2025 Chevy 2500 HD
6.6l gas engine great Allison transmission transmission.
Not my personal truck just a fleet truck I picked up brand new for a project on the North Slope of Alaska.
I run this truck everyday. Plug it in when I sleep and remote start it when I wake up for my comfort.
Temperatures have ranges from -35 to 5 above zero averaginin the -20 range.
Well over 600 hours in this new truck I picked up at dead horses airport on January 24th.
Change oil reminder from the Oil life monitor kicked on in less than 30 days of operation.
Less than 1900 miles on vehicle for first oil change.
I would consider this severe service with real cold starts, idling like a patrol car and continuous use of 4wheel drive.
It’s my second office. Besides idling and putting at low speeds down an ice road to worksites it gets about 35 miles round trip to camp and back daily at 30 mph. With slowdowns for equipment and wildlife it is 38 minutes each way.
Out was factory dexos 0w20 I assume.
In Delo 400 XSP 5w40…it’s what we have
as we run heavy equipment. All fleet oil in real life severe application.
Oiler is doing the oil change in the light duty tent at this moment.
