I have a Suzuki Liana 2002 with LPG system (lovato). I use this lubricant (which I was told to by the guy who installed my system)

this is what I use

Unfortunately it costs a lot. I saw there was another one I wanted to use if I can use the other one which is cheaper and it will do the same job perhaps?

the other one I wish to know if I can use

Is there any 5 Liter refill I can use to refill my original one?
