Full details
Designed for drivers looking to maximize engine longevity and performance, this Liqui Moly bundle is ideal for owners of modern gasoline and diesel vehicles, including those with turbochargers. The combination of high-tech 5W-40 motor oil and a concentrated engine flush additive works to remove sludge and reduce internal friction, resulting in better fuel economy and smoother operation. While highly effective, users must ensure their vehicle manufacturer specifically recommends the 5W-40 viscosity grade and meets the listed industry specifications to avoid voiding engine warranties.

FAQs
Can I use this in a diesel engine?
Yes, this oil is specifically formulated to meet ACEA B4 requirements, making it compatible with many modern diesel engines.
Is the engine flush safe for my engine seals?
Yes, the Liqui Moly engine flush is formulated to be gentle on rubber seals and gaskets while effectively removing oil-based sludge.
How often should I use the engine flush?
It is recommended to use the engine flush during every oil change to maintain internal cleanliness.
What if my car requires 5W-30 instead of 5W-40?
You should use the viscosity grade recommended by your vehicle manufacturer. Using 5W-40 when 5W-30 is required may affect engine efficiency.
Does the Molygen oil really look different?
Yes, Molygen oil has a distinct greenish fluorescent color due to the special additive package used in its production.

Oil pressure warning light stays on after change
Verify that the correct amount of oil was added and that the oil filter is properly seated and tightened.
