## Questions & Answers

**Q: Can i use this in my motorbike that has a wet clutch ?**
A: hi this product thickens engine oil would say it would be too thick to use in a wet clutch I use it in an old car with a worn engine think that is what it does best

**Q: Is good for a6 2009 tdi 2.0l ? Automatic?**
A: I have a 2010 VW 2.00 litre auto and works fine on mine.

**Q: When using this product. Do you need to pour the entire bottle to the engine or half etc?**
A: Hello, First of all run a hot bowl of water and stick the bottle in and leave it for 10 minutes,reason for this its as like a set honey. In answer to your question you use the whole bottle at once preferably in a warmed up engine. Simply poor in where you top up oil and start the engine to allow it to idle for around 5 minutes this will allow it to mix with your oil properly whilst the engine is under minimal load.  It's a great product , hope this helps

**Q: Can I use this on a Diesel engine with a dpf**
A: Yes you can - Has no direct influence on DPF performance. Need a fuel additive for that.
