Valvoline Restore and Protect drawbacks?

[robburrow5150]

One downside might be - I'm not sure if it's suitable for turbo engines. I don't think it is.

What makes you say this?

The so-called Turbos in today's Engines are Liquid Cooled? What is the weight of the oil these engines are specking? It is either 5W-30 or a lower grade.

Well to nitpick this just a bit, Valvoline expressly states it dissolves the carbon and suspends it in the oil. Not merely “dislodges” chunks.

I had this discussion with @tired before, but let me ask again:
Does it mean dissolved in the oil (whatever material is) won't be caught by the filter when the oil goes through it? And if not - why?

He's wrong. There's no basis for that statement. I would recommend not engaging further.

@melk this reply answers this question. I don't think this topic needs to be further flogged. I've already been round and round about it with him to be right back where we started. I wouldn't waste any further time.

Mostly because of its viscosity and HTHS values which are on the lower end for 5W-30 viscosity. However, a few people on here use it successfully in turbo cars, including German ones that are known to always run hotter.

That could be right. Todays turbos might operate at much lower RPM and temp. than turbos a couple decades ago or especially those in race cars.
I haven't researched that, but is highly possible.

Just saw at the auto show last week that the Nissan Z turbo gauge goes only to 25,000 RPM which is very low for a turbine speed, but after all that car is bi-turbo. So in that regard 25K might be good enough and also we don't know the size of the turbos either. It's V6 bi-turbo.

So chemistry dictates that the carbon itself is not being dissolved, it is being dislodge by having its adhesion degraded. It's fundamentally a mechanical removal even if by chemical means.

Could it be the gunk is dissolved to carbon and the carbon is then dislodged.

We agree that there are no Nuttella-like floaters roaming around. The blasted thing is reduced to something manageable.

A few members here reported substantial cleaning on engines that have be run on quality oil.
You would think a PAO/AN/POE true synth would keep an engine free from varnish and gunk - specifically the piston ring lands which would be my primary area of concern - along with the toasty exhaust runner roof(s) in the head

If the engine is short tripped - cold driven - and low rpm -longer oil change intervals - even good syns can keep up .
Valvoline Restore and Protect - comes along and provides an interesting solution.

I wish it was around when we had our odyssey with the Uber junk rings / piston deactivation - - - - would have been a game changer.

The filter I removed after 1K begs to disagree.

wow - - -what was the mileage BEFORE you used valvoline?

Around 125K. These engines are notorious for burning oil. I've owned three and have piston soaked them all, and when I cranked the engine to blow out the solvent a whole lot of carbon got blown out with it. This is the towel I laid over the valve cover when I purged the cylinders...and this wasn't the worst one.

still not going in the industrial 413
20W50 is what it gets

As in Mopar RB-block 413?

 

[Hohn]

I wish they could use a better base oil. It seems to be a basic group 3. Nothing wrong with that, per se, but it’s not an extended drain oil.

I’d love to see a PAO or at least GTL version.

Who knows, maybe the secret sauce is incompatible with more refined base oils?

I suppose, but it's really tough to fault Valvoline Restore and Protect by the two all important measures of cleanliness and wear protection. It's proven to be superb at both. So maybe it goes longer a bit if it starts out as a higher TBN oil or has a bit better bases. But I think Valvoline nailed it with this oil overall balance of performance and cost.

Our UOA section is full of oils that cost as much or more and had worse wear numbers.

Oil quality changes over time. Today's oils are several steps above the German Castrol that used to be the bee's knees here at one time. It is expected that a new 'hype' will appear.

Yeah. Castrol has been going thru some strange times as of late. At one time Castrol / Mobil and The Yellow bottles crowded out my local WalMart shelves. The only one that came close to the shelf space as those is Valvoline. Castrol got in a habit of coming out with a "new" product / formula as often as we change socks. Then in the last couple years ..... the Castrol company changed hands (Valvoline did too) and the Castrol products began to disappear. These days most stores around my area have only a very few Castrol offerings. Their EDGE product is supposed to be on par with the big boys, Mobil 1 / Pennzoil and Valvoline but they appear to have scaled back their advertising and even store product offerings? No idea what that means? Maybe they put a new bean counter in charge as CEO to dive them into bankruptcy soon....? Like many late great companies have done to themselves.

Castrol EDGE Euro 0W-30 is still quite good.

BP is trying to unload Castrol at the moment. Might explain some of it.

There is so much research out there showing 5w30 with lower viscosity protecting turbo engines very well. Changing the oil is more important. As long as your doing an OCI of 5,000 or less, any 5w30 will protect a turbo.

Yes, it's an excellent oil that does what it claims to do. It's not an extended drain oil, but it's not advertised as one.

Aye, but this is why we don't bench race used oil analysis. Different chemistries will have different "signatures" and you can't directly correlate that to actual wear in service. What we do know is that despite its cleaning ability, this doesn't seem to present as increasing anything we might expect to see increase in typical used oil analysis. There have been some exceptions, but by and large, we see average or below average numbers, which points to a well formulated product that does what it's advertised to do without any negative side effects.

They did in fact - to some private equity firm.

No kidding. Less than two months ago. I knew they wanted to sell for a while.

My first thread here was about my trusty econobox fed exclusively on Royal Purple from new, at 3k to 6k OCI. At 125k the dipstick looked like a Pocky chocolate covered biscuit stick. Even the top was the same kind of yellow.
Quality oil...

So what was / is the outcome of a dipstick looking like that? It certainly does not sound very good.
Did you have coolant in the oil? Blown head gasket? What type of engine is that? Just curious.

I guess I described it wrong. I was describing the color. The deposit was otherwise dry color only. No gunk. And it (the stick) was cleaned by Valvoline Restore and Protect to new shine in 500 miles.

Engine was a perfectly running 3.3 gdi Hyundai which ran like a champ and gulped through 1qt of oil every 1000 miles with Swiss watch precision.

Since replaced under extended warranty because of the oil consumption.

 

[buster]

Simple: It's an RC API SQ oil. It doesn't meet more stringent approvals and hasn't been tested for extended drain capability. It punches above its weight but you can't make it into something it's not.
