If you really want to try, its your money.
To save fuel, use API rated energy conserving oils. This will really save you gas. Brands that are easy to find in the Philippines are Caltex Havoline Energy and Royal Purple. I have seen a few others at True Value but dont remember the brand names. Typical viscosity for this type of oils are 5w30 and 10w30.
