General Maintenance & Repairs - Best oil???

ok guys...i'm just curious i've narrowed my oil down to 2 choices...so i'm wanting you all's input so i can go ahead and get one of the two. Which would be better Mobil 1 10w-30 fully synthetic or Castrol Syntec 10w-30 fully synthetic. thanks guys...all opinions much appreciated :)

i go with mobil one 10w-30 fully synthetic its badass man, for some reason it makes a lil difference!!

I second that. :thumb:

after reading all the threads in here, i went with mobil 1, and i am happy with it

5W40 is recommended for Mobil 1. If you can find Castrol 0W30 European formula then go with that.

Mobil1 would be my choice...but just is case you would be intrested in something better than Mobil1 ,,take a look at Amsoil..

i had the opportunity to tear sevral motors apart wich were running different synthetic oil brands...for me Amsoil is king of the hill in the oil category.

May be a little more expensive than Mobil1 but it is the best oil out there..imho

I put 10w-40 Amsoil in my car today. Used Amsoil for a long time in our cars.

German Castrol 0W30

What about Royal Purple and Red Line

royal purple is junk, been watching to much horsepower tv, over rated and over priced, mobil 1 5w-40 here
