Every trim takes regular — no premium needed.
Is the 2011 Cadillac SRX 2WD good on gas?
At up to 20 MPG combined, the 2011 Cadillac SRX 2WD is about average for a Sport Utility Vehicle - 2WD — that class averages about 18.8 MPG across 1,619 EPA-tested versions, so it's middle-of-the-road for its size.
Real-world MPG vs the EPA number
The EPA figures above come from a standardized dynamometer test, not the open road — real-world MPG typically runs a bit lower depending on your driving, climate and terrain. That's true of every car on this site, old or new.
EPA updated its fuel-economy equations again for model year 2017 — mostly affecting hybrids and turbocharged engines — and recalculated 2011-2016 ratings to match, in some cases 1-2 MPG lower. The number above already reflects that update.
At today's AAA national average price — $3.80/gal for regular gas as of 2026-07-05 — the most efficient trim runs about $2,850/year (roughly $238/month, about $19.00 per 100 miles) at the EPA's assumed 15,000 miles/year, using an estimated 750 gallons a year. We don't estimate a cost-per-fill since exact tank size isn't in the public EPA dataset, but the per-100-mile figure scales to any tank. Current national average gas prices →
