Insider Spills the Ultimate Gas-Saving Secret Using This Little-Known Credit Card Trick!

Credit cards are a handy financial tool for a number of reasons, but I’ve always been interested in them for the rewards they provide. Whether it’s airline miles, hotel points or cash back, I’m always looking for the right card that will earn me the most value.

As someone who spends a significant amount on gasoline each month, I recently found myself enticed by the Blue Cash Preferred credit card offered by American Express. The card’s promise of offering 3% cash back on U.S. gas station purchases was too good to pass up, especially since I tend to spend around $200 on gas every month.

Based on these expenses, I assumed that I would only be able to earn around $6 in cash back rewards per month. However, I later discovered that this card has a few other tricks up its sleeve that really helped maximize my rewards earnings. In this article, we will go over how I have used the American Express Blue Cash Preferred card to make the most of my cash back rewards on gasoline purchases.

One thing that drew me to this card was the lack of rotating categories that I have seen on other cash back credit cards. Instead, the cash back earning rates for this card are based on everyday purchases that I already make. This means that, unlike other cards, I don’t need to enroll in specific programs or keep track of which categories are eligible for cash back rewards each quarter.

Another reason why I love this card is because it does not have a spending limit on the 3% cash back on U.S. gas station purchases. For those who need to fill up multiple cars or are small business owners who use their card for gas purchases, this is particularly beneficial.

Outside of its excellent gas rewards, the American Express Blue Cash Preferred card offers up to 6% cash back on select U.S. streaming subscriptions and 6% cash back on groceries at U.S. supermarkets (on up to $6,000 in combined spending per year). These additional perks further increase the overall value of this card and make it an excellent addition to your wallet.
