I service computers for various state agencies all over the central Texas region, so my commute varies from 0 miles a day to sometimes over 400 miles a day.
Last year I drove 32,655 miles for work all in my 92 ECOdiesel, which just rolled over 400k a few weeks ago.
That's an average of 130.1 miles per working day. I have every fuel receipt and hand calculated every tank by filling to the same spot on the filler neck every time.
Thing is dead nuts right at 42 MPG average over those 32k miles, mostly highways at 70-80.
Lowest tank I've ever recorded in it was 37 MPG (driving into crosswind/headwind with rain for many highway miles) and highest ever was 51 (going slow with a strong tailwind for many highway miles)
I would not hesitate to drive that car anywhere in North or South America tomorrow.
I recently started driving my dad's 2003 Jetta TDI that I rolled over 300k in.
He no longer has his 180 mile round trip commute anymore, so it just wasn't getting driven much. I'm doing all the driving now.
I bought a ScangaugeII for it and that car is amazingly efficient, more than I ever imagined.
Dad would get about 46-47 every tank out of it no matter what, he never knew about the "ventectomy" mod either so would only get about 5-600 mile tanks before having to refuel.
I drive it like a grandpa 55-60 MPH max and am getting 900-950 miles per vented tank (16-16.5 gallons) out of it. That's around 55-60 MPG very consistently.
You just have to have patience and not carry some huge ego on the road when you are driving for maximum MPG's. Mostly flat Texas highway helps as well.
As long as you stay in the right lane on interstates and move over in the shoulder every now and then to let people pass on two laners, everyone's happy.
I've never been honked at or had any sort of aggressive gestures thrown my way just for driving slower than everyone else, it's really not a big deal.
I choose to drive the TDI so slow because it is just easier and more capable of getting those extreme MPG figures.
The key really is the Scangauge, it helps 1000% with knowing how to drive for absolute maximum MPG's. It is scary how accurate it is now that I've run a few tanks through it and got it dialed in.
I get payed tax free income per mile driven, it only makes sense to me to drive a paid off car that gets 40+ MPG's.
Federal rate for 2013 was $0.57 per mile reimbursement. For 2014 it got bumped down a penny to $0.56 per mile.
Last year 42MPG at an average of $3.50/gal was only $0.08 per mile in fuel costs.
This year if I keep the 55-60MPG trend going all year in the 03, I'll only be paying $0.06 per mile in fuel costs.
With these numbers, diesel could be over $20.00 a gallon and it would still be profitable to drive one!
I've been asking some of my friends and random people lately how much a gallon of gas is and about 4 out of 5 of them tell me "Like 4 dollars or something..." They don't have a clue!
Then when I get all cynical and griping about how can they be so oblivious to the world around them, they just say something like "I can't help how much it costs, so why should I pay attention?"
I just facepalm.
It just baffles me how so many people don't even know how much a gallon of gas is! Try asking people yourself, you will be amazed!
Oh but when I mention I drive a diesel car..
ISN'T DIESEL SOOO EXPENSIVE?!? WHY ON EARTH WOULD YOU DRIVE A DIESEL CAR?!?! or THEY MAKE DIESEL CARS?!?! or WHATS DIESEL?!?!
Fools they are...
