Best MPG so far

Post by Skyrimmer » Fri Jun 15, 2018 7:30 pm

After spending 3 days since I got my Sri 1.6t 200 seeing how fast I could go, I decided a better game was how high could I get my MPG to display.
On a run from Norwich to Great Yarmouth and back I managed to break the 50mpg mark, mainly on dual carriageway. That seems quite good to me but as I did not have a trip computer on my Astra GTC 1.4t I cannot make a comparison.

With fast motorway work (mid seventies), over 230 miles or so, I get 50 mpg from my 1.6 petrol turbo - measured brim to brim - how do they do that?

The best I've had was 70mpg on b roads during a 20 mile trip. I've now averaged 65mpg over the duration of over 1500 miles (mixed driving).
With my 1.6d (136). Also running with 16" Mich energy saver tyres. It's an auto too.

From Stoke to Liverpool on the M6 through the 50mph roadworks 75.9 mpg but it was a clear run with no traffic. It was creeping up till the return journey when I was queueing and it dropped. 1.6 (136) Elite ST manual.

Reckon I can get better still on a longer run.

If all onboard computers are as accurate as mine then they over read by about 15%

I recently did a couple of long journeys with some steady driving so brimmed the tank at each end of the trips. I got an actual 46mpg (51.5mpg on the trip computer) at around 70mph and in general use with a mixture of driving we get about 37mpg (42.5mpg on the trip computer).

The best ive got running 98oct in a 1.6t manual on the hwy which was reasonably flat at a constant 95kmph with 4 in the car is 4.5 litres per 100km.

A quick check shows this is about 52mpg in us terms or 62 mpg in imperial.

3.9 lt/100 km with manual 1.6 CDTI 136, AC on and auto on 24 degrees for a 425 km journey. Fixed the speed to 108 km/h using cruise control.

As an add on to my last comment, the last tank has just done a rather disappointing real 30.5mpg after doing lots of short journeys although in fairly light traffic and it's not really been hooned around.
