You might be wondering if you can put 87 in a 5.7 Hemi engine. The answer is yes, you can. However, there are a few things to keep in mind before you do so.

First of all, make sure that your engine is compatible with the type of fuel you’re using. If it’s not, then you could end up damaging your engine. Secondly, 87 octane fuel has a lower energy content than higher octane fuels.

This means that it will burn less efficiently and could lead to decreased performance from your engine.

  • Remove the negative battery cable from the terminal
  • Unbolt the four bolts that secure the air intake duct to the throttle body with a socket and ratchet
  • Pull the air intake duct off of the throttle body
  • Unplug the mass airflow sensor wiring harness from its connector on top of the throttle body
  • Remove the two bolts that hold down the mass airflow sensor with a socket and ratchet, then pull it out of its housing on top of the throttle body
  • Insert a flathead screwdriver into one of the small holes in each side of the new 87mm throttle body, then rotate it counterclockwise to loosen and remove both butterfly valves from their housings inside 5the7 hemi

Will 5.7 Adjust to 87 Octane

It’s no secret that higher octane gasoline burns cleaner and provides better performance in vehicles. But what about when you have to switch to a lower grade fuel? Will your car be able to adjust?

Here’s what you need to know about using lower octane gasoline in your car: First, it’s important to understand that the octane rating of gasoline refers to its ability to resist “knocking.” Knocking is a type of engine knocking noise that happens when the air/fuel mixture in the cylinders detonates prematurely.

This can cause damage to your engine over time.

So, when you use a lower octane fuel, your engine is more likely to experience knocking. However, this doesn’t mean that your car won’t be able to run on the lower fuel.

It just means that you may notice a decrease in performance and an increase in fuel consumption. If you regularly use a higher octane fuel and then have to switch to a lower one, your car will likely adjust without any issues. However, if you’re constantly switching back and forth between different grades of gasoline, it could cause confusion for your car’s computer system and lead to decreased performance overall.

Can I Run 91 Octane in My 5.7 Hemi

If you have a 5.7 Hemi, you can absolutely run 91 octane in it! In fact, 91 octane is the recommended fuel for this engine. It’s important to note, however, that if you do use 91 octane in your 5.7 Hemi, you may notice a slight decrease in performance.

This is because the higher octane rating of 91 means that there is less energy available in the fuel to be converted into power by the engine. However, the difference in performance will likely be negligible and not worth worrying about. So if you’re looking to save a few cents per gallon, go ahead and fill up with 91 octane next time!
