Gulf Western XP Engine Oil 20W-50 4 Litre - normally $19.99 - now $13.99 at Supercheapauto. Free Click and collect or delivery available.
Delivery worked out to only be $5 - am in Sydney (your mileage may vary) so picked up 3 to be delivered and not not have to worry about oil for a while…..
yes quality wise probably not the best but the car its going in is about as good as the oil is.
Listed on Ebay as well if you want to use coupons/other payment methods/giftcards etc
