This is something that I think Mobil has changed since last Nov
Before that I had no problem
I know it is to soon to tell put 200 mile on jeep today with the Valvoline synthetic
Just pulled the stick out and it is nice and clear Took the oil cap off and it smelled normal just checked my sons 05 Grand with the 4.7 V8 . it has Mobil 1and it really
smell skanky. Has 1,800 mile on the oil and it is dirty as hell
what really got my attention is when I drained the oil last night and the oil was hot the smell was awful. The oil only had about 3,800 mile on it . It was the lifter noise
that morning that got me to check it out time will tell if the Valvoline does any better If any one come up with an answer I would love to hear what the heck is going on. The price for mobil 1 we pay this should not be happening
By the way these are all new jeeps with less than 25,000 miles. Valvoline was cheaper by almost 2 bucks
