Im curious to know what kind of rpm range everyone on here likes to shift at when doing daily driving in the city?

What would be the ideal rpm range to shift on a stock gear GT to achieve maximum fuel efficiency while getting through all 5 gears with some decent pull in city driving.

I always wondered about this and looked around for a thread, but found nothing.

So everyone post up what rpm range your shifting at for daily driving (not your range for ripping a new tincan hole on the Honda next to you, lol).

And if anyone knows the best rpm range to shift for maximum fuel efficiency please post!!!:bigthumbsup

I shift by sound in city driving. I don't even look at the tach.

Shifting advice

I get around 14-15 MPG city in my 91 GT with a five speed. I know that we are not comparing apples to apples but I try to get out of first gear as quickly as I can. First only gets you so far anyway. You may get better mileage if your car can start in 2nd. My GT is modified a bit and has enough torque to pull me out of 2nd so I generally do that. As for a shifting range, just remember that the higher the rpm's you pull in the lower gears will make for worse gas mileage. My GT has a pretty good pull above 1500 RPM's in most gears. Around town our speed limit is 35 on the main roads and I do that in 3rd at around 2000 RPM. I would shift into 4th but it bogs a bit.

Obviously, the quicker you can get into 5th on the highway is the quicker you will get your mileage will increase. I know this might not seem related but my grandmother has a late-model Bravada with and instant mileage data screen and if you leave the car in 1st or 2nd and punch it, the mileage drops off. The sooner you get into the higher gears, you immediately see the mileage go up on the computer readout.

Like I said, 3rd or 4th are good around town gears that have plenty of pull to get you around without too much delay while delivering good mileage. Keep in mind that I do warm up my car for a few minutes before I leave and I run the defroster and/or heater on the way to work so mileage has dropped off a few MPG's since last summer.

Hope this helps!?!?!

The RPM’s you are running the car at are less of a factor than how much throttle you are giving it. It’s not a one dimensional solution. There are multiple events that make up your MPG.

Ni idea what's best for fuel economy. But like Stl I normally shift by sound. Generally I think if it gets over about 2500 I up shift and if it falls below 1500 I downshift.

One of my co-workers justified WOT acceleration up to his desired speed as more fuel efficient than slowly accelerating because he was taking advantage of the engine's volumetric efficiency.

I wish I could take credit for that one!

I'm never below 4,000 RPM at any speed. I shift at high 4,000's normally and at 5,900 when stabbing it. Mileage doesn't matter but sound does! I bought this car for fun!

yeah some times i even shift at like 2200, but you just have to read the feedback your car is giving you. I know when i cant up-shift, unless i want to face the embarrassment of stalling. haha.

Usually closer to 2500 than 3000. I don't normally get into 5th before about 50 mph. The book says the minimum for 5th is 40 mph.

I usually shift betweek 2,000 and 3,000, trying to have a little fun while getting decent gas mileage. I drive about 75 miles a day, 3/4 highway 1/4 city and usually get 24-25mpg. Although sometimes there is just no way to keep it under 3,000rpm, or 4,000......... or 5,000..........:gringreen

Heavy traffic, 2nd at 10mph, 3rd at 20mph, 4th at 30mph, 5th at 40mph. The rest of the time in normal traffic with normal driving conditions I get to 40mph with 1 less gear. I usually get over 18mpg with minimal highway cruzing(averge speed 29mph).
