Wow!

__. I filled up late last week at 951 on 15.2 gallons (62.6 MPG). (I'm doing my Instrument Rating and I have to drive about 80 each way to the FBO - my instructor is doing "fire patrol" for Weyerheuser Paper and we can't fly until about 4:00 PM so I get to travel during the quiet time of the day -- makes it easy to cruise.) I consider 62+ MPG a "real wow!"

__. I joined the 700 mile club on my 4th tank, the 800 mile club on the next tank after that. I've done a number of 900 mile tanks and one at 1023 miles (and the one last week would easily have gone over 1000 but I was passing the cheapest fuel in the State). I love this car!

700 is a cake walk, 800 is even pretty easy. My best is 1,012 on 16.4 gal. Drove from Seattle, WA to Missoula, MT and back on one tank. [img]/images/graemlins/cool.gif[/img]

763 miles on a tank about a week ago. About 430 miles from Northern New Jersey to Impexfest3 and back, with the rest suburban driving to and from work about 22 miles each way. Took 15.1 gallons yielding 50.5 mpg.

I joined on my last tank. 725 miles on 15.9 gallons of biodiesel (approx. B88) with roughly two thirds highway driving, 44psi cold in the tires and a diesel guzzling PD with 5,500 miles on the clock.

Just rolled over 18K miles, have gotten into the 800 Mile Club once (mostly highway), and the 700 Mile Club perhaps 3-4 times. My driving is split about 40% hwy/60% urban with little or no gridlock: it could be better, but I'm content averaging 43-44mpg! We've been using biodiesel since she was new, and that also impacts mileage a bit. [img]/images/graemlins/crazy.gif[/img]

My average tank is 617 miles(28 fill up's) with 5 over 700 (757 best to date) and I'm making run to 800 now(620 with 1/4 showing on the guage-it's going to be close!) I have filled up 28 times since last July when I bought it...In my old car('88 BMW 325i conv) I would have filled up at least 50 times @ 10 min each time that has saved almost 4 hours and $609 in fuel cost--yes, I Love this experience!

I have done 700 a couple times and 750 a couple times. I am looking to do an 800 tank this summer.

I've been there numerous times now. Friends and family are amazed whenever they see that I have over 700 miles on the tripmeter. [img]/images/graemlins/grin.gif[/img] I'm still dreaming of an 800-mile-tank... [img]/images/graemlins/rolleyes.gif[/img]

Here's a pic of the first time I hit 700 miles. (Almost 10,000 miles ago)

My last well vented tank got me to 720 miles. Thats while doing 80mph and with the AC. I'd love to get more but I just can't keep my right foot from over-pressurizing the right pedal... [img]/images/graemlins/grin.gif[/img]

I've had a couple tanks over 1100, both achieved on deliberately long, boring and slow trips in the southeast.

Flat roads, shorter gears, higher tire pressure, lower oil viscosity, temperate weather, optimized injection quantity, and, above all, very slow speeds (50-60 mph) can all come together to yield approx 70 mpg. 70 mpg yields a 1100 mile tank on approx 16 gallons of fuel, but the low fuel light is on for well over an hour, and that gets a bit nerve racking.

Me! I'm in!!

My lifetime average mileage between fillups is 701.74 miles. The best I've done is 761 miles, and the worst, other than the very first tank from the dealer, is 631 miles. I would love to get to 800 someday, but staring at the "low fuel" light for an hour starts making me nervous. I vent every tank (considering doing the Ventectomy at my 20K service, upcoming shortly) and add 4 oz. of Stanadyne Performance formula at every fillup. My average fill is 14.91 gallons of fuel, plus the 0.0325 gallons of additive. That works out to just over 47 MPG. I've had my 2003 Jetta Wagon for about 13 months, and have over 19,000 miles on it. I've switched to Shell Premium diesel fuel recently, but I cannot say that I see a big difference in mileage from the XtraMart "standard" diesel I used to get. The price is the same on them now where I live ($1.699).

I have the 5-speed manual, and tend to drive "spiritedly," following Pete's (DBW's) shifting advice and occasionally getting over 4K RPM. Like I stole it? Yeah, OK! [img]/images/graemlins/wink.gif[/img] I'm usually the only one in the car, or it's me and my 2-year-old son. Usually long trips (22 miles one way is a short trip to day care, 75 miles one way to work is the norm, and 200 miles one way to a customer has happened a lot). I think the wagon somehow has better aerodynamic efficiency (though it looks like a box) than the sedan, and that shows up in the mileage. I keep my OEM Michelin MXV4+ tires at 38 PSI - best compromise of mileage and ride quality for me. Hope that helps!

The variant is less aerodynamic than the sedan.

Cx for sedan: .30

Cx for variant: .32

There's no variant more aerodynamic than a sedan, foggetaboutit. [img]/images/graemlins/wink.gif[/img]
