2021 Ford F350 Oil Type and Capacities

There are many versions of the Ford F350 between trims, engines, cab sizes, bed sizes, and additional packages.

There are only 3 different types of engine options for the 2021 Ford F350.

What type of oil does the 2021 Ford F350 take?

Ford recommends that the 2021 F350 6.2 L V8 and 7.3 L V8 take SAE 5W-30 oil (7.0 qt and 8.0 qt respectively). The 6.7 L Diesel engine takes 13.0 qt of SAE 10W-30.

	Oil Type	Oil Capacity	Filter
6.2 L V8	SAE 5W-30	7.0 qt	FL-820-S
6.7 L Diesel	SAE 10W-30	13.0 qt	FL-2051-S
7.3 L V8	SAE 5W-30	8.0 qt	FL-820-S

Read on for more information and specifications on each of these filters as well as the specific oil filters required for each.

Since these engines use 5W-30 you may also like Can you use 5W-20 instead of 5W-30? where I discuss the risks of switching these oil types.

The information taken for this article was taken from the 2021 F350 owner’s manual.

2021 F350 6.2 L Oil Type, Capacity, & Filter

The 6.2 L V8 engine in the 2021 Ford F350 takes 7.0 qt of SAE 5W-30 engine oil and the Motorcraft FL-820-S Oil Filter.

Ford recommends that you use the Motorcraft version of these two items, which I’ve found on Amazon below, but I believe as long as you choose to use synthetic blend oil with an appropriately sized oil filter, you should have no problems.

Ford mentions that for this engine, if you plan to run frequently at cold starts (or running at extremely cold temperatures) you should use SAE 0W-30. There doesn’t appear to be an easily available Motorcraft version of this, so I recommend Mobile 1 full synthetic as a replacement.

2021 F350 6.7 L Diesel V8 Oil Type, Capacity, & Filter

The 6.7 L Diesel engine in the 2021 Ford F350 takes 13.0 qt of SAE 10W-30 engine oil and uses a Motorcraft FL-2051-S filter.

Ford recommends that you use the Motorcraft version of these two items, which I’ve found on Amazon below, but I believe as long as you choose to use synthetic blend oil with an appropriately sized oil filter, you should have no problems.

If you plan to run frequently at cold starts (or running at extremely cold temperatures such as less than -22 F) you should use SAE 0W-40.

2021 F350 7.3 L Oil Type, Capacity, & Filter

The 7.3 L V8 engine in the 2021 Ford F350 takes 8.0 qt of SAE 5W-30 engine oil and the Motorcraft FL-820-S Oil Filter.

Ford recommends that you use the Motorcraft version of these two items, which I’ve found on Amazon below, but I believe as long as you choose to use synthetic blend oil with an appropriately sized oil filter, you should have no problems.

Ford mentions that for this engine, if you plan to run frequently at cold starts (or running at extremely cold temperatures) you should use SAE 0W-30. There doesn’t appear to be an easily available Motorcraft version of this, so I recommend Mobile 1 full synthetic as a replacement.

How often should you change your F350 Oil?

According to the 2021 Ford F350 manual, under normal usage conditions, the oil in your truck should be changed every 5,000 or every 6 months.

There is an oil change indicator system that should provide a guide as to when the oil should be changed. At a maximum, you should never change your oil with more than 10,000 miles or one year between changes.

Every time you perform an oil change you should also:

• inspect wheels
• rotate tires
• inspect and lubricate u-joints
