Card routing at a store
Which credit card should I use at Shell? (2026)
By the Pikt editorial teamCard rates checked against issuer termsPublished Updated
Estimates use Pikt's card catalog and the same rewards engine as Pikt Checkout. Pikt personalizes each estimate to the cards you already carry, the purchase details, and any reward values you set. It learns from confirmed card choices over time, while verified rewards math remains the basis for the result and the explanation.
Pikt tells you which card to use
Most card lists rank cards you could open. Pikt compares the cards you already carry at Shell, then shows the estimated dollar difference and why the recommendation fits.
This is personal card routing: match each purchase to the right card from your wallet. Pikt recommends the card; you still pay with it yourself.
The general dollar comparison
This reference answer uses published terms, not your wallet. Your result can change with the cards you carry, reward values, eligible offers, and what you usually use.
On a $62 Shell purchase, Sapphire Preferred is likely to earn the most: 3x points, about $3.81. Citi Strata is next at $3.53, so the difference on this one purchase is $0.28. Sapphire Preferred carries a $95 annual fee, which this one purchase does not cover on its own. This is a general ranking of 200+ personal cards. General rankings use published card terms and do not use the cards in your wallet. Card Check personalizes the estimate to cards you already carry.
Why the answer can change at Shell
Shell stations, which code as gas. One card in Pikt's catalog, Shell's own card, carries a Shell-specific rate on top of its gas rate.
Pikt classifies Shell as gas, so the ranking below uses each card's rate for that category plus any rate a card has for Shell itself.

Points are turned into dollars at Pikt's estimate of what they're worth when moved to an airline or hotel partner, so a points card and a cash-back card can sit in the same column. In the app, Pikt starts from the lower travel-site value until you tell it how you redeem, so your own answer can rank points cards lower than this table. Point values are estimates, mostly from The Points Guy's monthly valuations (September 2026) plus issuers' own published redemption rates. Welcome bonuses, spending caps, and card-specific credits are not included in this one-purchase number.
Annual fees as of October 2026. Issuers change terms often, so check the issuer's own page before you apply.

How Pikt got this answer
Pikt ran 200+ personal cards through the same rewards engine as Pikt Checkout. Each card is open to new applicants, and its earn rates have been checked against issuer terms. The example uses a $62 purchase classified as gas at Shell. Points and cash back are converted to dollars. Read how Pikt turns points into dollars.
The store's category code, not the aisle, decides which bonus applies. Business cards, cards no longer open to new applicants, and cards whose rates Pikt has not verified are left out.
