How to Choose Right Synthetic Oil for Ford 6.7 Diesel
It’s essential to feed the engine with high-quality oil, regardless of your vehicle’s type. Even the Ford 6.7 Powerstroke requires suitable fluid for proper engine function.
That’s where you need to pay attention while buying the best oil for 6.7 Powerstroke. The following factors should help you to make a successful purchase.
Oil Composition
Although we’re talking about synthetic, there are variations available regarding 6.7 Powerstroke oil type. A full synthetic oil features base oil with additives only.
But semi-synthetic & synthetic blend contains a mix of different oils. The combo contains impurities which may result in black, dirty oil for a change.
Viscosity Rating
It’s the measurement of fluid’s thickness which resists the oil’s flow. In fact, the operational temperature has a direct influence on viscosity.
For heavy 6.7 Powerstroke engines, 15W-40 is the most preferable standard. But the 5W-40 rating gives the most extended range of operating temperature for the oil.
Internal Protection
One essential role of engine oil is to reduce metal-to-metal contact or internal friction. Sufficient lubrication of moving parts can even cut short fuel consumption.
This fact largely depends on the ability of contamination control as well. You need to focus on its ability to meet/exceed certain standards for Ford 6.7 engines.
Additive Package
Diesel & gasoline engines have specified interior structure. And to prevent any unwanted blocking element, you should get fluid with powerful additives.
Stronger additive package is one major characteristic of good-quality oils. The effective formula resists & even disperses sludge/soot & deposit inside the fuel chamber.
Emission Control
Modern systems feature an upgraded emission facility that lacks in older engines. If your Ford 6.7 diesel is somewhat old, you have to check its compatibility.
Not to mention, the choice has to remain fully usable with your vehicle. Go through the manufacturer’s recommendation/specification to ensure the oil’s suitability.
