Ideal interval for an oil change in 6.4 Powerstroke

Before you go for choosing a certain oil type for your 6.4 Powerstroke engine, it is also a critical step to determine the exact oil interval change.

According to Ford’s experts, the recommended oil change interval lies between 5000 miles to 7000 miles. And it should be done every six months, ideally.

But there are no strict parameters defined for an ideal oil change interval. Because some vehicles run under normal operating conditions whereas others run under severe operating conditions. Therefore, the pressure on the engine becomes double or vice versa.

Normal or severe, operating conditions are an important factor in determining the oil change interval.

Unlike 7.3L and 6.0L Powerstrokes that use the HEUI system, a 6.4L Powerstroke uses a common-rail piezo injector that is great in reducing exhaust emissions.

Another interesting fact about 7.3L, 6.0L, and 6.4L Powerstrokes is basic fuel delivery system design in three is quite different. Unlike both versions of Powerstroke, a 6.4L Powerstroke injector operates between 42 and 96 volts with a single ECM.

If the piezo injector breaks down, you are left with the only solution to replace it at once. Yet it is important to know that with better fuel filter service practices, you can increase the lifetime of your engine.

So it is very much appreciated if you will maintain a good oil change service of your 6.4L Powerstroke.

To maintain the superiority of your Powerstroke, you can try a 4,000 to 4,500 miles oil change interval. Perhaps, it would be a fair deal in the long run.
