the product is good value for money, and the manufacturer has been producing oils and additives for many years.so there is a good track record of quality. the quantity measurements (100ml/45 litres) is quite clear but trying to work out how much to use say for 361/2 litres would fry my brain and if you get the right answer you still got to measure it out.. so i think it would be easier to say something like "1 cap full / gallon (4.5 litres ) would solve a lot of brain ache.
