If he's burning a bit of oil he might want to go with a 10w40, but he's probably best to stick with one of the high mileage 10w30s, which are very thick 30wts.
Why not just 20W-50?
Why is he being told this? Leaks? Wear consumption?
Either way this is always a downhill proposition -to just use a "thicker" oil, if the car is mechanically ill. Eventually fix or throw away will happen, and going to a thicker oil sometimes will make wear worse (straigt 40W on a cold morning??)
We need more symptoms or a true diagnosis.
