IM DOING A MAJOR SERVICE(FOR A FRIEND) ON A 2003 HYUNDAI ELANTRA WITH 1.8L ENGINE CAR HAS APPROX 100K (KILOMETERS) REASONABLY LOOKED AFTER. No obvious issues.
I WAS THINKING OF USING SUBARU UPPER ENGINE CLEANER TO CLEAN OUT COMBUSTION CHAMBERS, MANIFOLD,THROTTLE BODY. I DON'T WANT TO CAUSE ANY FURTHER ISSUES( Eg: damaged 02 sensor or clean up too good and cause oil consumption issues)
Is this stuff safe to use? Should i use or leave it?
Also, im planning on using a oil flush (Nulon). Is this stuff really needed
Thanks
