Question Oil change tips on DT466E

Am I crazy...? I searched "oil" in the search on this site, and it turned up with 0 posts. There must have been an error because I can't imagine nobody talking about oil.

I have an International 3800 with the DT466E. I bought the bus in early August. I just decided to check the oil and it was soo black. Like tar black. After digging around some of the paperwork that was in the bus, I found that the last oil change was done Jan of 2014
  • Does anyone know the oil capacity on these engines? I don't want it to overflow my oil catch when I change it.
  • Anyone have recommendations for oil brand/viscosity/synth or non-synth, etc. ?
  • What are your oil change intervals for the DT466?
  • Do you guys change the filter with every oil change?
  • Any other tips? I have done plenty of oil changes on cars & motorcycles in my life but for some reason the bus is a lot more intimidating...

The DT isnt any different than any other diesel.
15w40 Rotella or Delo
Change filter every oil change

Rule of thumb for an oil change is 1000 miles per gallon of oil. So, if its a 5 gal capacity....5000 miles. Of course this varies at times.

Like I always suggest, get a $25 oil sample done from Blackstone Labs and find out whats going on inside the engine before you find out the hard way. They can tell you if your oil is in need of change as well.

Fora don't like short one word searches. Try a google site search instead.

Oil capacity of a DT466 will fully depend on what oil pan it has. It can be 15 liters more in one bus from another.

Like has been said, 15/40. Brand don't matter.

Diesel oil contains detergents to break down the carbon buildup. Carbon is what makes your oil turn black.

Oil capacity has no reflection on changing interval. Time and mileage, which ever one comes first is what dictates oil change interval's.

At the shop where we keep 400 buses running, we change oil on regular rout buses every 20,000 km. On buses that fill in as spares, we change the oil every 6 month's, regardless of the mileage on the oil. This is due to condensation leading to water buildup in the oil.

So, get a big pail, crawl under your bus, drain the oil, pull the big a$$ filter, reference how much oil drained into the pail, go to the store buy the same amount of oil plus 2 liters, use the old filter to get the right new filter, go home, fill the new filter and spin it on the engine, replace the drain plug, fill the engine with oil.

Careful not to overfill the engine oil. This will lead to leaking seals.

When you think it's close to full, check the dipstick. When it reads full, start the engine for a few min to get the oil flowing, shut it down, check again.

Always warm the engine up to operating temp before draining the old oil.

Make sure to fill the new filter before installing it on the engine. Failure to do so will cause the engine to run for a few seconds with no oil pressure, damaging the engine.

Your engine may contain more than a single pail will hold.

I live, work, and breathe buses.

Glad I could help.

This. I use 2 buckets. One under the side drain and one under the bottom drain.

I don't know if two drains in the pan is common, but both my Cat CT13 and my Cummins CTA8.3 have them.

I have a good friend who is a diesel coach mechanic (and luckily who is happy to answer my questions - too bad he's in AK and my bus and I are in WI), and he advocates changing the oil every 2,000 miles, although they don't change the oil that frequently in the fleet he works on. His reasoning is that the bus will always run better on new, clean oil than on dirty oil, so change it as frequently as you can.

Nope......not a good idea. Too many reasons why and I'm not interested in taking the time to go in detail. Surely Google will though.
