Pardon my ignorance, but why does a fuel additive need lubrication properties? Is it just for upper cylinder lubrication? I guess I figure it's more important for the oil to do that part of the job, and for a fuel additive to clean the fuel system and injectors/carb.
if it is related to upper cylinder lubrication could someone explain that a little to me, and explain why the right oil can't sufficiently fill this role?
There's several reasons, but let me just put this one on the table..
Here is what a basic injector looks like inside, give or take a valve or two.
Now, mind you two things, what does gas do to oil? Cleans it off? So, when you have a mechanical device such as the injector, there's several concerns, one, water or corrosion/rust.. Two, the piston and valves need some sort of lubrication, and three, the tip needs to stay clean and seals need to stay lubed.
Natural lubrication if fuel is from sulfur but the down side is carbon build up from the burning of sulfur. So, in some additives, they will clean, but what you need to ensure that you keep these parts lubricated and maintain a good Resistance to rust and corrosion so all these parts maintain optimal working condition.
There is horror stories from some of the local ford dealerships where someone puts in a fuel additive,(powerstrokes) and this messes up the injectors, mainly from seal damage. Reason is the lubrication is broke down, seal gets damaged and injectors start to fail. Lubrication is very important to a proper fuel system where motor oil cannot go to as that is not a primary side of the motor. Thats just a glimpse of why a fuel additive should have some type of lubrication qualities among other things.
