Your oil of choice...

Been using Castrol for years,it's served me well.I've had many high mileage vehicles over the years,as soon as I get 'em I do an oil change and put Castrol in I've yet to have an engine failure.

I've used Royal Purple the last few times, mainly because I bought a case and wanted to use it all.

I am thinking of going Amsoil next time around. I really don't quite put enough miles on to justify synthetic though.

Mobile 1 full synthetic, baby. Although I have royal purple in right now cuz it was on special. It's also a good brand. I use it in the diffs too.
