QS 10w40?? Whaaaaa!!! It\s too cold for such thick oil man! That's used for oil burnin V8's!! I am am a Auto Technician for 10years and unless I am retarded that 10w40 is NG for your motor unless you are burning oil like a 2stroke lawn mower.
Let me tell you i have a d16y8 VTEC and I deman the best oil for my car because I want my motor to last, run at uit's best, and provide optimum gas milage. The best oil would be Mobil-1 Synthetic 5w30 espcially in winter. Can use in summer but if you got over 150,000km and you will hammer it the summer go 10w30 no thicker than that, otherwise stick to 5w30
This oil is at a decent price, compared toreline and royal purple, buy it in a bulk box at costco (priceclub) and you will save. Also oil filters stick to no cheaper than regular Fram, when you pay less you get less paper filtration media
