Is same grade of gas for my mazda car ok for Karcher 2400 pst? Also, oil to use in late spring?

Yes, the same grade of gas used in a Mazda car—unleaded gasoline—is suitable for the Kärcher G 2400 HH. For oil in late spring, refer to the engine’s operating manual for the appropriate seasonal oil grade.

I have a Karcher G 2400 HH. The gas engine runs great if the trigger on the wand is not pulled. When the trigger is pulled it spits and sputters then the gas engine shuts off. Also the detergent hose blows water out of it. When the trigger on the wand is not engaged water spits and sputters out of the detergent hose. When the trigger is pulled the water coming out of the detergent line greatly increases but the water pressure on the wand is greatly reduced. Thanks-
