OIL REPORT?

[CLIPPERS]

Blackstone did an oil report for me & it reads as follows: Fuel was found at 2.5% in the first sample from your PSD. This level is just into are cautionary range and may indicate a fuel system problem developing. As this is the first sample that we've seen from your 6.0 we're hesitant to make that call but we'll keep an eye on it next time. No other contaminates were found and wear looks great so the fuel hasn't affected anything.-------------I usually only drive short distances from work & home ( 4-5 miles). Could the fuel in the oil be from that? Or where else? The report was done with 5300 miles on the oil. The truck has just under 60,000 miles on it. THANKS!!!

Yes, short distance driving will do exactly that. Its fuel that passes by the rings when they aren't hot enough to seat. Try to put more highway miles on it this time!
2.5% of 15 guarts is 12 oz. if my math is right. 12 oz. of fuel is too much to be good. Your rings don't seat good untill you get to full operating temp and that takes 5-6 miles of driving on a cool fall morning.
One other thing you can do, and I have heard of alot of guys doing it, is after that first half mile driving, get on it hard for the next mile, that brings those temps up really fast and seats the rings faster.

I live in North Missouri, and some mornings it takes 3 to 4 miles to warm up.

I have the same problem. I have been doing changes at 3k to keep it from causing damage. My travel is almost all highway and I never let it idle. I would love for someone on here (or the dealer) to say it's something other than idling and city driving. I even tried the high idle mod to let it warm up and no change to the fuel in oil level.

How about a remote starter and let that puppy warm up a notch or two before taking off ?

5 miles is way too short of a run for a diesel. If you must put your miles on 5 or 6 at a time then you need to shorten up the oil change intervals. 5300 miles is already a stretch on the oil change under good conditions. Most techs that fix these things on a daily basis will tell you no more than 4000 miles.

I had them do a TBN, and they said the oil had alot of life still in it and to try a 6500 mile oil change the next time? I would like to let it warm up before I drive it, but I'm told you shouldn't let them idle too long either?

What kind of damage can happen with 2.5% fuel in the oil at 5300 miles? If I go longer between oil changes won't the percentage go up?

Iwould think so.Are you running a chip? I noticed when I changed the oil in my trk last service it smelled fuely, maybe could be from that?

Definitely - give it some time to warm up at idle, when very little fuel is getting shot into the cylinders. Or use the block heater if it's very cold outside.

An engineer gave me a rundown on why driving a cold engine is hard on it. The parts tend to expand at slightly different rates. The quicker it warms up, the more the parts expand at their individual rates, causing pieces to move that don't normally move. This is particularly pronounced on engines that have aluminum heads and iron blocks, but it's true of any engine.
