My MY23 has a delayed gauge drop.
I brim the rank and the needle is right up at full
It stays there until about 90 to 100 miles has been done. It then starts to drop.
I zero the trip gauge when full and us the rule of thumb 250 miles range to refill. At this point the needle is on 1/4 mark and the low fuel warning shows soon after that. I was told that when this warning shows then there will be 70 miles of fuel left. I never tested that! I have gone down to 40 miles and the needle approaches zero.
I get upper 40's mpg average with occasional up to mid 50 when pootling along. Auto box and normal mode. We doo many high mileage trips, scotland twice last year....
The handbook says a tank capacity of 38litres so 8.37 UK gallons. At 45mpg that should give 376 miles...yeah , In your dreams!
If I push it to getting 300 miles ( 250+50) then at 45 mpg that's 30litres. So theoretically 8 litres left.
There are reports of the 38litres being a max and a "usable" volume of 33 litres, i.e. 5 litres base level above empty as the advised minimum( to keep the pump under fuel? ) Confusing!
My previous trads had 55litre tanks. The 1993 4/4 had a drain plug. During a fuel system maintenance I drained the tank, added 1gallon to check what the gauge showed on level ground. My safety reading!
So, the brim to 250 miles is my guide. An ICE variant of EV range anxiety but with easier refuelling.
Our Kia Sportage displays fuel data, mpg, miles of fuel left etc. Why can't an £80k car do that? It's a modern BMW engine after all.
GRRRR
