G'day all 

So I'm sure you're all familiar with the red coloured K&N air filter oil. I'm also sure some of you would have seen that some people are rocking blue air filter oil, which is not made by K&N I believe.

I can find several different brands of the stuff and I have no idea if any of it is any good. I've always used K&N filters, their oil and cleaning kits. My question is do any of you use an alternative air cleaner oil, the blue stuff specifically, and are there any brands I should try or avoid?

Why use something other than the K&N oil? (I have one of their kits that has the cleaner and oil in it and love it...use it about once every six weeks but do suck a LOT of air...lol)
They are market leaders and know their chit so just stick with the best - and do not stress it too much, as its ONLY thin oil after all!

Just curious and getting a bit bored of the red but the more I look around the more I'm beginning to think that the blue filters I've seen have actually been blue filters and not ones with blue oil.
