30.27 Mpg :d
436 miles
14.4 gallons
30.27 MPG
Drove without the A/C on at 65 mph, no cruise control. I made 2 stops (each lasting more than an hour, so the engine cooled down)

Strangely in Oregon MOST people DO go 65 to 70 mph. If you stand out, you get pulled over. Lots of cops on I-5 just waiting to bust someone who stands out...

They are low rolling resistance tires, the bad side being longer stops (not by much though)

lol, youve menchined your tires a countless amount of times for better mileage... and its obviously a bigger factor than i thought. nice one.

hah i get like 14-17 mpg... if I'm lucky.
Every block next to me has a stop and the expressway is a virtual standstill 24/7. Among everything else here. I'm probably stopping and going less than every 100 yards or so. So that's definitely a reason.

Do you really save on gas from driving 65m/h compared to 80m/h? My thinking is, assuming you'll have 500miles to drive. If you drive at 65m/h you'll get there in 7.69hours. Doing 80 will get you there in 6.25 hours. therefore I think eventhough you use less gas/mile driving at 65m/hour, you're going to spend more time on the road thereby consuming more gas! Any thought on this??
#16
Yes. You use more gas driving at 80 mph than driving at 55mph because the engine does use more gas trying to keep the car going at 80 because of the drag. For many cars, 55mph is the optimum speed for fuel economy.
Ken, you suck!! As for a tank of gas, the best fuel economy I can get is 23mpg mixed. But since I've gotten the ScanGauge to check, I can actually get up to 28, 29mpg per trip.

I guess you only save on time

Yeah that definitely lowers it.

90 -----> 8100 (=90 X 90)
So, the drag force at 80 is over 2 1/2 times greater than the drag force at 50. It is all physics.
Ken is right though, up to about 50 MPH, your engine efficiency gets better and better with increasing speed because the engine and transmission is designed for efficiency at higher speeds. Above 50 MPH, the drag increases are so significant that they overwhelm the engine and transmission benefits and your fuel economy begins to drop. It is all physics - anyone who claims to get better gas mileage at 80 mph than they do at 50 mph is essently claiming that their car can "walk on water" (without regard to the laws of physics.)

Some free K&N air filters up for grabs on Acura World.com. Look on their homepage. Maybe that will help your MPG's ?

Here is a simple drag factor table:
Speed -----> Drag Factor (=square of speed):
0 -----> 0
5 -----> 25 (= 5 X 5)
10 -----> 100 (= 10 X 10)

yes. around 55 mph is the most efficient speed for most cars, especially manuals!
most car engines operate at most efficiency at 2400 to 3000 RPM. if you can achieve that range in the top gear of your car, it will most likely be around 55 miles per hour.
the highest gear of your transmission will exert less force when applied to the engine than in any other gear. That's why you take off fast off a stop in 1st gear. ever tried taking off in 3rd or 4th? if you can do it without killing the motor, you will go extremely slow. sorry if i'm confusing, i think i know what i'm talking about? hopefully?

I posted it and of course everyone said that it wasn't possible and I just miscalculated, but it wouldn't even hold 2 gallons after the trip (something like 1.9 gallons).

Factors such as wind (head wind/tail wind/side wind) will greatly affect your mileage. Also I have had problems in filling up my TL (99) to the brim. Sometimes it just won't fill up all the way so it is hard to determine exactly what the mileage is. Also / please post your car year/type. Some posts don't have this info. I experience 23-29 so far in daily city/high driving. The more highway, the better the mileage=of course!
