Not too sure if this has been posted but im pretty sure most will already know about this, but Euro Car Parts currently have a online offer where if u use the code PARTS25 knocks off 25% of most things, Notably Oil for me...

Can get a 4L bottle of Castrol Edge 5W30 Oil for £28.90 using the code, which is a bargain, Next cheapest (that i know of anyways) is in Asda selling for £35.

If your close to a Eurocarparts, its better just to do the Click and Collect too, pay instore and get your goods at the counter

As i said this info may be completly useless but i thought id post it anyhoo for people out there!
