Valena-SVC is very interesting, impressive and has an excellent concept.  It really helps and creates a big impact mainly to our car and oil industry.  I was impressed by it benefits offer to the engine component durability, fuel efficiency and most especiallly environmental friendly.  Hopefully this kind of product can be useful to the other regions.  My question is, is this product (additives) applicabale to the countries with different climate conditions? Will this additives applicable both to gasoline and diesel engines?
