Show Us Your Mpg's

[RossISF]

I find MPG's can be alot of talk, so I was thinking today after a long spin I should take a photo of my MPGs and post um with the idea of other doing the same. Remembered the figures but forgot the pic!

I have been known to have a heavy shoe, but my current figures were 17.4mpg avg and tank avg of 22.

I will get the pic up tomorrow, I read originally they can do between 24-30mpg ive never seen anything avg above 19.

Look forward to yer inputs

My long term average is about 26.5, I've had tank averages upto around 32. But I do a lot of motorway miles which makes a big difference.

I averaged 24.7mpg over 36,000 miles.

Its not to difficult if you don't use the brakes. Mine were still on the original pads and discs with plenty or wearl eft when I sold it last week

This was from a journey that started on a full tank to the point you can see on the gauge.

My best has actually been 36.1 mpg over 125 miles, all with super unleaded (which helps)!

[Womble72]

Best I've had is 35mpg, but the norm is tank average of around 19.8 mpg, BUT I don't tend to do many runs in mine, I'll do a London run about once in 2 weeks, other than that it's only local runs, London run will get her to about 22 mpg, I also had as low as 5.9 mpg

[JonP]

I agree with the super unleaded improving MPG. I've been experimenting with different blends and the Shell Nitro seems to give me the best mileage. It's really noticeable when I have to fill up with low octane fuel and it usually takes a couple of tanks of super to get the mpg back up. I presume because the ECU is slower to react to the better fuel.

I have had as high as late 34 on a motorway run and as low as 16 on a spirited drive. Think my current average is around 24mpg. Impressive for big v8.

[MNMJ]

Yes definitely; Shell Optimax and then Nitro plus was the almost exclusive diet of my IS-F. I'm now looking forward to flushing some through the RC-F and reaping the performance and mpg benefits

I use BP Ultimax.. and when drove from brum to bluewater (lexus meet up) i averaged 32mpg.. this was a 340mile round trip.

I put in £65 of feul.. which tbh is the best i have got in any of my previous owned sports cars.. better then my CLK55 and M3.

[RossISF]

Interesting. Wud love to hit the 30s some day. My tank avg at the momnet is 22mpg live figures below after a so called spirited drive!

[VamboMan]

Currently run mine on Shell Nitro as fuel prices are very low compared with what they were a year or so ago. Not certain whether it makes any difference to the MPG but it should keep the engine cleaner so maybe it does improve MPG. Done 31,000 miles in mine and always in Sport mode and have averaged 28.8 during this time. Rural living and a very early commute to work helps as there's very little need for constant braking and accelerating.

About 24mpg here. It's been as high as 33-34ish on a long motorway journey. Most of my driving is town and hoon (not much in between)

[DAW]

I've only done 3500 miles to date all on high octane, but my tank average is usually around 26. The best was 33.7 which was on my journey home from Leeds after picking the car up.

[Dar]

I do a lot of driving on the outskirts of central London and some motorway driving and average about 20. Most I've seen cruising at motorway speeds was 34! My wife did get it down to 15mpg after she drove it for an hr or so - she thinks manual+sport mode is how it should be driven and I kinda agree! It's my daily drive so I can't hoon around daily!

[lotusdave]

My average since I had the car, 20,000 miles or so is 26. My track day had a tank average of 9 if I recall.

I regularly see 30 on a motorway schelp to and from clients but also a lot less if I can find a good A or B road or some roundabouts.

It's horrific in traffic but I try hard not to look.

So about the same as a golf diesel then?

669 mile round trip this weekend, I managed 29.9mpg, which I'm happy with 👍
