i just bought a John Deere 5103 new (being delivered today). I use Rotella in all my heavy equipment and diesels. Any recommendations for weight and type of oil for the new Deere? I commonly use 30W in my machines.
Your owners manual will specify the weight/grade of the oil to use. Not using the recommended weight/grade oil can void your warranty. and yes the Rotella should be fine as long as it is the right weight/grade.
JD 8320 MFWD, JD 6415 MFWD, FEL, and cab, John Deere MFWD 4600, John Deere 4020, John Deere 4430, John Deere 455 mower, Deutz, and Gehl 4610 perkins skidsteer
Deere will send you a coupon for free oil/filter for your first oil change on the 03. After that Rotella will be fine. Rotella exceeds specs that is required for JD. We use 15w40 in everything diesel.
