Hi I should have asked before I purchased 24 litres hahah, but just checking that 5w30 redline synthetic should be okay for use in new Euro for changes between dealer services?

It works out $11-12 per quart shipped to AUS from amazon at the moment when you buy 12 quarts, seems very cheap compared to $20-$30 prices in Australia.

Apparently its quite thick and more like 5w-38, I am in Brisbane so just wondering if this grade will be okay in the heat?

Any input welcome.
