So back to oils.. Is it a possibility that the only difference in the 925 spec oil is the florescence color that is added? When you look at the technical data of the oil it doesn't seem to be out of the ordinary from other oils in the same category..
The following is straight from the product data page from castrol oil:

LOL No. And another member found out that they have done away with the dye now.
These days oils can be wildly different depending on what the car manufacturer specifies.
Look at the difference between Castrol oil and BMW specified oil, both same viscocity, and probably made by the same company
Boca, what jagtoes said is spot on.
If you have a water pump that works and works well- it may be infinitely better than the new one you wish to get
Sometimes it comes down to luck of the draw, and fear drawing a bad straw if asked to roll the dice again.
Another concern that you should have; your car/engine was put together in a proper factory with precision tools and folks who only work on this engine. That is not what you will get at a dealer replacing a water pump.
Queen and Country......Your last statement is precisely why I have not started pressuring and/or pursuing the replacement with the same enthusiasm I had initially. What I call your reference to amateurs replacing what the factory installed as "Collateral damage". The results of trying to repair something while breaking other items along the way. So very true and very well said! Thanks. For the time being I'll live with the coolant smell and keep my reservoir topped up.
I saw on Power Block TV that Valvoline has introduced a new oil formulation specifically made for new GDI engines. Supposedly it has additives, detergents and whatever else to stop/prevent carbon build-up on the intake valves and to do other fancy stuff.

Good News- Bad News- Mind blowing news, on new oil choices.
Good News,
Many more brands of oil for the 5.0 Jaguar engine have become available in USA now. Partly because there are so many more Jaguar models that use the same oil, even the Fpace.
Bad News,
They all cost more than the oil purchased from dealer.
And none of them are proven like the Castrol.
However, I have not known Redline to make a product that did not outperform everything on the market.
The Mind-blowing,
My favorite oil, that is highly proven, its insanely cheap, ($20 for a gallon, $10 after rebate) and readily available; now has Jaguar certification (sorta)
In the oil community we wondered why it did not because test data showed that it did everything Jag spec was looking for and one of the only ones to do so.
Regardless of certification, its the only oil I would trust not to leave deposits as its a true group 4. Its long been known in the enthusiasts community to be one of the best oils period.
I have used it for over 150,000 miles on my engine with 280,000 miles with great results, its the only one that goes 6 months without getting quart low or 20% loss.
Its competitor's test prove it to be better in the one area we care about (evap loss)
