Although I bought this stuff a month ago when it was on special and only recently changed the oil. I saw it again on special today at Tuggeranong Repco and bought another 5litres for when I do my next oil change. I've anecdotally noticed about 30-40km further per tank on this stuff, engine also seems to rev to redline smoother as well.
Went to my local Repco at 9.30this morning all 5W30 sold.
Interesting. Here in Vic, I went at 11am and most stores still had a lot of 5w30 left, but next to no stores had 5w40 (according to the guy on the computer). So I ended up grabbing 3x 5w30 and 2x 10w40 Valvoline Engine Armour which were $20 each. From memory though, Edge 5W30 is full synthetic where as 5W40 is semi synthetic. I could be wrong though, but at the same price, I would prefer a full synthetic oil anyways. I needed a 40w for my mum's 99 Vienta V6, even though Castrol's lube guide recommends Edge 5W30, I think it's a bit thin for an engine of that age.
Edit: It seems like the 5W30 is A3/B4 rated and 5W40 is SN rated. Not on the same scale so I'm not sure how they compare.
