I was at a friends the other day as I am doing a bit of fabricating for him. During our many conversations we discussed how well his dad’s RRC was looking after its re-spray. It is fitted with a 2.8 Isuzu TD engine and I mentioned that I liked the sound of them due to reliability and fuel consumption. This is when he said that the mpg on them wasn’t great.
So – What MPG do you get from your vehicle. Try to be honest and don’t say yours will do 30 mpg if it will only do that travelling at a constant 55 mph. Or perhaps we should put what we get on average, what we get urban, what we get when we nurse them (55 mph and avoiding the breaks!) and finally the motorway 70 mph run.
If we get enough useful data it may be worth putting it onto a spreadsheet so we can all see the results.
I am going to stick with my 3.9 efi as I don’t do enough miles in it to warrant changing. But I just can’t help it – I like diesels!!
Thanks in advance for any responses.
Just one thing – can we keep to your mpg’s and avoid criticising other vehicles/engines as if we do that the useful information we get will be reduced!

On the way to Norway (summer 2007) in my 110 200tdi in July (with 5 adults in it, full load area, roof tent & rest of roof rack full I got 27.5mpg cruising at 65-70mph (same on return journey)...IIRC this was about a 450mile trip from home to Newcastle.
Normally I get anywhere from 21-28mpg...depending how I drive it...not far in it's present state :lol:
My 90 2.5NAD gives me about 25mpg...although I have never checked it :oops:
My VW Passat 1.9tdi (154bhp) gives me 54mpg cruising at 80mph :dance:
...guess what get used most :roll: :lol:
-
my landy gets me 30ish mpg on a run (200tdi)
my skoda gets me 60mpg cruising at 70 :P (its a 1.4TDi)

How do you work out MPG? I know how many miles I do on a tank of fuel and how much it costs.
I do know that I am getting double the mpg running on straight veg oil compared to diesel. :dance:

Thats like 55mpg when you are on veg oil then. it might only cost half as much to run but it wont do twice as much to the gallon.

Look on your receipt for the amount of fuel you have put in your tank. Keep a note of the fuel amount and your current milage. Do this every time you fill up. As it is likely to be in litres, divide this amount by 4.546 (as this is the number of litres per gallon).
After you have filled up a few times and noted the milage you have done you should get an accurate mpg. Just divide the miles by the amount of fuel you have used doing them and this will give you an accurate average miles per gallon.
You can also do it by re setting the trip meter on your speedo when you fill up. This will only work if every time you fill up you fill your tank to the top or you may put a different amount in to that you have just used on your latest milage reading!

I know it costs nearly half the amount to buy but, I have only JUST passed the 3/4 mark on the fuel guage and I have done 220miles so far. I have done about 10miles on diesel from the small tank so say 200miles from top quarter of a tank on 100% veg oil. When I used to run on diesel I used to get 200miles at the half a tank mark. So at the moment it is looking to be near double MPG and nearly half price. Will see when I next fill up with veg oil. Long journey this weekend coming up :-)
As for the reset trip meter each tank full. I have always done that and always put in a full amount. If I dont put a full amount in I dont reset trip meter and add the small amount of fuel put in to the full tankfull the next trip to give same reading. I will work out MPG soon for you.

BMW Diesel & Auto Box:
Max 33mpg but very rare, that is all motorway and driving carefully
29 general driving long distance, some Motorway, some singe lane and some running around towns etc.
24 hard driving on the welsh lanes - that is on tarmac not on Green Lanes.
Towing most trailers doesn't really effect it much except that you can forget the 33.

19 being gentle, probably 11ish normally and 6ish in low box.
Not bad for a 2.4 petrol with a manufacturers claim of 29 average.

OUUUCH. My 110 V8 did more than that!!! think of the beastly V8 landy you could be running for the same price as your maverdick. obviously your garage bills will go through the roof but think of the noise!
i would be thinking seriously about a gas conversion with those figures.

300tdi 90 - 35mpg - motorway, off-road, motorway.
That was at 60-70 on the motorway.
-
Could go for a v8 or gas conv but it only does about 5 thousand miles a year so it's not that important.
Besides it uses fuel, i fill it up some more such is life when i can't afford to do that i'll sack it off for somat else.
-
just used that internet milage thingy, apparently im getting 11.82 mpg on my V8 disco on lpg, then realised im only paying 50p per litre for lpg so thats like 22ish adjusted mpg, (if you know what i mean)
quite happy with that !!
-
my 2.4N/A hilux pickup got around 50miles to £10, when fuel was sub £1/litre
disco varies a lot, the worst i`ve done is 110miles on £35ish, which was just after i`d tinkered the pump, and went joyrding with happy pedal to the deck everywhere.. novelty wore off at the petrol station!
generally i`m getting between 50-70miles on £10ish derv, although i do slip veg oil in up to 50% (weather dependant) so difficult to say exactly..
so with derv at around £1.09/l 50 miles = 24mpg
and 70 miles = 34mpg
i`ve been on a first aid course this week, giving me a 25mile drive each way... with the pleasures ( :^o) of a1 tyne tunnel traffic... (1.5hrs!!) and i`ve put around £60 derv, and a few bottles of sunny oil in... so, 200 miles (4x25 - with a bit of butty runs/getting lost) on about 55l = 16mpg....
driving to loud music (metallica) probably didnt help much!
but generally speaking my disco 200tdi gives 24-34mpg ;)

Disco 200 TDi Average 35 mpg mainly local runs maybe 12 miles max.
I zero trip after every fill up, always top the tank right to the brim.
Best ever mileage was 47 brim to brim on a couple of trips down to Hereford, cruising at just over 60 mph on motorways. That seems to be the most economical speed for my car, on 265/70s.

I think you need to look at your Maths again.
My Dad & I Drove Disco 22tdi's for over 15 years between us and 35 was a very good MPG, long run only job.
Yes 60-65 is a good speed but 47 is very optimistic.

If you drive a V8 it not MPG its GPM...
I'll get my coat!

I keep a record of my fuel consumption (always have done). Since July 27th 2007 - when I bought the current 300Tdi auto Discovery ~ it's returned an average of 23mpg (best 26: worst 21). Most journeys are short (less than 2 miles) on a cold engine but the highest mileage is on long trips (50+miles) on a mixture of motorway and A road where I always try to keep within the speed limit.
My previous Discovery (1996 3.9 V8 manual) gave an average of 16/17 mpg on both petrol and LPG with the same journey mix.
1995 300Tdi manual Discovery averaged about 30mpg with mostly long journeys and very few short ones. Best it gave was 36mpg on a trip to the south of France and back. Coming back it was so loaded up I had to leave 2 bottles of wine out [-X (there were three but I drank one the night before we headed home :clap: )
1991 200Tdi manual Discovery averaged 35mpg on a right mish-mash of trips.
-
I've got a vx frontera with a isuzu 2.8tdi LWB ...and if i drive it properly (my right foot is made of lead) i can get 38-40mpg on a run
around the town ...only get low 30's
-
The series gets about 35mpg on a run with a 2.5di transit engine, was 39 before the new tyres. The 101 gets about 10 though.
-
I get about 10mpg from my 110V8, but it's only ever short trips and never really gets on a long run these days.
I also manage over 50mpg from my BMW, which is why I have it!

I see your not a biker then :evil: :evil: :evil: :evil: :evil: :evil: :evil:
Wouldnt it be briliant if someone had an accident just for the sake of you checking your MPG.

-
Between 26 and 28 mpg.
-
I'm certainly no longer a biker, age, and screwmatics make it no longer a good idea.
Nor do I drip diesel down the road, maybe because I no longer try to corner like a bike, and it's a tad too expensive to chuck away.
Reason I zero the trip every fill? Guage hasn't worked for the past four years, not a problem, first Landie I ever drove didn't even have a guage fitted.
Look far enough down the road, and drive according to conditions. It's amazing what a difference it can make to consumption, particularly on a long motorway trip.

Well, I used to get to about 300 miles before the needle dropped to the halfway mark. Seems to be a case of being lucky to make it to 250 miles before that happens now...
-
13mpg from the disco v8i currently
23 mpg from the mk1 pajero 2.5di
16 mpg from the old series 3 county petrol
-
My 2.5 petrol 90 does abou 8-10 through town & about 13-15 on a run :shock:
The words "haemorrhage" & "money" spring to mind!

:shocked: ouch .

Muck my 1988 Range Rover 3.5V8 Efi has averaged 14 MPG since I bought him 5 years ago. That equates to an average p/mile of 27.5p and that has increased by about 10p in 5 years!!! But I only use at weekends and lots of short runs in between some longer trips to pay and play days and shows. Best MPG on a long run was 21 MPG worst was 6MPG :shock: . I just fitted a new stainless exhaust and K&H filter so i will be interested to see if they have any effect.
Brass (after all where there is Muck there is Brass!!) my Discovery 3 TDV6 averages 30MPG but on a good run I am getting 34MPG. Its a company car so they pay the fuel I pay the tax!!
Its not what it cost its the fun you have behind the wheel :dance:

kn filter save a bit but it all helps :dance:
-
110 V8: around 10-12mpg
110 TDi: around 30mpg
Disco V8: around 20mpg on petrol and 35mpg on gas
OUUUCH. My 110 V8 did more than that!!! think of the beastly V8 landy you could be running for the same price as your maverdick. obviously your garage bills will go through the roof but think of the noise!
Why would his garage bills be higher? We've had our 110 V8 for nearly three years now and the only thing I have had to replace (apart from normal service items) was the alternator. Our 110 V8 is the cheapest (apart from the fuel costs) motor to run I've ever owned :dance:
-
My 200Tdi with Allisport Full Width intercooler. ITG foam air Filter and silicone Hoses does over 33-34 on a trip. I stick under 3000 revs as per the book. Around town im getting 26-27. So thats how i got the intercooler past the wife. :)
-
Right then. I have done a long journey / running to and from work on veg oil and this is my result.
I did 367 miles and the guage needle was still above quarter of a tank. I put in 54litres of veg oil (this is all I had) and the needle still wasn't up to the usual full mark, (just below ful mark. usual needle goes slightly above full mark) so I guess I could have got another 10litres in.
So going on 65litres and 367miles (using the groovey link someone posted) that makes it 25mpg.
Since refil I did 220 miles today and needle is down to half way and most of that was motorway miles. So this tank may not be as good mpg.

Just joking. infact all i ever did to my 110 was the rear shoes. never let me down. only cost me a grand and it went straight through the MOT. 180k on the clock as well.
-
the best mpg i have had in the last year and a half is 24 mpg without my roof rack, its a 200tdi seem to get from about 18 to 21mpg on average :embarrassed:
-
I used to get 18-21 before the veg oil conversion but then it stayed in the low 20's after I changed the air filter. My air filter was incredibly bad and suffercating the engine. :oops: :shocked: :roll:
-
Looks like the 200Tdi has a lot going for it (on the fuel side at least!). I am quite impressed with the results.
The best mpg I have had (and this is going off the trip computer thingy) was 72 mpg in a Skoda Octavia 1.9 Saloon. It was on a 42 mile trip including A roads, duel carriage way, motorway, then the twisty + hilly mile and a half at the end of the motorway! I nursed it for the whole of the journey just to see what I could get out of it (keeping to 55 mph, anticipating traffic lights and keeping the foot on the clutch if I did not need power etc.) but I was still impressed as it was a decent size motor.
On my 70 mile trips to work (in the morning including the M62 past Huddersfield/Leeds at 7 to 7.30 ish in the morning) it would get between 45 - 50 mpg.
I am still impressed with the 72 mpg though (and that included having three tool boxes in the boot!).
Thanks for all your posts.
