2018 Mazda6 Maintenance Schedule
This is the model year the turbocharged SKYACTIV®-G 2.5T joins the Mazda6 and the spark plug row splits in two, and the model year the air filter, cabin air filter and tire rotation stop being performed at the oil change and become fixed marks on the grid. This page states that model year’s own two tables and no other year’s.
What Is Different About This Model Year
The reason this model year has its own page instead of being read off another Mazda6’s.
Mazda Published This Table for This Model Year Alone
Mazda revised the published schedule at this model year. It revised it again at the next one, so this table belongs to this model year and to no other. What that means for the table below is set out in the cards that follow.
The Spark Plug Row Splits by Engine
Mazda prints two rows for this model year: replace every 64,000 km (40,000 miles) on the SKYACTIV®-G 2.5T, and replace every 120,000 km (75,000 miles) on every other engine. The model year before it prints a single row and a single figure, which is the kind of difference that turns one plug change into an argument at the counter. Neither row carries a month figure, so neither is given one here.
Three Rows Move onto the Grid
The Schedule 1 air filter becomes every 22,500 miles or 36 months and the cabin air filter every 15,000 miles or 24 months, both marked at fixed columns rather than performed at the oil change; the tire rotation becomes a printed sentence, rotate every 12,000 km (7,500 miles); and the severe rotation becomes a printed every 8,000 km (5,000 miles). The model year before publishes only a ceiling for those rows.
No Diesel Block
This model year’s tables carry no SKYACTIV®-D 2.2 rows at all. Mazda adds a full diesel block — air filter, fuel filter, exhaust fluid, glow plug and a diesel drive-belt row — to the model year after it, so a page built from that one would describe equipment this car’s manual never mentions.
What Did Not Move After This
This is the earliest Mazda6 model year whose stated intervals match the tables Mazda printed for the rest of the nameplate: a Schedule 1 ceiling of 12 months or 7,500 miles, a 22,500-mile air filter, a 15,000-mile cabin air filter on the normal table and 25,000 miles on the severe one. What changes after it is which rows exist, not what they say.

What Mazda asks for at your mileage

Updates Mazda has issued for your car

What was done, and what comes next
Schedule 1 — Normal Driving
This model year’s 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 2018 Mazda6 owner’s manual, document Mazda6_8GU3-EA-18A_Edition3, section pages 467 to 472, and from no other model year’s manual. The Canada residents routing printed in the same section is out of market here. Your own manual is the authority for your vehicle; bring the mileage and our team will read the table with you.
Which Schedule Applies to Your Mazda6
On this model year 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 this model year.
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.

Why This Model Year Has Its Own Page
The spark plug row splits here: 40,000 miles on the SKYACTIV®-G 2.5T and 75,000 miles on every other engine, where the model year before it prints one row for all of them. The air filter moves to 22,500 miles and the cabin air filter to 15,000 miles on fixed marks rather than at the oil change, and no diesel rows appear on this table at all.
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 this model year’s 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.
2018 Mazda6 Maintenance Schedule Questions
When are the spark plugs replaced on a 2018 Mazda6?⌄
Mazda splits the row for this model year: 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, so this page states the mileage and stops there.
What is the maintenance schedule for a 2018 Mazda6?⌄
Mazda prints two tables for this model year. 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 2018 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. The 25,000-mile severe figure is the Mazda6’s own and holds across the nameplate.
When is the brake fluid replaced on a 2018 Mazda6?⌄
Mazda does not schedule a brake fluid replacement for this car. Its tables carry a brake and clutch fluid level inspection on the severe schedule and no replacement row at all. Where Mazda publishes nothing, this page states nothing and our service team will inspect and advise.
How much is maintenance for a 2018 Mazda6 at Dean McCrary Mazda?⌄
