yes its true. many fake oil in the market. be very careful with the seller gjrforce in garage sale. i bought 2 times engine oil from him, both also my mech said is fake.. the second fake actually cost my whole engine. true story

the first time i had the problem, he said his stock was from singapore or something. i forgot the actual detail but it wasnt locally distributed if i remembered correctly. when i change the engine oil, it smells funny. at the same time my o2 sensor kong. so i thought maybe is my problem. the second time i bought for my V6 engine. after back from KL-Ipoh-Langkawi-KL trip, the engine burns. maddriver can confirm this. the engine oil stink like hell when we open the engine oil cover
but i was like doing 180 all the way in the trip, i wasnt sure whether is my engine kenot tahan (10 years car) or is the engine oil that fault.
i dont have actual data to support my fact so im not going to post there. but i'm saying here as a warning and to share my experience
