Hi, I have a diesel 306 - its done 127:000miles I'm having problems working out whether or not I'm getting good miles per gallon.
I put £10 worth of diesel in at a time until the light comes on (approx 12 litres ) and I am getting about 90 miles from this. Is this good / bad? If its bad:- Whats causing this? How can I improve this?
It's easier to fill the tank all the way up, drive around for a few days, then fill up the tank all the way up again. That way it will tell you excatly how much fuel you used to to X number of miles (and you don't run the risk of running out either). The more miles you do the better the average.
If you want to check it properly, fill it up to the brim and reset the trip meter, use it for a week and then refil and not miles and litres. Bit more accurate. Dont know about you but when I fill when the light comes on permanent on my car it can have as much as 3 litres variation week to week.
I don't think tuning a diesel will give more miles, (if you can tune a diesel) what exactly will they do? I've changed the fuel filter,oil filter, oil, what more on a diesel can you do?
Yeah Ive considered that, maybe I'll check the haynes manual to see how much the tanks holds. Not sure if this is true but I was once told these diesels do a 100 miles from the light coming on to empty tank.
Not too bad - I tend to get 110-120 miles per tenner depending on how I drive. Fast mway gave more like 100. After current posts on timing being one tooth out I'm more worried about that, top speed (err, private road) seems to be about 105mph.
