DENISON, Texas (KTEN) — We've all heard about tips and tricks for saving on gas and as prices continue to rise we thought it was time to see which hold up and which experts question.

Things like which day of the week or time of the day you fill up, or even how quickly you fill up might not make a difference, but there are some time-proven ways to squeeze more miles out of every gallon, like accelerating more gently.

Experts also warn that while you might not have enough cash to keep the tank full, you'll want to keep it at least a quarter-tank full.

"It's important not to run low on fuel," said AAA spokesperson Daniel Armbruster. "If you're consistently running on E, you can actually damage your fuel pump and other parts in your fuel system, and that can be rather costly."

While gas prices go up and down every year, Austin College professor Dr. Peter Schulze, director of the Center for Environmental Studies, believes that sanctions on Russian gas are partially to blame.

"If other things in the economy happen that effect supply and demand, for example, various countries trying not to buy Russian oil causes prices to rise," he said.

Regardless of the reasons, all motorists are doing whatever they can to save a buck.

"I'd rather keep it on full," said driver Clinton Harris, "Cause I never know when it's going to go up or when it's going to come down."

Jose Rodriguez said he has to fill his tank every day because he travels.

"Actually, I'm about to fill up right now," he said. "Prices go from $4 to what, $4.80?  ... and what's the price right now? I don't even... well actually, I don't even look at the price. I just fill up.  That's all."

Always be sure to double-check any gas-saving tips or tricks you read with an expert; some unproven tips may even end up costing you more in the long run.
