Which equates to 10,000 kilometres !old'uns wrote:looks as though 6214 is the limit on option 1?


Which is exactly what I do every refill actually (for years), but since the car computer counts the miles (km) passed, and knows how many gallons (litres) have passed by, I guess it can't fail in a simple math division operation to get the total average (which is correct in my case, compared to my math)... approximates for the remaining tank are a different matter however and usually linked with the weight of a drivers foot ...carman wrote:can you trust the computer read out, best way to check, fill the tank, zero the reading ,do this about 4 times ,then take an average
