you can use whatever you want. You don't have the turbocharged 1.4, so normal oil will be fine. I recommend that you at least use a synthetic blend type so you can go 5,000 miles between changesJust got my 2016 2.4 Renegade Latitude 3 weeks ago. Just wondering what type of oil should I use. It doesn't say synthetic on the manual but the dealer says use syntetic.
