Using 10w60 instead of 5w30?

Hey guys,

My mechanic has mentioned to use 10w60 since its been burning oil consistently. Ive been using 10w60 for about 2-3 yrs now, and now seem to be getting problems.

Oil leaking badly in the spark plugs, coils, etc. should I switch back to 5w30? Is this potentially the reason why it has been leaking??

Anyone have experience with this??

Thanks!
