I agree. Also, it occurs to me that this community could be an incredible contribution to the work that Lake is doing. He repeatedly mentions in his videos that his purpose is to share knowledge (not just his) and use science not speculation to inform decisions. There is a scientific brain...

BA in advertising and a lifetime in racing with a family pedigree? Tough crowd here...

I love CAT equipment but it seems corporately they are bent on watering down their brand until there is nothing left.

Based on the information I have seen related to HBNR belts, the Delvac should be no issue.

That is great info. LSJ indicated the same. I am still burning around 1qt every 5k miles so I take that into consideration. I really expected oil consumption to stop with the Delvac.

Another thing I am trying to keep an eye on is DPF regeneration. If anyone has feedback on the POTENTIAL .2% sulfated ash difference between Euro and CK-4 MAXIMUM allowed limits I am curious how significant that is perceived. I can't discern any difference monitoring through OBD Fusion but...

I don't think that is an ignorant question at all. I am not an expert but the feedback I have received indicates that a CK-4 HDEO has a stronger add pack better suited for handling the soot load than the European spec alternatives (0w-20 dexosD included). Also, we know that soot and...

I agree. The soot in the oil with the 3.0 Duramax is unbelievable.

Thanks for sharing! Very nice and interesting to see 3.5k OCI's as well. I spoke with LSJ as well before switching to Mobil Delvac ESP 5w-40. At the time he didn't have any samples on this CK-4 oil but was convinced that the HDEO would provide better results than even 0w-40 Mobil 1 ESP. I am...

+1 on this statement.😉😁

If you get a chance it would be great to see your UOA. The more data available the better we can all make decisions!

I am still adding a ~1qt/5k miles. It was the same with Mobil 1 0w-20 ESP dexosD.

There definitely is...and it is an absolute fail in the 3.0 Duramax.😐

That is a good point. Also, after looking closer the sample probably isn't that far off from mine when you factor the mileage. Your truck is proof a 6.0 can be solid.💪🏼

I have been using Hot Shots Diesel Extreme in my 24v Cummins for that but will be using the Power Service Diesel Injector and DPF Flush for that going forward.
