Motor – SOS ! Corolla Verso – petrol engine !

Hello guys, today I accidentally pulled the oil measuring rod when refilling the windscreen wiper to see if there is still enough oil in it… ….on the oil measuring rod there was only bit of “burned/dried?” oil…. several attempts showed me that the rod no longer indicates anything!! Conclusion too little oil in the engine…. On the engine hangs the famous shield… NEXT OIL EXCHANGE LATEST AT 45,000km…..original Toyota engine oil… ….and then what shrill what looks like 10/40 L L ???? Can that be? What does this term mean? Which oil is normally pure for the 1.8 petrol tank?? Well, the 60,000 inspection is already due…have already 64,000km on the clock….. Well next time I check the oil more. Couldn’t guess that the so much oil eats. Who can help you quickly….then I can quickly blow in to the hardware store and dump an emergency solution….before everything is too late. thx
