mackr74 Posted November 6, 2023 Share Posted November 6, 2023 How many gallons of oil does the 865 v8 mack hold with filters Quote Link to comment https://www.bigmacktrucks.com/topic/73509-oil-capacity/ Share on other sites More sharing options...
JoeH Posted November 10, 2023 Share Posted November 10, 2023 If it's like the endt676 engines, then how many oil filters you have tells what size oil pan you should have. My one truck holds 14 gallons, but that one has the biggest oil pan/filter arrangement Mack made.one of my others is around 9 gallons I believe. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73509-oil-capacity/#findComment-541720 Share on other sites More sharing options...
mechohaulic Posted November 10, 2023 Share Posted November 10, 2023 I never knew the relationship between oil pan size and number of oil filters. for a while Mack had the huge oil pan total was 31 qts ; 3 filters ??

JoeH Posted November 10, 2023 Share Posted November 10, 2023 3 oil filters is the ESI+ (extended service interval plus) and had a 56 quart capacity, with a 25,000 mile oil change interval. ESI was 27 qt pan with 2 oil filters. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73509-oil-capacity/#findComment-541730 Share on other sites More sharing options...

mechohaulic Posted November 11, 2023 Share Posted November 11, 2023 I may be "out in left field " with this ;hopefully someone will correct me. 1-the super large oil pans had a situation with hairline cracks developing in the casting . vaguely remember pulling down the tubs fining cracks near the middle reenforcing braces, 2- when the three oil filter set up FIRST showed up , was not the rear filter an internal spin/scrapper filter unlike the other two ?, I know the scania had the spinner /scrapper filter. as stated before these forums get the dormant brain cells moving.

JoeH Posted November 12, 2023 Share Posted November 12, 2023 1, stamped not cast; I couldn't say, my 79 has had thr sane pan forever. I have had a smaller pan crack pretty bad in a couple corners. 2; my 79 ESI+ has 3 filters, no spinner. My late 70's early 80's ESI engines have 2 filters. My 1995 and 2003 ESI engines have the spinners Quote Link to comment https://www.bigmacktrucks.com/topic/73509-oil-capacity/#findComment-541844 Share on other sites More sharing options...
