The YSR uses oil injection. It holds about 24 ounces and normally does about 17 Ymiles per ounce. The warning light comes on at about 17 ounces or close to 290 Ymiles. I carry extra oil in 18 oz shampoo bottles. With 396 Ymiles behind me, at Los Cruces, I get another 1.95 gallons of gas.
First thought is the plug.
The plug looks pretty awful so I put in a new one. Things never get back to normal, the ride is no longer much fun. I've got visions of quitting. But with eight hours already invested I decide to press on. I watch a beautiful sunset in my mirror as I head southeast past El Paso.
