alright guys, i have an 03 tacoma double cab, trd package, v6. looking to change oil when i hit 1000 ( which is real soon so quick replies would be greatly appreciated) which oil would you recommend, have always used castrol syntec blend, but am looking into full synthetic, is mobil or castrol better?? also, i have always used a k&n oil filter, should i stay with this practice or go with another brand?

 

Do a search for "synthetic", "amsoil", "mobil 1", "royal purple" and "redline" and you will find lots and lots of info and opinions.
