bravo 35 Report post Posted February 2, 2016 Hi all I'm considering buying an e91 and there are a lot of imports with the N53 engine (325i and 330i). Wikipedia says the N53 was never sold in the Australia market due to the high sulphur content of the fuel. Our fuel is also high in sulphur. Does anyone know of any problems from imports running N53 engines on NZ fuel? Cheers Quote Share this post Link to post Share on other sites
