LML Dirty oil 300-400 miles after dealer service

i change my oil once every 12,000 miles or once a year... im a bad boy :roflmao:

No no, you’re just “special” nick lmao.


I’ve never had clean oil come out of my lb7.... stock, tuned, built nor as it is with the lly top end. You lb7 ladies must not drive them hard enough :rofl:

I agree james. Neither of my trucks lb7 or lbz have ever had clean oil during the oil change mine is changed either 7500 or olm minder message on dic. Trans spin on get changed every 5k regardless as well as fuel filter every 8k. Chevron delo 400 and mobile m1-303 filter here

I once flushed the oil in my LLY at around 110k, I used oil from the rig, I had to change it 5 times along with the filter to get it nice and golden, it lasted 1,000 miles, changed it at 3k and it was black again, never ****ed with it again.

My LMM has always been changed between 7-10k, it’s always black, even after change, when I pulled the motor and cleaned everything out, I’m at 1500 miles on this change and it’s still golden but I haven’t drove it hard.

Yep I have flushed my oil several times in a row just to see if I could get it so it wasn't so black. Still black in a few hundred miles.

Funny thing here is the 2 cups of oil left in the stock lower oil pan hasn't been mentioned. the 2 cups of dirty oil can make a fresh oil change look as though it wasn't even performed:thumb:

No worries here I must have missed it while reading the posts just making sure it was addressed. Justice brothers seems to make a good diesel emissions cleaner kit that goes in the oil and fuel and suspends the soot particles that dirty up the fresh oil seems to work. How long the oil stays clean is beyond me but when service is performed it works pretty quick.
