Large oil capacity sumps

I was surprised to see that the latest Detroit DD13 and DD15 engines hold 40 and 45 litres of oil respectively. I would have thought that would have taken a long time to come up to temperature and I would hate to see the service bill for an oil change.

Would it not make sense to run a dry sump? Surely a scavenge pump wouldn't add too much complication?

i personaly think a high capacity sump is a good thing as lots of oil means better cooling for engine parts , oil will transfere heat away , obviosly a oil cooler would help , i think most big bangas need 2 x 20 liter drums of oil for a service

my little 6V53 holds 30 liters, giveor take a few leaks

What, 30 litres in a 6/53. Old 160 only 15 litres :'(

Cummins didn't plan for as many leaks! Lol

Ah Ha, is that why the oll Brennan put a catch tank under the battery box with a tap on it, perhaps I can use recyled oil

Cummins i have here, one is 35 the other is 39.

Now you know why there was a few drums in the Dodge cab Gillyman...
The Big Fella probably thought she'd be empty by the time she got down here...

The isx cummins take 42 to 48 depending if they are in an areodyne or a bonnet, C15 cats take 38. The new detroits are running the services out to 40000km instead of 20000km so they will be cheaper to service in theory.

Thats stretching them out Paul..
How times have changed, i only run the ol girls to 10000 max.

Found broken speedo cables was a good way to extend oil change intervals......

To really know when the oil needs changing depends on a few factors however, the best way is to get an oil analysis done every oil change and record the Km's and or engine hours and after a few oil changes, you will notice a trend.You then can alter the engine hours/Km according to the pattern of use and oil sample properties.

For $25-$30, Money well spent. I've had a couple of examples where fuel was making its way into the sump and the oil analysis picked this up and upon further investigation, it was found that one of the injector 'O' rings had failed.

I recommend oil samples for a good piece of mind.
