Prince Lubricants has proudly participated in a wide range of prestigious motorsport events, including FIA Formula series, GP3, GT World Challenge, GT Asia Challenge, Le Mans Endurance, Nürburgring Endurance, King of Europe Pro Drifting, and the African East Safari Rally. We’ve also supported over a hundred Touring Car Racing (TCR) events globally, proving our oils and fluids in the most demanding racing environments.

Our advanced formulations are built on a foundation of high-quality base oils mainly Group III, and fully synthetic Group IV (PAO) and Group V (Ester) where performance demands it. We work with recognized major additive suppliers such as Infineum, Afton, and Lubrizol ensuring our products meet the latest OEM performance standards.

P-9 Ester and P-12 Ester found in our signature passenger car motor oils and truck diesel engine oils blend optimize lubrication stability, volatility control, reduce oxidation, and ensure prolonged oil and engine life in extreme operating environments and temperatures.

Yes, many of our fully synthetic and synthetic engine oils are formulated with reduced SAPS (sulfated ash, phosphorus, and sulfur) eco-conscious technology, making them absolutely compatible with the Euro 6 diesel and gasoline engines. They are specifically designed to protect emission reduction systems, including particulate filters and catalytic converters, while maintaining top-tier engine functionality and performance.

Yes, we offer exclusive distribution rights on a per-country basis. Once appointed, you will be the sole authorized importer and distributor in your country, with full rights to market, sell, and grow the brand locally. We do not appoint multiple distributors in the same territory, ensuring clear protection and sustainable partnership. We can explore opportunities!

Yes, we do set annual sales targets as part of our sole distribution agreements. These targets are carefully tailored based on your market’s population, vehicle data, and growth potential. They help ensure mutual commitment and excellent brand development, while protecting your exclusivity within the agreed territory/ country.

Certainly, we provide marketing support to our distributors. This includes digital promotional materials, product brochures, social media content, and guidance on brand positioning. We also run online ad campaigns in selected markets and pass all generated leads directly to our local partners to boost sales and visibility.

Yes, we are open to collaborating on the development of new formulations tailored to specific market segments. Whether it’s for climate conditions, fuel types, industry-specific applications, or performance preferences, our team can work closely with you to develop products that meet your market’s exact demands and requirements — while maintaining compliance with international standards and rigid performance benchmarks.

Our flagship product series includes FSR, FS1, and D1 — each representing the pinnacle of our formulation expertise and ester innovation.

FSR is a PAO and ester-based series, tested and refined for over a decade through intense and demanding motorsport applications.

FS1 is our premium P-9 ester-based motor oil, engineered for everyday passenger cars and sports cars, offering maximum engine cleanliness, responsiveness, and protection.

D1 GOLD and D1 GOLD 4x4 are designed for on-highway and off-highway light and heavy-duty trucks and pickups, meeting the demands of the latest diesel engine technologies with high load tolerance and extreme heat stability.

While these are our most notable lines, the entire Prince Lubricants portfolio is developed to deliver optimal quality and performance across all applications and sectors.

The ideal oil type depends on your vehicle’s make, model, and the OEM’s specifications. Always refer to the manufacturer’s recommendations before selecting a high-performance Prince Lubricants motor oil for optimal protection and performance.

A full-service oil change includes up to 8 liters of engine oil, a new oil filter, and lubrication of chassis components as per your vehicle manufacturer’s specifications. We also recommend checking your transmission fluid, power steering fluid, brake fluid, antifreeze coolant, washer fluid, as well as inspecting tire condition and wiper blades to ensure your safety and optimal vehicle’s performance.

Yes, Prince Lubricants products are compatible with most commercially available engine oils that meet similar industry standards. However, for optimal performance and to maintain engine integrity, we always recommend using the same formulation type throughout each oil change cycle.

Yes, if your owner's manual specified SAE 0W-20, then that is the correct viscosity grade for your vehicle. This viscosity is designed to provide optimal engine protection, fuel efficiency, emission reduction, and cold-start performance especially in modern gasoline engines built for energy-conserving and low-viscosity oils. We recommend choosing a fully synthetic 0W-20 oil, such as Prince Lubricants FSe ILSAC GF-6A or FS SUPER ILSAC GF-5 series, for the highest performance and long-term engine protection.

Yes, you can top up with a different motor oil brand or type as long as both oils meet the same viscosity grade (e.g. SAE 0W-30) and industry standards (such as API or ILSAC). However, for optimal performance and engine protection, it's best to use the same brand and formulation type consistently. Mixing different oils occasionally is generally safe, but avoid prolonged use of mismatched formulations — especially when combining synthetic and conventional oils.

Motor oil should typically be changed every 5,000 to 15,000 kilometers (3,000 to 9,000 miles), or every 6 to 12 months — whichever comes first. However, the exact interval depends on several factors:

1. Manufacturer's recommendation (always follow the owner's manual handbook)
2. Oil type (fully synthetic oils last longer than semi-synthetic or conventional)
3. Driving conditions (frequent stop-and-go traffic, towing, or extreme temperatures may require more frequent changes)

For vehicles using high-quality synthetic oils, some engines may allow intervals up to 20,000 km (12,000 miles) under normal operating conditions. However, always check your oil level and appearance regularly, and follow the maintenance schedule for optimal engine health.

ATF should typically be replaced every 30,000 to 80,000 kilometers (17,000 to 50,000 miles), depending on fluid type, vehicle and driving conditions.

Severe use — such as towing, heavy traffic, or high temperatures may require more frequent changes. Always refer to your manufacturer’s guidelines to ensure optimal transmission efficiency and durability.

For vehicles with longer replacement intervals, we recommend using 100% synthetic or synthetic-blend oil formulations — such as those offered by Prince Lubricants for enhanced oxidation resistance and fluid stability.

Brake fluid is a vital yet often overlooked fluid during regular maintenance but it's critical to your safety. It’s generally recommended to replace brake fluid every 2 years, or every 40,000 kilometers (25,000 miles), depending on your vehicle manufacturer’s recommendations. Over time, brake fluid absorbs moisture, which can lead to reduced braking performance, corrosion in the braking system, and increased risk of failure, especially under high-stress or emergency conditions. Regular replacement ensures responsive, reliable braking when it matters most.

Unopened motor oils typically have a shelf life of 5 years when stored properly in a cool, dry place away from direct sunlight.
