VRP: what tests/evidence would convince you one way or another?

[Jetronic]

I wouldn’t necessarily disagree, was just curious what the most skeptical would consider definitive proof.

the most sceptical wouldn't accept anything they didn't witness themselves.

I don’t need a test other than my own. 6k miles on my first use in my 2009 Mazda 5 and oil consumption is down about 50%. Mind you it only used a quart in about 6k miles before that. But still… down to half a quart now. I would call that good success already and its only the first OCI.

The Mazda 5 has 193k miles at the moment.

Nope. Not good enough. Only marketing. Clearly you’re a paid spokesman. Or an AI bot. Or just a figment of our collective imaginations due to hallucinogens planted in the public water supply by agents of VL Inc.

I think YouTuber DIYAutoworksNG makes some interesting observations that sticks out in my mind. One of them, better piston ring sealing and less blow-by @ minute 2:36...

 

[SubieRubyRoo]

Right. This first OCI will only be approx 2k miles so if the color darkens considerably, that certainly could support some anecdotal evidence to follow up on.

Color doesn’t give any indication of cleaning. David from HPL told us in another thread that it is mainly aminic antioxidants that change color from heat they are exposed to.

Dipstick stain removal?

I’d like to see one of those control test instead of V8 truck going 500k miles a small turbo 1.2, 1.3, 1.5 which is the tread and let’s see the tear down

 

[hemioiler]

From my perspective, I'm sure that it cleans very well. However I'm sure that as a complete package, it fails to meet or exceed the offerings from HPL (which happen to clean very well in addition to being an exceptionally good oil all around) and I just prefer to run that instead.

Hopefully someone here is willing to use their lawn mower for a test, involving taking the piston out and photographing it. Do it before using VRP, run VRP for a long enough time (~ 120 hours) roughly corresponding to a typical OCI in a car, then photographing the piston. That requires serious dedication, so I doubt any of us will do it.

No other tests needed. Valvoline has already provided enough proof.

More than just their tests would prove necessary.

 

[buster]

Well Valvoline did the work for you by testing it in their engine lab. They also did field testing with it. Anecdotal and photo evidence is showing it works as advertised. The only people that may complain about it are those thinking you can run it for 1k miles and expect everything to be 100% back to OE cleanliness levels.

Would anyone know how effective is Valvoline Restore and Protect on Varnish below the valve cover?
I have a bad case of this varnish identified when the valve cover gasket was replaced.
I have 6 quarts of HPL EC30 in my stash, was thinking about using in 1:5 ratio for each of the next 6 oil changes (OCI = 5,000 miles).

But would Valvoline R&P be more effective against varnish. Probably the answer is it's unknown, but just wanted to check if anyone has had any good varnish removal experiences with Valvoline R&P.

I did the first oil change to me yesterday after I purchased a 2014 Acura TSX (K24 engine) with 25k miles. Since the prior OCIs were around 7k-ish miles but 2-3 years on average I wanted to start fresh and since VRP is the talk of the forum and affordable I decided to run that along with a bottle of HPL EC30 I had lying around.

I do not have the depth of knowledge as some of you so I’m curious how I - or any of you - could be convinced in your own car that 4 OCIs worth did “work”. Since HPL EC30 is part of my initial mix and since I asked Dave on its usage in another car I used it in, I will be doing a quite short initial drain/refill 2000p-ish miles from now per his recommendation and changing the filter; will be cutting open the old filter for inspection. What else, short of doing a full tear down, would be a good test/evidence for its purported effectiveness after 4 normal OCIs?

You probably don't need VRP and HPL EC30 together, on the first use.
I would say use VPR for at least one oil oci then do VRP and EC30.
If it's a sludgy I wouldn't even use VRP at first do one or 2 short oci with something cheap and known to stay clean like PP, then VRP. Removing the sludge from an engine isn't something you want to rush.

I have an older Snapper lawn mower the burns an insane amount of oil for every tank of gas. I will try some R&P......

 

[D1dad]

is this a short change oil or can I run it for normal intervals? Assuming the engine doesn’t dilute it.

I’m speculating, but I think anywhere the oil comes in contact with should work to remove deposits. I personally have seen much more evidence on this board and elsewhere that show vrp can remove varnish as compared to ec30

Made to run full oem OCIs. Valvoline also claims it won’t overpower the filter so no early changes needed
