RE: [DML] Brake Fluid



Do remember that Mobil one synthetic is not really synthetic anymore.  After
the lawsuit Mobil 1 started using a Group III base for its oil (actually a
mix of group III and IV with most of it being group III)... just like what
they were accusing Castrol for.

A real synthetic is made from a group IV (PAO's) and is what Mobil 1 used to
be.  If you remember M1 used to be significantly more expensive than
Castrol.

Most "regular" oil or "dino juice" on the market today is mostly group II
based.  Castrol regular oil used to be mostly group III based until they
came out with their "synthetic" branding.  This is why it was one of the
best oils on the market. Currently the regular Castrol is a mix of group II
and III base with most of it group II.  

I still use Castrol because it's still one of the best regular oils on the
market and I think the only one that still uses any group III base in it (I
think it's less than 20%).

Synthetic blends you see on the shelf are generally a 50%-50% mix of group
II and III bases.

If you look at a bottle of "synthetic" oil and it says "Made in Germany"
than that is the good stuff.  In Europe you cannot use the term "Synthetic"
unless the base is almost all group IV or higher.  IIRC this is the case
with Castrol Edge and Castrol Syntec European formula (at least for a time).

Your private label / gas station brands of oil are almost all exclusively
group I and II blends.

This is why brands like Redline, Royal Purple, Amsoil, etc. are so much more
expensive.  They are generally Group IV+ bases.

"Synthetic" is very much a marketing term for Castrol. Their
"synthetic" oil is just highly refined dino oil. Mobil sued them over
this a few years back and remarkably lost. There is a reason Mobil (and
other legitimately synthetic oils) cost more than Castrol but the
average uneducated consumer just sees the word "synthetic" and gets all
excited.

Remember in the US "synthetic" is a marketing term.... it does not have
to
actually be man-made. In Europe that is not the case. It may still be
mineral based.
