Guess my hunch is right. Nagpapalit na kasi sila ng package to give way to CI-4/plus ratings IMO. Hmmm... to buy or not to buy?

It's very temting kasi for 1,000+ for a 5 ltr jug semi-syn delo sports.

I was just thinking, about putting a magnet on the oil filter, which kind of over thinking it, would the magnet pull out the molybdenum from the oil itself? I've read (from Wikipedia) that molybdenum is paramagnetic, unlike zinc which is diamagnetic. Any thoughts?

To answer my own question from "http://www.frenergy.com.au/pages/FAQs.html":

Q: I use Molybdenum DiSulphide compound as a friction proofing in all my engines, Will Powermag Oil Filter Magnet units draw the Moly from the oil??I am not sure if Moly is magnetically attracted.
A: Paramagnetic metals have a small and positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons, and from the realignment of the electron orbits caused by the external magnetic field. Paramagnetic materials include magnesium, molybdenum, lithium, and tantalum. So answer, only slightly attracted

Not much of answer, but it gets closer.

A magnet will not pull the moly out of your oil. Moly bonds to surface metals for one thing and it also will not be pulled out by a filter maganet of any kind.

Got some research about it, they had a little spatter about it in another forum: Brand of Oil Filter? - Page 5 - Mazda MX6 Forums: MX6 Forum

Bottomline, the molybdenum compound they usually use in motor oils is molybdenum disulfide, which, in a way, is comparable to salt (NaCl, Na is Sodium, very volatile metal), it's very different from pure molybdenum.

Caltex Delo Multigrade

Pretty solid oil

Base Number, 12.2
Phosphorus, 1360ppm
Zinc 1480ppm

It also has over 100 boron and close to 250ppm moly in it.

The US Chevron version is just as good.

Almost as beefy as redline, though it's not a synthetic oil perfect for 8000km to 1000km oil changes with that high TBN.

Data sheet for all TOP 1 products.

There regular engine treatment is just a viscosity modifier, not to impressed with it. It does not have any ZDDP in it at all. The green one has moly but the amount is unknown.

Hi doc. How about Caltex Delo (Silver) Monograde 40. I use this oil from time to time on short OCI (3k kms max) - interchanged with the Caltex Delo 15w-40 oil.

By the way the shipment has arrived in the post office in North Hollywood. My friend is picking it up today or tom. Can't wait to get the filters. I'm having it shipped here together 8-10 (5 quart) bottles of Mobil 1 TDT.

Delo siver can be considered semi synthetic as it has group III oil blended in with it. and it has greater than 1000ppm zinc so that's a good thing. If it's anything like the Delo 400 it probably has a good dose of moly and boron in it as well. Delo oils are for commercial vehicle use so they are stout.l
