By trapping oil vapor before it can re-enter the engine, you ensure that only clean air is being compressed by your turbos.
The kit includes a heavy-duty steel bracket that mounts under the truck, making it very easy to drain during your regular oil changes.

Keeping your best oil for 6.4 Powerstroke inside the system is vital, and this part ensures your turbo stays lubricated without making a mess.
This APDTY line is built to the same specs as the original but uses modern manufacturing to ensure it lasts. It’s a direct fit, which means no fighting to get the bolts lined up. If you are doing turbo work, you should absolutely replace this line while you are in there.

Complete Buying Guide for Best Oil For 6.4 Powerstroke
Essential Factors We Consider
When you are looking for the best products for your 6.4 Powerstroke, you have to think about more than just the price. These engines have high-pressure common rail fuel systems and twin turbos, which means they are very demanding on their oil. We look for filters that have high efficiency ratings (25 microns or better) and tools that won’t damage your expensive plastic parts. If a filter can’t handle the soot, it will clog, and your engine will suffer. We also look for kit completeness—having all the O-rings and gaskets included makes a huge difference on a Saturday afternoon when you’re under the truck.
Budget Planning
Maintaining a diesel truck isn’t cheap, but you can save a lot by doing the work yourself. A typical dealership oil and fuel filter change can cost upwards of $400. By purchasing a complete kit like the GETOPAUTO or high-quality individual filters like Doc’s Diesel, you can cut that cost by more than half. Invest about $10 in a proper socket tool early on; it will save you from having to buy a $40 replacement cap later. Remember, spending a little more now on a catch can or a high-end filter is much cheaper than replacing a $15,000 engine later.
Final Thoughts
The 6.4 Powerstroke has a bit of a reputation for being finicky, but with the right maintenance, it can be a reliable powerhouse. The key is never skipping an oil change and always using the right filters. Whether you go with the factory Motorcraft parts or high-quality aftermarket kits, staying consistent is what matters most. Don’t forget to check your turbo lines and oil separator to keep the system running at 100%.
Frequently Asked Questions
Q: How often should I change the oil in my 6.4 Powerstroke?
A: Ford recommends every 5,000 to 7,500 miles, but many owners prefer every 5,000 miles, especially if they tow heavy loads or drive in dusty conditions.
Q: Can I use 6.0 Powerstroke filters on my 6.4?
A: Yes, the oil filter (FL2016) is the same for both the 6.0L and 6.4L engines. However, the fuel filters are different, so make sure you get the correct kit for your year.
Q: Why do I need a catch can?
A: A catch can traps oil vapor that would otherwise go into your intake and turbos. It keeps your engine cleaner and helps prevent power loss over time.
Q: Is billet aluminum better than steel for the filter socket?
A: Yes, billet aluminum is lightweight and very strong. It is less likely to round off or slip on the plastic caps compared to a heavy steel socket that might be slightly oversized.
