MG3 Running Costs — Australia

✓ Technically reviewed by Daniel Wei Chen — Senior Chinese Automotive Diagnostics & Repair Specialist, Sydney, Australia · 19 August 2026.

The MG3 is one of the cheapest cars in Australia to keep on the road: $1,827 (CVT) or $1,921 (Hybrid+) in capped servicing over five years, and — unlike every MG HS and the ZS Hybrid+ — the whole MG3 range runs on cheap RON 91, hybrid included. The hybrid’s official figures are striking: 4.3 L/100km combined and 0.9 L/100km urban — town driving is where it earns its premium back.

*Australian Government Green Vehicle Guide (greenvehicleguide.gov.au, retrieved 19 August 2026). GVG’s annual cost assumes 14,000 km/year at last-quarter average retail fuel prices; litres-per-year is our arithmetic on the official figure at 15,000 km/year — both assumptions stated so you can rescale to your own mileage. The hybrid’s 0.9 L/100km urban figure is a laboratory number — treat it as “the hybrid is at its best in town”, not a promise.

The RON 91 advantage: the MG3 Hybrid+ accepts RON 91 while the ZS Hybrid+ and every HS require RON 95. If you’re choosing between MG’s small hybrids, that pump-price gap compounds the MG3’s lower consumption.

Warranty — Australia

10 years / 250,000 km new-car warranty with roadside assistance on current models. Older cars (2011–2024 fleet) carry the warranty terms in force when sold — most are now out of warranty, which makes the known-problems checklist and correct fluid specs the real cost-control tools.
