I read there were four tips to increase gas mileage.


!. Look online the the cheapest gas in your octane range in your area.
2. Fi ll up first thing in the morning due to lower temperature in the tank
3. Do not fill up when the tanker truck is putting gas in the tank.
4. also fill up when the tank is half full

I read this in an article about saving up to 15 % on gas cost by doing this. The last three have to do with the gaseous (fumes) content in the flowing gallon. I don't know if any of this is true. What do you think?

I lost the website for gas pricing so if anyone has seen this let me know.
