'ello.
The 'trip comp' is working fine on all of the settings, but it has been generally indicating mpg around and above 40mpg. The car has only just come back from a major service and MOT and the engine was polished and ported by the previous owner, but this sounds too good to be true, doesn't it? The driving has been mixed, motorway, town and giving some welly. Any other valvers getting this sort of mpg?
If this is fairly accurate then result, but I have this sense that it is overcompensating by 5-10 mpg.

LYING!!!
You'll be looking at around 30mpg, I get 32mpg out of mine on a long run
-
Glad this has come up as mine is giving an average of 37mpg. This is from a 91 8v. Im sure my little computer is telling me fibs, although saying that it is very good on petrol!!

Thats close to what mine is saying and after working it out several times it appears to be very acuurate but 95% of the time I do drive very steady (rarely over 65 ect)

Here's a picture of mine below:

I would guess 'lying' :wink:

that would be about right on an 8v

i did a couple of hundred miles trip in my 90 8v the other day, was in traffic so averaging about 50 behind lorries etc but overtaking in 5th now and again and mine was reading 43.3 which i thought high as normally its about 36-38 ish but got my little calculator out and worked out how much petrol it used when i refilled and the mileage and it was near enough bang on give or take a few decimal places! i was over the moon, although it does have a new engine and has just been sreviced lol! :cool:
-
Mine reads between 6.0 to 9.0 now im worried :shocked:

Mine did that!
check for a loose vacuum pipe by the expansion tank/fuel pump, with the engine running you might be able to hear a sucking/buzzing noise around that area.
its a hard plastic thin pipe which has something to do with your MFA readings but can also play with your air/fuel mix i think?

check near the end of the inlet manfold,(gearbox side) there should be a couple of yellow looking one way valves i think they are, in a vaccum pipe, mine did exactly this and there is a little 90 degree joint coming out of the valve, which had snapped off so i just connected the little pipe to the other yellow valve and sealed the old one up, no probs now!
-
my mfa worked until i got new clocks. god daym car!! :grin:
-
my motor is a 16v by the way and it seems to be fairly frugal when i'm not rorsting it. If I cruise it does very well.

Could be running a bit lean. I've seen 40mpg+ on my 16v before. But not since its major rebuild in 2003.
-
I'll have to get it to the garage next month to see if it is running lean, along with the dent in the passenger door and the sunroof which won't close properly. :rolleyes:
-
i was getting 45-48mpg without tonking it and when i did the maths conversion it was about right, but it was pinking as i forgot it needs super unleaded and not just normal - thankfully someone on here put me right! :embarassed:
-
I have yet to put a full tank of high octane petrol in it yet, so will be interesting to see what the difference in economy and performance will be. It has about £20s worth of 95 ron at the mo, drives smoothly on this tho and it doesn't appear to be pinking.
-
Mine said 60.1 mpg the other day!!!! :smiley: If only!
-
Update - twas 3am coming home from work (late shift) cruising at 70 mph on A12, following wind, no traffic and tank filled with £30's worth of V-Power earlier on in the day and I spotted a new record on the MFA - 51.4 mpg!!!! Surely the first 16v Diesel in the world :grin:
-
I'm lucky if mine reads above 12mpg or 30mph. Only thing I use my MFA for is oil temp.
-
:grin: fill up to the brim - reset ya trip - drive til empty - fill up - then do the maths .
My MFA is about as reliable as Great Western Trains when it comes to MPG :grin: :laugh:
