This is my 2nd oil change. I dumped the factory fill at 1500 miles and replaced it with a non Dexos 2 HDEO oil. This is M1 Delvac ESP, previous PAO/Ester based CJ-4 formula.

Oil has 5,000 miles on it. Iím going to shorten my cold start warm up time from 5-10 minutes to 3-5 minutes to try and improve the fuel dilution. This engine only has 6500 miles at the time of this sample, so the rings may not be fully seated as well. I don't know yet.

Sample was collected hot from the drain. For accuracy, I took a composite UO sample, meaning that I filled up a 1 gallon jug, shook it up, then filled the sample bottle.

Also worth noting that for the last 3k miles I've fueled exclusively with HVO from Propel.

What do you guys think ?

3-5 minutes is still a long warm up time, I'd cut it back to 1-2 minutes or less if possible and drive slowly. Aside from that the engine is still breaking in.

The engine too new for a uoa to tell anything except the metals are a bit higher from break in.

These metals readings, especially the iron, are actually much lower than the few reports I've seen on this new engine, from people with higher mileage. They are using Dexos 2 oils however, and I am not.

Where do you live in California where you need to idle to warm up? The mountains or high desert?

Northern California. It is around 30 degrees F right now. I warm it up mostly to heat/cool the cab and reduce the oil pressure. Start up pressure is usually 65-70 PSI at idle, even when it's warm outside it's still really high with this oil.

The purpose of the early oil change was to see how this engine handled a non spec oil and to get a baseline. Now I know about the fuel dilution which is occurring and can make some changes to my cold start routine. If I can get the fuel dilution under control see going 10k + on this oil as there is still lots of life left.

30F isn't really that cold. We have cold starts in my neighbourhood of down to -40F or -40C. Let it idle for a minute, and you are good to go with no more than 30% throttle until it starts to warm up. I had 1,000s of lighter duty diesels in my fleet and most got handled pretty roughly. And we kept them in service over 10 years. Oil related breakdowns were not an issue.

Just to clarify, engines and especially diesels warm up faster under load. That's why I recommend: start it, idle for a minute and then drive. Idling for a newer diesel engine with DPF and new emissions controls is a bad thing. Avoid idling as much as possible.
Our fleet had GPS trackers that flagged any idling over 3 minutes. Bad for the engine, bad for the environment and bad for the pocket book. And if you include all of our North American fleet - talking 20,000 trucks.

why do you need to reduce the oil pressure?

Stop the idling. These engines warm up so much faster under load.

Report looks good. FD not a huge surprise on an emissions diesel.

Beware that many manufacturers use a fake oil pressure gauge that shows a programmed reading based on rpm and engine temperature.

don't let it idle that long. You may just need a minute at the most and then run it. I think 3 minutes is too much for a modern engine

Don't diesels come with an idiot light for warm ups? As far as I know, as long as the glow plug light is off, I'm driving it. I'd idle that thing a few minutes after long loaded runs (hwy or what not) for the turbo to cool though.
Besides,
