What time frame is recommended adding to car prior to oil change?. Car is scheduled for change in the morning. Thank you

This product is to be added right before the oil change, then the car should be idled for about 10 minutes. The vehicle should not be driven withengine-flush in the engine.

I understand this product does not qualify for the warranty replacement but If this is added to the engine, once flushed can the oil still be returned under the warranty?

The oil can still be returned under the LRG.

Does this part qualify for lifetime warranty replacement?

Unfortunately, this wouldn't technically qualify because our warranty requires you to return the product. Once used, there's no way to actually return just the engine flush.

My oil level is at MAX, do I need to take some oil out first before putting liqui moly? I have N51 engine, about 6.5 quarts; would 1 can suffice? Thank you.

No, you won't have to remove any oil. One 500 ml can is sufficient for up to 5 litres of oil. ideally, you'll want to use part of a 2nd can since your car takes more than 5 liters. Add Pro-Line Engine Flush to the engine oil at running temperature before changing the oil. After adding the product, allow the engine to idle for approx. 10 to 15 minutes depending on the degree of contamination. Then change the oil and the filter.

Can you add it to your oil immediately or should you let car get to temp then add this product? I understand letting it run for 10 mins on idle, just confused on if it has to be operating temp before you add?

You can add while the engine is cold, then start the engine and let it idle for 10 - 15 mins. Then turn off the engine and drain oil.

I noticed it says a 500ml can will treat up to 5L of oil. I've got a 2016 GTI and the fill is 5.7L. Would this require the use of some additional flush or is the 500ml can sufficient?

It would be recommended to use part of a 2nd can to match the 5.7 liter fill quantity. The use of 1 can would be ok as well.

Can I use this for old Japanese car, like 1987 MR2? And 2014 Ford transit connect?

Yes.

Does this oil flush remove or change the properties or coating from the liqui Moly Cera tec engine coat?

No. This flush product is comprised of the same cleaners and dispersants found in Liqui Moly engine oil.

Is this safe to use on cars with VVT?

Yes.

Can I use engine oil extractor after using this engine flush to change engine oil? Thank you.

I recommend draining from the oil pan, that will be better at removing the old oil and flush from the pan.
