dimsim 2 Report post Posted October 4 My 130i is a Jap import and my understanding of Jap premium fuel is that it is 100 octane. While I’m happy with standard 95 my curiosity would mind trying a tank of 100. ive tried BP 98 before and tbh I didn’t really think there was any difference but I’d be happy if it went further on a tank for sure Quote Share this post Link to post Share on other sites
