The mechanical pumps should be perfectly capable of no fuel when on overrun - fuelling is a function of engine speed and pedal position. The old K-Jetronic petrol systems that used electronic idle control would switch off the injectors on overrun.
I managed over 800miles on a tank completely by accident when moving house. It was almost all motorway mileage at around 70mph, half with a completely empty car towing my empty single axle trailer, the other half with the car and trailer stocked to the gills. The light came on at 750 miles, and I know I could have pushed to well over 800 if I didn't have to turn around and do another 150 miles!
I also managed to squeeze 72 litres into my tank once, and queried it with the garage owner. The pump was within allowable tolerance, apparently
Could you get 1000 miles to a tank in a Xantia?

I'd like to correct the 3-400 miles on a tank I mentioned before, that was in Jim's 2.1TD where I was getting about 30mpg.
Cassy is coming up on 550miles of 100% veg and a bottle of Redex Boost, and that's with a trip down to Portsmouth and back doing 90+ for most of it, and hurtling around MK (too many roundabouts) getting up to 70mph between each one on the dual carriageways.

Well I have got 57mpg average on a 110HDi saloon, that would get me 878 miles on 70 litres.
I can easily believe the tank is larger than the claimed 65 litres as an indicated half tank took 40litres of fuel.
However - if you're driving an HDi - isn't there an argument that running the tank low overheats the in-tank pump leading to premature failure?
Shame that the most economical engine has this achilles heel!

A 2.1 should be better than a 1.9, much more efficient engine, my XM will top 50 mpg and its heavier - unless yours is auto.Xac wrote:I'd like to correct the 3-400 miles on a tank I mentioned before, that was in Jim's 2.1TD where I was getting about 30mpg.

Re tank capacity - my last fill was 64.46 litres, and I was barely halfway into the red zone. Car ran comfortably with no carrying on under hard acceleration or uphill. (Cost of this quantity in premium unleaded was $105.01, or GBP£46.67)
I filled at the bowser where I'd seen a Gov't "weights and measures" guy doing a random check the week prior.

It is with me Peter My 2.1TD is so frugal that when the rare occassion arises that fuel is needed, I firstly need to determine which side of the car the filler is and then take a few moments to study the pump operating instructions Cobwebs grow across the filler cap...Peter.N. wrote:A 2.1 should be better than a 1.9, much more efficient engine, my XM will top 50 mpg and its heavier - unless yours is auto.Xac wrote:I'd like to correct the 3-400 miles on a tank I mentioned before, that was in Jim's 2.1TD where I was getting about 30mpg.
