Bad MPG. Bad fuel?

[sjl2725]

Any of you guys (and girls) ever get abnormal mileage from a tank of fuel?? I know we have the winter additives now, but I filled up the other day, and I am at 30% remaining, and have only gone about 120 miles. That's really bad. Still driving the same roads as I always do. usually I'm around 200 miles at 50% with my normal commute, 35 to 45mph...

I filled up at a different station this time cuz it was a little cheaper. Could I have gotten a bad tank of diesel? What constitutes as "bad fuel"?

My wife is going to be pi$$ed when I tell her I need money to fill up again!

Man, funny you post this. I just got a tank of gas on a 800+ mile trip and got horrible mileage. Next tank of gas got my normal. It was so bad I took the truck in to have it looked at to make sure all was good. I chalked it up to that partiular tank of gas. All has been fine since.

I would stop putting gas in a diesel truck first :

On a serious note though, I noticed a few bad tanks mileage wise on a trip to TN. I remembered wondering if it was bad fuel or winter blend since I was farther north. I don't think we even get winter blend fuel down where I live.

Never sure if it is worth adding cetane boost for the $. Any thoughts??

I was kind of wondering that too... sort of waiting for one of the pros to chime in!

I was in Clarksville, TN when I got the DIESEL that I got horrible mileage on.

I am sure that TN has winter fuel now. Here in north GA we have winter fuel.

opinions on cetane booster? Yea or nay? Pros and cons?

It's definitely better for your engine. The ULSD that we're running now lacks the lubrication of past fuels so running it will only lengthen the life of your engine. As for MPG gains...well they're supposed to but I don't really see much difference when I run it. I've been out for a while though and just ordered a gallon with my filters so I'll be running it again next week. If I notice a difference I'll post up.
