CNN - We're all looking for ways to stretch our gas money but there are some big myths floating out there that are a big waste of your time and money to do.
One of the most common myths, according to the EPA -- is that the smaller the car, the better.
This is not so. Experts say due to advanced technologies you don't have to drive a tiny car now to get good fuel economy.
For the 2014 model year, half of the most fuel efficient vehicles are midsize or large cars.
Another myth -- that premium expensive gas helps you get better mileage. Well, not quite.
Cars that are specifically designed for this premium gas may see a benefit but everyone else won't get a gas mileage boost from this replacement.
And, then there's the myth that manual transmissions get better mileage than automatics.
Experts say changes to automatic transmissions over the years have improved their efficiency, so now there's really no difference between the two.
And lastly the myth that you should let your car idle rather than turn your car off and on because restarting your car uses more gas than idling -- say you're waiting in the parking lot for your kids, for example and leave your car running for several minutes.
This is also not true. Idling can use a quarter to a half gallon per hour while sitting for extended periods. The experts recommend that you turn off your car when you're not moving -- unless, of course, you're sitting in traffic
These are all good tips to know -- especially ahead of any long road trips you may have planned for this summer.
