Here is some help on the various oils and how they compare in
Standard Performance tests 
.. I would be reluctant to use any lubricating fluid without knowing the composition of the oil..
You can actually save money by using a synthetic such as AMSOIL which can give you up to 36,000 miles (or 12 months)between oil drains.. with improved performance and wear protection over the 3,000 mile stuff.. and believe me this isn't snake oil..
