What RPM range do I accelerate and shift for best fuel economy?

Ok I tried accelerating around 2500-3000 RPM from every stop. While I got up to top gear much more quickly, my gas gauge dropped much more than usual.

So maybe this technique does not work for my car OR I am doing something incorrectly.


HELP?! :/

I talked with a state road worker who put in the mile markers on the highway to find out how it was done. He said he got in his work truck and every mile by his odometer they got out and put up a sign.

Probably better to use your GPS for actual mileage and speed.

I'm still experimenting too. I don't notice any more enrichment even if I accelerate to 3500 rpm. I've been revving to that in the first two gears and skipping to 6th. With this vehicle it takes everything its got, loaded and A/C to accelerate fast enough to enter traffic without getting run over so sometimes I have to get into 3rd pretty hard too. I do notice a huge difference in reported mileage as I go through the gears. Its something like 1st(8mpg), 2nd(11mpg),3rd(18),4th(23) and from then on I'm drastically reducing load. I still see 20-24mpg in 6th climing moderate hills I guestimate 60-70% load but I'm not pushing the pedal down very far (maybe quarter of the way). One one downhill spot from a stop sign I go through the gears without getting above 1500 rpmand almost no load because I can take my time and let it build speed from gravity too without having to worry about traffic running me over.Mileage doesn't look much better than above until I get 5th or 6th gear.

I DID IT!

I drove 504 miles this past trip cycle in mixed traffic and averaged 37.4 MPG!!!

This is the most I've ever earned and I'm very proud of myself!

Excuse my excitement, I'll calm down lol. I just can't believe how well I did in such a big car as the Camry. WOOHOO! My biggest changes were implementing DWL and not using air conditioning. I've listed my fuel up in my garage along with what I did differently from my last trip cycle.

My new goal is to reach 40 MPG average

Wow! Man, you nailed it! I'd be excited too. That's killer mileage

Thanks, brother! I'm more motivated than ever now!

It annoys me that whether I accelerate at low RPMs or high RPMs, my fuel economy stays low regardless until I get into Overdrive.

I also hate accelerating uphills. Gravity is no help there. I wish there was some way to minimize the decline in fuel economy.
