Dear Scotty,

I have a question with I have been running around with for ages. I wonder if it is important to buy expensive, well-known brands of oil instead of the cheap brands of oil. I know that the oil type is very important. You have to get the right one thickness, for example 10w5 and whether it is synthetic or not. But does it matter whether I buy expensive Castrol or cheap unknown brand of (engine) oil?

all oils are made in the US to certain standards and are fine. But higher quality oils like castrol do last longer and lube better due to higher additive
