Fuel notification

Post by Dogfuzz » Wed Jun 12, 2019 10:19 am

Filled up on Monday and the indicator read that I had 426 miles till the next fill up. Today was passing a cheap('ish) petrol place and since I had time, thought I would top up to the top again. Noted before top up that my gauge was reading that I had 379 miles to go.
Tank took another £7 to fill to brim--but when I switched on ignition and drove off forecourt, the gauge was still reading 379......
Does this gauge have a mind of its own?

I find that unless you're putting in a reasonable quantity of fuel the gauge and range don't change immediately. I've had this mostly on courtesey cars which you invariably only want to but in a few litres before returning. And eveyone of them (which were not Mazdas) did not register the fuel.
Did the range eventually register the additional fuel?

It’s no different than most cars, the fuel gauge doesn’t move for 50 miles or so. The tank unit is in the top of the tank so it has to use what is in the filler pipe before it starts falling/changing.
