Full details
This guide is for owners of modern petrol and diesel vehicles, particularly those with exhaust after-treatment systems like DPFs and AdBlue. The Morris Multivis ADT C3 5W-30 engine oil offers enhanced engine efficiency and protection, especially during cold starts. A key caveat is ensuring your vehicle's manufacturer specifications precisely match the ACEA C3, C2, MB 229.31, MB229.51, PSA B71 2290 (2014), API SN, or dexos2+ requirements before use. Its advanced synthetic technology provides superior wear reduction and improved fuel economy.

FAQs
What does 'mid-SAPS' mean for this oil?
'Mid-SAPS' refers to the oil having moderate levels of Sulphated Ash, Phosphorus, and Sulphur. This formulation is crucial for protecting modern exhaust after-treatment devices like Diesel Particulate Filters (DPFs) and catalytic converters, preventing premature clogging and damage.
Can I use this oil in my older petrol car?
This oil is designed for the latest petrol and diesel engines requiring a low viscosity (5W-30) and specific performance standards (ACEA C3, C2, API SN, dexos2+, MB 229.31/51, PSA B71 2290). If your older vehicle requires a different viscosity grade (e.g., 10W-40) or lacks after-treatment systems, it might not be suitable. Always check your owner's manual for the manufacturer's recommended specification.
How often should I change this engine oil?
The oil change interval depends on your vehicle manufacturer's recommendations, driving conditions, and the specific oil life monitoring system in your car. Consult your vehicle's owner's manual for the recommended service schedule. Typically, for modern vehicles using synthetic oil, intervals can range from 10,000 to 15,000 miles or annually, whichever comes first.
Is this oil suitable for turbocharged engines?
Yes, this fully synthetic 5W-30 oil is highly suitable for turbocharged engines. Its advanced additive technology provides excellent thermal stability and protection against wear, which are critical for high-performance, high-temperature environments like those found in turbocharged units.
What is the key benefit of the 5W-30 viscosity?
The '5W' (Winter) rating indicates excellent low-temperature fluidity, meaning the oil flows quickly when the engine is cold. This rapid flow to vital engine parts upon startup significantly reduces wear. The '30' rating indicates the viscosity at operating temperature, contributing to fuel efficiency.
My car uses AdBlue. Is this oil compatible?
Yes, this oil is developed for use in engines using exhaust after-treatment devices, including AdBlue systems. Its formulation supports the efficient operation of these systems.
What does MB-Approval 229.66 mean?
MB-Approval 229.66 is a specific performance standard set by Mercedes-Benz for engine oils. It indicates that this Morris Lubricants oil has met Mercedes-Benz's stringent requirements for performance, durability, and compatibility with their engines, particularly those with advanced emission control systems.
Troubleshooting
Engine oil light stays on after starting
Check the oil level immediately. If low, top up with the correct grade of oil. If the level is correct, the issue may be with the oil pressure sensor or pump, requiring professional inspection.
Increased engine noise, especially on startup
This could indicate insufficient oil flow or film strength. Ensure the correct 5W-30 viscosity and specification (ACEA C3, dexos2+ etc.) are being used. Check for oil leaks or a faulty oil filter.
Vehicle shows signs of poor fuel economy
While this oil is designed to improve fuel economy, other factors can influence it. Ensure the oil level is correct and that no other engine maintenance is due. Consult a mechanic if issues persist.
Check engine light related to emissions system
Ensure the oil used is compatible with your vehicle's emission control systems (mid-SAPS formulation for DPFs). If the wrong oil was used previously, or if the DPF is already compromised, professional diagnosis may be required.

Setup, Compatibility & Care
Compatibility:
This oil is specifically designed for petrol and diesel engines in cars and vans that require a 5W-30 viscosity oil meeting one or more of the following specifications: ACEA C3, ACEA C2, MB 229.31, MB229.51, PSA B71 2290 (2014), API SN, dexos2+. It is also suitable for hybrid electric vehicles. Always consult your vehicle's owner's manual to confirm the correct oil specification before use. Using the incorrect oil can lead to engine damage and void warranties.
Setup (Oil Change):
- Ensure the engine is warm but not hot.
- Safely raise and support the vehicle.
- Locate and remove the sump drain plug.
- Drain the old oil into a suitable container.
- Replace the drain plug with a new washer.
- Remove the old oil filter.
- Lubricate the rubber seal on the new oil filter with fresh oil and screw it into place hand-tight plus a further 3/4 turn (refer to filter manufacturer instructions).
- Lower the vehicle.
- Using a funnel, fill the engine with the correct amount of Multivis ADT C3 5W-30 oil, referring to your owner's manual for capacity.
- Start the engine and check for leaks. Allow the engine to run for a few minutes, then switch off and wait for the oil to settle. Check the oil level on the dipstick and top up if necessary.
Care:
- Store the oil container in a clean, dry, upright position away from direct sunlight and extreme temperatures.
- Dispose of used oil responsibly according to local regulations.
