The main thing is the viscosity and the grade. The newer engines like the lighter synthetic blend 10W-30.
The synthetic blend is durable and the lighter oil flows well.
DD13 recommended oil

Stupid question, how much does a DD15 take when changing oil.
I am in Australia, so not sure if a DD15 is different out here, but the detroit parts store said 45 litres, google says around 45 litres, but all the mechanics I speak to say 38 litres.
The problem is, my engine has 2 dipsticks and they contradict each other lol, when u put 38 litres in one dipstick is over the full line and the other is well below.
45 litres and both are way overAnother Canadian driver Thanks this. -
Mine took 40 litres to get to the full line. If I bought two 20 litre Canadian pails it was right on the line. If I bought two 5 gal (18.9 litre) US pails I had to add two more litres to get to the full line.
Both cases with a new filter after running for 90 seconds and letting it sit for five minutes.Another Canadian driver Thanks this. -
If you have an intact dpf system you want low ash oil. That's where the dpf clogs come from.
uncleal13 Thanks this. -
Oil capacity seems to vary on most engines. Probably different oil pans based on application. Front vs rear sump, deep/shallow pan etc.
-
Yeah I think mine must be different as it's cab over, probably a different sump so you can drop it out or something, must be different to a bonnet truck.
Doesn't make it easy when there is two dipsticks that are different lol. I think I am just going to put 40litres in go from there.
