Another oil report on my 2012, built in early fall of 2011. 5.0 non R-Spec. I have detailed results from different oils in the past. Have used synthetic since first oil change at 3-4k. Been a big Mobile one fan for decades. Put on 5-20w extended drain, no oil consumption at 3500-4k when changed. Kendall Titanium 5-20w full synthetic same result same mileage range. One oil change with dealer installed Plain Mobile One full synthetic 5-20w, quart down at 3500.
I have 2500 miles on my first Pennzoil Ultra 5-20w synthetic (Ultra recommended by many owners), no oil consumed
I have used both cheapie looking OEM filter and the one with the better fitting ends. No difference.
Mix of 30 percent miles in town, rest on highway 60-80mph. I will blow out exhaust once a tank full with full throttle run to redline in multiple gears (the GDI is set way too rich and visible crap (not blue or oil) comes out. I do gentle hyper mile with the right foot unless challenge by Achtung mobiles, rice burners or GM ponies. Then they get to see Genny taillights.
Bought this new in March, under 20k miles at the moment. Ran GDI chemical valve cleaner at 11k, scope showed very little on valves, none after. Posted report on that. Seems like no PCV problems that could cause oil to be lost. GDI does not clean intake valves with gas.
100% Shell, BP, Marathon premium. And stations with high volume sales, fresh premium.
Maybe I am lucky so far. Especially with the type of driving has not shown any defects, YET..
