Features and Factors to Consider When Choosing The Best Oil for Ford Diesel Engines
One of the gravest mistakes you'll make is to feed substandard oil into your engine. Fuel consumption and maintenance cost will considerably increase in the absence of good quality oil. Besides, you may end up ruining your vehicle's engine when you use substandard oil. Thankfully, 6.7 Powerstroke diesel engines are not too selective when it comes to diesel oils. Here are the features and factors to pay attention to before choosing a synthetic oil for Ford 6.7 Diesel.
Viscosity is a measure of an oil's thickness. It may seem inconsequential, but it does affect the functionality, as the resistance to the oil's flow is dependent on the level of viscosity. For Ford 6.7 power stroke engines, we recommend 15W-40, but 5W-40 is the more versatile viscosity, as it gives a wider range of operating temperature for the engine oil.
While we have exclusively selected synthetic diesel oils, there are other composition types available. It would be best if you went for a fully synthetic oil - maybe with additives. Synthetic blends are a mixture of different oils, and they could contain impurities that will significantly shorten the lifespan of the oil.
Diesel engines differ significantly from gasoline engines in their interior structure. Thus, it is essential that the oil you choose has an additive package specific to your diesel engines to prevent rapid wear. Nonetheless, you should choose one that has a strong additive package so it can effectively combat soot, deposit, and sludge buildup.
Lubrication is one of the essences of applying engine oils. The friction that arises from moving machine grinding on each other causes gradual wear and tear. Check the API classification on any oil and establish the manufacturer's standards it meets up to before you buy.
Contemporary 6.7 Powerstroke engines come with upgraded emission systems, quite different from those in older models. You have to check an oil's compatibility with your engine's emission facility. Usually, the oil's suitability is specified in the manufacturer's information/recommendation.
What Kind of Oil Is Best for 6.7 Powerstroke?
Synthetic oils are the better option for 6.7 Powerstrokes, fully synthetic oils, more preferably. The relatively newer internal working systems require improved formulations apart from the typical standard oils used in older engines. To efficiently manage the extreme heat, deposit buildup, and wear in 6.7 Powerstrokes, go for full synthetic or synthetic blends.
Step by Step Guide on How to Change The Oil in 6.7 Powerstroke
We don't recommend changing the oil yourself if you don't have experience changing vehicle oil, as it could quickly become messy if you're not sure of what you're doing. Nevertheless, if you're sufficiently handy and adequately prepared, you can get it done in no time. Here's how to go about it.
Prepare the truck
The first thing to do is park your truck on an even and leveled surface. Secure the truck in the park option. You may want to warm the engine for a bit to make the oil more fluid. However, it is not compulsory, and you should be careful not to get hot oil on your body
Drain the old oil
After you might have secured the truck in the perfect location, the next thing to do is undo the drain plug and get the old oil out. Find the drain plug on the low part of the oil pan. The drain plug can be hard to undo at times, but with enough effort, you should be able to undo it with some effort. Fully unscrew the drain plug and let the oil drain completely into the drain pan.
After the oil has fully drained, you'll have to screw the oil drain back in. Ensure you fix back the o ring so it'll stay in place. You should also pay attention not to overtighten the oil drain.
Remove the oil filter
With your oil filter removal tool, lose the oil filter until you notice the oil coming out from the top. Remove the oil filter. However, you should let the remaining oil drain dully before removing the oil filter to avoid making a mess.
If you notice that the old rubber gasket sticks to the filter housing after removing the filter, be sure to remove it before moving on.
Fill the new filter with oil and install
The only way to ensure that oil gets to the vital lubrication points and prevent quick wear is to fill the new filter with new oil. If this is not done, you'll be surprised at the wear rate after a few times of use. Additionally, you should also lubricate the rubber gasket that comes with the new oil filter to reduce or even eliminate leaking risk. After filling with oil, hand-tighten the filter or use an oil removal tool.
At this point, you want to check if there is an oil leak on the filter or the plug. Wipe the plug and new oil filter clean and check for any apparent oil leak. If there is none, you can move on with the oil changing process.
Fill with fresh oil
You can now fill the engine with the new oil. However, check the oil level as you fill and ensure that you don't overfill. Replace the cap when you're done, and test start the engine. Run the engine undisturbed for some minutes and check for any leaks under the truck.
