Valvoline Restore and Protect: 2017 Santa Fe 2.0 T Sport Ultimate

[Bonz]

Daughters vehicle in the title started using oil at a 1qt/thousand miles in the last year. That engine is not under recall from Hyundai however it's a known issue with the oil control rings on many of the cars from that era. 70,000 on the engine when it started to use copious amounts of oil.

She's getting her master's 1200 miles from home so I don't have a chance to do things on her car regularly. Had the chance to fly and see her and drive her car back east to see my folks in the last week.

Did a change with Valvoline R&P 5W-30 before I left with just over 74,000 miles on the odometer, used a quart in the 700 miles getting to where I was going. GDI cleaning with CRC turbo and intake valve cleaner, a bottle of Techron at every fill up (ran the tank down before each fill up) after the initial 700 miles. Topped it off with a quart after the first 700 mile run. Then did a 250 mile run to Philadelphia and back. Still used a third of a quart. Topped it off, left Pennsylvania and ended up back in Chicago today, almost 700 additional miles and no noticeable consumption.

With the oil issue appearing in the last year, it hadn't been driven a whole lot and I think that led to less carbon build up on the rings and thus a relatively quick fix with the R&P in about 1700 miles total.

My 2010 Acura TL SH AWD (known issue with that engine and build up on the rings) with 215,000 miles on the odometer is on its third change with R&P. I'm just now starting to notice an improvement but not to where hope it will end up.

Anyway, I'm resting easy that she doesn't need to be adding oil, at least this point, moving forward.

Don’t give up on the Acura. On my oil burner things really started happening from the 3rd oci on with R&P.

 

[SwampSurvivor]

I've been pretty impressed with R&P In my truck.

I'm going to be putting some miles on it soon towing my jeep around, I'm curious to see how it does at that point. I expect it to go a bit more on the consumption because the hotter oil will leak quicker out of the head.

Here is my Blackstone lab results with Restore and Protect. 1% gas is due to direct injection and winter weather, nothing i'm to concerned about it, prior oil analysis during warmer weather was less than .05%. I could easily go 10,000 oci but i'm not going to push much more than that. I probably stick in the 8,000 range to keep my TBN above 2.0 and keep my fuel dilution lower, not uncommom to have blowby on direct injection. Notice my Silicone is more elevated then I had on previous vehicles, air box design is horrible on rogue sport and i'm moving away from Fram Ultra air filters and will try a Purolator 1, my filter was pretty bad looking after 30,000 miles and it killed my gas mileage so Frams 4yr 40,000 miles doesn't work for me.

These 2 products worked better than a dozen other products I tried over the years.

BG EPR - - - 2 treatments 100kms apart cured many oil drinking german cars we have owned.
Hotshots stiction remover - - 1 treatment at 4 oz per quart then 1 more treatment at 2 oz per quart - used in a few Korean oil drinking engines.
Both eliminated 98% of the consumption.

Personally I preferred the HS - - -

My sons 2019 Santa Fe with the 2.4L Theta II engine hasn't responded at all to the R&P. He's on the 4th OCI. I think it's just the Hyundai low tension rings. Not much can really be done. Maybe a piston soak will help. He's not burning that much oil. Maybe 3/4 of a quart in a 4K OCI. That's pretty good in these engines.

or simply not great engine design?

You would think by 4, you would get something.
Does he do any highway driving - - if not go for a 1 hour drive and drop 1 gear.
Cruse in 5th or 7th depending on the trans

 

[Chief2025]

Who knows......
Honda, Toyota, Audi , ect all have piston ring consumption issues.....somewhere in their lineup.

 

[Urshurak776]

Yes. Thought that was implied.

He does do highway driving. I can have him try that.

He also does uber eats. I think that (lots of idling) is part of it.

 

[Chief2025]

Yes. Thought that was implied.

Personally I think every manufacturer needs to lower their OCI's.
Especially if the engines use DI - - so much more soot and carbon end up in the oil from blow by.
10k+ is too much for most city driven vehicles.
Low tension rings can old take so much.

You could just cut to the chase on that Acura if the RP has not done much yet : https://www.driveaccord.net/threads/i-solved-oil-burning-in-my-accord-4-cylinder.539415/

Pistons are likely scored.

3/4 of a quart in 4000 Mi is perfect, time to change the oil at that point basically.

On the Acura I mentioned, Saturday afternoon I did a CRC GDI intake valve and turbo cleaner in that engine despite being naturally aspirated and port injected.

RPM went up and down as I squirted it in, let it idle for a minute never smoked a puff before I shut it down to soak. After an hour or a bit more started up clean as a whistle, backed out of the driveway and as it started to roll down the slight grade of our street, I shifted down to first to get the Pistons up against compression and I have never seen such a white cloud of smoke that went on for two or three hundred yards before going away. Made some interesting noises as I very lightly accelerated and rolled out a few times. After that short time of smoke, took a little bit to relearn the fuel injection parameters parameters since I had squirted it in behind the maf and the intake was open.

I chose a CRC GDI cleaner because it is high PEA which attacks carbon. And man did it clean out carbon. As well my reasoning said it might help with the known issue of carbon in the Rings which leads to the oil consumption in the first place. Continuing with Valvoline restore and protect, I'll update you guys after the first thousand miles on any change.

Just keep using VRP as the Hyundai's main oil. It's a Hyundai, one of the top problematic cars with ring jamming, most respond within 4 oil changes, but your son's could be an outlier. It not like $29 for 5 qts is a deal breaker. Doing some "compression braking" with manual down shifting the auto trans with a max rpm being 4,000 rpm. Going down a semi step hill is nice, so you can keep a load on longer then a few seconds that flat compression braking gives you. This helps load the top side of the ring lands. That may help really bad jammed rings loosen up and drop their jammed carbon. Also do some heavy foot driving to load the rings. Red lining it is not needed or wanted just get up to 4,500-5,000 max.
