Shell Rotella T5 Synthetic Blend 15W-40 Diesel ulje
The best engine oil for the 7.3 Powerstroke is Shell Rotella T5 Synthetic Blend 15W-40 Diesel oil. Here's why it's the best:
- Reliable engine cleaning
- Low ash formula
- Good value for money
7.3 Powerstroke engine Ford trucks prefer 15W-40 viscosity. It meets the engine's requirements and works in all climatic conditions.
Shell Rotella is a popular choice for truck owners, so this T5 Synthetic Blend diesel oil is also a popular choice for 7.3 Powerstroke engines. This is a heavy duty oil that thoroughly cleans engine pistons.
It also meets low emission requirements for almost all US manufacturers. This basically means that it will help reduce the carbon footprint of your vehicle.
This oil is ideal for easy cold starts, so it will work well even in sub-zero temperatures. Whether you use the truck normally or lift a lot of heavy stuff, this will be great either way.
It can withstand high temperatures and stress, making it ideal for commercial trucks. It also provides much better wear protection than conventional oils due to its synthetic base.
Model overview
The Powerstroke 7.3 has been hailed as one of the most reliable diesel engines Ford has ever produced. Launched in 1997 to replace the 7.3 IDI engine, it was a complete overhaul in terms of design and performance.
It is a turbocharged direct injection V8 diesel engine based on the T444E engine. The Powerstroke engines in Ford's F-series trucks made them the best-selling diesel trucks of their time.
The engine lasted until 2004 when it was finally taken over by the Powerstroke 6.0 due to increasing demand for lower emissions and higher fuel consumption. Still, it's one of the best diesel engines in pickups and you can still see it after all these years.
The oil type of the 7.3 Powerstroke is 15W-40, which has remained the same throughout all the years of production and is the rule. However, other viscosities are compatible with it and are used by many owners.
The diesel engine has not undergone any significant changes over the years that would require a different oil weight. Thus, the specifications of the maintenance product remained largely the same for all models that used it.
Oil for 7.3 Powerstroke recommended by the manufacturer
The easiest way to find the best oil for your car is to check its owner's manual. For trucks with a 7.3 Powerstroke engine, the recommendation may vary, so check your truck model manual.
The recommendations are the same for models of the same generation. Here's what Ford recommends in 2010instruction manual:
Degree of viscosity
Ford recommends SAE 15W-40 and SAE 10W-30 viscosities for the 7.3 Powerstroke engine. However, it also contains a chart on viscosities and temperature conditions.
While 15W-40 and 10W-30 diesel engine oils are preferred, 5W-30 and 0W-30 thinners are acceptable for subzero temperatures.
Capacity
The 7.3 Powerstroke engine requires 15 liters or 14.2 liters. You can refill the entire engine with three 5 liter bottles.
Oil specification
Since this is a Ford engine intended for Ford applications, the recommended engine oil for the 7.3 Powerstroke is Motorcraft 15W-40 Super Duty or Motorcraft 10W-30 Super Duty. Ford engine oil specification number is WSS-M2C171-C, CH-4/SJ/SH.
You can use another brand of oil that meets these Ford specifications. It also states to avoid category designations: SG, SH, CE, CF-4 or CG-4.
Approved by Ford
Oil for 7.3 Powerstroke according to mileage
Let's also take into account the mileage on the odometer, since this engine is present in trucks older than a decade and a half. If your engine is showing signs of wear, you may want to get something extra strong to clean out deposits and seal the engine.
Regardless of mileage, the Shell Rotella appears to be aa popular choiceamong Ford truck owners. However, owners also use other brands such as Mobile and Royal Purple, so Ford's Motorcraft doesn't seem to be as popular.
For trucks with high mileage, users recommend using asynthetic or synthetic blendin any compatible brand, but they don't actually list any viscosity specifically for high mileage trucks.
Ford trucks with the 7.3 Powerstroke can easily give you over 300k miles, so the high mileage benchmark for these trucks is higher than the standard 75k.
Users also recommend changing the engine oil and filter every so often5000 milesfor high mileage trucks to keep them running great.
| Low mileage | Under 100,000 miles | 15W-40, 10W-30, 5W-30 | Shell Rotella, Mobil 1, Motorcraft |
| High mileage | 100,000 miles or more | 15W-40, 10W-30, 5W-30 | Shell Rotella, Mobil 1, Motorcraft, Royal Purple |
An important note
If you are in sub-freezing temperatures, you should opt for a lighter weight diesel oil, especially for high mileage trucks.
