Smokey Mc-Pot?

I don't need to do oil analysis, I can feel the difference, the Motul oil made the engine feel more smoother, whereas the generic oil from local motor factor made the engine feel its working harder. Engines aren't simple piece of machinery, those oil form an important part of the engine keeping it lubricated amongst other things. Some cars are also more sensitive than others. I doubt the likes of Castrol, Motul, Mobil etc spend millions on R&D to develop the same product as an el cheapo generic piece of oil.

if its not opened then use same brand and same forumla
Yeah but you realise it can be reverse engineered and pretty much copied right?
Ahhhhh, oil and tyres, the reason Motors exists!
Which is nowhere near as easy as it sounds!
Plus certain components are often patented, or simply secret (as patents can give the game away to competitors). But the main point he was making was that there is a lot of difference between a premium brand oil (Castrol, Mobil, etc) and a bargain basement one.
All the big players will reverse engineer the competitors products and know them fairly well, however the smaller companies simply won't have the time or funds to do so, nor would it help them that much as they wouldn't compete well in that area of the market. So as similar in performance and protection as premium products may be to each other, there's a world of difference between them and the cheaper ones.
This was probably due to the fact you'd just removed 10k mile old oil and filter and replaced it with brand new stuff.
Yeah I know, it was terrible to see the Halfords BTCC cars and all those Comma (the makers of Halfords oils) sponsored teams having so many engine failures, they really were uncompetitive.
Yes you are right, the additives they use won't be identical to the ones used by some of the premium brands, some of the base stock won't be identical either, but the effects are normally sufficient to provide an almost identical level of performance and protection.
Lots of people would be surprised at the sort of oils used by many motor race teams, and these guys test their cars hard on dyno's using those oils, which are often the much cheaper brands, such as Comma, and those oils are also used by many main stealers and independent garages.
My point still holds though, that mixing oils of the same rating and type but different brands should have no ill effects, which you agree with also
Who would reverse engineer an oil for Halfords?
It will be an off the shelf offer from an additive company
If your cheap oil made that much difference that you could feel it, It would have almost killed the engine with excessive friction.
Engines are a simple piece of engineering, they use the simplest bearings ever, one where they don't ever make contact metal to metal when at normal operating conditions. If the oil you used made the car feel like it was working harder, then those bearing must have either been filled with oil with massive parasitic drag or you were making metal to metal contact which would kill the engine very quickly.
Far more likely is that you gained placebo effect of thinking now you had better oil the engine was running better.
Their oil is made by Comma, so just rebranded Comma oil in all likelihood. It is an off the shelf oil that has already had R&D long before they rebrand it.
I know exactly what it is and I can tell you that it's not developed by Comma
Of course there is metal-to metal contact in an engine, otherwise they would be a need for anti-wear additives. Bearings have no oil protection at start up and will wear until they rotate fast enough to create the hydrodynamic wedge that keeps them seperated.
Much like a water skier on water - without movement they just sink into the water.
Seriously, do you read my posts or just leave out the ones that already have that written in them?

Unless the two oils were different grades/types or one was contaminated that is quite simply impossible.

Who said that they never make contact
