Update
Oil level is still on full today! I added 1/4 quart late last week, but it’s been quite a while now and it’s still not using. I’m very happy!
Awesome, this inspires me to try it on a friend's car that I know is burning some oil (2013 KIA Rio).
I would. And I will, when I replace spark plugs. Also was thinking of Amsoil Power Foam, that way the upper cylinder area can get some cleaning too.
I put some thought about this topic during lunch. I know there are many approaches to a problem and solution.
While my car doesn't currently burn any significant oil currently I'll keep this topic in mind for future references & friends that have oil burning issues.
Let me know if my step method of approach is sound? Its probably excessive for most here.
1. Car front wheels on ramps
2. Remove spark plugs
3. Turn crank until pistons are even depth
4. Fill each cylinder with around 4-6 oz of B12 or Top Engine Cleaner & cover spark plug holes
5. Wait 6 hours
6. Check for leak down
7. Turn engine crank
8. Top off with more B12 / Top Engine Cleaner, turn crank & cover spark plug holes
9. Wait another 6 hours or overnight.
10. Check for leak down & turn crank
11. Repeat step 8, 9 & 10 if desired
12. Check for leak down, drain/suck out remaining solvent in cylinders
13. Wait 6 hours or more until pistons are dry
14. Add small amounts of engine oil (1-2 oz) in spark plug holes & turn crank to lube cylinder walls
15. Suck out any remaining excess oil in cylinders
16. Install spark plugs and coils
17. Drain contaminated oil & filter
18. Fill new oil to crank case, new filter
19. (optional) Add fuel system cleaner (BG 44k / Techron) to gas tank (to accelerate oil wash off on pistons on car startup)
20. Drive for 500-1000 miles or until fuel with cleaner is exhausted
21. Drain oil or use engine flush (BG EPR) & Drain oil / filter
22. Fill new oil & filter.
23. Monitor oil consumption per x miles driven.
