I use synthetic oil in all my small engines, but it's not necessary.
Check your oil before each use and drain the gas out and run the carb dry of gasoline before any long term storage.

If wand is on and trigger is off, the pump has self destructed or part of it may have come loose and the water is leaking out.

There should be a pressure regulator somewhere in the pump, check your owners manual or go on mfg. Site and see if you can find your model.

Straight 30 wt oil. Be very careful when you fill it because if you over fill it, it will seize and if you under fill it wont get proper lube. The amount is about 2.5 oz.
