High Performance Lubricants Engine Cleaner

No. I would not mix the two.

I am just now learning some basic chemistry in relation to esters, solvents, and such. Is there some specific concern about combining the two, or more of a general sense of “no real benefit, potential harm” ?

Best to reach out to HPL. Too many people around here are just guessing.

We don't know the exact chemistry behind Valvoline's R&P. They're very tight-lipped about it. (understandably so) I would be concerned about cleaning too much too quickly if the engine has a lot of sludge. HPL's oils clean more aggressively than the EC. The EC is meant to be used in transition to HPL's regular oils, providing a slower cleaning action to eliminate looser deposits before the more aggressive oils are used.

I can’t talk to specific chemistry’s. There have been many articles/warnings about additive clash. So I try to keep things simple and not mix.

I agree, it’s probably better not to mix them for now since VRP chemistry is a mystery (even though EC can seemingly be run with any other oil under the sun?) but because nearly all my cars have 6qt sumps it’s just so tempting to toss in a 5 qt jug of VRP + 1 qt EC

It’s kind of funny to me how we can be cavalier about doing extended drain intervals using off the shelf oils, which we know increase chances of deposits, and yet be timid about cleaning.
