Well, I mean, it's a diesel with EGR so it's black by 1,000 miles normally and it looks the same with HPL.

The wear metals you posted are similar to what I've seen in my EcoD after a 10,000 mile run. I would change the oil and filter immediately, if not sooner.

I'm using it in my truck. I have 2qts in the sump with VPBE 5W-40. I have about 1,000 miles so far. I changed the oil filter today. There was nothing different or abnormal that I could tell from cutting the filter and inspecting it with my eyes and a flashlight. I plan to run this cleaner for...

The question has been raised by @BoiseRob if this is for HDEO applications. Something about Adpack? So-is it for HDEO applications?

Well thank you. I hope this stuff will do something. https://www.advlubrication.com/collections/automotive-lubricants/products/engine-cleaner

I was told that the oil I was using, DELO 400 XSP 5W-40, starts out thick. But yes you'd think 6% fuel dilution would lower viscosity more. I'm no expert though.

Moderator- The oil in the UOA is NOT Delvac 1 ESP as it is written on the sheet from OAI. I have since figured out how to change the information on the eoilreports dashboard. The oil is Chevron DELO 400 XSP 5W40. The oil was in service for 5 months and 5,500 miles. About 2,500 of those miles...

It has 112,000 miles on it currently. Interesting idea about the seal of the HPFP. The HPFP is under recall with no parts available until next year supposedly.

I've got a little fuel dilution problem. I've discussed this with @OhioTech and he suggested I use some HPL Engine cleaner or just change from the oil I've been using to HPL's HDEO. I've ordered the cleaner and plan to use that for the recommended duration then use the HPL CK-4 HDEO 5W-40. I've...

I asked Mobil about the 0W40 a while back and the reply was that it was only available at GM dealerships. Quote: Mobil 1 ESP 0W-40 will be offered in the US only to GM dealers. I don’t know the reason behind this, but that’s the information I have. Regards, Steve W. Scott Americas...

The virgin sample I linked above shows 9 abs/cm. What exactly is the value this lab says is 133%?

I recently purchased two 3 gallon cases of Valvoline Premium Blue Extreme 5W40. I'll be using that for the next change.

I resampled after a full 10,000 miles.

Yes, please keep us posted. I'm running Delvac 1 ESP 5W40. Devac 1 ESP 8,000 mile UOA

Thanks. Tired Trucker. I guess it's all good Quote: There is only one Mobil Delvac 1 ESP 5W-40. Packaging does sometimes go through changes and color can be slightly affected by a variety of factors from batch to batch. I do not see anything alarming here and you should rest assured that...

Originally Posted By: pb379 Are there any differences between these two? Has the formulation changed or is it simply new packaging? The one on the left is an older single gallon I got from NAPA and the one on the right is from a box of four I got from a different NAPA that came from the...
