anybodyhere use restore engine product
they say it works wonders but i dont know about adding stuff to bmw engines

Don't do it!!!!!!!!!
Here's a Golden Rule:
If you can pour it out of a bottle, it can't fix whatever is broken.

I have found STP and Lucas to be good for bringing oil pressure back up in older, worn BMW engines. Have not noticed improvements or negatives of any kind from Restore.

Any of these products are only a temporary fix, Valvoline makes a similar product for about $4.00, but this does not cure the problem, just helps for a short time.
