so i took my auto diesel out for a test run to see how it would as far as mpg if i just took it easy. so i went and filled it up to the very top and went and drove it 19.2 miles about half country and half highway, in the country i didn't go above 35 and on the highway i didn't go above 50 a couple spurts of 55 how ever. there was some starting and stopping in the country and a few lights when getting on and off the highway... no real waiting though. so i went and filled up again and actually over flowed it a bit, i put in like a third of a gallon, needless to say i ended up with like 56 some mpg. now i did drive rather slow but honestly 56 mpg with the very low geared automatic, thats crazy. normally i get 35-40, i don't drive slow normally though. i'm gonna try and drive slow during my normal routine for a week or so and then see how my economy is, i figure it will go down some because of warm up time and the amount of time i sit in traffic, but still i got over 56 mpg unless i did something wrong, but i did fill up at the same place and same pump

and to make sure my odometer as right i just checked my path on google maps and it's exactly 9.6, which multiplied by 2 is 19.2. perhaps afterwork tomorrow i will fill up and see then, on the same pump again. work is a much further drive

do you have a tach? what rpm's are you seeing?

wow that's impressive. Definitely keep this updated

That is what I need. As of today, dino diesel in the UK is $8.08 a US gallon, just to cheer you up. Why is diesel tax evasion a national sport over here, I wonder?
Best I've had with the SB engined GTD is 50mpg imperial, so you are doing well. Some rebuilt DNO274's I will be fitting soon, so that should keep some cash away from those that do not deserve it. Keep up the good work!

Sounds great! One word of warning - it's very difficult (i.e. nearly impossible) to get an accurate mileage estimate on that short of a distance. Fill the tank fully, vent it, get it right to the top, run it nearly dry, and fill it again, then calculate your mileage again. With that, it'll be a much more accurate number - and on 500+ miles, a decimal place isn't going to be as significant or anything.

You're certainly not nuts, and it sounds like your car is treating you very well as far as efficiency goes!

yeah this time i had almost 40 miles on my tank because i drove all the way to work and back in normal rush traffic, and i got 58mpg this time it didn't splash at all, how ever i did one of those diesel nuts in a mb td start a diesel convo with me haha. i also had forgotten to reset my tripometer so i had like 36 miles instead of 38 or w/e. next week i will try and go an entire week driving at a steady meager pace like i did the past 2 days i just go 35 everywhere even in 25s and stuff and then i go 50 on the highway, which surprisingly is not all that slow, no body seems to get upset and some people even follow my pace when they could easily pass. so i think after a full week i will get better results. but this is very impressive to me i never thought this car would do much better than 40 because of automatic drive train loss.

well, in my golf i usually see 4.8/4.9L as average :wink:

I think the best mileage calculations are based on several tank fulls since even using the same pump there can be variations in foam etc that may make it fill a bit more or less from time to time. Keep up the good work though! I miss my auto golf

Don't trust the OEM trip meter or odometer, use mapquest or something like that find the mileage of your route.

I did a test of all new hybrid cars and a mk5 tdi a couple years ago for a tv show called driving television. All the cars were brand new, not even 500 miles, and we took all the cars on long drive through the valley, and when we got back to the studio all the trip meters were different by about 3-10km's. And this was only on a 200km trip!

Wow. Impressive.

LWB Joe I will prob be looking at the same for my retirement car soon. If the Sammy runs again I am also looking at WVO soon. I have three shops to give me the grease and it is all good but at 60 MPG I might not have to use it.
