Engine oil Shell or AMSOIL

I am using shell advance ultra 10w-40 and hindi pa ako nagkaproblem dito sa oil na ito.

Im using amsoil. Change oil interval every 5k. Pag gipit, 6k kms.

I've been using Amsoil for mine since bought new

Amsoil OE for gasoline engines. Amsoil Turbo Truck for diesels. They are reasonably priced naman for their specs. They have the latest API rating din.

Motul H-Tech 100 or Shell Helix Ultra

ito gamit ko sa nmax V1 ko for 4 years, sobrang smooth ng makina, at sa sniper 150 ko naman ng 2 years, wala din ako naging problem sa makina, at sa nmax V2.1 ko ng 4 years wala din ako naging problem. Ito din gamit ko sa ADV 160 ko ngayon sobrang swabe sa makina, tahimik na tahimik. Mahal nga lang talaga 500+ pesos ang price nito pero sulit.

Amsoil Signature Series

Amsoil. Iba takbo.

Yo usaba Elaion en la Ecosport 2008 y es carisimo para lo que es. Ahora uso el Helix de Shell sin ningun problema

I've used amsoil 5w40 European formula ir worked great for when it was a street car, switched to royal purple 5w-40 due to a recommendation and immediately regretted it, tons of blow by I didn't have before. Dumped the royal purple CRAP as soon as possible, just a few miles on it.
