So expensive engine oil really does work.

I knew a BLOKE who knew a bloke that used hydraulic oil from a JCB in his car.
UTO - universal tractor oil - is suitable for engines, gearboxes and hydraulic systems, so should be fine. I wouldnt put it in a brand new turbo diesel, but no reason it wont work in older cars if you get the weight right. Thought I'd seen this thread before. I was hoping that it was resurrected because Scuffers had got the go-ahead to conduct an independent test, that would be nice!
Even better would be a set of proper engine dyno runs in a test cell. I suppose it's theoretically possible that Millers have come up with a formulation that offers the protection of a thicker grade, but with a drastic reduction in friction over cheaper oils, but until we get proper independent testing it's hard to say much.

Suppose its like going to McDonalds and getting a Milkshake versus a Diet Coke, the Milkshake collapses the straw and gives you brain freeze whlst requiring much more effort.
You forgot the bleeding from the ears after visiting les arches gilt and drinking the former 
; leaking connectionss and burst oil pipes and/or oil filter on cold start might be a better comparison .tank slapper said:
The difference between a 0W40, 10W40 and 15W40 is the viscosity of the oil at low temperatures. All three of those oils would have the same viscosity at 100C which is close to the engine operating temperature. If you live in a hot country, then you don't need 0W oil. If you live in a cold country which experiences sub-zero temperatures it might be essential.
I live in the tropics so doesnt dip below 25 degrees, I have developed a small leak on the head gasket only. Thinking this is probably the 0w oil so will change back to 10w40 on the next change. Only seems to leak when not running and cooled down (literally small drip), if not means a new head gasket needed. Mobil 0w40 is the recommended oil by Porsche themselves which is why I used it.
You may find that it still leaks even with a slightly thicker oil when cold. Oil at the operating temperature of the engine is much thinner than at ambient temperature, so it could be that the leak is stopping because wherever it is leaking from is closing up due due to thermal expansion. If the leak isn't closing up, then I'd expect to see it get worse when hot as the oil can flow much more easily.
It's probably worth a try though as you don't need the low temperature characteristics of 0W oil and it won't hurt to use 10W.

Seems there are quite a few here who know quite a bit about engine oils. Whereas I dont.
I have used Mobil 1 in my crossflow Caterham/s for many years, and it `seems' to work very well
in that oil pressure and engine reliability remains good after many many years of fairly `heavy' use.
However I was told recently that mobil 1 was manufactured for close tolerance engines (Honda I think the bloke said) and would not do much for my engine type.
He recommended I change to a Millers fully synthetic oil. So I am in a bit of a quandary, as to whether to take his advice and change to Millers, or stick with what I know (for years) has seemed to work very well in my particular engine. A sort of `if it aint broke dont fix it' situation.
I remember a long time ago reading about tests carried out by BMW / Mobil where they ran an engine continuously for a massive length of time (I think they were talking about a year, but it may have just been the equivalent of a continuous years motoring) and on stripping down the engine found that it still had exactly the same tolerances as its `as manufactured tolerances' measured at the start of the test, seeming to imply that no wear whatsoever had taken place.
Given the above, what oil (manufacturer / type) would be the general recommendation be for a 145 bhp supersprint crossflow? Any advice would be welcome.

it's a well known fact that thinner engine oil will result in improved mpg and increased power...
nothing to see here... move along.
Except maybe this..nothing to see here... move along.
