What to Look for While Buying Oil for 7.3 Powerstroke Engines

best oil for 7 3 powerstroke

Now that you already have the best of the best in the market, which one of the 8 will you choose? To help you narrow down your choices, we’ve come up with a guide.

Fully Synthetic/ Synthetic Blend

Before anything else, let us give you a quick summary of what these are. Fully synthetic oil is a pure formula. It is not mixed with anything. On the other hand, a synthetic blend is mixed with other oils.

If it’s a battle between fully synthetic and synthetic blends, we will side with the fully synthetic oils.

Attention to Details

Admit it; we don’t always read the labels. It could be any product – oil, perfume, noodles, whatever – we find very few consumers reading the labels.

Most oils are engineered to be compatible with both diesel and gasoline engines. Yes, this is true, but not all the time, which brings us to what we were saying earlier.

Read the labels. Make sure that the oil that you got in your hands is suited for the type of engine you have at home.

Depending on the fluctuating temperatures and differing weather conditions, some oils may thicken or become thin. With this in mind, how do you choose the oil that’s right for you?

This is pretty easy. All you have to do is to check on the SAE weight of your oil. The weight is always written as NW-NN. N corresponds to a number, while W is for winter.

All you have to remember is that the lower the number beside W, the better equipped the oil is for freezing temperatures. The two other numbers tell you how well the oil performs when temperatures start to rise.

What you will be looking for is a higher number. The higher the number, the better equipped the oil is in warmer climates.

Top Brands on the Market

Most manufacturers would tell you how much of a treasure their engine oil is. We understand this can be overwhelming and confusing, especially if this is your first purchase.

But like in any product, some brands excel at making them better than others. When it comes to 7.3 Powerstroke oil, you got to trust it when what you have is from Liqui Moly. You can also never go wrong with Schaeffer or Valvoline.

But while pricier than the others, Shell is the ultimate brand when it comes to oils. Nothing beats that brand!
