Purpose and Specifications

Comma Eurolite 10W-40 is a semi-synthetic engine oil designed for both petrol and diesel vehicles with fuel-injected and multi-valve engines. This oil provides high-performance protection while maintaining affordability, making it suitable for everyday driving in European vehicles.

The 10W-40 viscosity rating means the oil flows easily in cold weather (down to -39°C) while maintaining protective thickness at normal engine operating temperatures (around 100°C). This balance helps your engine start smoothly in winter and stay protected during summer driving.

• Approved for major European standards: VW 501.01, VW 505.00, Mercedes-Benz 229.3, PSA B71 2300, and ACEA A3/B4
• API SN CF rated – meets modern emission and performance requirements
• Contains protective additives that clean engine deposits and reduce acid buildup
• Shelf life: 5 years from manufacture date

When to Use / Replace?

Use Comma Eurolite 10W-40 if your vehicle manufacturer recommends a 10W-40 semi-synthetic oil. Check your owner's manual to confirm compatibility with your specific model.

Oil change intervals: For semi-synthetic oils like this, plan oil changes every 6,000 to 10,000 km or every 6 months, whichever comes first. If you do mostly short trips or city driving, change it more frequently (closer to 6,000 km). Highway driving allows longer intervals.

Operating temperature range: Safe for use from -39°C to +230°C, covering all normal driving conditions in temperate and cold climates.

Frequently Asked Questions

Q: Is this oil suitable for my older diesel car?
A: Yes. Comma Eurolite 10W-40 is approved for both petrol and diesel engines, including older fuel-injected models. Always verify your vehicle's manual recommends 10W-40 viscosity.

Q: How does semi-synthetic compare to fully synthetic?
A: Semi-synthetic offers good protection at a lower price than fully synthetic. It provides better performance than mineral oil but doesn't last quite as long between changes. For budget-conscious owners, it's a solid middle ground.

Q: Can I use this in modern engines?
A: Modern engines often benefit from lower viscosity oils (like 5W-30) for better fuel economy. Check your manufacturer's recommendation first. If your manual specifies 10W-40, this oil works well; if it recommends 5W-30, use that instead for optimal efficiency.
