Me too. It should then be good for up to 4 years.

Red OAT is best

Depends on how often you'll be changing it.

There is no difference between the OAT and the standard blue stuff in terms of its anti-freeze properties. The only difference is in the corrosion inhibitors. The blue stuff lasts 2 years, the red / pink / orange stuff lasts 4 or 5 depending on the type. Personally I use the blue.

So blue is fine to use in the K serise ?

I was told to use the OAT red one as it can cause hgf.

ill use the blue then as its easyer to get my hands on.

I wondered about HGF using blue? I think a full flush then red is the way to go - many thanks for your help!

As you don't try to mix the OAT, HOAT or conventional types you should be fine with any of them.

I got red in mine to guys......

Doesn't matter what the colour is, it'll not make it any more/less prone to HGF.

Both are ethylene glycol, just the Red/Pink/Orange stuff has different additives to prevent corrosion.

I used blue in our old 1.4 for 60k miles without issue.
