My number 6 injector went out about 2 months ago and I had to replace . Two weeks ago my number 6 did also. Dealership said after 50000 miles it is time to replace them. I changed to migrade gas at about 60000 miles . I have 83000 miles on my 2021 ram 1500 limited with e torque. Do you think that could be contributing to failures as well?
