I don't feel so bad now....only got 37.8 on my last tank(80-ish mph indicated)....down from a 41 average when it was cooler. I too will gladly give up 3 mpg in this heat....black car + deep south= HOT...but I still love the color choice.fish_on said:56k on my 05.5 and my mileage has been down slightly the last 2 weeks (6 tanks of fuel) 49mpg to 42mpg. I have been running the a/c more but it seems to be a pretty big drop.
Just completed a 700 mile trip which began with ~1/2 tank (refuel necessary) ... unintentionally got the ULSD during the refuel. Indicated mileage has dropped from ~48 mpg to ~41. Have yet to verify w/ calculator (even @ 41 mpg, have yet to burn it out)robrichtx said:I will double check. My wife works in the Petroleum Industry and will be able to source this out with the major carriers.
I really hope you're wrong Quartermeter - for all the right reasons! Unfortunately, I am afraid that you are either right, or a bunch of us are losing mpgs for no apparent reason.
You know, I love being able to kick out black smoke for tailgaters. I have never been able to do that beforeFrank M said:Recently I had a tankful that seemed to give me a little less power. I could barely muster up black smoke for tailgaters and my mileage was down about 7%. I had a feeling it was ULSD but can not prove it.
Oh yes I agree completely. Almost daily I find myself driving in the rightmost lane of a highway going 5 to 10 MPH above the speed limit when another car comes up behind me. They tailgate, they flash their high beam headlights, they sometimes wave their hands around and have angry facial expressions. Hey, I'm in the rightmost lane already speeding a bit - they should pass mein one of the other lanes to our left! Well, often in these cases I downshift and floor the accelerator. A nice dark cloud shoots out the exhaust tips. I'm sure that cloud of diesel exhaust smells really good (heavy sarcasm)...! Note: we can't do this often because it takes a bit of driving to build up some nice soot particles.Highline said:You know, I love being able to kick out black smoke for tailgaters.

Should have been about 25 MPG at top speed.LILALLEYKATT said:I just did a top end run in southern Tennessee and pulled 124M.P.H. on the speedo. My Garmin gps indicated 119M.P.H.. I thought Jettas were sopposed to be governed to 114M.P.H.. I feel like my Jetta is worth 125M.P.H. actual because it was still pulling when I backed off..Oh yeah I was getting 10Mpg...LILALLEYKATT

In my book you get a big A+ for effort!Frank M said:I had my 1200cc 40hp 1965 Beetle out the other day.
I met a Ferrari Testarossa and he wanted to go.
I quit at 58 because I could not see him any more.
Still depends on the length of your trips. With short trips not only do you have to heat up a cold engine, but you have to chill a blazing hot interior every time you start the car back up.buckeye96 said:I keep my AC on 74 all the time so wouldn't my mpg be better? Cause I am still seeing a huge hit in efficiency
Just to add my experience: I was averaging about 42 mpg (4000 miles). The lowest I had seen was 38. This past week, my mileage dropped to 33, but not with any change in my driving style or conditions. I use Stanadyne with every tank. Ugh.two.marek said:My MPG get down too.
I think the fuel is the main problem.
I have overheard about intentional lowering diesel fuel quality in order to keep gasoline prices down.
Any one can explain to me why diesel fuel is so expensive compeer to gasoline?
Any way, A/C is the factor, but in the past I did not see so dramatic changes.
