Im dont entirely undurstand all of the oil rating and tried to find info about mystic but not to much. I was just wondering if I can increase my OCI on a 97 dodge cummins with the mystic its semi-synthetic or is the delo 400le equal OCI and such. There is a guy from my work that can get schaffers 9000 5w-40 for $120 for 6 gallons. I pull a 12,000lb chipper in the summer. Also the chipper is a oil cooled deutz diesel. I just want a good oil for year round for a fair price i guess. Sorry to ramble. thanks in advance for any advice.
