CAT Pumps pressure washer pump oil is a special ISO 68 formula available in 21oz and 2.5 gallon sizes. CAT recommends you use their oil to get the most from your pump and not void any current warranties. Keeping the CAT pump on your pressure washer properly lubricated is crucial to maintaining peak performance and efficiency while maximizing the lifespan of the unit. Take note of the crankcase capacity listed in the manual for the model your using on your pressure washing unit, and be careful you're putting the correct amount in without overfilling. Recommended oil change frequency is once after the first fifty hours, and then every three months or 500 hours after that. Pro pressure washing companies can put hours on pumps very quickly, so it's a good idea to have plenty of oil on hand to take care of changes as soon as it's needed. We also offer drain kits and level indicators to make monitoring and changes easy!
Along with buying oil, CAT also offers helpful accessories to make monitoring and oil changes easier. Pick up a crankcase oil indicator to easily monitor the oil level in your pump. They mount to the rear cover drain port and offer a way to keep track of the level with a simple glance. Oil drain kits allow you to quickly get old oil out of the pump before adding new. Not only do drain kits make the process faster, it also makes the task cleaner by guiding the oil directly to a pan.
