As the miles build up on my engine, oil consumption has gone up.
I have always monitored. Always change oil at 5,000.
Same with my older cars. but those dont use oil.
The 2010 now uses 2-3 qts every 5000 miles. (now at 152,000)
my 2013 with the 3.6, now at 86,000- shows sings of using a little bit of oil.
Ive also read in other places- that oil usage on the 3.6 will happen as the engine racks up the miles.
Ive wondered----could it be that carbon buildup is ocurring- and you get pieces of carbon- from say the top of the valves- break off and make it into the cylinder where it bounces around-- and scratches the cylinder walls
or you get carbon buildup- and you then use a carbon cleaning agent in the fuel- and it cleans/breaks off small pieces of carbon that then scratch the cylinders?
Its something Ive been pondering for a while. Is it true? I dont know.
As Ive seen the oil consumption slowly increase as the engine gets older.
