60 MPG over 175 miles is possible.. Well nearly!

It's very odd that you'd say that when I've posted evidence and others seem to corroborate my claims.

I shall post again with more evidence when I've bettered 60.1 MPG - I reckon on the right day the car can do better than that. An indicated 63-ish MPG would mean an actual 60 MPG, which is my goal.

Well you've inspired me with your 61mpg mate - just bought a 4 wheel alignment on Groupon - see if that makes a difference on top of my 160 remap, new Bosch maf and full service including pcv ... none of which have made a blind bit of difference lol

Good work!

Once that's all done, check your tyre pressures as well because they will have a drastic effect on fuel comsumption.

Let us know how you get on :-)

Just about all of the trip was on a flat motorway with very little traffic. I set the cruise to 70 and just let it do its thing. As soon as I returned home in mid-afternoon, I filled up at the same pump at the same garage. It equated to just about 60 MPG.

As I said, this was the only time I have ever checked it as basically I don't care what it does to the gallon. The opportunity just presented itself.

I don't know what others do to the gallon, I just know that on that day, with the milage that my odometer clocked, and the fuel it used equated to 60 MPG. Bear in mind, it was not a very scientific test.

Not scientific at all I'm afraid - when the nozzle clicked as you filled up the second time the tank may not have been full, and that would have given you an optimistic fuel consumption figure.

Under normal driving conditions manuals peak at around the 50 mpg mark, and autos considerably lower.

You can of course easily make the display show anything you want .

I always check mpg when I fill brim to brim. You can not do a fuel consumption check any other way. Also if you do a fuel check in the winter, it will be different than exactly the same distance and route covered during the summer. The best way is to buy your fuel on a cold day, and use it on a warm day!!??? I have done the same journey on the same time of day (traffic is usually the same at certain times of day)same route, in both cold,very, and during the summer. 144 miles to Somerset. During the summer, I have got, two up,half a boot full of luggage, and got 51.7 mpg. Same journey, under the same conditions as above, during a very cold spell, when we got there, the fbh was still running so had been working all the way for 144 miles, sometimes it must have been in idle mode, and the fuel consumption was down to 47.6 mpg. It was slightly warmer on the way back, and the mpg was 50.1. Read into that what you like.

I have no display on my car. It was calculated by mileage and fuel used. It equated to 60 mpg.

I am not suggesting that it averages that all the time over several thousand miles. On that run, with the conditions on that day it achieved 60 mpg. Facts are facts !

Of course it was just a fill up to fill up fuel measurement, with mileage from the odometer. So, no not very scientific, but I have no desire to go to those lengths to prove something that I don't really care about anyway. I just find it a bit strange that quite a number of people want to dis others off, and say it's not possible. When there are a few of us who have very similar figures.

[FLYING BANANA]

Just completed a round trip of 358 miles in my ZTT and averaged 21 mpg. Pretty good for a "kit ca" V8 400. No digital readout but worked out the mpg, with pen and paper, between refills.

I think you have hit the nail on it's head. It does seem that some are confusing average mpg with what can be achieved on a single run in all the right conditions.

Yeah I do check them quite regular - seem to lose a little pressure from rear offside over time. The recommended psi seems low for such a heavy car ...

[Heddy]

Only mpg I'm interested in is of course...average. If that wasn't the case I could strip out the rear seats, take up the carpet, in fact remove all the interior, remove the spare wheel, mirrors, wipers, etc and tape up all the doors! keep it real eh?
