Does this look okay to you? Cummins ISB 6.7 oil level?

The B engine is always confused by techs for the proper oil amount. For one there are two different capacity pans available for the engine. My guys accidentally overfill this engine all the time mistaking it for the bigger C or L engine. Not hard to do with a oil pump and meter. Not really an excuse for leaving it overfull though.

You better have your ducks in a row before pointing fingers about not completing the oil change intentionally. If you do, I would plan on not going back to the service location regardless.

Correct the level and move on. Look at it this way depending on how much oil you were billed you might of got 2 extra free gallons. Put it in a spare jug for top offs or use it to change the oil in your lawn mower.

 

I can’t say much as I overfilled my own last week! 1 gallon. Not to worry it’s burning/ leaking at a good clip these days. Lol 3600 miles still full.

 

Sometimes when doing an oil change and then running the engine and not giving the engine adequate off time to drain back all the oil from the top end can cause someone to think it is low and add more oil than needed.
When changing the oil in my Detroit there can be as much as a couple of quarts difference between checking it right after shut done and waiting 15 minuets to check it.
I read somewhere in my Detroit engine Manuel that they ask you to wait 15 minuets after shutdown to get an accurate oil stick reading.

 

This is why you should always do a oil change service on a warm engine. 1- more of the old oil comes out at draining. 2- the new oil is warm when installed and will drain back quicker than on a cold engine for accurate final measurement. Lighter wet oils help but the theory still applies.

Take 10w30 outside to 10*f overnight and see how quick it pours. Thick as can be.

 

I remember the first Caterpillar I drove had markings on both sides of the dip stick. One side was for normal pretrip and the other side was to check it when running. You don't see that anymore!!

 

Yes you should drain oil when warm but only after it has set for 15 to 30 minutes.
I also witness guys pulling in to the fuel isle and shove a nozzle in the tank and then throw the hood up and check the oil.
All this done in about five minutes.
There’s no way that oil level will be accurate in 5 minutes time.

 

Better to check in the morning before you even turn the key. Though fueling is a reminder for me to check the level, at least on my personal vehicles anyhow. The towels are right there, plus I gotta wait for the nozzle to click anyway=might as well do something productive. Never see anyone even checking anymore. It's amazing theres not shops that specializes in frozen hood latches.

 

People would know how to open the hood if the USB port was by the dipstick. Just sayin'.

 

Believe it or not I check mine in the morning and every fuel stop.
This is how I know there can be vast differences in oil levels from completely drained back in the pan in the morning and not letting it sit long enough before checking it at the fuel pump.
Hey I think I just figured out why all these clowns keep parking in the fuel isle.
There waiting for there oil to completely drain back in to the pan so they can get an accurate oil level lol.

 

best time to check is in morning before start. all the oil will be in the pan. anyhow, judging by the looks, its double filled. they never drained the oil before adding. probably didnt even put a new filter on. you better drain that pan quick. way too much oil in there
