Found this on a FB group, thought I'd share it. Who doesn't like good tear down pics?
Background:
"2012 Cruze Eco 1.4L Turbo. This car has seen nothing but AMSOIL Signature Series 5W-30 since 2013, and has been tuned since as well, first with Trifecta then with BNR, making about 50hp and 70lb-ft more power *to the wheels.* Starting in about 2015, the car was used to tow my 14' boat as well as my utility trailer and various uhaul trailers. Since I started working from home full time in 2015, most of the driving was short trips, wide open throttle to redline daily.
At 72k miles, I pulled the cams to upgrade valve springs. The oil in service at the time of this disassembly had 12,500 miles and 2 years on it, about 1/4 of which was with a trailer behind it and the rest of it hitting max boost daily. I stopped caring about fuel economy once I stopped commuting. The oil change prior to that went 15,622 miles and 18 months, and all oil changes before that were at 10,000-15,000 miles (dealer drained it a couple times to service the oil pan and PCV system or they'd all have been 15k miles)."
