Will HPL PCMO help my oil consumption?

[MrBaumTastic]

Does anyone running HPL PCMO experience oil consumption at all?

I'm asking for any weight/grade oil, any vehicle, driving conditions, mileage etc.

Also, what about Royal Purple or Amsoil guys?

HPL

What are you fishing for? I have read some threads that said there was some make up oil over 10-20k oci's. Are you having an issue?

Just wondering if oil consumption in my vehicle could be resolved or at least reduced by switching to HPL.

I tried Amsoil SS in my 2017 Hyundai Sonata with 80,000 or so miles at the time, and though it performed a lot better than the Quaker State full synthetic I was using, it was still consuming a quart every 1,000 miles and at the price point per quart of Amsoil SS, I simply could not keep that up.

My understanding is that HPL is at a similar price point as the Amsoil SS, so if it performed similar to the Amsoil I would probably not stick with it. But... If it did work a lot better...

Currently I'm driving a 2019 Kia Sportage the same engine as my 2017 Sonata, I guess I have a thing for these engines lol but anyway, I'm using Valvoline restore and protect (5W30) and I have over 6,000 miles driven over 2 oil changes in the past 2 months. I'm more than halfway through my third (planned 5k OCIs) and consumption doesn't seem to be improving very much. I think I might be loosing a quart every 600 to 700 miles, but it's still well within the same ballpark that I'm trying to get out of. Perhaps it's just wishful thinking but I would like to be at at least one Court per oil change interval, so if I'm doing 5,000 miles OCIs I'd like to be at a court every 2500 miles. At the rate I'm going that will be never lol

And before anyone asks the car has had the following performed:
- New spark plugs (NGK Rutheniums) put in at 100k
- PCV valve replaced at 105k

In my driving habits consists of an 80 mile round trip daily commute, and pizza/Uber eats delivery driving (by my wife). We put a lot of miles on but we don't experience stop and go traffic, and I never idle excessively or short trip. Also we only use high octane (90 or higher to eliminate ping) TopTier Fuel from either Valero, Sunoco, or Citgo, that's just what's available around us.

Yes HPL will clean the rings. I would start with a B12 Chemtool piston soak. Then either run HPL or Valvoline Restore and Protect. Valvoline will clean just as good and if it is burning in the beginning, it will be cheaper to top off. After the consumption slows I'd then switch to HPL if you want to do longer mile changes >10k oci's and let the HPL keep cleaning.

I saw about 1oz per 4k miles accumulation in my catch can on HPL PCMO. No consumption.

That's my plan, just taking longer to get there than I had hoped. I knew it would take a few OCIs with the Valvoline Restore and Protect (some thousands of miles of driving, so a while) but at the rate my oil consumption is improving, I could just as easily try something else.

I am also planning on doing a piston soak, at least two over the next two oil changes, 8-12 hrs soak time at least.

Your oil consumption may have nothing to do with the oil or ring deposits. Some engines just consume oil. Two of my previous cars consumed 1/2qt per 3k miles since new. Both ran like new well over 150k.

You're right, but a qt every 500 miles? That's a quart a week for me on my commute to work alone.

It is either a carbonize oil control ring or excessive cylinder bore wear. HPL may free the oil control ring but many forum members have taken aggressive piston soak methodologies with mixed results. No guarantee it will improve oil consumption. However there are a limited number of cases who have been successful.

That is excessive. Did the engine consume oil from the time it was new?

I'm counting on the number of cases who have been successful to justify trying it, whether it works or not. As you said, it may not be stuck rings but good ol' wear and tear.

If you do the piston soak first it should make the largest difference. Then the oils can keep cleaning up the job. HPL will take time just like R&P so you may find the difference is moot.
Here is what came out if my Honda in less than 4k miles with the Valvoline so dont think it can't make a difference in shorter miles.

Sorry I should have clarified, I haven't owned either car since New. I got the '17 Sonata in 2019 with 25k miles on it and it started consuming oil around 60k miles I don't remember exactly. That was totaled in an accident in March.

Enter the '19 Kia Sportage, it had 98k miles and has been consuming oil since I drove it off the lot

The color of the oil has zero relevance to any cleaning potential or action that it is performing. We’ve been told by oil formulators that aminic antioxidants are largely responsible for the color change in oil, and they darken due to heat, not any cleaning effect.

Yeah this was red and chocolate colored not black. It also has been removing varnish and baked on goodness. So in this respect it does. So I appreciate the tip, it is not necessary

Hopefully your catalytic converter survives the traumatizing ordeal. Already a high mileage 100k engine, consuming oil at rate of 1qt/1k mi and then several future piston ring solvent soaks which blows Vatican City levels of a newly elected Pope white smoke. Best of luck.

I would plan the piston soak at the same time as the oil change, especially depending how much B12 you use. My concern would be all the B12 leaking past the pistons and diluting the oil too much. The Kia/Hyundai motors have a reputation for a reason that may or may not be oil related depending what you read. Solvents that reduce lubrication while running in them make me uncomfortable some.

That doesn't mean I haven't done them like BG EPR, Gunk, Motor Medic, Liqui Moly or other very liquid versions of add, run 20 minutes, drain, change. The BG Dynamic seemed like an interesting product also.

Fortunately I haven't had to do any piston soaks yet. Just some of the reading I would personally want to do all the first turns by hand to clear the cylinder with plugs out and then add a small amount of oil to lubricate the sides and add some sealing for compression. Something maybe like a fogging oil spray.

This is what happened the first OCI running HPL in an Elantra we once owned.

Thread 'HPL cleaning 2013 Hyundai Elantra - cut filter element'

Apr 30, 2022

This is the Fram Ultra filter element from our 2013 Hyundai Elantra with 115,000 miles on the clock. The oil is HLP 5w-20 HDEO that was in service for 10,000 miles the filter was also in service for the entire 10,000 miles.

These pictures reinforce the need for a filter change or two during a 10,000 mile run when following oils that don't have the ability to clean. I can't explain the relative lack of metal compared to the previous filter cut at 105,000 miles, not what I expected. The cleaning ability of HPL oils still amazes me.

These pictures also reinforce that if you aren't cutting...

That was my first thought, checked and it wasn't.
