Well, that may be true but this site has been referencing these same UOA's for decades and this is the first I have seen their valdity challenged with this level of disdain. Also, I am unclear on what would satisfy conclusive DATA in your scenario. I personally think it would be highly...

Nailed it. Ever heard the phrase "paralysis by analysis"?? Is it it possible that the conclusion Lake is presenting is not "scientifically" correct? That is likely based on what several are mentioning here but it is also extremely likely that these engines will 100% of the time show decreased...

I am really curious now. I have been reading this forum off and on for close to 20 years and have great respect for the contributors including yourself. What would really be exciting is if experts on this forum collaborated with Lake in the sharing of ideas. I get (or assume) that several...

That is odd, Lake uses his real professional identity and provides reasoned data to the universe. Even the most respected contributors on this forum are hidden behind their user names.🤔🤷🏻‍♂️

These 3.0 Duramax engines run ~230-240°F at operating temps.

I bought a case of gallons on Amazon when it first released. Should be good for a couple years a t the rate I am using it.😉😁

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...
