What oil would I be best served to use for my cat pump on my pressure washer?

Thank you in advance for the assistance!
 
Use Cat Pump Oil......its 30wt non-detg.....its blue in color.....I buy my at Home Depot......change every 60 to 75 hours.
 
my local home depot doesn't carry it but I'll look on their website or online. Thanks for the quick response!
 
I've been running Honda Powered pressure washers with Cat pumps for well over 30 years with 30 grade non-detergent oil in the pumps. I have a machine here close to 30 years old that just started leaking a bit of water in the pump causing it to mix with the oil. Not bad considering the age. I also acquired one that needs a pump, it sat out over several winters and the water froze in the pump and ruined it, but that's a another story.
 
Cat pump oil in Cat pumps...duh.

My Honda powered pressure washer calls for diesel grade 15-40 for the pump.
It has a sticker on the pump .
 
I have a Hotsy Shark. Hawk pump. Use non-detergent 30wt compressor oil from Oriellys with a little Lucas stabilizer, calls for ND 40wt. Had it about 20 years and has been fantastic. 11hp B&S I/C leaks a little oil but never gives trouble so I just leave it be.
