Has Mobil 1 changed???

[NCGuy68]

Does this mean that M1 is no longer good for 9-10K miles before dumping it? I use a Wix filter changing it every 4.5K miles. Whats a better choice for extended oil change intervals ?

Hi Craig:
All I know is the stuff I took out of the truck after 1000 miles looked like I had not changed it for years.Real black and smelly Normally I could not see it on the stick after 1000 miles.

Up date have 1,000 mile on my wifes jeep Just checked it tonight and still looks good and it DOES not have that funny smell, Also have not had that valve tap on the cold morning starts snice I put in Valvoline
so it is Valvoline synthetic for now on and good by Mobil 1

I haven't noticed any funny smell with the Mobil1 in my 2000 SS as of now but it does look darker than I would expect it to. I may change to Valvoline or Castrol when it's time for an oil change. I ran Syntec in the 454SS and that motor ran nice and smooth and never burned a drop of oil. I don't think Mobil1 is as good as it used to be so why pay the extra for it.
