I notice that a lot of you here like Mobil 1 oil. What about other brands of Synthetics like Castrol, Valvoline, Pennzoil, Exxon? I personally have a preference for Castrol, due to my early years spent on a motorcycle and relying on GTX. Also, I noticed at Autozone Exxon Synthetic for $3.19 a quart compared to $4.49 for Mobil 1. With Exxon and Mobil being one company, is there really any difference between the two other than labelling and price?
