Re: Oil change when towing an RV
I also tow with our JGC Diesel and I did have an oil analysis done at 8500 miles (when I did my second oil change at 15k). Blackstone said the oil was still OK BUT.....I've decided to do my regular oil changes at 7500 miles as this would coincide with the tire rotations.
I'm a bit anal and, for me, its cheap insurance. If this is your first oil change, I would go ahead and do it anyway at 6k. I did my first oil change at 6500 miles as this would be the factory fill and probably has a lot of metals in it. This is quite normal.
