Engine Oil

Hi Guys.

I'm looking to change the oil on my n14. It's done around 340k and was thinking of buying synthetic 10w-40 for it as it's an older engine but the engine runs nicely with no excessive smoke or anything. Help would be appreciated. Corey

I use castrol magnatec 10/40 does the job. Just make sure the oil you get ISNT GF-5 rated.
