Amex Blue Cash Preferred for Gas: Is 3% Worth the $95 Fee?

The Amex Blue Cash Preferred appears on many "best gas cards" lists. But at only 3% on gas with a $95 annual fee, it rarely makes sense as a gas-only card. Its real value comes from combining the 6% grocery rate with the 3% gas rate. Here is an honest assessment.

Gas Rewards in Context

On gas alone, the BCP rarely makes sense.

3% on gas with a $95 fee means you need $3,167/year ($264/month) in gas spend just to break even against a card earning 0%. Against a free 3% card like the Wells Fargo Autograph, you never break even on gas alone because the rates are identical but the BCP costs $95 more.

Against a free 5% card like the Citi Custom Cash, the math is even worse. At $200/month gas: Citi earns $120/year with no fee. BCP earns $72/year minus $95 fee = -$23/year net. You would literally lose money using the BCP for gas compared to a free alternative.

The Real Value: Groceries + Gas Combined

The BCP becomes worthwhile when you combine its 6% grocery rate (up to $6,000/year in grocery spending) with the 3% gas rate. Here are realistic family spending scenarios:

Groceries/mo	Gas/mo	Grocery rewards	Gas rewards	Total rewards	Net after $95 fee
$200	$150	$144	$54	$198	$103
$400	$200	$288	$72	$360	$265
$500	$200	$360	$72	$432	$337
$500	$300	$360	$108	$468	$373
$300	$100	$216	$36	$252	$157

Grocery rewards capped at $6,000/year in spending (6%), then drops to 1%. Gas rewards at 3% have no cap. All amounts are annual.

Who Should Get This Card for Gas

Good fit:

Families who spend $300+/month on groceries AND $150+/month on gas. The combined category value covers the $95 fee and then some. Especially good if you also use streaming services (6%) and public transit (3%).

Not a good fit:

Drivers whose primary goal is maximizing gas rewards. A free 5% card like the Citi Custom Cash or PenFed Platinum Rewards earns more on gas with no fee. The BCP is a grocery card that happens to earn 3% on gas, not a gas card.

BCP vs Dedicated 5% Gas Cards (Gas Only)

Card	At $200/mo gas	At $300/mo gas	At $500/mo gas
Amex BCP (3%, $95 fee)	-$23	$13	$85
Citi Custom Cash (5%, $0 fee)	$120	$180	$300
PenFed Platinum (4.25%, $0 fee)	$102	$153	$255

Gas-only net annual return. BCP net = gas rewards minus $95 fee. Free cards shown at full reward with $0 fee.

Frequently Asked Questions

Is the Amex Blue Cash Preferred worth it just for gas?+

No. At 3% on gas with a $95 annual fee, you need $3,167/year ($264/month) in gas spend just to break even on the fee compared to a card earning 0%. Against a free 3% gas card (like Wells Fargo Autograph), you never break even on gas alone. The BCP is only worth the fee when you factor in the 6% grocery rate and other bonus categories.

How does the Amex BCP compare to 5% gas cards?+

For gas-only rewards, the BCP loses. At $200/month gas: Citi Custom Cash earns $120/year (net $120, no fee) vs Amex BCP earning $72/year (net -$23, after $95 fee). The BCP catches up when you include groceries. At $500/month groceries + $200/month gas, the BCP earns $432/year total, netting $337 after the fee. A Citi Custom Cash can only earn 5% on one category.

Does the $6,000 grocery cap affect gas rewards?+

No. The $6,000 annual cap applies only to grocery spending at the 6% rate. Gas rewards at 3% have no published cap. These are separate categories with separate limits. After $6,000 in grocery spending, groceries drop to 1%, but gas continues earning 3% regardless.
