This involves 2 types of Schaffer Motor Oils. Their normal gasoline engine oils (701, 703, 9003D, 9004, 9005) and their European engine oils (8007 and 8008). When I go to their chart and go by API certification codes, e.g., SJ, SL, SM, SN, I see things I don't understand but want to understand.
For example, the European oils are good for SL and SN but not SJ and SM. I'm just trying to understand as I want to use the European in my GS300 (SJ) and LS400 (SJ). My 4Runner and LS430 are SL so it is no problem. Would it be a problem in my older Lexus? I've emailed Schaeffer Corp this morning.
