To 6.4 hemi owners
I was thinking about getting a '15 Ram with the 6.4 , but it states premium unleaded. The "14's used 87. It would not be worth to use premium over diesel for me. What is your opinion on this ?

My owners manual has less than 300 pages.
For the 5.7 and 6.4 engines it says "87 octane acceptable-89 octane recommended.
