I have a 2015 ram1500 5.7 hemi and I've noticed a big drop in my fuel mileage. I was getting around 20 to the gallon and now I'm getting 16 on a good day and around 14 on a bad day. Anyone have the same problems and know any ways to fix it?

 

How many miles on the truck?

 

Last tune up? Been buying gas at the same place? When did the drop happen? Have you checked for:

• Dragging brakes
• Underinflated tires
• Air intake obstruction
• Exhaust obstruction

Need to provide much more information before we can begin to suggest "any ways to fix it". (It may not be broken).

 

Change the air filter, change the spark plugs?
