High Mileage vs. VRP

Based on the discussions here it would seem that the cleaning potential of VRP isn't just a marketing ploy. However, I cannot find any discussion about a comparison to high mileage oils and the seal conditioners that they typically contain. While most high mileage engines (100k+) could probably benefit from a slow, extended cleaning that VRP seems to provide, is it worth denying them the high mileage additive package for 4+ OCIs?

I have three cars over 100k miles (107k, 131k, and 162k miles), and while I would be willing to pay the extra few bucks for VRP to clean them out, I have also been running high mileage oils in them since 75k miles each and have not experienced any oil leaks or issues of that sort.

I am just curious if anyone has more information or more educated thoughts than my own.
 
VRP will still have seal conditioners, just at a lower rate than HM oils typically do. If you've already been running HM oils, I doubt you'll see any issues with a switch to VRP. JMO.

Wouldn't hurt to try it in the 162k ride and see what, if anything, happens.

The 162k ride is (was) a severely bad oil burning Camry that just got done a piston soak with Berryman's B12 that seems to have fixed her up pretty darn well. VRP wouldn't have made a dent (HPL EC and BG EPR tried and failed as well) but could be of some use now.

I was actually thinking of using the VRP on the other two, since I just averaged out the OCIs for each. The 131k is a 2012 Civic that has averaged 6806 mile OCIs over her lifetime, and the 107k is a 2018 Pilot that has averaged 5939 mile OCIs over her lifetime. Both run just fine, but I don't put a ton of miles on either at this point (and very few highway on the Civic) so at least with the Civic I thought that maybe she could benefit from a slow cleaning since I will never get rid of her as my "around town" car. That 9th generation has been the most reliable car I have ever encountered.
 
I would never use High Mileage as the very chemicals there are more of in HM accelerate elastomer deterioriation. Just use R&P. Orings might need to be switched to Viton.
 
Unless the car in question is leaking oil from places like the crankshaft or cam seals, HM oils are of no benefit. Valve cover and other gaskets aren't helped by HM seal swelling additives.
 
I have one vehicle over 300k miles. One over 200k miles and two over 100k miles and none are using HM oil with the exception of the Dodge Van only because at oil change time HM was on sale. Zero oil usage in 5k OCI's.

Other than higher seal condition content, what else is there to a HM oil vs non-HM?

Seems to me the basic rule is "if it's not leaking, you don't need HM". Or is that incorrect?

You can follow that if you wish. But at the same time it’s not going to harm things or destroy seals if you do.

As you’re implying especially these days with HM oils mostly having an API SP license there cannot be much of a difference, and no one has quantified what that is.

Depends on the brand. Sometimes there are other differences. The HM I am currently running, Valvoline EP HM, is blended slightly thicker and uses a GTL base oil instead of Grp III like the standard EP offering. Add pack also appears to be slightly stouter, but they are close enough it could just be standard deviation from different UOA's.

Another brand may have no difference at all aside from seal conditioners.

My thoughts have been that like most things with vehicles it is easier to prevent than to fix. Is running high mileage oil from 75k-on for three cars responsible for preventing oil leaks in all three? Maybe? Maybe not? None of them are leaking anywhere, though, so until they do I can't say that it has been a fruitless endeavor.

I run 5 qts. Valvoline extended protection high mileage 5w30 and 2 qts of restore and protect 5w30.......... best of both worlds and runs quiet and smooth

Claims are it takes 4 OCI’s for VRP to complete a cleanup …
How many do you figure in both worlds ?
 
Not sure ......I had 2 qts left over so to avoid buying 2 5qt jugs ..... I threw that in with 5 qts ep/hm..... next oci all ep/hm 5w30

Maybe VRP needs 4 OCI's to replenish additives to clean gunk?
