I do not know if this is good or not but I have done it when I had nothing else and that is using a mix of drain oil and gasoline. I did not measure it but if I had to guess it would be about 15% oil the rest gas. It does last a long time and it cant be any worse that some of the other stuff they sell in the store to do it. I am sure the other things folks have talked about work great and I would most generally do the same. I just said this because I have use it in a pinch and I would bet that some of you that are also making a living with horse, mules, ox,…. might get in a pinch once in a while . Taylor Johnson
