't even use the whole bottle of MMO. Anwyay, I am impressed. I may not use it around town so much, but I am gonna plan to have plenty of MMO for any trip that I go on. Anyone else on here had good or bad experiences using MMO? FYI I only used it in my fuel at the 4oz per 10 gal recommendation...........Rusty
