Looking to see what kind of motor oil guys have been favoring for these motors and what kind of service intervals have been doing.

0 Mack Technician Posted September 29, 2019 Share Posted September 29, 2019 Mobil Delvac 15W-40 1300 super is the oil Mack relabeled as “Bulldog”. Good oil. Far as intervals is concerned....you need to walk through the description page of your Mack maintenance book and see what service bracket best fits you. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/59103-oil-brands/#findComment-433022 Share on other sites More sharing options...
