Engine oil Shell or IDEMITSU

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

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.

Idemitsu 05-W30 from Unioil kasi I cant find Castrol for my Mazda

Still using the casa oil which is Shell Helix Ultra 0W-20

Last change oil ko sa Shell, inabot ng 3200php including oil filter then Shell Helix SUV fully synthetic 5W-30 ang oil na ginamit.

Shell is good too but the toyota oils arent a wrong answer

Shell rotella t6 15w40 in my 86 Concours. Because it's full syn, readily available at the farm stores, and ol' Connie likes it.

Everyone has their preferences, at the end of the day it doesn't really matter, just change it regularly. I've used Mobil1, Pennzoil, LiquiMoly, Royal Purple, Rotella and probably a couple others I'm forgetting. No noticeable difference between any of them.

Stay away from rotella conventional. I’ve heard and now as well personally have had a turbo grenade due to their oil quality, that’s the conventional anyways.
