Ford 8N engine oil capacity

To begin, we must determine how much engine oil a Ford 8N requires.
Your Ford 8N engine holds 6 quarts of oil. Be sure not to mix up your
engine's displacement
(or its size) with its actual capacity. The displacement of each engine cylinder is the quantity of air and fuel drawn into it. In contrast, the oil capacity is the amount of oil necessary to keep the engine running correctly. If you don't realize the difference, you may significantly underfill your engine, resulting in severe engine damage.

What kind of oil does a Ford 8N need?

After determining how much oil your Ford requires, it's equally important to select the appropriate type of oil to use—and there are countless options to choose from.
Don't worry, we've got the primary oil you're looking for: 10W-30 engine oil. This is the oil recommended in your owner's manual, and we're not one to argue with the manufacturer.
Let's break down this oil type further so you know what you're putting in your truck. The "W" stands for winter, and the 10 preceding it indicates that this mix has a low viscosity (thickness) when the engine is cold. The 30 after the "W" denotes its moderate viscosity while the engine is heated and working.
If you want to weigh your options, we recommend the following oils:

How often to change oil on a Ford 8N

To protect and extend the life of its engine, Ford advises changing the oil every 7,5000 miles or every 100 hours of use.
Checking your oil level regularly and keeping track of your last change might help you avoid going too long without a new
oil change
. Even if you don't use your tractor much and keep your mileage low, you should replace the oil every six months to protect it from becoming sludge.
  • Your engine is making unusual noises
  • You detect smoke or burning odors under the hood
  • You notice a decrease in your car's performance
  • You see dark and/or gritty oil 

How to change your oil and oil filter

Now comes the most important part: it's time to change the oil! Make sure you have a socket wrench, a drain pan, a filter wrench, a new filter, and a rag before you start. The last thing you'll need is a new bottle of 10W-30 engine oil!
Start your engine and let it run for a while to warm up the oil. This will make it easier for the oil to flow. After a few minutes, shut off the engine, open the hood, and do the following:
  • Remove the oil fill cap
  • Take out the bolt and washer from the oil drain in the bottom of the engine, and pour out the used oil into the drain
  • Remove the used oil filter and let the oil drain
  • Insert the new filter
  • Install a new washer on the oil drain bolt and tighten it to 29 lb.-ft.
  • Add the new oil and replace the fill cap
If you follow the steps we just went over, you should be good to go! Your final step is just cleaning up. Put the used motor oil in a sealed container and drop it off at your local recycling facility.
