Best Spark Plugs for Fuel Economy?
Hey what's up guys, so I've been experimenting to see what could be the best spark plugs for my 2015 Mirage to get the best fuel economy. Now I do live out in the country and with what I have been getting depends on the driving (more likely nice and easy), I average around 50mpg. That with Denso Iridium Power Spark Plugs. Now I got to looking around and seen that NGK 5018 Platinum Spark Plug could do better. Not the case. Same driving conditions and nothing different my car dropped to 45mpg. So now I'm wondering, if maybe there is something better or should I just put the Denso Iridium Power Spark Plugs back in? But still, if appreciate any thoughts or ideas. Thank you!
