Well i have 7250 miles on my 03' and i am going in tommorow for my second oil change. I will not put full synthetic in till 10 thousand miles but i was wondering if there was any advantage to running a synthetic blend. Would there be any disadvantages, and what whould be a good choice. Thanks

 

You'll be fine with either but I would suggest saving your money for the full synthetic a few months from now.

A good conventional(Chevron Supreme, Castrol, Pennzoil) will be fine for the next few thousand miles.

 

Synblends are fine except for one thing - you have no idea what you are getting. Is it 99% minoil, and 1% synoil? Most blends are about 10-20% syn - for that, you could just do it yourself. Buy 5 quarts of one company's minoil, and add a quart of their synoil. Presto! A synblend that you know is worth what you are paying. I think it most cases, the oil companies are making out like bandits in this game.

I will say, that in my Cobra's TTC T-56 tranny, Valvoline DuraBlend gave the best shift qualioty - and I tried them all - literally, a dozen! I have a whole wall of various engine, tranny, and diff lubes in my garage, and more at The Lab.

There are some synblends that are better than full synoils (there are some minoils that are as well). A lot has to do with the purity of the base stocks, and quality control of the mfg, and the additives.

I am currently researching an oil which is a synblend for exactly those reasons - see my post on "Lubrication Engineers". As I have said more than once here, I would use boar mucous if I thought it was the best lubricant for my car.
