On our record, with no source quoted

Our record names an oil for these countries, but the record does not quote where the chain says it. We show them apart so you can tell the two kinds of row apart.

Country	Fryer oil on our record
Canada	Peanut oil What our record says 100% refined peanut oil (fries - the only fried item); burgers/hot dogs are griddled, not fried
U.S.	Peanut oil What our record says 100% refined peanut oil (all fried items; dedicated fry-only fryers)
UK	Peanut oil What our record says refined peanut oil, the only oil used in the fryers (fries are the only fried item); rapeseed oil in mayonnaise, palm/rapeseed vegetable fat blend in the hot dog bun

Why does the oil change at the border?

The chain does not say. None of the pages we read gives a reason for using one oil in one country and a different one in the next. So we ask the question and leave the answer open: if Five Guys can fry in one oil there, why not here?

What we can say for sure is narrower. Each row is what the chain published for that country, read on or before October 13, 2026. A statement can be years old, so open "What our record says" for the wording and any caution we noted. Spot one that is out of date? Tell us in the app with "Wrong? Let us know" on that chain.
