Jazoli Posted August 9, 2017 Share Posted August 9, 2017 My new (to me) astra H 1.6 twinport has amazed me by doing 47mpg on its first tankfull, I'm seriously impressed, my 1.6 focus did 34mpg on the same commute. Actual not obc figures. Link to comment Share on other sites More sharing options...
DodgeRover Posted August 9, 2017 Share Posted August 9, 2017 Bah brimming the LPG showed 19.8mpg, just done another 210 miles and it's showing 25.8mpg will refill again tomorrow and see what the real figure is.By the time I refuelled we had done 230 miles and the OBC had dropped to 24mpg, full fill calculated 20.8mpg Link to comment Share on other sites More sharing options...
Roverageous Posted August 10, 2017 Share Posted August 10, 2017 Last tank calculated brim tho brin in the V6 Rover came in at 35.3mpg - pleased with that! That’s 460miles to a tank. My diesel is only doing about 520! Link to comment Share on other sites More sharing options...
Asimo Posted August 10, 2017 Share Posted August 10, 2017 319 miles in SWMBO's 2.4 Suzuki yesterday; North Wales and back on A roads showed 38.3 mpg, which for a little black TonkaToy is pretty good. That would be about 35 miles from a real brim to brim gallon. Link to comment Share on other sites More sharing options...

cpjitservices Posted August 10, 2017 Share Posted August 10, 2017 Not sure what the Rover is achieving in terms of MPG, I stuck a tenner in on Thursday for MOT. After the MOT and pottering about town and to/from work I've achieved 24 miles and the fuel light has come on. I got 56 miles out of £20 before I;d stuck that tenner in. Not too bad really...

spartacus Posted August 13, 2017 Share Posted August 13, 2017 I've just filled the ex Krujoe 106d up for the first time. In mixed motoring with a tendency towards urban stuff, driven normally, ie. not trying too hard to be economical, it's done 64mpg. Calculated from a full tank to full tank.

Roverageous Posted August 13, 2017 Share Posted August 13, 2017 When I was about 12 I made a folder of running costs per mile for various new cars. This was based on fuel price alone and the one that sticks in my memory was the Daewoo Matiz which would cost 10p per mile to fuel. I was thinking about this when I filled up the other day. I always brim my V6 75 so it’s nice and easy to do a tank-to-tank MPG calculation. I paid 113.9ppl for petrol, and filled up with 58 litres (55l tank, so assume I’m filling some pipe work too). Over my last full tank I achieved 452 miles. The cost of the fuel was £66.13 which over 452 miles equals 0.146. So my notoriously thirsty V6 petrol costs me 15p a mile to fuel. I don’t do 12000 miles a year, but if I did the extra cost in fuel to drive a Rover 75 vs a Daewoo Matiz is £600 a year. This doesn’t take into account that fuel was also cheaper in 2002 that it is now - so there’d be even less of a difference. Where have I gone wrong?!

Guest Hooli Posted August 13, 2017 Share Posted August 13, 2017 Fuel isn't the main cost in running a car if you are talking from new. Add the cost of servicing/tyres etc in & you'll see a lot bigger difference between a 'premium' and 'cheap' car. Lacquer Peel 1 Link to comment Share on other sites More sharing options...
Roverageous Posted August 13, 2017 Share Posted August 13, 2017 Without a doubt - but the whole thread is about MPG and the swing to diesel in the last few years is purely about fuel cost, at least for the private owner (let’s not get into company drivers and BIK!). I’ve rechecked and the Matiz would actually be 8.4ppm. So over 12000 miles the difference would be more like £800. Still looks like good value to me.

Guest Hooli Posted August 13, 2017 Share Posted August 13, 2017 Yup, sounds good value to me. Another example is Hairnet's 500cc commuter bike, that does about 60mpg he says. My 1400cc monster does 42mpg, well worth the difference in my book. Link to comment Share on other sites More sharing options...
Roverageous Posted August 13, 2017 Share Posted August 13, 2017 It actually makes me look rather silly for buying a diesel 75 for day to day duties which achieves (wait for it) 39mpg (auto + 160 remap + heavy foot). Link to comment Share on other sites More sharing options...
Guest Hooli Posted August 13, 2017 Share Posted August 13, 2017 I get 28-29mpg from a petrol Saab turbot auto (187bhp if they've not all escaped) in normal use. Link to comment Share on other sites More sharing options...
myglaren Posted August 13, 2017 Share Posted August 13, 2017 A couple of my kids and grandkids have had my C5 2L HDi up in Scotland, mountain biking and have achieved 57.2mpg with the car fully loaded.Better than I have ever managed. They did 700 miles before filling it up. Link to comment Share on other sites More sharing options...

I keep switching to be honest. My car history goes petrol, diesel, petrol, diesel etc... Some petrols have been great (8v Vauxhalls!), Others not so. I must admit out of the petrol and diesel 75s the petrol is the better suited to the car. It's not as quick as the diesel but there's no vibration and sounds lovely. I'd probably take a 4 pot diesel over a 4 pot petrol though. Sent from my Pixel using Tapatalk Link to comment Share on other sites More sharing options...

lisbon_road Posted August 13, 2017 Share Posted August 13, 2017 This thread is about mpg figures. I get 40 mpg from my LPG Astra Mk3. I pay about 53p/litre from Countrywide or some others. That equates to 6p/mile for just fuel. I have coaxed 55mpg out of it on petrol, and I hope to get the LPG figure up a bit by improving the ignition timing. I doubt I will get to 5p/mile.

reb Posted August 14, 2017 Share Posted August 14, 2017 It's probably about the same weight as a small diesel hatchback in 2017.As far as I know, there's not much weight difference between my 850 and my golf. Light volvo, heavy golf. I just looked it up because it's raining and I don't want to go out to look at the plates. Volvo is 1412kg, Golf is 1239kg. There's not a lot in that!

reb Posted August 14, 2017 Share Posted August 14, 2017 On an 850 related note, I've spent well into triple figures on fuel since I picked it up on thursday, so this probably isn't the thread for me. Sent from my SM-G935F using Tapatalk Link to comment Share on other sites More sharing options...

Guest Hooli Posted August 14, 2017 Share Posted August 14, 2017 Brim to brim in the Saab got me 27.24mpg for the last tank full. Dash shows 29.1mpg currently but is due to drop as it's done long trips recently. Oh & it was still running fine with 3miles left on the range display.

Pete-M Posted August 14, 2017 Share Posted August 14, 2017 Best MPG I've ever acheived was in a Škoda Superb 2.0 TDI DSG estate. Picked it up in Cheltenham on 1/4 tank, got home and it still hasn't gone into the red. Checked the avg consumption and according to that it had managed 75.4 mpg. As I'd not put any fuel in and driven the thing 166 miles, I believe it. Link to comment Share on other sites More sharing options...
djoptix Posted August 14, 2017 Share Posted August 14, 2017 My Espace returned 26mpg on its first tank, which was one drive back from Leeds to Bristol and then pootling here and there. On the current tank it says it's averaging 18.4mpg. FML. It is fun though. Lacquer Peel 1 Link to comment Share on other sites More sharing options...

The readings my Jag puts out reek of bullshit, 199 Liters per 100 is its favorite readingFrom what I know, they variously use a lookup based on the airflow sensor, or based on the amount of fuel that should be going through the injectors. There's probably other more black magic ways of doing it too. Sent from my SM-G935F using Tapatalk Link to comment Share on other sites More sharing options...
