Lubricants for RV Chassis

Introduction

A motorhome chassis is made up of quite a few moving parts. Engines and transmissions that propel these large vehicles require lubrication to keep all of these moving parts operating in harmony. Chassis components also require lubrication. If you put the wrong lubricant in or fail to keep adequate lubrication levels or service intervals up and you'll have some expensive repair bills looming in your future. In this section I'll try to detail some of the basics behind the various lubricants. Most lubes are designated with a series of API or MIL category numbers. Choosing the proper lubricant consists of reading the owner's manual for your specific RV in order to determine which API service level you need to meet, then matching the lubricant's viscosity to the specs that relate to your operating environment. Note that this tutorial only serves to enlighten you as to some of the differences between the various lubricants. It does not replace your owner's manual, which will be the ultimate guideline to the service schedule that pertains to your RV. I've broken each section down by lubricant class so that you can easily access any specific area of interest that you may have.
