Griffith fuel consumption
Discussion
I know this is a topic that often strikes up: 'Who Cares?' But for what ever reason never been bothered about how many MPGs i'm getting. However returning my car from Blackpool down to the West Country a week last Saturday became the excellent opportunity (which I did not set out to do) to find out! I filled the tank right up (as you do!) at Blackpool and headed south with a few added minor detours on route and then my next use a couple of days later with less than quarter in the tank I drove further south to Warminster - With the aid of Google maps this came to exactly 250 miles. When filling up the tank again, this came to £52.28 and I had placed 45.11 litres in there. Just over 45 litres works out a fraction short of 10 gallons - Giving me a run of 25mph - Not bad for a 5 litre car!
Interesting guys.... I was told last summer that my fuel consumption would be better by all of 2 - 3 miles per gallon as per Lloyd Developments when I had the new Canems ECU unit fitted and remapped. I have no idea what I was getting before hand. Coming down from Blackpool last week, was a good run, the motorway was quiet and mainly sticking to lanes 1 and 2 - due to having the respray only two weeks before hand and the paint was described as 'soft' and needs another two to three weeks to properly harden - therefore it was mostly 60 / 70mph all the way down. Yeah, I think we're be lucky to get better figures beyond 25mpg for the old five litre! After all the engine is now 20 years old!
When I first drove my griff home from David Hendry cars managed 278 miles on a tank can't remember how much it was to fill 11yrs ago but I seem to remember 29 mpg was what it worked out at mind you it was raining a lot of the time so roof on and bricking it as previous car was a Alfa 145 cloverleaf bit of a difference .

Average of 20 mpg over 2000 mls with my Griff 4.0 HC .
25 mpg seems quite unreachable, and it's not that I race it.
But never did a long trip.
My Tuscan was more economical....(petrolwise...)

Interesting guys..... Am I getting a vibes from this thread that the 500 is more economical than the 400?? I put it to you.......25 mpg seems quite unreachable, and it's not that I race it.

This is gonna open up a whole can of worms!!

Not sure if you mean pre-cat Griff 400 or 400 in general... But I've been tracking my fuel with Fuelly.com to see if I can ever hit that 30mpg I've read about.
Just a little game I play,but also if there is a sudden change in the figure then it can maybe lead to the fact there is a problem brewing.
Best I've had so far 27.51 (263 miles) 80% motorway at speeds 65-75 apart from a hold up for 40 mins stop start 0-40.
Av over 12,171 is 22.5 with the journeys I travel,but had many 25's and a few 27's on the 58 tanks I fill until the cut off point. Pretty sure without that hold up for 40mins I would of hit the 30mpg
It's here if you want to take a peek.

Change the diff ration to ether a 3.23 or 3.08 and you will see a big difference .Just a little game I play,but also if there is a sudden change in the figure then it can maybe lead to the fact there is a problem brewing.

I wouldn't know how to....
What would I loose by doing this,a bit of top end speed? How do I know what I've got now?
I just put the average being low because of the many shortish journeys I do added to the routes I drive + feathering the throttle to get pops and bangs doesn't help (But it's worth it
)
If you remember Daz I'm also no good with my handful of spanners if these are needed to alter it.
EDITED
Fook that for a game of soldiers.... I've just googled it
But thanks for the suggestion Daz

First trip after collecting my 500 from TVR-MADS:
Mileage at TVR-MADS = 26871
Mileage at Leatherhead =27110
Distance travelled = 239 miles
Fuel = 35.34l (7.77 gallons)
Gives 30.75mpg !
OK, there were a lot of roadworks on the M1 and I was keeping company with a mate driving my 1.9 TDi A6 so very steady pace. However, it's fitted with the Torqueflow TF500 induction kit and is a lot happier at lower revs than other Griffs I've had, 30mpg not typical but noticeably more economical than my other two 500s.
