I couldn't help myself. I was directed to this forum and asked to look into. When I started to read this and as I followed the responses, everyone seems to now believe that the m1 isn't a full synth. Thought I'd post this on here and see what the consensus is to this topic. bob

Topic: MOBIL 1 is NOT SYNTHETIC - I FOUND
PROOF!!!
posted 07-20-2002 12:27 PM
Hello-
In many synthetic debates on these forums, I've
often stated that at least at this current date,
the "new tri-synthetic formulated" Mobil 1 is NOT
a true synthetic oil. I've also stated that in
the past, it probably was a real group IV/V
synthetic. I've said that it is a hydrocracked
petroleum - a group III oil. However, every time
I say it, people disagree with me.
Guess what: I found proof!
First, a reference item for comparison: Delvac 1
(mfd. by Mobil) is a very high quality synthetic
oil designed primarily for fleet use. If you do a
google/yahoo on it, you'll find lots of spec
sheets online - not much marketing gimmick around
this stuff. You'll find, however, that in that
marketing there are some FAQ, and one of them
clearly states that this is a group IV/V
synthetic, not a hydrocracked petroleum.
NOWHERE in ANY Mobil marketing info is this
question ever addressed about Mobil 1.
Now, the pour point of Delvac 1 (5w-40) is -55F.
The pour point of new Mobil 1 (15w-50) is -38F.
But, alas, one could argue that they are
different viscosity indicies, right?
Here's the kicker: I was in Target today and I
happened to wander into the automotive section.
Here in the Midwest, not many people buy heavy
weight oils. I stuck my hand in the back of the
shelf and pulled out an old bottle of Mobil 1 15w-
50. The info was printed on the bottle - not on
stickers like new bottles. And, there was no "tri-
synthetic" stuff written anywhere.
I found the missing link. The pour point of the
old Mobil 1 is -55F.
Indeed, new Mobil 1 is NOT a true synthetic.
Take care,
