mrnobady Posted June 19, 2023 Share Posted June 19, 2023 During the first fill-up, I saw a sticker inside the filler flap that said 'USE PREMIUM UNLEADED ONLY' or something to that effect. Is it okay to use ordinary 95RON in the engine, or should I use the cheap juice? I'm willing to go with premium 98RON if it means improved performance and efficiency. My car arrived with a Bose music system and a 6-CD changer, but no AUX-in port (which is normally located in the armrest pocket). I'm thinking about obtaining the XCarLink Kit to add iPod/iPhone connection, but I wanted to see if anybody had any issues with installation or general usage beforehand. Thank you, and please accept my apologies if these questions need to be reposted someplace more suitable! Quote Link to comment Share on other sites More sharing options...
blueWING007 Posted June 19, 2023 Share Posted June 19, 2023 You can find a lot more helpful information elsewhere. This discussion board has been active for nearly 5 years, during which time many topics have been discussed. Any question somebody may have has probably been addressed before.

bentleygt77 Posted June 19, 2023 Share Posted June 19, 2023 welcome to the clan! According to the manual, various Mazdas are calibrated differently for different regions, such as the United Kingdom and the United States. I've been using premium unleaded from the local petrol station, but I'm told it's 95RON and it seems to function fine. MPG is terrible in the city, but it is the same for all vehicles.

Rudy7831 Posted June 19, 2023 Share Posted June 19, 2023 Good day and welcome. If you get into difficulty, we will try to help as much as possible. For practical reasons, I'm still using Windows 98 on my. In my opinion, using 95ron will provide you with safety. I'm certain you'll discover some helpful information on the X Car Link by using the site's search function. Quote Link to comment Share on other sites More sharing options...
mrnobady Posted June 19, 2023 Author Share Posted June 19, 2023 OK, thanks; I'll reread the manual regarding the fuel query and conduct a search for xcarlink-related topics. Still keeping my fingers crossed that the legendary Mazda reliability record will translate into few (if any) maintenance and repair questions.

DenishP4 Posted June 19, 2023 Share Posted June 19, 2023 There's a lot to know about this, and if it's not an MPS, there's no need to run it on super. The knock sensor and ECU are set up to run 98ron like an mps. Quote Link to comment Share on other sites More sharing options...

The knock sensor and ECU are set up to run 98ron like an mps. Look at the crank's bottom pulley to see that this is not the case. By adjusting this sensor, you may enjoy super unleaded's advantages. The only thing I've done to mine is make the power curve a little bit smoother and increase the sport's speed from 6k to 7k. There has been no change in MPG. Mazda uses this method to adapt to the different fuel standards in each nation. While those on the American site seem to cluster towards the top, I discovered my profile closer to the middle.
