I know bringing up anything to do with oil is not the best subject but I have to ask. While out on a ride today I decided to check my motor oil on my 2011 Road Glide Ultra. Sure enough it was down a quart. Finding oil for a Harley Davidson up here in my neck of the woods is not an easy thing to do. Today being a holiday it was worst. Anyway I find some Rotella t 15w40 full synthetic for big trucks and tractors so I dumped it in the motor. I am thinking Jesus it can't be the end of the world it's heavy duty synthetic oil.
Thoughts on this bad or not so dad idea. I rode for about three hours after this in some real heat. I didn't notice any strange noises in the motor.
Here are the specs:
API, CK-4, CJ-4, CI-4 PLUS, CI-4, CH-4; ACEA E9, JASO DH-2,
MA/MA 2; Caterpillar ECF-2, ECF-3; Cummins CES 20086; DDC
DFS 93K222; Deutz DQC III-10 LA; MACK EOS-4.5; MAN M3575;
