Hi again Jarek, You can use straight engine oil but even a 5/xx multigrade is a bit thick and tends to dampen the piston too much. We mix 50/50 light machine oil and engine oil. If it keeps disappearing it means that the rubber O-ring which seals the needle inside the piston is perished. regards Rob
