Is it ok to have changing oil viscosities?

[sabaw]

250x4 or 2000 pesos per year isnt thst bad.

all oils work as i said. they dont magically make the engine last a lifetime. other components will fail first. tensioners bearings batteries. starters. coilpacks.

Alright so if you had the choice, which one?

Amsoil OE 5w-30 5ltrs = 2125
Motorcraft FS 5w-30 5L = 1900
Mobil 1 5w-30 5L = 3000

Again, thank you again for all the input
