Anyone heard of synlube and what are your thoughts on their views.
Having a Saturday night google and managed to somehow stumble across this gem.
Would anyone here be keen on trying out 150000 miles without a change?
Also has anyone ever used their products and do they live up to the self proclaimed epicness the company speak of?

The whole article kinda annoys me. I would rather spend £80 and 2-3 hrs per year for 15 years doing oil swaps than test that theory and need a new lump after 5.... Any daredevils here

Snake oil.
We used to have a petroleum engineer on this board a long while ago, his name was "Road Rage" and he made some oil change related posts and some results from oil testing. While it is true synthetics last longer and manufacturers who use them have 10,000 or more oil change intervals (Toyota and BMW) your filter will still become a problem. It will get full of silica and when it gets clogged or fails you basically will have tons of ground up sand suspended in your oil that will harm the engine.
Your filter will not last 150,000 miles and you would need to find how to change your filter without changing the oil, which most likely you drain it, then pour it back into the engine. If you are going to go through all that trouble, why not just change the oil and be on the safe side? Even with good new filters, you are still going to end up with contaminants in the oil over that many miles.
150,000 sounds like a horrible idea and you still end up buying oil because the engine will burn SOME and you have to keep adding over time. There is a different "super oil" gimmick every couple years that somebody makes some money off of, this sounds like one of them.

As vader1 mentioned it's the filter that I'd be concerned with. I can see the oil almost never needing to be changed especially on cars like Porsche that burn a more oil, so there's always new oil being added.
Even if the oil could last that long, I like to have the car up a lift a couple times of year minimum just for visual inspection. If it's already up there; just change the oil & filter!

So they claim 15 years and 150,000 miles but their warranty requires you to check the oil level (in your engine) every month and change it out every 5 years or 50,000 miles. The engine filter? Every 10,000 miles or every year (and 25,000/2 yrs or 50,000/5 yrs)! 
Again, given then you have to drain and refill the engine to change the filter, you're still paying for labour (at best) to do that work or else you're changing the fluid anyways, just to be safe. Oh, and you have to send them a card with lubrication levels every time you check your lubricants.
TL
R - they're no different than anyone else in terms of filter changes and hence, fluid changes as well BUT they require extensive record-keeping to boot.
The automatic transmission fluid has to be changed every 3 years or 30,000 miles. That's more than the OEM requires for any of my vehicles with an AT!

Supposedly it has better thermal conductivity, which supposedly makes the engine run cooler (up to 25*C).
Higher thermal conductivity means that the oil sheds heat more quickly but that only means that the rest of the engine heats up more quickly as well. The heat has to go somewhere, so it'll saturate the cooling system and engine itself fairly quickly. You'll effectively reach the stable operating temperature fairly quickly but that stable operating temperature doesn't necessarily drop because the oil can shed heat faster, if that rate exceeds your cooling system capacity.
The oil is only one part of cooling the engine - if the rest of the system can't take advantage of it, you don't really gain anything.

This seems like the answer to a question no one ever asked. Changing oil is easy to do yourself and cheap to have someone else do it. If oil life expectancy is keeping you from motoring, your problem goes far beyond oil selection.

Who needs life time tranny fluid? It's easy and infrequent to change...

Try changing it on a modern ZF automatic... The pan, filter, and fluid all have to be done at once (sold as a kit). Comes as kit and costs about $500 to change; done it several times... Better to pay $500 at 60K then thousands later for that "life time tranny".
