Music vs. Fuel Mileage

[foamypirate]

I got 37mpg highway on a trip with my music cranked. I also got 41mpg earlier on that trip with it turned down.


And for those mentioning weight as dropping mileage...hardly. The only time you really burn additional fuel with extra weight is when accelerating. That means the effect is almost null on extended highway trips. In city will be different, however, because are you constantly accelerating.

Would an after market high output/more efficient alternator increase mpg w/ an after market stereo then?

Foamy, you always get high gas mileage.
But it all depends on the accessories.

Wonder how it is for someone who has a light show in/on their CB7. Haha!

Haha, yeah. I love it.

I've been looking at buying a newer car with working AC, but with the mileage my CB gets, I'm having a hard time! I have a feeling if I bought a new one, I'd never drive it, hehe.

The best i can get so far has been 33mpg... the only thing i can think of that might be hampering me is the 80w90 syrup spinning in my transmission

that is a very good question... if its more effecient then in theory...

this makes me rethink the size of the sub and amp i wanna get...im thinkin x2 type r 10's with a mild amp instead of the 12's with a fat amp

its not only the alt working harder that decreases your gas mileage. the big draw in power also cuts down the amount of spark that your engines getting. weak spark means more unburned fuel, which makes the engine work harder. i was sitting at a stop light at idle and turned up a very long bassy tone. the draw was so great that my fuel pump started to cut out and the car stalled. luckily there was still enough power to re-start the car. gotta love optima.....

Wow this is all interesting info and good to know. I always thought of weight not alternator strain. Good to know for when i get my system in.

I'd be more concerned about the added weight from the subwoofers.

I cant really help but would love to know how you can get 800km out of a tank??

thats like 37mpg thats civic territory..

and someone else saying 41mpg thats like 900km.

not doubting anyone but you guys sure your doing your math right.

how can you guys pull that kind of mileage..

Full tune up on my car, with a very healthy motor.

I did air filter, fuel filter, spark plugs, wires, rotor, valve adjustment, fresh oil, fresh coolant, fresh ATF (yes, my car is automatic), set the proper ignition timing at the distributor, etc.

It helps that my motor compression tests at 175 psi on EVERY cylinder.

hmm with an auto also.. have you ever had a GPS in your car?? I have found atleast on my accord that my Odometer runs a bit faster then "real life".

my car is in prime running condition but with a 5sp so my mileage should be better but I can only pump out 650km on a tank.

and thats rated better then what Honda says my car should get.

did you run your tank to empty or atleast the light and had 800km on your odo?

sorry for asking I just would love to hit 800km a tank.

I find that extremely hard to believe. When i can be a civilized driver, the best ive gotten was 28mpg but i have a little extra weight on you since i have a wagon but when the pedal hits the floor........well im gonna say about no more than 15 mpg lol. DAMN YOU GAS GUZZLING TURBO!!!!

[Julianachos]

180 mile trip ÷ about 5 gallons of gas filled = average of 36 mpg.
