BPU Mpg

Right i think im averaging about 18mpg with my BPU spec Supra at 1bar. I've basically spent £80 on Optimax this month at 95p a litre to do approx 350 miles on mostly a road 60-70mph driving.

 

Does this sound right?? 80 squid to do 350 miles?

i'm such a tight arse i only stick £20s in a go. Less painfull on the wallet !

 

Theres no way i get 87.5 miles on £20 !

 

psychologically i think by only putting £20 in, the car weights less therefore i should get more mileage out of her. but in reality you use more fuel driving around looking for a poxy petrol station !

On my last fillup it worked out at just under 18mpg. For some reason it doesn't seem to make any difference whether its citiy driving or motorway.

 

Will give the o2 sensor a clean and see if that helps, if not then I might just go ahead and replace it.

sounds about right for mine

just took a trip to Oban yesterday - got back today...round trip was 335 miles

had a 1/4 tank...topped up with £51 then £26....and just got back with a 1/4 tank

that was with both sensible and spirited driving :innocent:

Consistantly boosting second turbo = ~190 per tank

Driving pleasantly below 4k revs on motorway = ~290 per tank.

 

Wide spread isn't it! Mines stock with cats in though. Interesting to note difference with a BPU, but it's not huge as far as I can see.

You know what? I'm going to make a cd of the second turbo sound and listen to it while doing below 4k:limp:

that's a lot better than i'm gettin and i'm only stock boost! think some sensor cleanin might be in order for me! although i do have a heavy foot :D

 

I would definitely get a new oxygen sensor and then get the AFR's checked - Best thing I've ever done! I don't have any stats but Fuel economy improved bigtime! I reckon it paid for itself in few weeks.

Sorry to reopen this old thread but managed an average 26 mpg this week. Did 309 miles on £50.

 

Admittedly, 160 of those miles were done at 70mph with my sisters BMW barge sat behind us but still a good result, I think.
