With adblue it’s not the engine that determines how much Adblue will be used it’s your style of driving, if you are doing lots of short trips where the engine and more importantly the cat and DPF doesn’t get hot enough then you will use more Adblue.
look out for Adblue at Aldi at £16.99 its gone up from £11.99 6 months ago but still cheaper than garage. I decant the 10ltr into a jug for filling the tank.
I use the 3.5ltr pouches from Halfords, easy to handle for top ups.
3 x 3.5ltr pouches for £20.
