Mobil 1 oil

We used Mobil 1 15w50 in our bracket BB Mopar as recommended by original engine builder, (Nick Wilson). After a year & half of racing developed an oil pan gasket leak, dropped pan & found sludgy goo in bottom of pan. I asked around & after many calls to various oil companies & engine builders I put Pennzoil 15w50 platinum in, ran another year & half to rebuild time, pulled engine, disassambled & found no sludgy goo!!! Engine oil was always changed with WIX racing filter after 20 to 25 runs. One oil engineer claimed Mobil 1 wasn't holding contaminants long enough for filter to contain them. I don't really know why, I just know there is no sludgy goo in engine now.
