Valvoline Restore & Protect

i have seen the EP HM load up a filter on a few trucks. i think it runs pretty clean and is my favorite of their oils.

Does regular EP have a similar effect or is it the ester of the HM that does?

It was speculated a while back that M1 HM EP used a good amount of AN. I have no idea if that's true. I'm not sure if the EP HM can clean more than the EP.

I'm of the opinion that they can clean, but limited to sludge and easier to remove deposits. I trust the Valvoline guy that worked for Infineum for 16 years when he said piston deposits are another animal and almost impossible to remove.

haven’t ever used the EP, always paid the extra for the EP HM (it won’t hurt anything) to clarify, talking about valvoline ep hm. i am not a fan of mobil products other than M1 0w-40 and delvac extreme.

Well in truth, it was mostly group III PP and I went a bit too long on ODI sometimes by following the OLM to 0%. I figured the OLM was calibrated to petro and I could get away with it using at least a group III. I think that was true in terms of wear, but not cleanliness. And as I've posted, I've come to believe that cleanliness is actually the more important thing in a modern engine.

VRP is the right oil at the right time for the needs of many of today's engines. IMO.

My theory is that even name brand group III synthetics run for a 5K OCI is too long leading to deposits - especially oil ring deposits . My Hyundai / Kia always receive 3.5K to 4K mile / 6 month OCI’s with M1 which is being continued with VRP . *Even if I had another brand of vehicle with a similar 5 qrt. sump , I would continue with 4K mile max / 6 month OCI . Lastly , if I decided to use another oil again (after running VRP for at least 6 OCI’s) it would be with M1 0W30 ESP. However , when VRP cleans as well as it does and offers great wear control as it does - why even consider changing back to another oil ?
