That's lower in 4th and 5th than I'd take my 5-speed diesel.
Make sure you aren't lugging the engine.
Low revs are OK, but don't overdo it.
Does the engine still sound happy that low in the rpm range ?

Yeah only time i see were getting into 5th at 35 could be some what bad is if the road isnt completely level then i get a very tiny vibration but other than that its fine. Like I said engine is fine with it.

Does that also mean you lift off the right foot early enough ?
We use coasting as a (aerodynamic) braking technique, so you have to start way far further out than engine braking (lifting the gas pedal while staying in gear).
If you have to brake, coasting is the best way to do it - more so if you also switch off the engine (which is a step too far for my liking).

I find coasting to be somewhat difficult. Being on a military base we have a very few select roads that will get me to school or to the town. I try to coast as much as I can but dont want to interfere with the other drivers as well. Saying that I do see that most of my increase is from coasting. I also use engine breaking a lot (even though its wasting gas but at least im not idling with breaks on).

10-15 mph below what your usual speed is, or glides down to 10-15 mph ?
On board displays aren't always correct when you start things like coasting an P&G - what's the situation with actual fill-ups ?
|
I usually go from 55-40 on the highway or roads that are 55, that is if other drivers permit. On most roads ,as long as I can, I try to do a 10-15 mph range (eg. 45-30, 45-35).
What do you mean whats the situation with acutal fill ups?

Mine are at the tyre manufacturer's limits - that's 49-50 psi or thereabout.
Check what the max. pressure is for your tyres.
Anyway, 30 is low.
Winter tyres usually don't help MPG either.

Well on mine they say max pressure is 44PSi. Im thinking about airing them up to there but I just worry about how that will effect my car is the snow. Right now there isnt any but with the lake still unfrozen I foresee a heavy snow when it finally hits. Do you think this will cause problems at all
