Just wondering if any of you guys run the MX4T in your Preds. I've been using this stuff for awhile now and I've noticed lately since the temp is going up it seems to shift crappy...I swear it sounds like Im running water cuz i canhear everything when I shift.....Is the MX4T synthetic not thick enough? OH ya btw its in triple digits here now.

 

i ran that stuff all last summer... i didnt have a problem... shifted fine for me... i was running the 10w-40 stuff...
