I thought got some special skill to detect fake EO. Rupa2nya, just the same method where most people use. Compare the bottles with ori.
Thing is, I need to compare Toyota, Honda, Proton, Perodua, I have to standby all the ori bottles to compare. First, I have to spend money to buy the ORI ORI oil and then compare to some shops claiming to be ori. Been there done that. Not 100% effective. Waste of time and money too.
Also for the viscosity tester, I don't think there are anything cheaper than few k to build a tester. Most of the proper testers are lab equipment that if your pomen know how to use, he no need to open workshop. Open science lab make more money. Please share if there are cheaper method to test oil viscosity. Don't tell me go freeze the fake oil and genuine oil then compare the flow rate. And no, you cannot tell viscosity by looking at the lube or rubbing with your finger.
You also mentioned, knowing only after putting the oil into the engine. Isn't that too late already? Plus, fake oil and genuine oil sometimes are hard to tell even by driving the car. I am very sure if I give you do a blind test of fake vs genuine oil, you won't be able to tell them apart 10 out of 10. Maybe 5 out of 10 which is still not accurate.
Sigh..the way you say I thought it's some new kung fu for me to learn to tell apart engine oils. If got, please share. I am always eager to learn new things.
Cannot open ma, all bottle is sealed with the alumium foil.
Unless u can take out the oil then show u how to test lo and smell lo.
Lesson to be learned, don't be cheapskate and want something the price lower beyond the original .
