I'm not against lukoil, but I don't wanna go for an oil with least R&D plus amsoil is too costly to flush and i'm gonna change it after covering like 15000kms
I have used total quartz 9000 5w30. Many other pakwheelers are also using that. In my opinion its the best value for money and you can purchase authentic oil directly from parco at daraz. Here is the link &laz_token=a9c180d2d6f6e64a9d1efd9d1bceb161
I wasn't facing any performance issue on total or economy issue. It serves really well and a pretty great oil if you keep 5000kms drain intervals.
If you wanna keep your car under warranty and want best out of it while keeping warranty then I would suggest you to go for new Toyota TaglonX 5w30. It is semisynthetic, but you'll mantain warranty with it and engine will work fine on it.
