Looking to do an oil change on 3.6 Pentastar Wrangler in a couple days. Local store has M1 on sale for $30 (Canada) or Rotella Gas Truck on sale for $40. Either would be 5W20 and typical OCI is about 7 - 7.5k miles. Is it worth the $10? I can't seem to find the data sheet on the RGT either for some reason.
Thanks
