I usually cruise at 70, keep the throttle only on hard enough to keep you at 70 on the flat. DON'T put it down to go up hill, just keep it where it is. Let off when slowing down, try not to use the brakes. If you can slow down gently, then, by the time you get to whatever was slowing you down, you won't have to accelerate as much as you would if you waited until the last minute to brake.

 

Just don't have a lead foot, that'll help consumption

i find 65 gets u a lot further

 

i went from uni and back and work and back and did about 60 miles and the needle is still right up as far to 'fulll' as it goes. usually, i go 90+there and back but im skint so i need to save money too and if i do 60 miles at 90 then the needle has moved so there is defonately a big difference

well listenin to what you all said, im gona try going at 70 for 160 miles(near enough half way) see how much i use, shal i come down the gears when cumin to a round about or coast in 5th???? (clarkson said when he went from london to endinburgh and back that he cruisedIN gear when he slowing down and the wheels moved the engine and not the petrol while in neutral, i think what i just sed makes sense lol im tired

basically, yeah. coasting in gear, you're not using any petrol. The wheels are turning the engine. In neutral, you're using fuel as the fuel is keeping the engine going rather than the car's motion.

 

Depends what speed you're gonna be coming to the round about at, but coming off it, try to be around the 1800RPM mark. Don't race away, and change around 2,500 to 3,000 revs(about right for a Petrol. I'd be saying change around 2,000 to 2,200 in a diesel, Pulling away from the round about at 1,200 to 1,300 revs) Should see you saving the juice :)

yeah, you'd be surprised, really. I was sometimes surprised with the low-down torque my little Fiesta had (which started out as a 1.1 but later was dragged about by a little 1.3 HCS engine that was donated by a rotton MK4 Escort van. Good engine too, only done 58,000 miles! Not bad for £30, either!

 

Clocked up 30k with me without any real problems. No oil burning/leaks and the tappets weren't as bad as some i've heard!

 

Can't beat a diesel for torque though. Certainly not on a standard car!

If you're that skint mate, just sit behind a truck for as long as possible. I personally wouldn't do sub-60mph because I feel as I'm holding the traffic up! But if there's a truck there, they've all gotta overtake.

 

Anyway.... I just do 65 - 70 to save fuel. Any less and I just give up after a while and do 90!

Indeed, you sit there at anything around 56 and i'll reserve the right to knock you off the road with the front of my Scania!!!! :thumb: :D :D You just force all the 44 tonne 56mph vehicles into lane 2 making a motorway like a 2 lane road and all the cars have to use lane 3 to get anywhere, plus you'll make the blood boil of every trucker that has to overtake :rolleyes: :D
