Those companies who engage in true preventative maintenance enjoy better equipment availability which as you know means a LOT more profit. (Longer equipment life, less parts, labour, rental equipment costs, performance issues based on the contract ...) The loader you see has one of our filters on the engine and one for the hydraulics. Oil analysis will clearly show the performance of our by-pass filters. (1 micron filtration rate, and remove 100% of the water.) Call us, we have been in this for 25 years.
