Yup that's right. Before joining the community I've always used 10w-40 oil in my cars. I use Castrol Magntetic 10w-40 in my tb.
Through my reading it says I should be using 5w-30 or 10w-30 If the first isn't available.
My engine runs smooth and been using this oil for the past 2 years with 189,000km now.
I'm gonna go with the right oil 5w-30 in my next oil change. I know this oil is better in cold climates but what about extreme heat?
Could I have potentially harmed my engine using 10w-40?
