Re: Gas Milage!!

I get about 350 km to a tank on my Mercedes. 4.5 L V8, tank is 80 litres.

Re: Gas Milage!!

I think my worst tank on the TDI was 600-700km, but... that was going over the coquihalla with two people, the car full of stuff and towing a trailer with a motorcycle on it.

In my 1999 F150 V8 4.2L with tow package, the tank was 90L and I would get 600-800 km depending on the how much of a slow acceleration I did. In 4WD it would go down, but then if I was in 4WD I wasn't really paying attention to gas anyway.

My 83 Chevy 4x4 with a modded 350, 4 barrel Holley, 4 speed, with an eight inch lift on 35" tires with 4.11 gears was a little hard on gas ... think it was @ 7-8 mpg

what do it win?

Re: Gas Milage!!

Put a ChipExpress module in the 3.0 Diesel Grande Cherokee. After quite a bit of tweaking power went up from 218 hp - 375 torques to 280 hp and 510 torques. Mileage went down from 11.8 litres/100 to 10.4 litres/100. Water meth is installed but not set to come on but I am expecting another 50hp and another 10% drop in diesel sucking once it is setup. And yes it is faster than a 5.7 hemi GC and yes it will out tow one up a hill.

Anybody here running Water/meth or propane injection on a Diesel??

Re: Gas Milage!!

Got 261.0km of city driving at the half tank mark in my 24V. Still working on the shift points, 2500rpm on flat road, 3500rpm going uphill, 6th gear downhill, neutral to red light and stop signs.

Being in neutral while slowing down for red lights and stop signs is not only harder on ur brakes, but it's unsafe to just be coasting. You should always be in gear just in case something happens, unless stopped or shifting gears.

Re: Gas Milage!!

I've done Calgary to Vernon, 557 kms on 3/4 of a tank in the R, around the city im usually just shy of 500km/tank

Not only this but it was testing on Mythbusters. It is better for fuel economy to stay in gear. In neutral, the engine has no resistance, it is just idling. When you are coasting in gear, you are slowing down faster and the engine isn't really "running" coasting and turning the wheels is turning the engine keeping it running with less fuel usage than at idle.

Gotcha, I'll see what I can get out of the rest of the tank. PS: how does neutral effect braking distance? Is the braking distance shorter in gear or in neutral?

Re: Gas Milage!!

Distance is shorter in gear because energy is dissipated moving the crank/pistons/flywheel whereas neutral is just wheels/brakes.

It's not really about breaking distance. Although I assume breaking distance would be shorter if you see down shifting and braking at the same time. Anyways.

If for some reason you need to accelerate out of the way of an oncoming vehicle, if you just coasting, you have to push the clutch, select a gear, release clutch, and then accelerate out of the way.

Instead, if you are already in gear, all u gotta do is step on the accelerator to more.

That half a second or whatever could potentially save your life.

FWIW...a diesel uses ZERO fuel when coasting in gear.
