Can't believe I haven't seen this thread in the past ...
My truck 2014 Ram 1500 QC 4X4 5.7L Hemi , 6speed xsmn , .355 diffs.
I tow pretty regular typically under 3k lbs sometimes weekly ( boat & fishing gear ) I've towed medium wts 6-8k lbs several times as well ..so all my UOA's have some towing .
Here's my latest Blackstone Labs UOA .
This one is Redline oil , a 50/50 mix of 10W-30 & 5W-30 .
The first one On the far right ( 8k) was Redline 5W-30
The second one (6k) was a 50/50 mix of Redline 0W-40 & 5W-30
The third and 4th one was the same oil , I just took a short uoa I was tracking the iron levels . This was Redline 5W-30.
The 5th one (2100 miles) was a 50/50 mix of PUP 5W-30 & 0W-40 PUP. I changed it only because I had developed a very faint tick tick tick sound at idle ...cold and hot so I opted to dump it early and go back to Redline oil ....
The final UOA , as stated above is a 50/50 mix of Redline 10W-30 & Redline 5W-30 oil .
The iron and copper is continuing to drop in my 5.7L Hemi on Redline and my engine is incredibly smooth and quiet .
The filter for all the Redline oils have been the RP 10-48 , I used the WixXP filter for the short PUP run .
This time I changed my oil to a full 7 qts of Redline 10W-30 coupled with the larger RP 20-820 Filter . So far about a thousand miles and all is well and EXTREMELY smooth and quiet .
I started using Redline oil at just under 20k total miles , after the "free" dealerships oil changes . My 5.7L was very loud on the junk dealer oil and at a drive through I'd have to speak loudly and repeat my order !
It took about 750 - 1,000 miles for Redline to quiet the engine ....wish I had never done the free dealer oci's ...
