Hi again Rhinebeck, you’re like a professor in here! All kidding aside I do respect your knowledge and help in this forum.@Amaruq
Not mandatory, but a 3.6 owner that is doing his/her own oil changes, probably should have one of these on the garage shelf all the time.
The cap is known to crack so, it is cheap cheap insurance ($15.00) to have one on hand.
--A month or so ago, I even had a local tech call and ask me if he could have my new spare cap as he could not get one right away and he had cracked a cap on a clients Jeep. The tech knew I kept a spare as we talk/brain storm pretty often. He borrowed and replaced it with a new one a week later.
Great idea about just keeping an extra oil filter cap which brings me to my 2nd question of the day.
I went to the Amazon site to buy that filter cap and there was a notice that said “ this will not fit your 2019 Jeep Wrangler”. Should I just buy one from the dealer?
