The 1996 Ram V10 is an incredibly powerful and reliable vehicle, but it's not the most fuel efficient. On average, a 1996 Ram V10 gets around 10-12 miles per gallon in combined city/highway driving conditions. This isn't great compared to other vehicles on the market today, however it can be improved upon with some modifications and improvements made to enhance its efficiency. For example, installing better spark plugs and air filters can help reduce friction and improve combustion efficiency for increased gas mileage. Additionally, adding a cold air intake system can also improve airflow for better performance under load as well as give you slightly better MPG when cruising along highways or back roads alike. In short, if you're looking for maximum power from your 1996 Ram V10 then don't expect too much in terms of fuel economy - but with a little bit of modification here and there you should be able to squeeze out more than what is expected from this classic truck!
