What is the difference??

 

[nvrenuf]

You'll need to read each pack but the different colors can designate the intended application (fuel resistant, O2 safe, etc.).

I use ultra grey for everythin..

Ultra black = Hi temp..
Ultra grey = Sensor Safe..
Ultra red = Hi temp heavy duty
Ultra blue = low odor, sensor safe, noncorrosive.

I go with ultra black also. It resist all fuel and seals sending units on my diesel tractors and gas power trucks as recommended on the package.
