Hi,
A mate is just at the minimum/just below with his oil. The car tasts 5w30 and that is what is in it, now the question is. What would be better to do to tide him over, Castrol GTX Magnetec 10w40 or a cheap 5w30? Bearing in mind he will only be topping up the oil.
It needs to last 2.5 months.

Noticed a litre of GTX is only £9.80 at Halfords so a motor factor should be cheaper.
Any ideas/advice? Would only be a little bit but still...
