Something I have noticed recently with Castrol GTX Magnatec after changing over to Mag in my 2013 Mustang GT (5w20) I noticed when I check the oil the I seem to get blotches of oil going up the dipstick a few inches something I have never noticed with any other oil. So I am wondering could Magnatec be sticking to metal like the adds say? So three days ago I changed my oil in my 2012 Nissan Pathfinder 4.0 V6 with GTX Magnatec 5w30 and after checking the oil after 50 and 110 miles I have the same thing oil walking up the dipstick. Not solid all the way up but in spots? And yes I have the correct ammount of oil in both cars. Has anyone here noticed this happening? I am going to change the oil in my dads 2016 Ford Escape with Mag this week and see if I get the same results?
