Search. We have discussed oil and shockproof repeatedly.
Quick response:
Red-Line is good stuff. Shockproof should only be in the trans/center and will last for a long, long time.
Royal Purple is probably as good if not better.
Neither is really necessary unless you are tracking your car or like to spend too much on oil. Mobile 1 or any other good synthetic is probably fine for the street. Spend money on good filters.
Purolator Pure Ones are some of the best.
No reason to go looking for something more obscure IMHO. And if you mention Amsoil we will kill you.
