Mazda Mazda3 Oil Capacity & Oil Type
TL;DR
Capacity ranges from about 4.2 to 5.1 L (4.4 to 5.1 US qt) depending on engine generation - always confirm with your specific engine code before filling.
Mazda3 Oil Capacity by Engine Generation
The Mazda3 has been built with several different engine families since 2004, and oil capacity changes noticeably between them. The figures below come from Mazda service data and verified oil-lookup sources for each specific engine code, not a single blanket number for the whole model line.
First and second generation (2004-2013)
Early Mazda3 models (chassis codes BK and BL) used the MZR 2.0L and 2.3L engines, and later the 2.5L L5-VE. These engines specified 5W-20 conventional or synthetic oil, with 0W-20 phased in for the 2.5L starting around 2011.
Third and fourth generation Skyactiv-G (2014-present)
From the 2014 model year onward (chassis codes BM, BN and BP), Mazda3 switched to Skyactiv-G 2.0L (engine code PE-VPS) and 2.5L (PY-VPS) engines specifying 0W-20 for the US/Canada market. The turbocharged 2.5L (PY-VPTS), offered from 2021 on Turbo trims, uses 5W-30 instead and holds slightly more oil.
Data table
| Engine code / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| 2.0L / 2.3L MZR (L3, LF) - 2004-2009 | 4.3 L / 4.5 US qt | 5W-20 |
| 2.0L MZR - 2010-2013 | 4.3 L / 4.5 US qt | 5W-20 |
| 2.5L L5-VE - 2010-2013 | 5.0 L / 5.3 US qt | 5W-20 (2010), 0W-20 (2011-2013) |
| Skyactiv-G 2.0L (PE-VPS) - 2014-present | 4.2 L / 4.4 US qt | 0W-20 |
| Skyactiv-G 2.5L (PY-VPS) - 2014-present | 4.5 L / 4.8 US qt | 0W-20 |
| Skyactiv-G 2.5L Turbo (PY-VPTS) - 2021-present | 4.8 L / 5.1 US qt | 5W-30 |
Why the number varies
Engine generation matters more than model year alone, since Mazda kept selling older engines alongside newer ones for a year or two during transitions. Two Mazda3s built the same year can use different engines depending on trim, so always match the capacity to your actual engine code rather than just the model year.
Confirm before you fill
The number that matters for your car is the one printed for your specific engine. Before topping off or doing an oil change, check your owner's manual (maintenance or specifications section) and the oil filler cap or dipstick markings under the hood, since these reflect the exact build of your vehicle.
- Owner's manual - maintenance/specifications chapter
- Oil filler cap and dipstick - printed viscosity and quick reference
- Dealer service data - by VIN, the most precise source

Frequently asked questions
How much oil does a 2.0L Mazda3 take with a filter change?
The Skyactiv-G 2.0L (2014-present, engine code PE-VPS) takes about 4.2 liters (4.4 US quarts) of 0W-20 with a new filter. Older 2004-2013 non-Skyactiv 2.0L engines take about 4.3 liters (4.5 US quarts) of 5W-20 instead, so check which generation you have.
Does the 2.5L Mazda3 use the same oil capacity as the 2.0L?
No. The Skyactiv-G 2.5L (PY-VPS) holds about 4.5 liters (4.8 US quarts) of 0W-20, more than the 2.0L's 4.2 liters, because it is a larger displacement engine with a bigger oil pan and sump.
Is the turbocharged Mazda3 oil capacity different?
Yes. The 2.5L Turbo (engine code PY-VPTS, offered from the 2021 model year on Turbo trims) takes about 4.8 liters (5.1 US quarts) of 5W-30, slightly more oil and a heavier viscosity than the naturally aspirated 2.5L, reflecting its added oil cooling needs.
Where can I find the exact oil capacity for my specific Mazda3?
Check your owner's manual's maintenance or specifications section, which lists the figure for your exact engine and market, or look at the printed markings on the oil filler cap and dipstick under the hood.
