Model Overview

Ford’s Powerstroke 7.3 diesel engine is regarded as one of its most reliable. It was designed and built to replace the 7.3 IDI diesel engine.

This turbocharged, direct-injection V8 diesel engine is based on the T444E. They were the most popular diesel trucks in their day, thanks to the Powerstroke engines found in F-Series Ford trucks.

It was in service until 2004, when it was replaced by the Powerstroke 6.0 due to growing demand for more fuel economy and fewer emissions. However, it’s still one of the most powerful diesel engines on pickup trucks and can still be seen after many years.

15W-40 is the 7.3 Powerstroke oil type. This has remained constant throughout its production years. It is still in good condition. Other viscosities can be used with it, and many owners have tried them.

No significant changes in the diesel engine’s performance over the years would have required a different oil weight. Therefore, maintenance product specifications remained the same for all models.

7.3 PowerStroke Oil Type by Year

These are specific oil recommendations based on year and model.


The 1995 Ford F350 7.3 Powerstroke uses 15W-40 oil. However, 10W-30 is better for cold climates.

  • Shell Rotella Synthetic Blend 15W-40 Diesel Engine Oil
  • Shell Rotella Synthetic Blend 10W-30 Diesel Oil


The oil recommendations for the Ford F350 2001 model are the same. Depending on the climate or personal preference, you can choose between 15W-40 and 10W-30.

  • Shell Rotella Synthetic Blend 15W-40 Diesel Engine Oil
  • Shell Rotella Synthetic Blend 10W-30 Diesel Oil

FORD E450 OIL TYPE (1994-2003)

For its fourth-generation variants of the Ford E-450 truck, the 7.3 Powerstroke diesel engine was used. It was in use from 1994 to 2003. The engine was then replaced the next year. These trucks use the recommended 15W-40 diesel fuel oil.

  • Shell Rotella Synthetic Blend 15W-40 Diesel Engine Oil
  • Motorcraft 15W-40 Super Blend Diesel Motor Oil

Oil for 7.3 Powerstroke per Mileage

Also, let’s not forget about the mileage since this engine is only used in trucks older than ten years and a half. You may need to buy something stronger to clean and seal your engine if it shows signs of wear.

Shell Rotella is a very popular choice for owners of Ford trucks, regardless of their mileage. However, Ford’s proprietary Motorcraft seems less popular than other brands such as Mobile and Royal Purple.

Users recommend high-mileage trucks using a synthetic blend from any compatible brand. However, they don’t specify any viscosity for high-mileage trucks.

Ford trucks with the 7.3 Powerstroke engine can easily cover 300k miles. This makes them more efficient than standard 75k.

High-mileage trucks should also be filtered, and oil changed every 5000 to ensure they run great.

Things to consider when oil is used for the 7.3 Powerstroke

This is everything you need before purchasing engine oil for your diesel truck.


Fifteen quarts is the 7.3 Powerstroke oil tank capacity. Again, this capacity does not change based on the year or model of the truck with this engine.


Ford recommends that oil be changed every 200 hours. However, it is difficult to determine engine hours, so the recommended intervals in miles are 5000.

Some people change their engine oil after 3000 miles. However, this depends on how often you use your engine. You should change your engine oil once every 5000 miles.


It doesn’t take much time or tools to perform the 7.3 Powerstroke oil changing. The instructions are in the owner’s manual. However, if you need more detailed information, a tutorial is better.

This video gives detailed instructions and information about the oil. We have already covered this topic in detail in this post.

The manufacturer recommends oil for 7.3 Powerstroke.

Checking your vehicle’s owner’s manual is the best way to determine the right oil for your car. The recommendation for trucks equipped with the 7.3 Powerstroke engine may differ, so check the manual specific to your truck.

These recommendations apply to the same model generation. Here are the recommendations Ford makes in the 2010 owner’s guide.


Ford recommends SAE15W-40 and SAE10W-30 viscosities on the 7.3 Powerstroke engines. It also includes a chart that shows the temperature and viscosities.

15W-40 and 10W-30 diesel engine oils are preferred. However, for sub-zero temperatures, thinner 5W-30 or 0W-30 oils are acceptable.


The 7.3 Powerstroke engine needs 15 quarts (or 14.2 liters). Therefore, three 5-quart bottles will suffice to refill the entire engine.


Because it is a Ford engine, the recommended oil for 7.3 Powerstroke engines is Motorcraft 15W-40Super Duty or Motorcraft 10W-30Super Duty. Ford’s engine oil specification number (WSS-M2C171-1-C, CH-4/SJ/SH) is

Oil from any other brand can be used if it meets the Ford specifications. You can also avoid the following category designations: SG. SH. CE. CF-4.
