15W50 "motorsport" oil

[mark123]

I've seen this stuff in Halfords. I'm talking the Mobil 1 stuff rather than their own take on it. They brand it "motorsport" or something similar.

Any thoughts on this stuff versus the equivalent 0W40 or 5W40?

Is it just not necessary or is it even a bad idea?

Don't use it on CLios its to thick when cold for the engines and not right realy unless the engine gets very hot

0 or 5 or 10 40 is what you want

not necessary or probably worthy of the label
