Looking To Double Check For Correct Dipstick.

I just bought my first Mack, a 77 DM686. Got it cheap, and it is an oil burner. I checked the dipstick, and it was dry. Added 2.5 gallons, and nothing. Fires right up, runs strong, and the last owner even drove it over for delivery. I know the engine probably holds more than a dozen gallons, so I might still be low.

I would like to find the correct length of the dipstick should be, so I dont overfill. And, what are the specs for engine oil capacity?

Last owner said this truck would burn 4 gallons in 8 hours, running the highway, working hard. I know gas engines fair, and blowby would pressurize the bottom end, etc. But, this truck seems to be strong still. As it warms up, it gets better, but never goes away. Is it just wore out?

Thanks for any help.

32 litre or quarts total 28 in the pan. If it has 3 oil filters (Deep pan ) it takes 48 in the pan 53 including filters

The endless oil change your doing a n oil change every second day!

The E-6 had two oil pans, a deep (say, fourteen inches deep) and a shallow ( say, nine inches deep). It is possible you have a shallow pan stick in a deep pan. Let me know what you have and I'll send you the correct stick free of charge.

Phil, thanks for the help. The dipstick is 24 5/8 long, hooking the tape on the bell that acts as a dust boot and seal. I did not measure total distance with the T handle. The pan is 9 inches deep. Maybe everything is correct? I don't want you to just send a dipstick if I have the correct one. Other than that, I really appreciate the offer.

fjh, thanks for the help. I have the shallow pan. No kidding on the endless oil change. I bought it knowing that, and only use it occasionally, or it would bankrupt me... Ever heard of one using that much oil?
