Thanks Chris and will do, I take it that doesn't affect warranty in any way if I purchase my own oil and top up then rather than have dealer do it?
Hi, you'd be wasting your money that, as Nathan_MAZDA2 says they'd never know and we all do it anyway..
Chris
Get your oil from your local Camberly Auto Factors as its a lot cheaper than Halfords.

I bought a 5 litre bottle DriveTec 5w30 fully synthetic (suitable for Petrol engines and Diesel engines) for just £25.63...The cheapest equivalent 5 litre bottle of oil at Halfords is £38.99!
