I just purchased a used 455 that has almost 1000 hours. Currently it uses john deere 15w-40 oil, but being that I am obsessed with synthetic oils, I want to switch it to a syn. However, I can't find anything that I know is full syn at a normal retailer that is 15w-40. But, I did find Rotella 5w-40, that had all the Deere, and Cummins, and Detroit approvals. Also, is Delvac a full synthetic oil? So, if I can't find 15w-40 would it be ok to use 5w-40 rotella, or should I just not change it and use dino, or is delvac 15w-40 a full synthetic? Any suggestions would be appriciated.
