Depends, though. Advanced Auto Parts sells Mobil Clean 7500 semi-synthetic for $.95 per quart (buy online pickup @ local store).

 

When an oil manufacturer sells a "semi-synthetic" or a "blended" product, how do you know how much "synthetic" is blended into the product......10%, 20%, 50%, etc. ??????

Isn't kind of like orange juice made from concentrate? How much water is added to the concentrate to create the quart of juice???

 

Would anyone be interested in GM's written position on different oils?????

As the Arabs would say, "I spit in the eye of those who tell untruths" !!!

 

I'm a big fan of Royal Purple. My dad uses it in his HHR and I use it in my SAAB. It helps with low end power and fuel economy. Check it out

Or how do you know it the synthetic is on top or the bottom

Yet another useless oil thread, although hillbilly's "Scamsoil" comment did make me chuckle a little...
