630+ miles to a tank - LCR
- Thread starter speedinsaxo
- Start date
I brimmed the tank last Thursday, and did a run to Penrith and back, when full the trip said 415 miles, but with an indicated 10 miles left in tank I've done 335 miles, none of them hard and not exceeding 80 mph at any point,
The car did have a bike rack and two bikes on which obviously hindered it but I don't think I could have got any more.
Iv a trip to heathrow soon, 400 mile round trip, will see how it fairs

also lots of different factors that can effect MPG: weight, tyre pressure, fuel types etc etc
be good to see what the best you can get from it is ?

ah well this is where you went wrong.
the range is based on recent driving only. litterally the last few miles.
so if you went for a steady drive on the motorway then slowed down and stopped it would base the range on the last few miles of motorway driving only including slowing down and so the indication that you can get another 515 simply isnt possible.
What you have done is basically cherry pick a small part of the journey. - Next time you go for a drive let me know what the range is indicating after a few miles..
If you dont believe me try taking it easy for the whole tank and see how many miles you actually end up doing.

I disagree. The range was showing around 500 for approximately the last 1/4 of the journey. I just wasn't going to take a picture whilst I was moving. When I was on the motorway it was showing 520 miles. When I was in a safe place ot take a photo it was 515.
I will admit that getting over 600 miles to the tank seems impossible. One day I will see what the limit is. What really effects the mpg is stopping, letting the enging cool and starting again. If you were to do one journey on a full tank I believe 600 miles is possible. It is just not a very practical scenario. My average to tank from mixed driving (but quite a number of stop/starts) is about 380.
really.. noone is gonna tell him whats going on with his car?
Hey sax guy; your trip computer will always over read when you have a chipped car. Same as my Pajero where my range went from 600km to 1000km after chip install. Read you REVO manual.

Interesting
I recently checked my LCR's 'real MPG' vs the trip computer's average MPG: filled up, did a 112-mile trip (some A/B roads, then mostly motorway and dual-carriageways) and at journey's end the trip was showing an average of 29mpg. At which point, I also re-filled the tank and calculated mileage-divided-by-gallons-consumed. Result? 29mpg.
So, in the instance above, how can the computer's average MPG be "based on recent driving only. litterally the last few miles"?
Just askin'

What type/brand of fuel have you used since you bought your car - the same brand more or less consistently, or a variety?

i agree, however thats not what i said
- i said the RANGE displayed is based on recent few miles.The range is therefor saying you will do this many miles if you keep driving like you have recently.
The mpg is based on longer term, something like 300 hours or 1500 miles.. something like that

That's intriguing, because Willy's owned his LCR from new and always used Optimax/V-Power, and in the past he's commented that he's often able to achieve 40+mpg.
It would seem, therefore, that Optimax/V-Power's alleged cleaning properties actually work?
I mention this because I'm beginning to suspect that LCR injectors are prone to partial clogging/fouling if run on any old type of fuel, which may explain why some LCRs are currently not getting the MPG they used to achieve?
Also noted that Evo mag ran a new Mk1 LCR as a long-termer in '03. And the test's average MPG was approx 29. So, considering it was thrashed/driven by a bunch of lead-footed hacks who don't pay for their petrol, a 29mpg average is pretty impressive.
Obviously Evo's car was brand new, but it also had squeaky-clean injectors...

The mpg is not based on 300 hours or 1500 miles! It is what you are currently achieving since reset. If you leave the car longer thatn 2 hours without driving it will reset.

Certainely does not seem to have done it any harm...
there are two mpg figures.
one for current journey and the other is as i said, which is what you would use to see overall mpg for a tankful of fuel

On my car one is instantaneous - i.e. wildly changes if you put your foot down and goes to infinity if you coast in gear.
The other as I said is not over the tankful, it is for the journey and resets after two hours of non driving, so when you start the car it is around 16mpg and climbs to a higher number the more you drive - in my case here 44.7.
