Y2ACP Posted March 3, 2019 Report Share Posted March 3, 2019 Around here Huddersfield there are a lot of hills,a friend of mine will only use his petrol for going up hill and will coast wherever possible.He would rather buy disks and pads more often to (rest) the engine and save petrol.Comments/facts please.

Rich Posted March 3, 2019 Report Share Posted March 3, 2019 Unless he is turning the engine off then he isn't doing it as well as he can. I used to have a switch for doing precisely this. 1 Quote Link to comment Share on other sites More sharing options...
mk2 Posted March 3, 2019 Report Share Posted March 3, 2019 Go the flat long way, or the short hilly way. Which is more economical. Discuss. Sounds like someone is doing the automotive engineering uni course. Quote Link to comment Share on other sites More sharing options...
Sausage Posted March 3, 2019 Report Share Posted March 3, 2019 Used to know an astrophysicist when i was young who would do this all the time and insist it was the best way. But he would floor it and coast even on the slightest gradient. Total fruit loop but you couldnt argue with him about it as he knew best. But suffice to say his driving was erratic and quite unsafe. The engine at idle is using the same fuel as the engine on over run and in gear. Also you have greater control of the vehicle in the correct gear with engine braking than neutral or with the clutch down. I've done it in the past, but when you suddenly need to slow down and have proper control of the vehicle then gears is the way to go. Engine off saves the fuel but you have no power steering and brake servo beyond one of two presses of the brakes, also steering lock if you mess up the key.

Rich Posted March 3, 2019 Report Share Posted March 3, 2019 Use a switch, doesn't lock the steering. Brake servos are for pussies. Ditto Pas. Google the golf ecomat, uses digiswing, two batteries and some electric aspects to take care of the above. Quote Link to comment Share on other sites More sharing options...

Blue Loop Posted March 3, 2019 Report Share Posted March 3, 2019 (edited) I just think life's too short to worry about that little difference in consumption really. Plus I always found more entertaining to find out how much fuel I could make the SDi use Edited March 3, 2019 by Blue Loop Quote Link to comment Share on other sites More sharing options...
Pete Posted March 3, 2019 Report Share Posted March 3, 2019 Kill two birds - drive down hill, knock it into neutral and bounce the throttle off the limiter. Quote Link to comment Share on other sites More sharing options...
mk2 Posted March 3, 2019 Report Share Posted March 3, 2019 Just got back from Kent today after doing about 230miles. Bad very wet driving (increased drag) but still managed 75mpg, based on the fuel gauge being in the exact same place as when I left, 14L. Relatively level driving the whole way. And I even had the the little yellow jelly fish reminder light on in the instrument cluster....... Quote Link to comment Share on other sites More sharing options...

mk2 Posted March 3, 2019 Report Share Posted March 3, 2019 No one picking up on my jellyfish symbol...? Someone else pointed it out to me. Never noticed that it's a jellyfish before. My life is ruined. Quote Link to comment Share on other sites More sharing options...
Rich Posted March 3, 2019 Report Share Posted March 3, 2019 (edited) You'll just need a brake light sensor or something. Go start a thread about it. Edited March 3, 2019 by Rich Quote Link to comment Share on other sites More sharing options...
mk2 Posted March 3, 2019 Report Share Posted March 3, 2019 Rear fog light warning indicator. Looks "exactly" like a jellyfish on its side. I can't look at it the same way ever again. Quote Link to comment Share on other sites More sharing options...

mk2 Posted March 4, 2019 Report Share Posted March 4, 2019 The PD engine change must have taken a while. Still going at 3 in the morning.....? Quote Link to comment Share on other sites More sharing options...
Rich Posted March 4, 2019 Report Share Posted March 4, 2019 Nah, I left that at six. Only so many driveshafts and dogbones you can do in the rain before you get sick and do the bare minimum to make it work so it can be moved. Quote Link to comment Share on other sites More sharing options...
