Fort Knox Federal Credit Union Visa Platinum Review – 5% Cash Back On Gas

This is another post in our weekly series, “Weird Wednesday” where we look at a slightly unusual or weird credit card every week, more posts in the series can be view here. We haven’t run this series the last couple of weeks due to time restrictions (and lack of ideas), so make sure you help us out by suggesting cards to have a look at.

Today’s card is the Visa Platinum card that is issued by Fort Knox Federal Credit Union and earns 5% cash back on all gas purchases.

Application Information

It’s possible to apply for this card without becoming a member of Fort Knox Credit Union, by using the non members link during the application process. Note if you do decide to join they will usually do a hard pull for membership and approval is not automatic.

They’ll also sometimes request additional information to approve you, for example last two tax returns, social security card, drivers license. I also believe that somebody actually looks over each application manually (especially if not already a member).

Common Reasons For Denial:

  • Too many recent inquiries
  • Not employed for long enough
  • Too much existing debt

Fort Knox are incredibly inquiry sensitive, it seems that if you have more than three inquiries in the past six months you’re almost guaranteed a denial. Even if you’re under this number then approval is by no means a sure thing.

What Credit Bureau Does Fort Knox Pull For The Visa Platinum?

Fort Knox will usually pull your TransUnion credit report, in some cases they’ll pull that in addition to your Equifax credit report. They’ll usually do this double pull when you have a number of new inquiries on your TransUnion report.

What Credit Limit Will I Receive?

You should be able to specify your preferred credit limit during the application process.

Rewards Program

This is a cash back card. Interestingly in the past you were able to pay off this credit card with another credit card, without any cash advance fees, they then made it so cash advance fees were charged before closing the loophole entirely.

Earning Rewards

The rewards program on this card is really quite simple, you earn at the following rates:

  • 5% cash back on all gas purchases
  • 1% cash back on all other purchases

In the past this card earned 1.25% cash back on all other purchases, but given that you can earn 2%+ cash back on all purchases this isn’t exactly an issue (this change happened in early 2013). They have offered 5% cash back on gas purchases since at least early 2010, so it doesn’t look like this deal is going away any time soon.

Sign Up Bonus

This card has never offered a sign up bonus that I am aware of. I’m also not aware of any targeted bonuses on this card, there is also no way to see if you have been pre-approved or not for this card.

Redeeming Your Rewards

There is no limit on the amount of cash back that you can earn. Cash back will not be shown at the time of purchase, but will appear on your monthly billing statement.

Our Verdict

It doesn’t really make sense to look at this card in isolation, especially when there are other cards that also earn 5% cash back on gas purchases:

  • Sam’s Club Mastercard earns 5% cash back on gas but has an annual limit of $6,000 in spending. Also has 3% cash back on travel and dining and you’re limited to total cash back of $5,000 per year. There is no annual fee, but it requires a Sam’s Club Membership.
  • Full list here

If your  gas spending is under $250 a month, I think the Sallie Mae card is your best option, if it’s under $6,000 annually then Sam’s Club might be your best option (if you already have a membership) because both of those cards are easier to get approved for and also have other cash back categories higher than 2% (which is the baseline you should be getting).

If you do have a lot of gas spend, this card might be worth getting. The problem is you’re probably going to need to not apply for cards for awhile so that you can actually get approved. There are also two other cards worth a mention, the Discover it & Chase Freedom, both of these cards earn 5% cash back in rotating categories (up to $1,500 per quarter) and usually have gas as a category at least once annually. A full list of the best credit cards for gas purchases can be found here.

We Recommend This Card For:

  • People with large gas expenses

We Don’t Recommend This Card For:

  • People with gas spend under $250 monthly or $6,000 annually
  • People with multiple new inquiries on their credit report

” There is no annual fee, but it requires a Sam’s Club Mastercard ”
You mean Sam’s Club Membership?.


Is this 5% for gas at the pump like Penfed? Or is truly 5% on any expenses at a gas station…hmm, this could be used in combination with a certain debit accepting colored card.


I always like to include BofA Privilege – with 75% bonus = 5.25%.

I recall hearing a year back or so that they cracked down on people pumping the gas.

Sally Mae is gone. Sam’s club is gone. Fort Knox is still here.

Oop. Sam’s isn’t gone. But it does require membership. Which isn’t free.


Can anyone confirm that they are able to use this for gas station purchases for gift cards and still code as gas? PenFed only works at the pump and purchases inside does not qualify.

They tell you if you are pre approved over the phone after submitting an application online. It sounds like they don’t actually pull credit until after you become a member.

After doing some digging around, it seems like this card is not actually 1% back on everything else, but only on “general retail” purchases – an extremely vague term that includes some codes but not all.


This post should be updated to remove the Sallie Mae card recommendation. It doesn’t appear to be available any longer.


Is there a business version of this card or another business CC which gets unlimited 5% on gas? I don’t see one in


How is the cash back redeemed? Deposit? Statement credit? What is the increment? Is it automatic or do I need to manually redeem the cash back?

this card gives 5% cash back on all purchases that are labelled “Automotive” Car repair payments also give 5% cash back.
