29$ for 5ltrs of fully synthetic oil. Bargain. Used it for an oil change on my 2001 non turbo Subaru Liberty. No problems so far and not expecting any.

Brought this oil last oil change for my Subaru, done about 3000kms, oil level still up to the top mark and performs just as good as other oils. Overall, I'm happy with it. Will buy again at SCA.

I'm impressed with this oil and have been using it now for a while . It does a great job ,doesn't sludge and keeps my engine clean.
Supercheap website suggested this as an alternative oil, and it's a great product. Car loves it.
I am very pleased with this oil. It is fully synthetic and long-lasting, meaning I will be able to keep running without having to change the oil as often. It was also on sale, making it even more attractive.
GW performs just like an oil slick should do!1/2 The price same lube.
This is the second time using this oil in my CRV. Good value on special. Synthetic 5W30 A3B4 is a high quality versatile lube for many modern engines and suits our climate. Suitable for small engines too.
I buy this product because it is a 100% Australian owned company. The oil is formulated to meet the highest European standards. Also it generally sells for a lower price than the more established "Name Brand" products. Buy Australian!
Decent oil at a good price, happy with the purchase.
