There's no quality 10W-40 around. I wouldn't put it even in my lawnmower.
A nice cosworth engine needs a quality full synth Mobil 1 oil. The best choice is 0W-40 or 5W-50. Or a good 10W-60 to silence the conscience.
what total rubbish lol and how on earth is a 0w 40 better than a 10w 40 lol the 40 is the same and the 0 is far to thin a 40 is a little thin but if you have a fresh engine its fine and will not leak i have no leaks and have 2 bar of oil pressure at 850 rpm ford say it should have 1.8 bar! plus mobile one has been proved as being shit lol but people read to far into whats good and what isent in a road car any good quality oil is fine as your not going to get it hot enough for it to brake down! i use fully synth shell 10w 40 as its on tap at work so free but really i should use a 10w50
