Hi,
Past owner was using synthetic but I don't know what grade. I was looking for 15W-40 as going by my manual it looks best for the temperature range here in Canada. I could only find 15W in a conventional Diesel oil. I bought 1 liter of Castrol Syntec 5W-40 for topping up but what should I use for my next oil change? I also saw synthetic in 10W-30, 5W-30, and 5W-50.
