Yikes!
Anyone with a Forced Induction engine or any type of GDI going more than 7500 miles on an oil change is just asking for it down the road. I know here on BITOG people debate over silly things, but I have seen with my own eyes the carbon build up and how oil breaks down in GDI motors.
The German brands that have GDI and turbo at least spec an oil better suited. Meaning their "European" formulas mainly using "heavy" 30w or using a 40w oil will help with the fuel dilution issues of these type of motors.
As for my Hyundai Sonata (2012) after the new engine installed in 2015 under warranty, When they had my engine apart I looked in it. The engine was clean per se, the valve train was spotless (Castrol Edge EP 5w30 every 5k miles) but the valves and piston tops were gunked up pretty bad.
I keep telling people. Oil is cheap. Change it more often. Cars now a days aren't as simple as they once were. Now with all the VVT, VTEC, and all that, why do you feel stretching your oil as far out as you can to save a few bucks is worth more than your engine down the road? It just boggles my mind.
Now I wait to be bashed by people that don't own a GDI car. haha. Or the ones that do, but have not had any issues yet......Let it commence.
I've decided, I don't really know what I don't know.
