Well it was tuned for the big turbo, you had to put in a smaller one, so it chokes cause too rich. Just like its owner, too rich. hahahaha.vr2turbo has answered for me.
No. So buyer must practice caveat emptor. That's why big brands, Mobil 1, Castrol or even Shell are safe choices. It may not be the best money can buy (Shell isn't that great) but it won't be bad.So many funny brands this days even at Lazada. RM60 for fully syn. Are there any regulatory body which regulate these ?
Those local brands could be using recycled oil, who knows man. If you read car manuals it will need minimum API or ACEA certification. "Meets API/ACEA" standard and API/ACEA certificate is different.
You could be a pilot who meets the flying license standard, but you don't have an actual flying license.
