2020 Mazda6 Maintenance Schedule
Mazda did not revise the Mazda6’s published schedule for this model year: it reads the table Mazda printed across 2019–2020, unchanged from the model year before it. These two model years share one schedule: once the print stamp is stripped, Mazda’s U.S. section is identical between them. They are also the Mazda6 tables that gain a SKYACTIV®-D 2.2 diesel block, and their severe cabin air filter stays at 25,000 miles where a showroom neighbour’s moved. This page states these model years’ own two tables and no other year’s.
What Changed From the Model Year Before
Nothing — and that is the answer most owners are here for, so this page says it plainly rather than leaving you to compare two tables line by line.
Nothing Moved From the Model Year Before
Mazda carried its published Mazda6 schedule into this model year unchanged. Every interval below is the table Mazda printed across 2019–2020, read for the 2020 model year. The boundaries in this nameplate’s published schedule were established one model year at a time before any of these pages were written, so “unchanged” here is a finding rather than an assumption — which is the difference between this page and a schedule reprinted under a different year.
This Is the Second of Two Model Years on This Table
Mazda published the same schedule for 2019–2020. This is the last of them: the model year after it moves to a different table and has its own page, and no figure below is carried forward to it.
Where the Change Actually Is
The 2019–2020 table opens at the 2019 model year, and that model year’s own page sets out what Mazda moved at the boundary. Between it and this model year the published schedule did not move, so there is no boundary to describe here and none is invented.
What This Page Will Not Do
It does not restate a neighbouring model year’s figures. Every interval below comes from this model year’s own entry in Mazda’s published Mazda6 schedule, and where Mazda publishes nothing this page states nothing rather than filling the gap from the model year either side of it — a figure carried one model year in either direction is wrong in a way nothing about the page would show.
How These Model Years’ Table Is Built

What was done, and what comes next
Schedule 1 — Normal Driving
These model years’ normal-driving table, grouped by the interval Mazda marks each row at.
Sourced from the Scheduled Maintenance (U.S.A., Canada, and Puerto Rico) section of the 2019 Mazda6 owner’s manual, document Mazda6_8HR2-EA-19E_Edition1, section pages 486 to 492, confirmed identical in the 2020 manual and against Mazda’s independently printed scheduled-maintenance document Mazda6_8HK6-EA-19A_Edition1 — three printings, one schedule, which is why these two model years share one page. No other model year’s manual was used. Your own manual is the authority for your vehicle; bring the mileage and our team will read the table with you. For this model year specifically, Mazda’s own book is document Mazda6_8HX3-EA-19I_Edition2_old — the one to check your vehicle against.
Which Schedule Applies to Your Mazda6
On these model years the answer is a property of the whole car, not of one row.
Mazda’s Own Condition List
Repeated short-distance driving; driving in dusty conditions; driving with extended use of brakes; driving in areas where salt or other corrosive materials are used; driving on rough or muddy roads; extended periods of idling or low-speed operation; driving for long periods in cold temperatures or extremely humid climates; driving in extremely hot conditions; driving in mountainous conditions continually. Mazda prints: follow Schedule 1 if none of these apply, and if any do apply, follow Schedule 2.
It Is the Whole Car, Not One Row
On this car a single condition moves the entire schedule to Schedule 2 — the oil, the disc brakes and every chassis row with it. Mazda’s newer books do something different and map each condition to specific items, leaving every other row on its normal interval. Two different models of severe service, and neither may be written the other one’s way.
Flexible and Fixed Are a Separate Question
Mazda’s flexible engine-oil maintenance is available to U.S.A. and Puerto Rico residents whose car is not operated with extended periods of idling or low-speed operation, such as a police car, taxi or driving-school car, and is not driven in dusty conditions. Where either applies, fixed maintenance is followed — engine oil and filter every 5,000 miles or 6 months — even on Schedule 2.
Rows That Are Not for This Market
Mazda routes Canada residents to Schedule 2 outright. That is a market routing rather than a statement about how a car is driven in Mobile, and it is not quoted as one here. Which of the two U.S. tables your Mazda6 is on is a question about how it is driven, and our service team will go through the condition list with you.
Schedule 2 — Severe Driving
The severe-driving table for these model years, gasoline rows and diesel rows kept apart.
Every 5,000 Miles or 6 Months
Engine oil and filter on the fixed basis, disc brakes, engine coolant level, brake and clutch fluid level, tire inflation pressure and tire wear, function of all lights, all locks and hinges lubricated, and washer fluid level. Tire rotation runs at the same cadence and is printed as a sentence: rotate every 8,000 km (5,000 miles).
Every 15,000 Miles or 18 Months
Fuel lines and hoses, brake lines, hoses and connections, steering operation and linkages, front and rear suspension with ball joints and wheel bearing axial play, driveshaft dust boots, and the bolts and nuts on the chassis and body. The same rows sit at every 15,000 miles or 24 months on Schedule 1 — the mileage matches and the month figure does not, which is exactly why the two tables are quoted separately.
Cabin Air Filter — 25,000 Miles
Mazda prints, on these model years’ Schedule 2: replace every 40,000 km (25,000 miles) or 2 years. That is the Mazda6’s own figure and it holds in every model year from 2014 to the end of the nameplate. It is not the figure Mazda prints for every showroom neighbour of the same era, so a severe cabin filter borrowed from one is wrong for this car. Schedule 1 replaces the cabin air filter every 15,000 miles or 24 months.
The Longer Severe Rows
Every 20,000 miles or 24 months — drive belts. Every 30,000 miles or 36 months — air filter, and hoses and tubes for emission. At 35,000 miles or 42 months, once — exhaust system and heat shields. Spark plugs and engine coolant carry the same figures they carry on Schedule 1, and the emergency flat tire repair kit is inspected annually. Mazda adds one note to the severe air filter row: if the vehicle is operated in very dusty or sandy areas, clean and if necessary replace the air filter more often than the recommended intervals.
The Diesel Rows Mazda Printed
These model years’ U.S. tables carry a SKYACTIV®-D 2.2 block that the model year before them does not: a diesel air filter cleaned and replaced across the Schedule 1 columns, a diesel fuel filter replaced every 22,500 miles on Schedule 1, diesel exhaust fluid for the SCR system, a glow plug row footnoted rather than scheduled, and a diesel drive-belt row. Whether a diesel Mazda6 was ever delivered to a U.S. customer is a separate question this page does not answer — the rows are recorded because Mazda printed them, and none of them applies to a gasoline car.

Why These Model Years Have Their Own Page
They share one table — Mazda’s U.S. section is identical between them — and it is the Mazda6 table that carries the SKYACTIV®-D 2.2 diesel block. Its severe cabin air filter stays at 25,000 miles, which is the figure most likely to be corrupted by borrowing from a showroom neighbour whose own figure moved in exactly these years.
Schedule 1 and Schedule 2
Schedule 1 is the normal-driving table and hangs off a maximum interval of 12 months or 7,500 miles. Schedule 2 is the severe-driving table and marks its shortest rows at 6 months or 5,000 miles. On these model years’ wording a single severe condition moves the whole car onto Schedule 2.
Booking and Pricing
Service pricing moves, so it lives on the service offers page rather than being written into this one — what you read there is current. Book through the service scheduler, or see the rest of what we do at the Mazda service center.
2020 Mazda6 Maintenance Schedule Questions
What is the maintenance schedule for a 2019 or 2020 Mazda6?⌄
One schedule covers both. Schedule 1, for normal driving, hangs off a maximum interval of 12 months or 12,000 km (7,500 miles). Schedule 2, for severe driving, runs on a grid of 6 months and 5,000 miles. Which of the two applies is settled by Mazda’s own condition list rather than by preference.
How often is the cabin air filter replaced on a 2019 or 2020 Mazda6?⌄
Every 15,000 miles or 24 months on Schedule 1. On Schedule 2 Mazda prints: replace every 40,000 km (25,000 miles) or 2 years. That severe figure does not move between these two model years, and it is the Mazda6’s own rather than a figure shared with other Mazdas of the same era.
When are the spark plugs replaced on a 2019 or 2020 Mazda6?⌄
Mazda splits the row by engine: every 64,000 km (40,000 miles) on the SKYACTIV®-G 2.5T, and every 120,000 km (75,000 miles) on every other engine. Mazda publishes a mileage and no month figure for either row.
Do the diesel rows apply to my Mazda6?⌄
Only to a SKYACTIV®-D 2.2 car. Mazda printed a full diesel block in these U.S. manuals — a diesel air filter, fuel filter, exhaust fluid, drive belts and a glow plug row — and none of it applies to a gasoline Mazda6. Bring the car and we will confirm which rows are yours before anything is quoted.
How much is maintenance for a 2019 or 2020 Mazda6 at Dean McCrary Mazda?⌄
