Don't know where you're getting your info but it ain't right.There IS a
difference between synthetics,Castrol syntec being the worst in every
SAE and independent tests I've read.I've been a proponent of Synthetics
since 1975 and have used Mobil 1 or Shell Rotella in every vehicle I
own.Amsoil is good but WAY to EXPENSIVE.Mobil Delvac is also excellent
but I can't get it around here.

If you say so, but relative to what? How much of a difference is there?
Test results are great and they're certainly important, but if they're
splitting hairs, they don't mean much in the real world.
Have you ever seen a test that rated a synthetic below a natural oil? If
the latter is good enough to do the job according to the manufacturer
of the engine, isn't it fair to assume that ANY synthetic will greatly
exceed the needs of the engine?
Is there any API certified oil that won't protect an engine adequately
for the 7500 miles that Hyundai specifies between changes, assuming one
uses the proper viscocity? I have yet to see any data that indicates
that there is. If you know of any, please post links here.
It seems to me that the quality of the oil filter one uses is probably
more important than the brand of oil, but that's another debate.
OK, but what's your point?
No argument here.
I don't think I've ever seen it.
This is all good information to know, but I don't see how it's relevent.
It's much like arguing about how many angels will fit on the head of a
pin; it really doesn't matter in the real world.
Mobil Delvac 1 is basically the fleet version of Mobil 1. I used it
years ago mainly because it came in 1 gallon jugs and was much easier
than messing with the loose quarts. It was designed for owners of
fleets of diesel engine vehicles, but it also met the API auto standard
of the time (this was in the late 70s).
I think Delvac 1 stopped following the gasoline engine specs sometime in
the early 80s and I haven't seen it for years so I'm not sure if they
even sell it still. They probably do, but I don't get to the Mobil
distributor very often and they only sold it throught a distributor back
in the 70s.
I can't say that I've ever seen a failure that I could attribute to the
oil, other than the lack of it. I run synthetics simply for the better
cold starts in the winters I live in. Otherwise, I believe it is
overkill for the type of driving I do the rest of the year.
