I've been hesitating between Liqui Moly 5W40 Synthoil Premium and Valvoline 5W40 Synthec. I have a Genesis Coupe 2.0T and after 3000Km on Pennzoil Platinum Pureplus the oil is already dark black. I did a flush and everything. I push my car hard so carbon deposits should be minimal not to mention the fact I also only buy Shell V-Power 91 octane fuel with all it's additives.
Many of my friends swear by Liqui Moly and they tell me it's the only oil that makes a big difference. They say it's too bad people don't know more about this oil. On the other hand there's the internet who says Valvoline Synthec is the best oil bla bla bla. Mobil 1... Bad experience with that oil in the family. Because my car as a turbo and an insane engine compression I needed an opinion on which oil is best for my Korean car. I love the car and I will keep it as long as I can.
Ps: I bough Liqui Moly MOs2 additive the 2009 version. The Cera Tec versio. Is not available to me where I live. Many people say it does wonders so I'll try to pour 2/3 of the bottle (which treats 7L) for my 5.3L oil capacity engine.
