garyq,
How much is the Petron All Terrain?
The last time i asked, Petron all terrain 5w30 was selling at P235/L.

Anong VIC part No na gamit ng 4JX1?
I can use Vic part no C524 for primary filter which is about P175. Just list your orig isuzu oil filter part no and i'll check what Vic part no is compatible.

Where is Walco, Banawe? Do they carry isuzu parts at prices below that of casa?
