Well, I tried it and I do not like it. Some valve oils will give your fast valves but the consistency of the oil sometimes disperses the oil so fast that the oil does not give you long lasting fast valves. That is what this oil does. I had to re-oil my valves every day in order to keep them working smoothly. So, I’m back again to my Al Cas valve oil which keeps the valves working smoothly for a much longer period.
