You are correct: as a result of the merger with ExxonMobil, the Exxon synthetic line was merged into the Mobil line. With Mobil having been the synthetic developer/leader through the years, it was only natural. IMHO, Exxon did a wonderful job in its joining with Mobil in recognizing each company's strength and keeping/reinforcing those individual strengths. No one use area went away, just product duplication was eliminated, especially in areas where there was recognized strong product.
