Older Dodge trucks with carburetors had more frequent tune-up needs (often every 6,000-12,000 miles). Modern Dodge trucks with fuel injection systems have much less frequent needs. Many newer trucks may only need a tune-up (if one is even needed at all) every 100,000 miles or more.
Instead of focusing on a mileage-based schedule, it's better to follow the maintenance schedule outlined in your owner's manual. This manual will specify the recommended service intervals for your specific truck model and year. It will detail when to replace spark plugs, air filters, fuel filters, and other components.
If you're experiencing performance issues like decreased fuel economy, rough idling, or misfires, you should take your truck to a mechanic sooner rather than later, even if you're not due for a "tune-up" according to the manual. The mechanic can diagnose the problem and recommend the necessary repairs.
