• Brake fluid replacement is mandatory every 2 years, regardless of mileage
• Under severe duty (dusty roads, short trips below freezing, extended idling), change engine oil at 4,000 miles
• The 2.9L Quadrifoglio V6 has distinct maintenance requirements: spark plugs at 30,000 miles and carbon ceramic brake disc inspection after intensive use

How the Scheduled Servicing System Works

The 2018 Alfa Romeo Giulia follows a structured maintenance plan based on both distance and time, as detailed in the owner's manual . Correct servicing is crucial for guaranteeing a long life for the vehicle under the best conditions.

Oil Change Indicator System:

The actual interval for changing engine oil and replacing the engine oil filter depends on vehicle usage conditions and is signaled by the warning light or message in the instrument panel . The system adapts based on your driving habits to determine oil life - it may trigger as early as 3,500 miles under severe conditions . In all cases, never exceed 1 year or 10,000 miles (16,000 km) .

Critical Warranty Note:

Scheduled Servicing intervals are required by the Manufacturer. Failure to have them carried out may invalidate the New Vehicle Limited Warranty . You are advised to inform your authorized dealer of any small operating irregularities without waiting for the next service.

Plan Notation:

• (o) Recommended operations - suggested for optimal vehicle health
• (mandatory) Mandatory operations - required to maintain warranty coverage

Owner Periodic Checks (Between Services)

The following checks are the owner's responsibility between professional service visits. These should be performed every month or every 600 miles (1,000 km) or before long trips :

Engine Oil Level:

Every 2,000 miles (3,000 km) , check and top off the engine oil level if required .

Heavy Usage & Severe Duty Conditions

If the vehicle is used under any of the following conditions, more frequent maintenance is required :

Checks Required More Frequently Under Heavy Usage :

• Check cleanliness of hood and trunk locks, cleanliness and lubrication of linkage
• Visually inspect conditions of: engine, transmission, pipes and hoses (exhaust/fuel system/brakes) and rubber elements
• Check battery charge and battery fluid level (electrolyte)
• Visually inspect conditions of the accessory drive belts
• Check and, if necessary, change engine oil and replace oil filter
• Check and, if necessary, replace cabin air filter
• Check and, if necessary, replace air cleaner

Severe Duty Oil Change Requirement :

Change engine oil at 4,000 miles (6,500 km) if the vehicle is operated in a dusty and off-road environment or is operated predominately at idle or only very low engine RPMs. This type of vehicle use is considered Severe Duty.

Factory Maintenance Plan - 2.0L Engine

The following maintenance plan is extracted from the official 2018 Alfa Romeo Giulia Owner's Manual :

Regular Inspections (Every 10,000 miles / 1 year)

Major Service Items (By Mileage/Time)

Engine Oil Change Guidance

Maximum Intervals :

• Never exceed 10,000 miles (16,000 km) between oil changes
• Never exceed 12 months between oil changes
• The warning light may indicate a need for earlier changes based on driving conditions

Oil Capacity :

• 2.0L engine: Approximately 5.2 liters (5.5 quarts)
• 2.9L Quadrifoglio: Approximately 7.0 liters

Oil Specification:

The 2.0L Multiair engine is sensitive to oil quality - the system uses oil for hydraulic valve actuation. Use synthetic oil meeting FCA specifications listed in your owner's manual.

Severe Duty:

Under dusty/off-road conditions or predominant idle/low RPM operation, change oil at 4,000 miles .

Spark Plugs - Critical 2018-Specific Information

The 2018 Giulia 2.0L has a 30,000-mile spark plug interval. This differs from 2019+ models which have a 60,000-mile interval for the same engine and same spark plugs .

Why the Difference :

• The 2017-2018 model years specify 30,000-mile spark plug replacement in the owner's manual
• The 2019 model year specifies 60,000-mile replacement using the same spark plug (Part # 68292346AA)
• Alfa Romeo accumulated real-world use data and extended the interval for newer models
• However, the 2018 maintenance schedule remains unchanged by the manufacturer

Owner Recommendation :

Many owners and dealers recommend sticking with the 30,000-mile interval even if some dealers now consider 60,000 acceptable. One owner who changed plugs at 60,000 miles reported they were "very very worn" and stated, "I will change my plugs at around 30,000 miles next time" .

Recommended Spark Plugs :

• NGK 90219 (ILZKR7G7G) - OEM plugs for the 2.0T engine
• Same plugs used in the Jeep 2.0T engine, available at local parts stores

Quadrifoglio (2.9L V6):

For the 2018 Giulia Quadrifoglio, the spark plug replacement interval is 30,000 miles .

Accessory Drive Belt (Not Timing Belt)

Important Note on Terminology: Unlike some other Alfa Romeo models with timing chains or belts, the 2018 Giulia 2.0L uses accessory drive belts (serpentine belts) that require regular replacement. This is different from a timing belt, though the maintenance schedule refers to accessory drive belt(s).

Factory Replacement Intervals :

Accessory Drive Belt Inspection:

Visual inspection of belt condition and tensioning is required at every scheduled service (every 10,000 miles) .

Brake Fluid

Brake fluid replacement is a mandatory operation that must be done every 2 years, irrespective of mileage .

Why Every 2 Years:

Brake fluid is hygroscopic - it absorbs moisture from the air over time, which lowers the boiling point and can cause brake fade under hard braking. Moisture also promotes internal corrosion of brake system components.

Check Frequency:

Brake fluid level should be checked every month or every 600 miles. If insufficient, see an authorized dealer as soon as possible .

Engine and Cabin Air Filters

Engine Air Cleaner Cartridge :

• Normal conditions: Replace per maintenance schedule (shown at 36,000-mile/4-year intervals)
• Dusty areas: Replace every 10,000 miles (16,000 km)

Cabin Air Filter :

• Normal conditions: Replace every other scheduled service (approximately 20,000 miles)
• Dusty areas: Replace every 10,000 miles (16,000 km)

Transmission and AWD Service

Transfer Case Oil (AWD Models Only) :

AWD models require transfer case oil replacement according to the mandatory maintenance schedule.

Transmission Service:

While not listed with a specific mandatory change interval in the 2018 maintenance summary, the ZF 8-speed automatic transmission benefits from fluid inspection. Many independent technicians recommend a drain-and-fill between 50,000 and 80,000 miles for long-term reliability, especially for vehicles driven in severe conditions.

Scheduled Transmission Inspection:

The engine control system operation check (via diagnostic tool) at each service includes transmission-related diagnostics .

Engine Coolant

Engine coolant replacement is listed as a mandatory operation in the maintenance plan . Coolant level should be checked monthly (every 600 miles) and topped off as needed .

Quadrifoglio (2.9L V6) Specific Information

The high-performance Quadrifoglio variant has distinct maintenance requirements :

Carbon Ceramic Brake Discs (if equipped) :

• The actual interval for changing brake pads and carbon ceramic brake discs depends on vehicle usage conditions
• Replacement is signaled by the warning light or message on the instrument panel
• It is advisable to check brake disc weight and thickness after each intensive use

Brake Disc Wear Status Check:

The maintenance plan includes checking brake disc wear status with a diagnostic tool and visually inspecting the brake discs surface and edge .

Maintenance Plan Summary Table (2.0L)

*(o) = Recommended operation, (mandatory) = Mandatory operation*

Note: The accessory drive belt replacement at 60,000 km (36,000 miles) and 120,000 km applies - confirm exact timing with your authorized dealer based on your vehicle's usage conditions .
