Hi guys,

I have recently had my entire engine overhauled...so new everything from pistons to valves, timing chain etc etc...so complete top and bottom end...

The comapny that rebuilt it put 15 w 40 oil in it. I have to change this after 500 miles...so my question is should i stick to 15 w 40? Im thinking of using the exact same oil and brand forever. was thinking about Castrol GTX magnatec 15w 40.

Are there any other things that i need to know about running it in?

many thanks!
