In the automotive industry, GC IB is C letter grease. Automotive experts suggest this grease when the bearing runs for a long-time. The grease helps your car wheel become rust-free, reduces extreme temperature, and provides faster performance.

What Is GC IB Grease?

GC IB is a top-rated grease and is mostly known as C letter grease in the automotive industry. The grease is recommended for U-joint, tie-rods-end, heavy-load valve, and so on.

GC is not only ready to reduce high-pressure and extreme temperature but also reduces stuck noise and provides stain-free performance. However, the temperature range of this grease is -40 degrees F to 320 degrees F; that’s enough for taking high temperatures.

Before using GC IB in your vehicles, you should find the GC IB grease specification to hassle-free use it.


  • It is ready to provide a wide temperature range (-40 degrees F to 320 degrees F)
  • Capable of taking enough load and extreme pressure
  • It is a C letter multiple greases for using multiple materials and valve
  • Provides long-time smooth running performance

What Is NLGI 2 Grease?

This is multiple grease which are also included in the C letter. But, you will find some differences from GC IB. First of all, NLGI 2 is designed for industrial applications and harsh chemicals. Chemical users choose this grease to reduce high temperatures.

Though the grease is manufactured for harsh chemicals and industrial appliances, it is also useable for high-temperature valves and vehicle bearings. Note that grease is not acceptable in marine vehicle bearings.

The lubricant of NLGI 2 and other ingredients can take a maximum of 400 degrees F temperature and a minimum of -40 degrees F temperature.


Though these greases are top-rated and the best in the automotive industry, you will find some differences. I made a chart for you so that you can easily make the difference between these two greases.
