hey, this should be a quick one..can anyone tell me how big the fuel tank on my 78 300d is? i want to calculate my mileage. thanks!
that's a good idea, i'll give that a try the next few times i fill her uphere's what I do.. Fill it all the way, reset trip od... next time I fill it all the way, I divide total miles driven by gallons I just put in.. average this over a couple of tanks you and you should get a pretty accurate read. My tank holds 21 gallons, but I've NEVER been able to put that much in no matter how empty my gauge says I am. Not sure if the sedans had the same size tank as the coupe though...
