I'm using Pennzoil Ultra 5W20 in both my '06 Mustang GT and wifey's '08 Miata GT. I'm convinced it is a great oil.

Yep, we need to know if your cutting corners, 1/4 mile racing? DD? ect.

Second this. Pennzoil Ultra is great oil, and can be found cheap on deals throughout the year, even at Walmart it really isn't pricey at normal prices.

Amsoil or RP for me.. Probably don't need it but it's worth the price I think..

Hay thanks for the replies! My driving style is pretty mellow, ill punch it from time to time! I love this car! That's why I want only but the best!! I read up on amsoil website and it seems to me that the signature series is the best out of the XL and OE!!

The threads on which oil to use are endless in this forum!

I would go right to the Signature Series and change it once per year if you aren't putting alot of miles on it. Amsoil calls for 5-20 or you can also use the 0-20 for a better cold start. Here is a link if you would like http://www.amsoil.com/storefront/alm.aspx.

If you need help getting prodcut for the cheapest price possible please let me know.

Yeah, I don't get it really. I have a paid preferred membership to amsoil, but realistically, it's much like asking which pen in better to write with. So long as you do it before the oil you actually do use, breaks down, and do so regularly, your good. That's the only caveat, and I'm lazy, so I want to go with the longest lasting.

Perhaps with the "uberest eva!" stuff your bearings might last a whole 500mi more, big whoop.

Worst advice ever!.. Do not recommend something you don't know about..
