Adding cetane will give you another 4 mpg.......

First tank 35mpg in town driving. Not too bad for a new engine and metro driving.
Try adding cetane booster.
I geeked my cetane up on the way to TS Friday [just dumped what was left in the tank]. I climbed Monteagle at 2100 rpms and the idiot display said 31. It zero out on the descent [over 199 mpg
]. Over all the idiot display said 42 on the way up with the cruise set at 9-11 over.
On the way back that tank was all but gone by the time I reached Nashville along with the cetane. I filled it 1/2 way up due to the price and got 35.5 on the way home running between 80-107.
I topped the tank off this AM then ran a known 125 mile trip and got 36 so the moral is cetane raised mpg by 4-6 because I had been getting 36-37 on the big road lately and Friday was the first time in a long time I added cetane.
I bought a bottle on the way home this AM and I'm going to see exactly how much cetane it takes to get 41 vs 36.
My car normally smokes a little at WOT but it didn't Saturday as a result of the cetane acting as a catalyst with the #2. I noticed it was smoking last night after I added fuel in Nashville so I know more of the fuel is burned
getting by exhaust in the mirror and the idiot mpg gauge.
