Gas Change this Early??

Frank Hudon · 02-25-2006, 10:28 PM

as a quick check you might want to google SAE OBD11 protocals and see what comes up. It'll be in the SAE's web site somewhere as they are the ones in charge of the specifications for it.

All I could discern is that I had to anti up to get "in". I am not sure that the information is worth the investment for me.

That's the problem. I see no reason to hand someone money for a
little understanding of packet formats, that should just be out
there on the net anyways given how many people have implemented
them. Just like tcp/ip and ethernet framing and PPP and all that.
This whole deal with spending hundreds of dollars on copies of an
"international standard" is a complete scam, and is probably
responsible for numerous poor/incomplete implementations.

Amen "international standards" should be available at a more reasonable price. I would not object to a minimal fee or even a moderate fee but this is a bit over the top for a download. The printed material is another story, but bits and bytes?

Back to the subject of gas...

A couple of days ago I filled my tank, and then decided to try driving according to all the high-mileage gurus, particularly after reading a post somewhere from a two-Prius household with a 10-mpg difference between the featherfoot and the leadfoot. I had already put 3 or 4 miles on because of a trip to the grocery store, but I've now got 75 miles on this tank, consisting of two trips to church (a supper last night, and services this morning).

The computer says 52.5 mpg. This is city driving because I take the surface street (for the better mileage, the shorter route, and the bone-shaking cobblestone-like condition of the freeway). Temps have been in the 20 to 40 range. Speed limit is mostly 35 mph, with some 25 and some 45. I've been using a feather foot, plus judicious use of EV (those annoying times when speed is slow, SOC is high, but the car is slow to shut off the engine. Especially on a stretch through downtown, followed by a long downhill to the river crossing.) Cabin heat set to 72 degrees and fan on low.

Okay, 52.5 would be average to mediocre for Dave. But 48 is the best I've ever seen on my MFD before, not counting times when I filled up and drove the 3 blocks home on EV, back in Fargo. Summer gas may be a factor, if they've switched now, as this thread's title speculates, But I think I've improved 5 mpg just by driving like a little old lady.

I don't know if I can keep it up, though I'll try for this tank, just to see what happens when the short trips are factored in.

WTG daniel!! glad to see you are getting the great mileage... but you have to realize the 40º difference between Spokane and Fargo has a lot to do with that also.

daniel · 02-27-2006, 11:16 AM

Yeah, but this is 5 mpg better than I got in Fargo in summer on my best tanks, when there was a good mix of some longer trips (to the shopping district.) So the difference is the Zen driving. Not sure I can keep it up, though.

It'll be fun to see what happens when it warms up here. It may be 40 degrees warmer than Fargo, but it's still 40 degrees colder than summer.
