Hey all, first time posting. Looking at purchasing a 2011 SC 4x4 that has the 3.7 does anyone have any history or advice when the miles get this high? Thx

I know this thread is old but I now have 150,000 miles on a 3.7 without ever going into the engine. It still runs great. the secret to long life is quality engine oils and filters at reasonable mileage intervals. I use high octane gas from leading suppliers for the extra horsepower and cleaning agents they give. I finally had to change the sparks at 145,000 miles as the gap had grown to 74-75 thousand and started to skip under load.
