I started using Castrol years ago because the local auto supply carried it. It was difficult to impossible finding the more exotic racing oils suggested by the OEM’s. I decided to try an online order and that makes it even more convenient. I’ve had really good results with Castrol. It doesn’t cloud up the sight glass like some other brands. The large opening makes for quick pours. I recommend Castrol to everyone who asks. The price is around middle of the pack, not cheap, not ridiculous. It’s good oil. Try it!
