Well today concluded my best tank of gas I've ever gotten! 322miles on a full tank, I did not chance running out so i drove into the gas station with the needle resting on the little stop pin on E. I was very impressed, I had notused the kick down on my last 2 fill ups and car must have learnt that and adjusted for economy...lol

 

Nope it isnt, ive had that amount many times. when i used to drive up north 170 miles i got 41mpg and 322 per tank that was only using a quarter highway and 3/4 city. Quite amazing for an auto. but when i approach long hills i put it in neutral and coast for a long ways, saves quite a bit of gas on long trips. Plus i kept it at 55mph

 

I guess I'm impressed cuz I barely got 210 the last month I've been filling all the way up and finally now I got 322

 

That's pretty good... my sister's only getting about 200 miles to a tank in her '98...


I'm getting up to 735/tank, but that's 21MPG with a 35-gallon tank.... on a full-size van. Useful for getting through those periods when gas is expensive during summer.

 

lateralus did you say that you have an atx? and you put it in neutral to coast down hills? you should NOT do that. if you were in my area i would tell you to go ahead and do what you want (because i like working on neons with blown trannies!) if your at all interested, pm me and i will explane why i say this! [&:]

 

^why is it bad?

 

trannyinstaller--I don't know much about the fwd autos, but assume like rwd autos for last 5 or 6 decades---only one pump (some 50's had a rear pump that made it a non issue?) so if coasting in neutral it's like towing for longer periods--no lubrication, parts spinning=bad.

BTW--when I had my 5 speed sohc tuned more for mileage and had the compression up about half a point I actually got 42-43 a couple times on a commute that had 85% freeway at about 72. I had to run on mid-grade though and it was in CA at nearly sea level.

Pretty awesome when you see Hyundai ads proud of their 35 MPG and we could do it 10+ years ago.

I think I usually stopped when I got to about 360 to 380 miles on a tank--just to be safe.

 

well, i was gonna explane this to one individual, cause i didnt think you All wanted to here a long drawn out explanation, but i got a couple of pm's about it and it seems like you guys are actually interested. I was considering the same type circumstances as Red91RT was talking about, viewing a long coast in neu. much like a long tow, with the power wheels on the ground. however, even though i am a tranny guy, before i give an absolute answere i like to check myself before feeding you guy's information that may be wronge. I spent my whole lunch brake going through hydrolic diagrams and talking with my dad about this (he's a trans builder) and came to find that i was wronge!Although a mild hit to my ego[:@]id rather figure that out by actually checking into it than just assume. i figured that over a long period of time in a coast, that the coast clutch would suffer loss of lube and eventually get damaged, but after some mildly tedious (and boring) lechtures about pump opperation and hydrolic circuits[:'(]i learned that it really wasnt that bad, unless if done for some pretty long periods of time. You would have to be coasting for about a mile (at 55) before you could really see any damage.

 

Well Ive been doing this for idk how long bro. Ive been coasting in neutral at least over 50 miles hitting upwards of 90mph in neutral. And when i go to put it in drive i rev match so it doesnt jerk in. It doesnt feel like it does anything bad but if it does i ll let you know first.

 

I'm getting about 550km (342 miles) per tank with a '98 auto in the city. The Neon is pretty good on gas.
