What is it now?
Did a piston soak on the 18 Kia 2.4L this weekend
- Thread starter K20FA5
- Start date
I’m glad to report that the oil level is still at the full line and still very clean looking. Normally by now I’ve added at least a quart and it would be dark black.

i also believe the hot piston soak cured the oil burning in our accord
Just under 500 miles and just over a week of driving. I was adding a quart every week before, so this is a major improvement!
Checked it today and added oil to bring it back to the full mark. It took right at 1/4 of a quart. It’s been almost 2 weeks, and I was burning 1 quart a week. I can say for sure this did something! Now, how long before I have to do it again?? Either way, I'm pretty happy with the results!

i may have missed it, but you should really dump some HPL EC30 in it to keep cleaning the ring pack. you’ve opened them up enough now that oil should be able to get in there and with the EC30 if should clean them the rest of the way.
I did 3 different EC30 cleanings on it before this over the last year or so. I still have a quart left, I may try it next time.

i would because the rings may be opened up just enough to let the EC finish the job.
Seems like the piston soak did far better then the EC 30. Another piston soak would be better move I would think.
My Scion burned over a quart in 300 miles when I bought it. A piston soak improved that to about 1000. A second soak with two full bottles of B12 improved it to the point where I don’t add any oil between changes.
Try flush with BG EPR and add moa at the oil change. Had successfully stopped burning oil in a few cars ive seen
20w50 to mask it
I'd go for something more cost effective, yet effective.....
Rislone......mmo....gumout multi.
In my experience Rislone is not potent enough to open rings. Does good with ticking lifters.
That is quite the difference. Are these motors good candidates for mixing 2 stroke TCW3 oil in with the gas?
HPL EC is a low & slow approach
I wish they made a EC additive that could clean as good or better than their oils, but I understand concerns about clogging the filter
It made improvement in my oil burning 2AZ after a lengthy piston soak and idle flush
If you're gonna throw everything at it short of a teardown
- Start with the solvent piston soak
- Immediately chase with a strong idle flush (EPR/LiquiMoly)
- Then go to a cleaning oil or additive (high PAO oil or HPL EC)
The BG Dynamic oil service is also an option, but at $300+ it's kinda pricy
I'm eager to see my cut open filter when I'm done running it
The B12 soak completely stopped the oil burning on my sons 2005 Ford Escape with 200K miles. Soaked it over a 2 or 3 day period then did an oil change immediately, and another after about 10 miles.
I did it for about a year but after the oil bottle leaked I gave up on it. I couldn’t see that it made a difference.
