ok you can buy 5 Litres for £12 or you can buy 6 Litres for £9 + they are individual cans so easier to store! It can be a pain in the butt having to buy 5 Ltrs when you only need a little top up
This is asda own brand only.
No idea how long this offer is on and its only the diesel oil that has the tags, im not sure if the regular oil is included in the offer.
Im also guessing this is instore only though i havnt checked the web site.
