Been keeping my eye on feedback for the Valvoline R&P also. Put it in my wifes ecoboost and my E46 with 259,000 miles last oil change. The E46 runs very well already but I may have noticed a slight improvement, could've been placebo though.
Not sure if it'll be worth using in my M340 since it's low mileage but I may still use it to ensure it stays clean.
Seems interesting from all the R&D they've detaild.

I think the BMW specs oil does a good job as well keeping the engine clean, at least in my car. So I am only using the Valvoline R&P from mostly curiosity (couple of 3000 miles oil changes cannot hurt), and because I got 3ea 5qrt for about $80. I am still at 500 miles, will change/cut open filter at 1000 miles.

Replaced the oil filter at 1,100 miles on the first Valvoline R&P fill. Did not see any sludge, but the oil seemed dark for 1,100 miles. My car even at 112k miles does not burn any noticeable oil. Always at max mark from oil change to oil change after 3-5k miles.

The real issue is the EGR function the ECU is programmed on the engine to reduce emissions, the carbon builds up above the oil control ring pack so I doubt an oil would have any effect on it.

Yes, direct injection injectors is cleaned primarily by fuel (detergent/additives), but not the intake valves. Valvoline says there may be a small cleaning effect by the oil vapors carried though the EGR system and then cycled back through the combustion chamber again and the intake valves...but they do not claim this oil to be designed for that. This is for the piston rings and other internal engine moving surfaces.

It helps reduce oil burn by freeing up the piston rings so they seal again, this restores compression...and stops/reduces blow-by.

Thank you very much for posting your attempt with the Valvoline restore and protect.

I have a '19 N63 x7. I use Amsoil and I change it every 5k.
I use Ceratec (now just one bottle) every like 3rd oil change.

I was thinking to use the Valvoline R&P and your experience sounds great.

What do you think about the noise that the engine is making while running the Valvoline R&P.

I have a 3.5 Toyota - old - and I put the Ceratec - it run soooo smooooth. When I changed to the Valvoline R&P - I changed the oil first at 500miles and it was really dark for a 500 miles - like you mentioned already. But now I am not too happy because the engine sounds just a little noisier.

I am very much looking forward to finish with the 4th oil exchange for the toyota so I can add back Ceratec. Then I will decide if I will put the Valvoline R&P in the X7 (has about 75k miles and I started the 5k oil exhange maybe at about 35k)

I do some Italian tunning in my cars almost all the time I drive them.

IS there anyone here that likes the Ceratec as much as I do? I put it in all my cars after I had the first shock when I put it in the N63 and it made it run sooooo smooth.

I have put Ceratec in my 2018 M5 and my wife’s 2021 Cayenne S and not noticed anything. But both cars ran fine before. In between the Ceratec, I use Moly.

Years ago the trick to cleaning an engine was to add a quart of automatic transmission fluid to the oil. The superior detergent additive in the transmission oil was the key.

But techs impressed upon me the best way to clean an engine is change the oil before it gets loaded with combustion byproducts (water and other stuff which combine to form acids). Oil is a detergent. In a pinch I've seen mechanics put a bit of fresh oil on their hands and use it as hand soap. Worked pretty good but of course it was not water soluble so the oil had to removed with a clean shop rag.

Treating an engine to regular and not too extended oil/filter services doesn't require some super duper oil just the factory oil will suffice.

Uhh, excuse me sir. That makes too much sense!

IMO, using the factory specs BMW oil at reasonable intervals with good quality filters is all you need. IMO, the Valvoline R&P is primarily for cars that have not been taken care of, or used with low-grade gas. I am using it because I wanted to see if there were any deposits that may needed to be cleaned off from the oil passages, timing chain/rail, piston rings, etc...and also some oil vapors may get recirculated back into via the emission system to clean the intake valves. Valvoline says that this oil was not made for intake valves, but may have a small residual cleaning effect in some cases. Some people reported that their oil dipstick (non-BMW cars) and oil fill cap got scrubbed clean after 500-1000 miles.

What I've seen online is that it did reduce oil consumption significantly for many people (piston rings sealed again). I never had an oil-use issue, so cannot confirm. I did not notice any smoother sound from the engine, still rattles like a diesel engine, especially when still cold. But that has been bothering me since 28k miles when I bought it, and it's normal for these early 4-cyl dual-turbo direct injection BMWs. The biggest sound reduction was when I replaced the factory timing chain tensioner with the later redesigned OEM version.

I did notice a smoother idle after a few hundred miles of highway driving with the Valvoline R&P. The RPM is not varying as much where I can feel it, and it seemed to have picked up a couple of HPs when accelerating from idle. Could be the potential better compression with the piston rings being scrubbed? I was reluctant to use the Valvoline R&P, because it is not BMW specs. But emailed Lake Speed Jr. (The Motor Oil Geek), and he said for this 2-3 oil changes it will not hurt.

Never used any oil additives. The only thing I ever use(d) are fuel additives, like Marvel Mystery Oil in the fuel, and Techron Complete for the injectors and combustion chamber. I am not against using MOS2 or Ceratec in the oil, but based on what I gathered about additives in general is that they are unnecessary if using BMW specs oil and Tier 1 gas. I am also concerned as some oil additives truly work miracles, while others test acidy, etc in the same engine. A particular oil when mixed with an additive can change its chemical qualities. The automotive oil is a careful/exact chemical mix of base oil and detergents, etc for a particular engine. And since that oil was not designed to work with that additive you add, it may change the entire oil in the engine to become more acidy, or less resilient to viscosity breakdown, etc. It's a hit and miss as far as helping or hurting or doing nothing.

If one could be sure that Ceratec does not change the oil chemistry in their car, I would consider using it for the sound reduction effect.
