Early on, some of the Pentastars had issues, but they have more than proven themselves with FCA's updatess and fixes. You know, I was researching a new vehicle recently (have not purchased yet) and it suddenly dawned on me that the Pentastar is one of the ONLY engines left that is still N/A and does not have Direct Injection. Not sure how long this will last, but very interesting for those who want to avoid long term issues that some TC and DI engines have for long term ownership.I bought a 2020 Grand Cherokee with the 3.6.....sure i had rather have the 5.7 v-8 but not willing to pay 40k etc....I got a great deal on this one at 31k for a Limited.
Ive been a Ford guy most all my life ....had 4 Mustangs v-8's but I just dont like the 2.7 ecoboost in an Explorer.....not a fan of small engines with a turbo cranking out huge HP numbers in very heavy SUV's and trucks.
Most all my friends say the 3.6 is junk and will never make 100k miles etc......should have bought Ford or Toyota...
I dont see Jeeps or Dodge etc.....with 3.6 \'s littering the side of the road.
With proper oil chances the Pentastar should make 200k easy......question is my friends Jeep GC 3.6 says use 5w20.....two years later mine says use 0w20 .....I live in a very hot climate and will keep on using 5w20 Valvoline syn in my Jeep .....It sure seems to run better and smoother with 5w20 vs 0w20 in the summer months.
What is diff from the 2018 3.6 to 2020 to make Jeep change the the oil viscosity?
