Super Cheap Auto did this oil for $30 twice last year, which is the best price you can get. It is always $52-$55.
This is fully synthetic, if you want "true" fully synthetic you pay a bit more for Mobil 1, usually $60-$95.
Repco have this for $43 with bonus free Octane boost but they wouldn't live up to their "beat price" policy, so I went with giving SCA the business for offering the lowest price.
I'm sure Big W and Kmart will match the price. Even when Kmart have 25% off oils now & again, it would still be $40.
There are other good deals in the catalogue.
The other viscosity levels in the Sport Edge range are:
0w-40 $59, 10w-60 $59, 25w-50 $29.48
"This is fully synthetic, if you want “true” fully synthetic you pay a bit more for Mobil 1, usually $60-$95."
True meaning what? It's either fully synthetic or not!
Btw, I've been using this 5w30 oil in my Honda Jazz since new. Great oil. Engine is still revvy when the oil has warmed up.
