Quite a silly analogy which shows a basic lack of understanding of the huge range of base oil viscosities including VMs that can be use to formulate a final finished oil grade. Any combination of 3cSt to 150cSt viscosity oils may be used to make 6cSt to 25cSt KV100 finished oils.
It may confound you but there is no issue whatsoever in doing so. The resulting viscosity is easy to calculate in blending two finished oils, which you can confirm with VOAs (see below) and UOAs, and ultimately in actual service with an oil pressure gauge.
It's probably worth repeating that Mobil has no problem in blending the Mobil made TGMO with M1 0W-40 or any other grade in their line up, nor do any other companies that I know of.
Many boutique formulators actively encourage the practice; so as not to be limited to any single grade that's offered.

It's not really a silly analogy at all. In fact that analogy was from a chemist I believe on here. Regardless, it's not about viscosity or mixing. My only concern is the mixing of different chemistry. That's all. Compatible yeah but that's sort of vague.
I honestly don't care who mixes oil. It's just a discussion topic for me. To each their own. Mix away.
One popular advertised advantage of synthetic oils vs mineral oil is their molecular uniformity, hence less oil drag.
While that is true for a given base oil, all syn oils use if not different wt base oils, various types of polymers in their formulation; most dispersants are polymer based in addition to the VIIs used.
Additionally all base oil chemistries are 100% compatible in API and ACEA oils, it is only the additives that can potentially be an issue and no formulator is going to use something that is known to clash, which is why they all say their oils are fully compatible with all other dino and syn oils.
Stridently criticizing blending is a waste of time because the vast majority of members who still have no particular interest in the practice know there is no harm in doing so.
You say you don't care but you don't miss an opportunity to ridicule those that do.
It's part of what BITOG is all about; questioning what is available in the market place and testing it. Intellectual curiosity shouldn't be stifled so why try?

I for one absorb the info you post about mixing different grades and what the blend achieves as far as VI and viscosity at operating temp and I truly believe the Caterham blend creates an oil we here in Canada cannot buy at any price or any store. And the research you do and post to ease others minds that aren't as open to trying new things is applaudable,and I thank you for it.
I see busters point however I am the kind of guy who likes the underdog. It does sadden me to see buster take every possible shot he can at someone contemplating perhaps trying a blend,since its not costing him any time,money or potential oiling issues,but he does bring up good points that should at least be observed and considered before proceeding with a blend.
Anyways keep posting as you do Caterham,I learn alot from your posts and they really help my comfort level.
From my experience reading your posts you have done in depth research and your opinion is always an informed one.
