Please post your analysis when you receive it, I am really interested to see the results because I have been using the same oil as you, Shell Rotella T6 since the first oil change, my truck has 65,000km or 40,000 miles, oil changes near 16,000km or 10,000 miles each time and when the truck calls for the oil change.
definitely gonna keep my eye on this, I’ve been wondering about switching to T6. Every machine I have at work I run that oil in. And thanks for the reply, I’ve seen the trend of higher aluminum, but it’s nice to hear it again from other EcoDiesel owners.
So, it doesn't look like Rotella did a bad job at all, but still a bit high on the aluminum front. But like we've heard and said, these engines have higher aluminum numbers than some. Thanks for posting these results djevox.
I'm also nearing my next change. Gonna send out another sample of Pennz 5W-40, then maybe a cycle or two with Shell T6. curious to see my metal numbers now at 40k miles!
Can you post the next sample results up here?
I absolutely will!
One common thing I am seeing from blackstone is they claim flux in the intercooler accounts for a lot of the aluminum and that takes a long time to clear out. I have no idea how long the time period that is though, and I haven’t called to find out.
Thanks for posting, the numbers look better with the Shell Rotella T6 than the other oils.
Did you actually add 6 quarts of oil between July and October of 2022?
Not too much of a climb, but maybe something to think about. Though I can’t imagine this motor falling apart at only 67,000 miles. I will say I agree with a shorter interval though, but that’s just my .02 cents. My last report held 21 PPM of aluminum. Gonna send another 5K sample of Pennzoil from my truck this week. Looking forward to seeing if my numbers jumped up more like yours did. Now at 40,000 miles.
I didn't even notice that on the report. I did NOT add any oil between any changes.
I think ill do 1 more @7500 miles as that will put my truck at 75k miles. After than one I think ill move to 5k intervals unless those results look better. Everyone seems to be similar with high aluminum so I'm not to concerned but I was hoping to see it go down. We had some very cold days and a lot more idling on this round of oil compared to others.
Thank you for getting your oil analysis and posting the results. This is what I think, I does not sound good if when they say listen for engine knock or to check for low oil pressure, it is probably a good thing that you change oil at 5,000 miles, I am not impressed with that Pennzoil. I would be worried if I were you, did you ever show the results to your dealer?
