oil capacity 2018 jeep 3.6

6 quarts of 5W-20 (Preferred per Mopar) or 5W-30 (depending on the temperature range anticipated before your next oil change)

The above is incorrect for the 2018 3.6l, it is 0w 20, the 5.7 is 5w 20.

Another answer never use an oil more than 5w 20 for a 5.7 hemi with MDS. It will cause a defect in the MDS system.

so how many quarts of ow 20 does the 3.6 take

0W20 is a synthetic oil I believe. Still 6 quarts.

Yes 4.9 quarts.just had it done makesure whoever changes oil tightens the filter fown properly Walmart didnt in my daughters new jeep and she drove with oil running all over 3ngine and eventually driving with 0 oil in her grand Cherokee.
