I will be doing an oil change myself for the first time ever. I can not decide on what synthetic oil to use...it seems that everyone agrees that either Redline or Amsoil are the best ones to buy (even though they may use another for price reasons). Can anyone help me out on deciding which to get?

 

Depends on the vehicle and how you run it.

I'd add Castrol 0W30, that's the German Castrol to that list.

 

Vehicle- IS350 planning to use 5w30 because of the hot summers in California and the long trips I do occasionally....I also plan to take the car to the track ever now and then.
