Purpose and Specifications

The ALCO FILTER PRIMUS FOS 5W30 1L is a budget-friendly engine oil designed for smooth performance in Ford, Renault, Jaguar, and Land Rover vehicles. Its 5W30 viscosity flows easily at cold starts down to -30°C and stays thick up to 150°C, reducing wear during extreme temperature swings. Meeting specs like API SL, ACEA A5/B5, FORD WSS-M2C913C/D/B, RENAULT RN0700, and JAGUAR LAND ROVER STJLR.03.5003, it provides reliable protection for gasoline engines, keeping parts clean and minimizing friction for longer engine life.

Practical benefits include better fuel efficiency from low-drag flow and strong film strength that cuts metal-on-metal contact, ideal for daily drivers and light towing.

When to Use / Replace?

Use this oil in compatible Ford, Renault, Jaguar, and Land Rover models for everyday driving. Replace every 6,000-6,500 km (about 3-4 months) under normal conditions like highway miles, or sooner at 5,000-5,500 km for city stop-go traffic, short trips under 10 km, dusty roads, or towing. Shelf life is 3-5 years unopened in cool, dry storage.

• Normal driving (highway, moderate temps): Change at 6,500 km or 4 months
• Severe use (short trips, extreme heat/cold): Change at 5,000 km or 3 months
• Always check dipstick; top up if low (normal use: under 1L per 1,600 km)

FAQ

Q: Is 6,500 km too short for synthetic 5W30?
A: No, lab tests on 5W30 synthetics show peak protection to 6,500 km before acids build up and viscosity drops, preventing engine damage vs. risky 10,000+ km stretches.

Q: Can I use this in hot climates?
A: Yes, it holds up to 150°C operating temps, perfect for summer heat without thinning out.

Q: What's the 1L pack for?
A: Great for top-ups between full changes or small engines; keeps you running without waste.
