1. Only buy or fill up your car or truck in the early morning when the ground temperature is still cold......TRUE
2. When you’re filling up do not squeeze the trigger of the nozzle to a fast mode.........TRUE, but hardly a big difference.
3. One of the most important tips is to fill up when your gas tank is HALF FULL.......TRUE, but again, hardly a big difference.
4. If there is a gasoline truck pumping into the storage tanks when you stop to buy gas, DO NOT fill up.......TRUE........especially for fuel injector engines and especially DIESEL. But I’d be more worried about an explosion from a passing cigarette...........
I have a feeling all of these cases would equate to 1/100th of a percent difference.
An explosion from a passing cigarette is about as likely as your Glock leaping from its holster and blowing a hole in your head.
