When it comes to the best oil for 5.7 Hemi or any high-performance engine, you must go through the viscosity.

Viscosity is how much the oil thickens according to the temperature. For this, you have to go through the SAE weight. Your selected oil should be suitable both in colder and hotter temperatures.

Oil Types

There are conventional oils for the motors, and there are also synthetic oils for the engines. If you narrow it down, you will find four different oils for the vehicle engine. They are conventional oil, synthetic oil, high-mileage oils, and synthetic blend oil.

Before you get a specific oil for your Hemi 5.7, go through the label on the oil. The oil containers usually include labels of the details on them.

From the oil type to the other specs are written there. Also, all oil will not go in every car. So, you will see the car type there too. Go through it and know if it’s right for you or not.


Another fact you need to be careful about is the suitability of the oil according to your requirements. Here, remember that if you have a gasoline engine, you can go for synthetic oils.


Also, the owners of diesel engines can settle for synthetic oils. But there are some cases where you cannot use synthetic oil at all! Look at the matter carefully. Don’t worry if you are a Hemi 5.7 owner because you can use synthetic oil!

However, you must ensure that you are using synthetic oil consistently. Also, you have to change it after a specific interval. Synthetic oil will protect your engine and also run it correctly.


Is synthetic oil better?

Can I mix synthetic oil with regular oil?
