What brand oil do you use?

What brand oil do you use when you change your oil? What weight do you use and why? What brand won’t you use?

I use 10/30 during the summer and 10/40 during the Winter. I use the High mileage oil from Castrol. I change my oil every 5000 miles.

Mobile One 0W-30 synthetic. The car is under warranty so I change it every six months (around 5,000 miles). I don’t know if it really makes a difference, but the engine sounds a lot smoother. sunny.gif

I always use NAPA.

I tried synthetic once. The engine started a LOT easier in the
winter, but the cost is too high to justify using it all year.

In my cars I use Castrol, except for the Tbird which has Rotella in it.
