If you can't find it anywhere up there, give me a yell and I'll post some up to you. I'm a Gulf Western distributor but I sell Sougi at close to cost price for enthusiasts because I'm a good guy and I write it off as a marketing exercise lol. Don't gauge it by the cheapo mineral 20w50 that Autobarn like to loss lead for $10 a bottle - that stuff is designed for running in engines / oil flushing and servvicing pre-90's shitheaps that burn through oil, just like every other 20w50 mineral on the market.
Where can we find you in Victoria to get our hands on some 10W 40?
Also, does using an ethanol based fuel seem to make much difference to oil thinning in your experience?
cheers,
