Q. What's the correct way to grease a fifth wheel?

March 31, 2014

A. Good question and an area that is most often neglected or done incorrectly. Many truck 5th wheels are re-lubricated by simply taking the grease dispensing unit and dispensing a ribbon of grease around the 5th wheel plate and often neglecting the 5th wheel jaws which engages the trailer pinion entirely.

Q. How do I choose the right grease?

September 18, 2013

A. Greases vary widely in their performance capability in respect to the basic performance factors. Greases for heavy equipment can be designed to pump very easily in cold weather while lasting up to three or four times longer in severe service. The key is to ask the right questions regarding grease design and performance capability matched to the operating conditions.

Q. There used to be a popular idea that the brand of oil used in an engine should not be changed. Is there any truth at all to this?

How about if you change from regular to synthetic? Can a person just experiment with oils to see which one works best? How about mixing them? By that I mean using an odd brand in a pinch when you can't find the one that's in your crankcase?

July 31, 2013

A. It’s perfectly fine to change brands of oil – the engine doesn’t care.
