Just wondering what the right gauge to use under the hood with the temps. Liquid filled or non filled? what is everyone else using and is there any benefits from either? Thanks
 
Filled definetly it dampends the vibrations from the motor and gives more accurate readings.I used a non-filled one on one of my old cars and it kept rattling the cover screws out of it.

Thanks a lot for the quick responces Gents! Thats awesome because the one that I liked the best was liquid filled.
