Just wanted to enlighten many which may not be aware of the new standard ILSAC GF-5 Many improvements over GF4.
Here is the link & good info from Lubrizol:
GF5 Lubrizol
I know many including myself use quality synthetics in their vehicles, look for the GF5 rating on your bottles to ensure you are getting the latest stock.
Not all oils have this rating.
Current stock including Mobil 1 & Castol Edge Etc should display the ILSAC GF5 on rear of bottle.
