ppine Posted October 21, 2019 Share Posted October 21, 2019 So far I am getting around 21 mpg, mostly highway driving. Some people report up to 29 on their 430s. I am running the car more in regular Drive, and have a K&N air filter. What mods or habits are good for mileage on these cars? Hard to believe anyone really gets 29 mpg.

Paul Cook Posted October 21, 2019 Share Posted October 21, 2019 That's about what I get too in SoCal. I between 20 and 21 MPG depending on what I am doing. And that is mostly freeway miles. I don't know who these people are getting 26 +, but I would like to talk to them. Paul Quote Link to comment Share on other sites More sharing options...
ppine Posted October 22, 2019 Author Share Posted October 22, 2019 All sources suggest 33 psi tire pressure on 430s with standard size tires. Maybesome people pump them up. Michelins have a max pressure of 51 psi. Quote Link to comment Share on other sites More sharing options...
SCuiter Posted October 31, 2019 Share Posted October 31, 2019 I've been getting 18-20 mpg around town, having fun, in power and normal mode, not much highway at all. I haven't tracked mpg for any all-highway trips, but the the closest thing to that was 19.8 so I expect about 20-21. Quote Link to comment Share on other sites More sharing options...
ppine Posted July 8, 2020 Author Share Posted July 8, 2020 Now I am getting about 23 mpg, which goes up a little with all highway driving. It is quite acceptable for a performance car. Quote Link to comment Share on other sites More sharing options...
