Oil change
Have a Winnebago Tour with a 450 Cummins Diesel engine. Getting ready to change the oil for the first time and was wondering what type of oil to use. Not sure what was used in it at the factory?? Anybody have a Cummins and can give me some suggestions or no what was used in their coach. Thanks

Shell Rotella 15w-40 is very popular. Gallons usually available at Walmart for a good price.

After I bought my coach in 2008 the first place I took it was to Cummins for a full service and inspection.
They used Valvoline Blue, which is recommended by Cummins.
Valvoline™ Premium Blue™ 8100 ES Heavy Duty Diesel Engine Oil: Heavy Duty Products - Valvoline®
It has the Cummins endorsement and logo right on the front.
I keep an eye out and buy when on sale, usually Autozone had a sale 2 times per year and I buy for ~$13/gal

I'm on diesel number four, and have used Rotella in all. I buy it by the gallon case at Sam's.

Call Cummins Care at 1-800-343-7357 with your engine serial number and ask them.
IMO nobody knows what's best for your particular Cummins engine better than Cummins.

Either or is just a good as the other. I use Valvoline Blue 15w-40 but Shell Rotella is just as awesome.

X2 on using the same oil in the generator - do it at the same time. This way you only have to buy and carry one type of oil around.

Shell Rotella for both Cummins and Onan. Walmart usually has the best price.
