How long does your 12V oil stay "honey colored"
I changed the oil on my 96 the other day. It currently has 284k on it.
About 500 miles ago I had the block & head fire ringed in chassis and installed 181 dvs (in the 160 pump that is on it, the 215 was getting tuned) ddp stage 3's, 3 piece htt manifold and a HTT Quick Diesel 64.
I ran about 150 miles after the oil change and figured I'd check the oil level to make sure it was still OK. I used a white napkin to wipe it off and re-dipped to check the level and all was well, so I closed the hood.
I got to looking at the napkin and it wasn't even BLACK.. just a light gray-golden color. I was like WTH.. this isn't right. So I opened the hood, pulled the stick and sure enough the oil is still a clean honey-color.
I just put another hard 300 towing miles on the truck and it is still clean.
Crazy considering the fuel I have (soot) running in this truck and the miles..
MY 98's oil is PITCH black right after startup on a fresh oil change, and it only had 225k miless on it!

Well Im not to sure what to say about the 12'er. But I know on one of our 99 F-250 with a 7.3 PSD (290,000 Miles) I can run it a full 1200 miles checked the oil level and it was still nice and clean, even on a white towel.
But any other truck around here even my 01 PSD with 59,000 miles will turn dead black after the first 25 miles, that goes for my 24V, and a few other OTR trucks around here with low miles. Its all the same oil in every truck Cenex Super TMS 15W40.... Wish I knew the answer..

Same here: my 06 5.9 and my 6.5L tool van black in 60 seconds. my 210000 mi 12v stays clean for 1500 mi (what) I recently changed my org lift pump and it looked like it came off a 5000mi gasser.

if the truck was bone stock for a long time and you just cranked it up and you're running a stratapore filter, I could see it staying cleaner longer, but my 12v's have always been smokers, so the oil is black as soon as I pour it in

You should have looked at the valve train when they opened the head cover. CLEAN valvetrain.
I was used to gasser engines that after 50,000 miles are all "gunked up" .
My 1st 24valves with 243,000 was as clean as it can be, the next one (12v) same results.
I had a Chevy 6.5 once, change the oil, amber, start truck to run oil through motor for 1 minute, check oil.... BLACK, and so black it was staining the towel.
I love Cummins for this, I change oil at 5000/6000 miles and it's slightly darker then the one that replaces it, not much more. And ALL my trucks have over 150,000 miles by a long shot.

Mine is pitch black within a few minutes of idling it after the change, I think it might stay a little cleaner longer when I keep it in valet mode as opposed to full fuel.
