I'm used to cars that like a drink! Today I filled up with 99ron fuel and pointed the old volvo at the motorways.. Surprisingly I averaged this over 200 miles or so! . And she's running cool atm too! Anyone else had some surprising figures on a good run?

Not a car, but I’ve got a 1200 Suzuki Bandit tuned pretty good with virtually every mod you can think of. It regularly returns 14mpg!!

I had a 50cc bike when I was 16, I put in a tank of 4 star once a week at about £1.60 a gallon, ragged the poor little thing everywhere and never ran out. I have no idea what the MPG was but I'd bet it's the best I'll ever see from something with an internal combustion engine.
I had a 205GRD that regularly hit 55MPG on a run.

A6 C4, with the straight 5 2.5 TDI.
Regularly manages 50mpg on general duties and has managed almost 65mpg on long trips when driven moderately. It’s not small, light or slow either.
Recently acquired an A8 in 2.8 2wd form. It’s early days yet but seems to do about 30mpg on general duties and best trip average over 250 miles is 37.8 mpg, which is pretty good I reckon and (unsurprising) significantly better than the 4.2 Quattro version I had a few years back.....

Nick Ditto with the A6 we had. It was brilliant on long smooth runs. I had a 99 Passat 1.8T and was able to get low 40s on a similar type of run.

Anyone else had some surprising figures on a good run? I have a Volvo engined Turbo'd Mondeo. It has the C30 T5/Focus ST lump. That gets 35MPG average on a run and around 30MPG with general driving. It's on 5,000 miles less than your car . I take it the 200 miles on your car wasn't done from a full tank? With a similar sized tank however, I'm seeing closer to 400 miles to a tank, if not more. Changing the thermostat on mine which wasn't quite as bad as yours made a bit of a difference. The M3? That does around 24MPG average, with around 33MPG on a run, which is not bad for a 340BHP car on ITBs. The Merc was terrible. The best that ever got was 17MPG on a run ; it loved a drink that one. A 90 litre tank barely got you to the 300 mile mark. Ouch!

I impressed myself once by optimising cruise control and restraint on dual carriageways to average 39mpg out of a BMW 728i over a 600 miles holiday cruise.
I had an early BMW 330d doing 49.9mpg and a 320d doing 59.9mpg as dailies a couple of years back. Could never get either of them to crack past that .9 which was soooo annoying.
Low record has to be the 9mpg average when driving the Cadillac back home on 7 cylinders. almost 500 miles at 9mpg. My wallet spent six months in therapy.

I'm another one who had the straight 5 Audi TDi lump and loved it. Replaced that A6 with a little Skoda Fabia tdi and it does much the same. Great engines.

I've never really paid attention to mpg in my cars. I enjoy driving and do so "spiritidly" on occasion and the added few pence it may cost is worth it in the grand scale of things. There are more expensive hobbies. I know people who will buy a car based mainly on mpg and obsess over driving as economically as possible. There is more to life in my opinion.

This has been my pride and joy for a few years. I bought it stock standard. I lifted the suspension with 3 inch, followed by a 2 inch body lift then 35 inch tyres, an exhaust, a little bit of engine work, bit more engine work etc etc It was a very fast and capable 4WD. However after taking it to the beach and showing of I calculated that my car just used ......2.82 mpg That was more than my brothers new prime mover truck..... I sold it soon after, but still miss it.

My daily is up to 13mpg now. It once did 30mpg, then I did 1 3rd gear pull at W.O.T and it dropped to 25mpg (that was after 30 miles on the M1)
Most impresive but boring was getting 39.9mpg out of my mk5 GTi going from Sheffield to Manchester over the Woodhead (A628) - wasnt through choice, sat behind trucks all the way.
My S60 D5 would get 50mpg sat on cruise control at 70
My old E36's (318is & 318ti) would get 400 miles to a tank (35mpg) going to the east coast and back, mixed driving

E61 525d Wagon, manual.
45.5 MPG over the last 80k miles. Not bad for a two ton barge with c.200bhp. On 160k now and totally original.
I will cry a bit when it dies.

This: has averaged 45MPG over the last 35,000 miles (I'm one of those people who keeps a log of it!). Can't complain given it makes a straight 6 noise too I don't tend to log the other cars so much, but the MX5 and Morris Minor will both do 40mpg on a run. The VW camper 25-30MPG depending on how I drive it I also consider anything that accurately tells you the MPG it is doing to be a modern car

Going very fast in something very silly in the early 00's flicked the display to instant MPG - showed 1.3mpg. Wonderful. P.

I've never really paid attention to mpg in my cars. I enjoy driving and do so "spiritidly" on occasion and the added few pence it may cost is worth it in the grand scale of things. There are more expensive hobbies. I know people who will buy a car based mainly on mpg and obsess over driving as economically as possible. There is more to life in my opinion. I do hear you there. With my Merc, I do care less about MPG than before. Anything 'normal' seems frugal to that, even a friend's C6 RS6. That said, I think all things being equal it can also show if the car has a problem, especially if on carbs, be it -Poor tuning -Poor carb setup in the absence of an AFR gauge. As two examples 2004 Mondeo V6 Auto 2.5This used to do 18-22MPG and it felt slow. Everyone said 'they're like that. That's rubbish. The issue (which I've come to realise is more documented in the 'States than here due to the rarity of V6 Mondeos is that the 3rd cat never warms up enough and will slowly break down over time. Ours eventually collapsed. We removed it so two of the 3 factory cats were left. The result? It actually moved very quickly. It drove more like a 170BHP V6. 22MPG was now the norm around town with around 30 on a run. That's not a performance or economy advantage to be sniffed at. Honestly, I could have told people that I had done an engine transplant, the difference was that large. The other time? Ian Seabook (HubNut's) Citroen 2CV6 652ccBoth his 2CV6 and mine ran the larger barrels with the Burton jets, which are said to be too rich ; Both of us got 38MPG which isn't to be sniffed at. Pete Sparrow rejetted Ian's using known jet sizes. Besides getting rid of a flat spot, he gained 6MPG in the mix as well. Finally, driving economically can make you faster and smoother. No braking around corners, which you can carry speed through on decent rubber (that still ties into the above), and approaching roundabouts right (i.e reading the road). A mate of mine gets 35MPG from his 1.6 Focus TDCi but he cannot cruise to save his life and doesn't know about 5th or 6th gear even when at the speed limit on the motorway That's my 2p however E61 525d Wagon, manual. 45.5 MPG over the last 80k miles. Not bad for a two ton barge with c.200bhp. On 160k now and totally original. I will cry a bit when it dies. E61s are great aren't they? My dad had an E61 535d SE, which I preferred in the SE state. That thing was lovely! I really wanted to buy it, but I could not justify it at this time. A friend however does have it, which is kind of nice, since my dad bought it off a mutual friend of that guy, who is also a good friend of mine . That was a little poorer on MPG mind you, but that power and torque were very very addictive! 33-41MPG was the norm. I can fully why people remap those 535ds. In SE form, it really was a sleeper.

Too many to mention! Lowest. Jeep Cherokee 4.0 with a caravan on going from a standing start uphill showed 1mpg all the way up! Modified crossflow in a mk2 cortina would do 17mpg no matter what (set up on Aldons dyno). Ford Pop gasser with a serious 351 Cleveland did 9mpg everywhere. Current pleasant surprise is wifeys Suzuki Swift Sport (sorry, not retro) which hovers around 50mpg despite being a hoot to drive.

I had a Fabia vRS (the 130PS 1.9 TDi) that did 50mpg as a minimum, not matter how hard you drove it, and 60 easily on a motorway run. My Lancia Dedra was really strange, in that it returned the same mpg (around 27mph) whether you drove it like a saint on a gentle motorway cruise or ragged it down B roads and kept changing down so as you could get boost.
