I have a 2014 Dart that uses 0W-20. What is the motivation to not use that grade? 0W-20 is readily available, my local Meijers store has Mobil 1 in that grade in 2 choices, the regular with a green cap and extended performance which is supposed to be good to 15,000 miles. I've used both in my car but when I used extended performance I still changed it at 7000 miles as I don't think FCA approves of extending the oil change interval.
And 0W-20 the same price as the other Mobil 1 grades.
With a $5 off coupon last weekend, I paid $21 and change for a 5 qt jug of the green cap stuff!
My '09 Challenger R/T uses 5W-20, and I noticed they say you can use 0W-20 in the hemi, so I am debating if I should use 0W-20 in both of those cars.
