GR86 Real World MPG

[leosayer]

After around 3000 miles I'm averaging 33mpg with the 38 being the best got from a tank and 30 the worst.

Not much town driving, just b roads, a roads and motorways.

I got 38 a few weeks back from crawling along a very wet M1 at around 50 and 60 due to heavy rain.

Done a couple of proper MPG checks on my last couple of tanks (ie, filling to the first click then doing the arithmetic manually next time I fill up based on miles travelled). Tank before last, I did about 200 miles over motorway cruising, then the other 100 miles was just daily stuff and one proper Sunday morning drive, which is fairly typical use for me. Worked out about 33MPG over that tank. Did the same the other day, although this time the only driving had been daily short runs and a couple of Sunday morning drives (no regard for economy) and that tank worked out about 27MPG. Think the dash is currently shows 34MPG and that was reset a few months back. So fairly accurate and not bad at all.

Went to Mallory Park yesterday, a round trip of 220 miles for me. Brimmed it before I left, and then when I got back. 41 mpg actual. Very immpressed Not quite reached my 1000 miles, so wasn’t pushing it, but wasn’t hanging around. Last week done the same but on shorter trips, and achieved 29 mpg, so I guess 33-35 overall should be achievable going forward.

Reading to Guildford using A roads some local traffic, loads of roundabouts and short motorway : 42mpg.
Typical mixed route where I live. Total 60 miles return trip. As close to real life test it can get. I was always at max speed limit on all roads.

It would be useful if you guys said what fuel you're using

Tesco Momentum almost exclusively as it's nearly always the cheapest available premium fuel around here.

 

[Bluemanc100]

Does anybody know if the premium Costco fuel meets the grade?

We pass one pretty close to home that we tend to use at present

The pump will say what RON it is, right?

Yes.. They have 95 and 98.. I assume the 98 would be ok but I just wanted to ask what people’s opinions were as I know that supermarket fuel gets a bad rap and I assume Costco would come under that banner loosely speaking

I can't imagine it being any different to the main fuel brands. They have the same standards and regulations to meet and get it from the same refineries.

Yeah it does, its supposed to be good stuff actually. I wouldn't hesitate to go there if there was one near me.

That’s great news… it’s usually cheaper than regular stations though I’ve just got a veterans discount card for Esso that gives me about 6p off per litre so that’s my backup

c.2,000 miles and I'm low 30s mpg mixed driving, getting up to 40-42 mpg on steady runs.

My GT86 economy improved as I reached 10k miles. I once saw over 50mpg in a long, boring 60 mph cruise.

My experiences of Japanese cars (mine and partner's) is that they do get more economical with miles.

I'm exclusively using Shell V-Power as there's one or two Shells on my regular routes.



Edited to add - I've probably said all this on this same thread above, so forgive me if I'm repeating myself; I do this increasingly as I get older.

I use 97 octane Sainsbury’s super unleaded

 

[Triggaaar]

At my local station, the premium is 25p / litre more than std unleaded. That's a lot. If I can get a decent price at a supermarket, that's where I'll go. Otherwise I imagine I'll use standard.

I’ve just looked that up, had no idea it existed. Thanks!

I never knew that this existed either. I've just logged into my DDS account and ordered the card. Thanks for the inadvertent heads-up!

First long trip was a couple of ~110 mile journeys, car only a week and ~70miles young at the start. 70mph motorway almost throughout. It's hot so that always helps (though air-con counters a little, plus was two up, and boot full of junk for one of them), fill-to-fill shows averaged 42.6mpg (uk gallons) - something like 6.67litres/100km? Cue victor meldrew.

That’s impressive! About 800 miles in now and the average is showing at 33.5 but it’s steadily climbing. Even on the French autoroutes at 85mph the live MPG hovers between 33 - 36 which is really quite decent. Obviously goes down a lot when going up a hill etc. but I’m fairly happy with it.

Tank after (so should account for short/overfill of previous) was 38.15mpg (UK) over similar long journey, in torrential rain which will have sapped a bit but also top speeds a bit slower. So average over the two is just over 40mpg which I'm happy with. Suspect it's the summer effect and would expect much lower in winter. (Momentum99, no spoiler, [email protected])
