You're most welcome MF
I would normally suggest waiting until 25/10 for the likely $10 Autobarn special, however the $3 would probably be eroded in time, petrol and car wear and tear to get to an autobarn as I know you don't have one near you.
If you want to go for a bottle of SAE30 as well you could get this
https://www.repco.com.au/en/oils-fl...w-mono-engine-oil-1l-1281-01/p/A9633836. Rare to get SAE30 cheaper that $5 per L. Its marginally cheaper per L than the 5l Repco brand SAE30 on special this week.
Was lucky enough to pick up a (very short lived) price error a few months ago at SCA whereby I got 24x 1L bottles of SAE30 for $27, but that will never happen again unfortunately.
I still use 15w40 in everything, I note no difference in the 1x quantum and 1x classic 35 I am running on SAE30, but it is an ongoing test
