So mga sir : a fully synth oil with a lower API rating is still much better than a mineral oil with a higher API rating?
it's the other way around, a mineral-based engine oil with higher API rating is better than a fully synthetic engine oil with lower API rating.

among the choices pipiliin ko yung sa Sea Oil...personally, i would stick to the engine oils of the big 3 at sa mobil...subok na eh...gives you peace of mind...

scanner, Delo Gold Multigrade is API-CH4, Delo 400 yung API-CI4(di pa available locally)
