Schaeffer’s Supreme 9000............10,000 mile inervals...........wix premium filter...........46,000 on the clock now
The 5.7 HEMI in HD applications has not gone well, but yeah... In a half-ton, it is easily the best motor and tranny combo money can buy.This is part of why I'm so happy to have a Ram truck. The Engine and transmission.
This 5.7 Hemi has seen life and use in 3/4ton trucks for many many years!
Good tips on the oil life there. This thread has a lot of neat info in it
Update! I started doing 5k intervals, as I feel the MDS kick in much harder after the oil hits the 5k mark. Once i change it, MDS kicks in and out smooth as butter again. I've read the oil acts as hydraulic fluid for the MDS lifters, and it makes sense now.I do mine when the OLM is down around 10%. This is typically about 6,000 miles of daily driving/commuting to work. I use Valvoline full synthetic 5w-20. I also use whatever oil filter Valvoline Instant Oil Change uses on their Full Syn O.C. package.
This alone would convince me to do shorter OCI's, as well as rethink the oil I was using. If the oil had degraded to the point that it affects MDS operation at only 5k miles I'd be worried about what else might be affected by that oil. I have no experience with Valvoline full synthetic oil, but I use Redline 5W-30 synthetic, and when I was actually doing closer to 10k mile OCI's I didn't experience any change in MDS operation between oil changes. I disable MDS now, but I've also switched to 5k OCI's.Update! I started doing 5k intervals, as I feel the MDS kick in much harder after the oil hits the 5k mark.

If that's happening you need to stop getting that crap oil from an express shop. A real full syn oil will not be spent at 5k miles. You are getting shafted by them somehow or you are imaging mds being worse after 5k.Update! I started doing 5k intervals, as I feel the MDS kick in much harder after the oil hits the 5k mark.

And how many miles/months is that?i do what blackstone recommends based on the analysis
Gasoline Engines | Blackstone Laboratories
Use data to monitor your gas engine's health and decide whether you can run the oil longer, what oil to use, and more!www.blackstone-labs.com
This is a really good report! This oil was run ~2,300 miles longer than the last sample, yet ironAnd how many miles/months is that?
I check my oil weekly. It’s always full and it’s still clean when I change it. That’s just wrong. Valvoline full synthetic oil is good oil. I used to use conventional barrel oil on my older trucks at 3,000 OCI and would get 300,000 miles on all of them.If that's happening you need to stop getting that crap oil from an express shop.

Another thing is you might be burning oil and running very low if you are not checking it ever.
