will this work with a 2017 Jetta GLI with 6spd DSG?

Yes, it will.

Saw on the label it is not suitable for automatic engines. Would it be okay to use in a 2010 a4 automatic engine? not seeing anything on the site about it but on the bottle it says so

This is certainly suitable for engines with automatic transmissions.

Is there a certain break-in period to allow the ceramic particles to bond. Or can i go WOT from the start?

There is no break in period.

Is this Wet clutch compatible? i’m wanting to run it in my 03 Cbr600rr

No, it is not.

Can I use this product after doing an oil change and filling my N20 with 5W-30 Liqui Moly engine oil from the oil change kit sold here?

Yes, you can, the amount of Ceratec added would displace the respective oil amount so as to not overfill.

Does it work on my F30?(with 8hp45 transmission) I am planning to add this into the engine oil, but not the transmission fluid

Yes, to be used as an engine additive only.

When buying a second time on this site how to quality for the lifetime warranty? Can I pour oil in this and send back?

This is not covered by our lifetime warranty. This is outlined in our policy for exceptions which states the following: "The only exclusion to this program is empty containers with contents that can not be physically returned." Since this additive adheres to the internals of your engine and dissipates over time you cannot return the product purchased from us.

Hi. How many bottles do I need for 2011 X5M which uses about 9.4 quarts per oil change? thanks.

You'll need to use slightly less than 2 cans.

If my car already has the recommended 6 quarts (5.7 liters) of oil after a recent oil change, will adding this 300ml bottle to the full oil level cause any harm or issues of overfilling?

No. You will be fine. The carrier for the additive is a mineral oil that burns off anyway. This product ultimately does not displace any volume.

Can I mix CERA TEC with Leichtlauf High Tech motor oil for my next oil change?

Yes.
