Brand new fuchs and castrol oil

Guys I am selling or swapping these two oils, both as you can see are un opened and purchased 4l for the front diff and box and the castrol for the rear diff. Both purchased from opie oils and cost me around £50

I am after a fully synthetic 5-30 if anybody has one and want to do a deal or after around £35. Collection preferred ( cardiff ) but I can post but I don't see you making a saving if you have to pay carriage
