Jake, did you know the M1 in a car that has seen only non synthetic can more often than not spring some leaks?
I disagree. I have switched over 12 cars that I have owned from mineral to Mobil 1, and I have never ever experienced leaks from the switch: Toyota Land Cruiser, Volvo's, BMW's, Jeep GC's, 3 911's, 1 930, even my Range Rover!. I am not saying it doesn't occur, I've just never seen it. The mileage of these cars at the time of the switch ranged from 10k to 120k. I switched the Range Rover at 70k, and it now has 165k no additonal or increase in the existing leaks!!

I've rebuilt engines, ran them on mineral for 10k then switched, no leaks.

I'm sure it happens, but if it were more often than not, I think I would have experienced it, as I have done this in a variety of cars since 1987.
1986 930
Gone:71,2,4 914's, 70T, 71T(RS),77S
