Thanks for posting this! It's definitely good to finally see some specs on this oil! The 0w40 definitely looks like a decent oil, this is the oil my friend sells at his speed shop in Woodbridge, and he really wanted me to try this oil in my car and do oil analysis on it. But even though he was going to sell me the oil at his cost, it would've been $11.50 per liter, almost double what I pay for GC 0w30. So which of these oils will you be trying out?
