5k service

im just about to service my car and i wanna know what oil i should use i think ive ised 15w something cant remember but its a 90 model and has 120 000 on the clock?

 

10W40 OR 15W50 will both be fine

 

both are ok, 15 w 50 is probably better for those kays and a hot climate

 

Have a look at Nulon 15W-50 Street and Track, its a good fully synthetic oil.
