Hi All,

Maybe a dumb question, but...

I've been used to adding additives (Millers, mainly) to my previous XF. My current XF needs AdBlu, is it OK, necessary, or desirable to continue adding the additives?

Cheers,
Jon 

My noddy understanding ad blue helps to remove more of the rubbish coming out your exhaust, it can also provide new messages on your dash, had a few issues with my XE. You always need ad blue in your car or it will stop when it runs out

The additives if you mean adding to your petrol clean your injectors etc and parts of your engine. I normally use premium shell fuel which has it added already, but would certainly reconmend adding in revex or something every other full tank etc.

Hi Jon

I was thinking about buying a diesel the other week and did a bit of looking into this Ad Blue, since I’d never used it before.

 As far as I can make out, Ad Blue is ONLY injected into your exhaust pipe (NOT your engine) and it is only used to convert the harmful nitrogen oxides in your exhaust gasses into cleaner, more breathable air (very similar to a catalytic converter in a petrol car).

As the Ad Blue is only there for one specific, narrow purpose and doesn’t go anywhere near your engine, I would think that any additives you put in your fuel tank or engine oil should be fine and not conflict with it in any way 😊

I hope that’s helpful, but please do your own research on the internet or ask your Jag specialist, coz there’s lots of useful info out there.

(Just so you know, I didn’t buy the diesel in the end, so haven’t tried it myself!)

Happy motoring!

Thank you, Simon & Darren,

That all makes sense now. Sorry for the slow reply - just back from holiday!

From what I understand adblue must be used to comply with Euro 5
