Hey was just wondering what you guys think about for my next oil change. I hear a lot of people (that spoil their car to the max and treat it extremely well) use Royal Purple during the winter and Castro during the summer.

Synthetic oil is synthetic oil but still, lol i need an oil change and dont know what i should go with, maybe even mobil 1?!

 

im using Castrol EDGE 10w30, it comes in the 5 qt jugs which is convenient..

If it gets really cold by you in the winter, switch to 5w30 or German Castrol 0w30 AKA Castrol SYNTEC 0W

 

RP all year round...,

Neither, Mobil1 year round.

Why would you switch brands during the year? I could see viscosity if you are in a cold climate, but brands?

 

Amsoil or Redline

 

Mobil1

 

mobile 1 fully synthetic 10w30 all year round, but it doesnt get very cold in georgia so lucky me

 

Amsoil 10w30 year round
