As Kieran said above Opie oils. I spoke to Tim from Opie and l followed his recommendations. You can ring them and give them your model and spec and they will advice. Also they have set prices on postage based on weight so you can stock up within the weight limits
Ah Jesus should have said first about the airfreshener, ordered of them there on eBay same price and I don't have to go filling out anything, cheers [emoji106]
