FAQs
Can I use this in a car with a DPF?
No. This oil is not suitable for vehicles equipped with Diesel Particulate Filters or other exhaust aftertreatment devices.
What does the 5W-40 rating mean?
It indicates the oil's viscosity. '5W' represents its flow performance in cold temperatures, and '40' represents its thickness at operating temperatures.
Is this oil compatible with synthetic blends?
Yes, but mixing synthetic and conventional oil is generally discouraged as it will dilute the high-performance benefits of the full synthetic formula.
How often should I change this oil?
Follow the oil change intervals recommended by your vehicle manufacturer, or based on the oil life monitoring system.
Does this meet Mercedes-Benz requirements?
Yes, it carries MB 229.3 approval, making it suitable for specified Mercedes-Benz engines.
Troubleshooting
Oil pressure warning light remains on after change
Check oil level with dipstick and ensure the correct oil filter was installed securely.
Engine feels noisier after oil change
Verify that you have used the correct viscosity grade for your specific engine and confirmed the oil level is correct.
Oil appears dark shortly after an oil change
This is normal, as the detergents in the oil are actively suspending existing soot and deposits to keep them away from engine surfaces.

Setup, Compatibility & Care
Before using this oil, verify that your vehicle manual does not require a low-SAPS or 'C' grade oil, as this R-Tec 28 formula is intended for engines without aftertreatment devices. To perform an oil change, consult your service manual for the correct oil capacity and drain plug torque specifications. Always dispose of used engine oil and filters at a certified local recycling facility. Store the oil in a cool, dry place, ensuring the cap is tightly sealed after each use to prevent oxidation and moisture contamination.
