Just wondering if they work.
I've only used the transmission treatment. As with all products like that, they are mainly designed to get a little more life out of a feeble old vehicle. Because of that there isn't a whole lot you can expect but it was a definite improvement to my 20 year old Volvo transmission. I don't recommend any additives for a vehicle in its prime. Using the right fluids in the first place (including top tier gasoline) is good enough.
they are excellent products. I use the oil stabilizer every oil change. On my car I always had a valve clicking and nothing would stop it. the first time I used the Lucas the clicking stopped afer the first 2 minutes and has never started back and that has been 4 years ago. Id use the gas treatment every third tank of gas.
Go to their site and carefully read exactly what these additives do and don't do. For instance: If you have a hydraulic valve lifter that's sticking, does either of their oil treatments clean the lifter or cover-up the noise? They advertise you won't have dry starts when you use engine oil stabilizer. What they don't tell you is the oil pump slows down its ability to force a large volume of lubricant to frictional surfaces during start-up. Cold starts is where 80% of all engine wear occurs. Why would anybody want to slow down the oil pump pressure to internal engine parts during cold starts. Full synthetic motor oil flows faster when the temperature is cold. 3M Total Fuel System Cleaner is a click above Chevron Techron.
All you would have to do is bleach the sharpie part with a cleaning tootbrush or whatever you have really. then wash it.
