Oil grade/spec!
Hi all. I changed the oil and filters on my car last week using Castrol Edge 5w30. It's the third time since I've bought the car, as I change the oil and filter every 6-7 k. This time though, the oil temp sits around 103c-107c (mway) compared to around 95c previously. Yesterday doing 60 mph (mway for about 15 miles) it was around 98-100c with an outside temp of 4c. Even in the summer (doing 80-90mph in Europe) with an outside temp of 38c, the oil temp was around 100c. Why is this happening? Also, I can get some Castrol Edge 5w40 or 0w30 for a very good price. I know neither of them is a 507 oil, but can I use either of those if I change the oil at 5k? Thanx for any input.
