Rotella T5 is a synthetic blend, T 6 is full synthetic oil, I prefer full synthetic oil over a blended oil and have for the past 25 years, some people report a small increase going from dino to synthetic, but your right foot has the most control over your fuel mileage...

And if using 5w40 it has to be full synthetic according to the manual

I just changed my oil and used the Valvoline full synthetic 10W30. (10,670 miles, 95% highway). It would have been 1 year on the 10th. The oil filter is a premium Mobil-1. It was asking for the oil change and fuel filters as well. I ordered the Mopar filters from Geno's. I re-set for the oil change, but I could not find anything for the fuel life re-set. Any info out there? Thanks! JD

Its the same to reset the fuel filter just hold the right arrow on the fuel filter page to reset

My 'vehicle info' does not take me to the fuel life re-set. I did do the filter replacements and it is a bit more tedious than my 07.5 I guess I will have to go to the stealership to see about the re-set. Thanks. JD

When on the filter life page just hold the right arrow it will ask you if you want to reset the filter life
