2. Industry Development Trends: Active Maintenance, New Energy Vehicles, and Product-as-a-Service
Based on analysis of corporate annual reports (Liqui Moly, SONAX, WURTH GROUP, 3M), industry news from Q4 2025 to Q2 2026, and automotive aftermarket trends, four dominant trends shape the automobile maintenance fluids sector:
2.1 From Passive Maintenance to Active Management
As the number of cars on the road continues to rise, consumers are paying more and more attention to car maintenance. Oil maintenance is changing from “passive maintenance” (driving until a problem occurs) to “active management” (scheduled replacement, condition-based monitoring). More and more car owners regularly replace engine oil, brake fluid, antifreeze, etc., paying attention to maintenance cycles and oil quality, reflecting the change from “car repair” to “car maintenance.” At the same time, oil consumption is also showing a trend of branding and specialization. Users’ requirements for quality, performance, and safety are constantly increasing. They no longer only focus on price, but tend to choose well-known brands, original factory standards, or vehicle-specific products, which puts higher demands on the company’s technical strength and brand trust. This trend benefits established brands with strong quality reputations (Liqui Moly, SONAX, 3M, WURTH GROUP).
2.2 New Energy Vehicles (NEVs) Reshape the Fluids Market
The rapid popularization of new energy vehicles (EVs, PHEVs) is reshaping the automotive fluids market. While demand for traditional engine oil has declined (EVs have no engine), demand for new oils such as motor coolant, reducer oil, and battery thermal management fluid is growing:
- EV-specific motor coolant – Must have low electrical conductivity (to prevent short circuits), good thermal transfer, and corrosion protection for aluminum/copper. Dielectric fluids or low-conductivity glycol-based coolants are replacing conventional engine coolant.
- Reducer oil – EV reduction gears require specialized lubricants (different from ATF).
- Battery thermal management fluid – Direct cooling systems (immersed cell cooling) require dielectric fluids.
This shift brings new technical challenges and market growth points to the industry, forcing traditional oil manufacturers to accelerate product transformation and upgrading. Liqui Moly and STOCKMEIER Group have launched EV-specific coolant lines (2025-2026).
2.3 Product + Service Integration (As-a-Service Models)
The integration of “product + service” has become a new direction for the industry’s development. Many companies have shifted from selling oil products to providing integrated services such as door-to-door maintenance, membership customization, and oil monitoring to improve user stickiness and form a differentiated competitive advantage. Service experience is gradually becoming an important factor for users when choosing brands. Examples:
- Mobile oil change services – Mobile vans equipped to perform oil changes, fluid checks, and top-ups at customer locations (home, office). WURTH GROUP and ALTRO GROUP have launched mobile maintenance services.
- Subscription-based maintenance – Monthly or annual fee covering all routine fluid maintenance (oil changes, coolant flushes, brake fluid replacement, washer fluid top-up).
- Connected vehicle fluid monitoring – IoT sensors (aftermarket or OEM-integrated) monitor oil level, quality, and remaining life; trigger service alerts and auto-order fluids.
2.4 Environmental Regulations Drive Green Formulations
Environmental protection laws and regulations are driving the industry to transform toward green and sustainable development. Low-volatility, low-pollution, recyclable environmentally friendly lubricants and antifreeze are gradually becoming the new favorites of the market. Green products and sustainable service models will occupy a more important position in the future oil market. Key regulatory drivers:
- EU – REACH regulations restricting hazardous substances; Euro 7 emissions standards (indirectly affecting engine oil formulation).
- US – EPA Safer Choice program for cleaning products (windshield washer fluid, degreasers); state-level VOC limits (California, New York).
- China – China VI emissions standards; “dual carbon” goals driving green product demand.
Manufacturers are launching bio-based lubricants (plant-derived base oils), non-toxic antifreeze (propylene glycol vs. traditional ethylene glycol), and concentrated (reduced packaging) washer fluid tablets.
Industry Layering Perspective: Fluid Type Characteristics
- Lubricating Oils – Highest value, most technically complex. Engine oil is the largest sub-segment (estimated 70-75% of lubricating oils). Synthetic oils (PAO, ester) growing share over conventional mineral oils. Replaced every 5,000-15,000 km (varies by vehicle and oil type).
- Cooling Oils – EV growth is key driver. Conventional engine coolant replaced every 2-5 years; EV coolant may have longer intervals but higher fluid volume per vehicle.
- Cleaning and Auxiliary Oils – Brake fluid (hygroscopic, absorbs moisture, degrades performance; replaced every 2-3 years). Windshield washer fluid (highest volume, lowest value, seasonal (freeze protection) variants).

4. Exclusive Expert Insights and Recent Developments (Q4 2025 – Q2 2026)
Insight #1 – EV Coolant Specifications Standardize
The EV industry has lacked standardized coolant specifications, leading to confusion and potential vehicle damage (using incorrect coolant conductivity). Over the past six months, industry bodies (ASTM, SAE) have accelerated development of EV coolant standards: ASTM D8022 (dielectric coolant), SAE J3223 (low-conductivity coolant). Liqui Moly and STOCKMEIER Group have launched products certified to emerging standards, gaining first-mover advantage. Standardization will accelerate EV coolant adoption.
Insight #2 – Mobile Maintenance Services Scale Up
Post-COVID, consumers value home-based services. Mobile oil change and fluid maintenance services (ex: WURTH GROUP’s “Würth on Wheels,” independent operators) have scaled rapidly. A mobile van equipped with fluid tanks, pumps, and diagnostic tools can service 8-12 vehicles/day, offering convenience at a 20-30% price premium over shop-based service. The mobile service model increases fluid consumption per vehicle (full-service fluid check and top-up vs. customer self-serve). This channel is growing at 15-20% CAGR, outpacing traditional DIY (do-it-yourself) and DIFM (do-it-for-me) channels.
Insight #3 – China’s Domestic Lubricant Brands Gain Share
China’s lubricant market has been dominated by international brands (Castrol, Shell, Mobil) and Chinese state-owned giants (Sinopec Great Wall, CNPC Kunlun). However, aftermarket-focused private Chinese brands (not listed in QYResearch top players) are gaining share in the maintenance fluid segment (brake fluid, coolant, washer fluid, specialty additives), offering lower prices (30-50% below international brands) and aggressive e-commerce distribution (Tmall, JD.com). International brands are responding with China-specific formulations and price adjustments.
Typical User Case (Q1 2026 – US Fleet Operator, 200 Light-Duty Trucks):
A US regional delivery fleet (200 Ford Transit vans) transitioned from shop-based maintenance to a mobile maintenance service (WURTH GROUP). The mobile van visits fleet depot monthly, performing oil changes (synthetic 5W-30), brake fluid moisture testing and replacement (as needed), coolant level check and top-up, and windshield washer fluid refill. Fleet results over 6 months: (1) vehicle downtime reduced by 40% (no trip to maintenance shop), (2) maintenance cost per vehicle reduced by 12% (reduced overhead), (3) fluid consumption increased (full service includes top-ups that drivers previously neglected). The fleet standardized on Liqui Moly engine oil (premium synthetic) to extend oil change intervals from 5,000 to 7,500 miles, reducing annual oil consumption by 25%.
5. Technical Challenges and Future Pathways
Despite growth, challenges persist for automobile maintenance fluids:
- Consumer education and compliance – Many car owners neglect fluid maintenance (brake fluid especially, as no immediate drivability symptoms). Industry must educate on safety consequences (brake fluid moisture reduces boiling point, can cause brake fade). Regulations mandating brake fluid testing during vehicle inspections could drive compliance but are not widespread.
- EV fluid specification complexity – EV manufacturers (Tesla, BYD, Volkswagen, GM) have proprietary coolant specifications, confusing aftermarket. Standardization efforts (ASTM, SAE) will reduce complexity but take time. Until then, aftermarket providers must stock multiple SKUs (stock keeping units).
- Counterfeit and low-quality products – Low-cost, substandard maintenance fluids (non-spec oils, watered-down coolant, methanol-based washer fluid) cause vehicle damage and safety risks. E-commerce marketplaces (Amazon, Alibaba) have counterfeit issues. Brand and channel verification (QR codes, holograms, authorized distributor programs) are essential for premium brands.
Future Direction: The automobile maintenance fluids market will continue its 7-8% CAGR through 2031, driven by: (1) growing vehicle parc (especially in emerging markets), (2) shift from passive to active maintenance, (3) NEV fluid demand (coolants, reducer oils), (4) product + service integration (subscription, mobile maintenance), (5) environmental regulations favoring green formulations. Key strategic imperatives for manufacturers: (1) invest in EV-specific fluid lines (dielectric coolants, reducer oils), (2) develop subscription and mobile maintenance partnerships, (3) differentiate via premium quality and brand trust (avoid commodity price competition), (4) ensure regulatory compliance (VOC limits, REACH, bio-based content). For vehicle owners, regular fluid maintenance is a low-cost investment in safety and longevity; for industry participants, the shift toward “active management” and service integration offers higher margins and customer lifetime value than traditional product-only models.
