I installed SF MTL-P (12cSt) in my '99 Escort ZX2's 5 speed transaxle. I ran the OEM Mercon to 8K then Redline D4 to 62K and last week installed the MTL-P thanks to reviews I read here on the forum. I will say that the 5 yr old Redline D4 held up quite well and provided nice crisp shifting and drained out a nice clean red. The MTL-P (with 200 miles on it) is a bit smoother and allows an easier downshift into first when in slow traffic. Like forum member mechtech said, the 2nd gear synchro action is noticeably smoother. MolaKule certainly knows how to brew up a sweet trans fluid.
