ZIC A ba gamit mo? AFAIK, ZIC is semi synthetic so you are right with the 5k OCI on your vehicles.

About the Toyota engine sludge, are the 1NZ-FE in the Vios and 1TR-FE in the Innova affected? Locally, I have read about sludge issues with local Altis with 3ZZFE engines. In the US, Camry had sludge problems.
