do you know that a Semi Synthethic 10W-40 Engine Oil from a reputable oil producing company costs a bomb in Malaysia? Petronas Syntium 800 costs like Rm1xx... Esso also hundred plus.

But in Thailand I bought a Semi Synthethic 10W-40 Engine oil with latest Api ratings is only 599 Bahts. From PTT. not some unknown brand.

So why cant Tesco Engine Oil be used? It has the necessary Api ratings etc and it is made in Singapore. Still want to pay silly money for unreasonably priced Engine Oils from the local oil companies?
