Hello skhell
That is an interesting project you are working on. Is the lubricant you are injecting into the engine air intake an item that is normally found in the gasoline the engine normally would burns but that the LPG gas does not have? I was not aware that this was required when using LPG to power a car. I assume the lubricant is required to extend the valve seat and valve live since the rest of the valve is lubricated by the normal engine oil. In the old days of leaded gasoline this job was done by lead in the gasoline. I have wondered what was used when the lead was removed, but have assumed that improvements in valves/seats made a lubricant not necessary. If you have some details on this I would like the read about it. Thanks.
Hi!
It is just as you said.
Gasoline has some additives that LPG doesn't have, which may cause the valve seats to recess. Also, the burning temperature of LPG is a bit higher than gasoline. The conjunction of this tow factors, may damage the valve seats of some engines that have "soft valves". There is a list with some of the engines that need that protection when running on LPG(

There is a kit called Flashlube(
http://www.flashlube-europe.com/en/p...saver-kit.html ) that is very used worlwide but have some flaws. The one I am using is similar to that one, but has some little differences. The main difference is that when the additive gets to the air intake is already vaporised in air, and with the flashlube, it only gets vaporised when it gets on the air intake, which can make the oil not be equally distributed.
Also the kit I have increases the flow of additive with the engine charge, while in Flashlube is always constant....
What I want is to fine tune the amount of fluid that gets in the engine, because relying in the vacuum of the air intake to control the flow of additive is not very good and not very accurate, because the are many turbulence, making the flow of additive to change allot...
If you need any info let me know
