Maserati GranTurismo Maintenance Schedule: Professional Standard, Intervals, and Budget

1. Purpose and Scope

This document consolidates verified intervals and the list of operations for servicing the Maserati GranTurismo with a focus on gasoline versions (the generation with the V8 F136 and the current generation with the V6 Nettuno), and provides guidance on costs, fluid replacement frequency, and consumables. The goal is to offer a structured Maserati GranTurismo service plan that can be adapted to actual operating conditions (city/highway, temperature range, driving style) and to a specific VIN.

2. Basic Principles for Building the Schedule

“Time or mileage” criterion. For most modern Maserati models, including GranTurismo, the rule is an annual service or approximately every 12–12.5k miles (~19–20k km) — whichever comes first. On later models, a service indicator controls the interval and notifies you ahead of time.

Accumulative structure. Each “major” interval includes all items from the basic annual service plus additional work (brake fluid/cabin filter at 2 years; spark plugs on some lines at 3 years; engine air filter and inspection/replacement of belts at 4 years). This framework appears in typical Maserati dealer schedules.

Adaptation by model/generation. For the previous-generation Maserati GranTurismo (V8 F136) and the current one (V6 Nettuno Modena/Trofeo; and Folgore), some items can differ (for example, spark plug replacement cadence for part of the V8 lineup). Check the manual for your specific year/engine.

Official programs. Maintenance Premium (covers the first three service visits) and Maintenance 10 (from the 4th to the 10th service) are available; they lock in the scope of work and the cost approach.

3. Consolidated Schedule: Maserati GranTurismo (Overview)

Below are typical intervals used in Maserati dealer practice that can serve as a baseline planning matrix for servicing the Maserati GranTurismo. Verify specifics for your VIN and engine against the service booklet and owner’s manual.

• Every year / ~12–12.5k miles (~19–20k km) — basic annual package (oil, oil filter, comprehensive inspections/diagnostics).
• Every 2 years / ~25k miles — annual package + brake fluid flush/replacement and cabin filter.
• Every 3 years / ~37.5k miles — annual package + spark plugs (depending on generation/engine; see Section 6).
• Every 4 years / ~50k miles — year-2 package + engine air filter + inspection/replacement of drive belts based on condition.
• After year 4 — repeat the cycle with adjustments based on the actual condition of assemblies.

4. Interval Contents: List of Operations

4.1. Annual service (12–12.5k miles or 12 months)

Mandatory operations:

• Engine oil replacement (approvals for the specific engine) and oil filter.
• Checking level/condition of coolant, brake fluid, and washer fluid.
• Inspection of brake mechanisms (discs/pads, hoses/lines, calipers).
• Suspension inspection (bushings, joints, shock absorbers), steering.
• Tire check (wear/pressure/rotation as needed), lighting.
• Electronics/engine diagnostics, belts/idlers check, leak inspection.

For some dealers, the annual package also includes short road tests and software updates (as needed).

4.2. Two-year interval (~25k miles)

In addition to the annual package:

• Brake fluid flush and replacement.
• Cabin (dust/pollen) filter replacement.

For older GranTurismo models, dealers often recommend checking brake fluid every year, but with mandatory replacement no less than once every two years.

4.3. Three-year interval (~37.5k miles)

In addition to the annual package:

• Spark plugs (see the note on generation differences in Section 6).

4.4. Four-year interval (~50k miles)

In addition to the two-year package:

• Engine air filter.
• Inspection/replacement of drive belts and, as indicated, idlers.

5. Additional Assemblies and Fluids (Recommendations)

AT/transfer units/differentials: preventive fluid renewal at “large” intervals improves smoothness and longevity (in dealer practice, ~60–65k miles for AT and ~50–60k miles for differentials are common reference points; confirm requirements for your transmission).

Coolant: check at every annual visit; replace based on condition or within “major” intervals.

A/C system: check tightness/performance; service as per diagnostics.

Brake discs/pads: decide based on remaining thickness, evenness of wear, runout/overheating.

(The approaches listed align with general Maserati dealer logic and specialist workshop practice; reconcile specifics with your model/year manual.)

6. Generation- and Powertrain-Specific Notes

6.1. GranTurismo (new generation, from MY 2023/2024)

Engines: V6 Nettuno (Modena/Trofeo) with different power levels; separately — Folgore (BEV).

Service logic: annual interval/12–12.5k miles; two-year — brake fluid and cabin filter; three-year — spark plugs; four-year — engine air filter and belts. Although this framework is formed using the V6 line (Ghibli/Levante/Quattroporte) as reference, dealers apply it as a baseline for the current GranTurismo as well; confirm specifics for your VIN.

6.2. GranTurismo (previous generation, V8 F136)

Annual/two-year intervals are analogous (oil/filter; brake fluid + cabin filter).

Spark plugs: for part of the V8 range (GT/MC Stradale, etc.) there is a recommendation for much less frequent plug replacement — roughly once in the 12th year, which distinguishes the GranTurismo from other Maserati models. Verify in your year/engine manual.

Additional annual items: some dealer cards for older GranTurismo models call for annual brake fluid replacement and extended diagnostic procedures (with Maserati scan tool), as well as inspection of drive belts and auxiliaries.

Note on Folgore (BEV): absence of an ICE reduces engine fluids (no engine oil), but brake fluid, thermal management for power electronics/battery, brake mechanisms, and tires require regular checks. For the electric version, follow the official manual with mileage/time considerations.

7. Operational Checks Between Intervals

For the Maserati GranTurismo, it is reasonable to add short regular checks: brake fluid level/condition, tire pressure, coolant level, washer fluid; wiper blade and exterior lighting inspection. Some dealers advise checking engine oil level roughly every ~1,900 miles and performing a basic inspection before long trips.

8. Cost Benchmarks: What to Plan in the Budget

Actual figures depend on region, exchange rates, dealer/independent shop pricing, and the scope of work in a given visit. Typical public calculators and independent reviews give the following ranges:

• Annual service for older GranTurismo models — approximately $1,400–2,000 per year (oil/filters/inspections).
• “Major” interval (e.g., with belts and plugs in the package) for older V8s — can reach ~$3,000 depending on parts list and labor.
• Aggregate 10-year costs for GranTurismo (average estimates including scheduled maintenance + repairs) — about $21,324, with an estimated probability of a major repair ~55.82% within 10 years. These are guidelines, not fixed values; they vary with age, driving style, mileage, and region.

Official Maintenance Premium / Maintenance 10 programs allow you to lock in part of the costs and ensure that the schedule is followed per manufacturer specifications.

Note: public calculators for related Maserati models (Ghibli/Levante/Quattroporte) show that two-/three-/four-year intervals are notably more expensive than annual ones due to extra operations (brake fluid, plugs, belts/air filters) — the same logic applies to the GranTurismo.

9. Consumables and Specifications

For Maserati GranTurismo service, use only fluids/parts approved for the specific engine/year:

• Engine oil — viscosity class/approvals from the manual.
• Brake fluid — replace at least once every 24 months; for older models, annual recommendations may exist.
• Coolant — type/specification per the manual; check at every annual service.
• Filters (oil, air, cabin) — correct geometry and flow capacity.
• Spark plugs — heat range/gap per documentation; interval depends on generation.
• Drive belts/idlers — inspect every year, replace at the “fourth-year” interval or based on condition.

11. Differences by Powertrain Type

11.1. V6 Nettuno (Modena/Trofeo)

• Service intervals — per the baseline matrix above.
• Key emphasis — timely replacement of oil/filters and adherence to timing for brake fluid and spark plugs.
• Fluid and plug specifications — per the manual for the relevant year.

11.2. V8 F136 (previous generation)

• Annual service cost is usually higher than for some other Maserati models due to V8 packaging and access specifics.
• For some variants, the spark plug replacement interval is notably longer (roughly year 12). Verify in the manual.

11.3. Folgore (BEV)

• No engine oil/spark plugs; brake fluid, battery/inverter cooling, tires/brake mechanisms remain.
• Work periodicity — per the service documentation for the electric version (VIN-specific).

12. Frequently Asked Questions (FAQ)

Can I extend the interval if my yearly mileage is low?
No. Fluids age over time; stick to the annual term even with low mileage. On later cars, the service indicator will prompt you.

Why do some sources list 12,000 or 12,500 miles?
It’s the difference between local schedules and rounding. A practical guidepost is once a year or ~12–12.5k miles, consistent with dealer materials.

How much should I budget per year?
For older GranTurismo models, typical annual service estimates are $1,400–2,000, and major intervals are costlier due to belts/plugs/expanded scope. For the new generation, confirm amounts with your dealer/shop.

Are prepaid programs worthwhile?
Yes, Maintenance Premium (first 3 services) and Maintenance 10 (4th–10th services) help plan expenses and ensure work per the schedule.

What operational checks should I do between services?
Check tire pressure, engine oil level (about every ~1,900 miles), and inspect fluids and lighting before long trips.
