Welcome. Great bunch of knowledgeable & helpful guys here. That is a great deal on the oil change but watch the fuel filter change some dealerships gouge you for that. If so it’s an easy 5 minute job with a creeper and a large baggie or wide mouth coffee can to stay clean. My warranty was 10k oil 30k fuel filter. My dealership always charged me $125 for an oil change.
I use mine commercially towing TTs & boats. 371k when mine pushed a head gasket low on coolant. Which coolant level is something you should watch as these tend to get EGR cooler leaks. Thanks EPA. Anyway 214k since with only issue being a load of dirty fuel. GDE ECM & TCM tunes have been money well invested for my truck. Enjoy
