Lots of manufacturers have had specific blends over the years and yes they are normally not directly replaceable off the highstreet shelf. They are great for scaring the average punter into using the manufacturers quoted oil... funny that!
As stated for our relatively temperate climate 0-30 10-40 will be fine, anything in between.
You can get some £2 tat motor oil from Homebase thats got the same rating as some £20 a litre oil, are they the same ? No.
The numbers quoted refer to the ability to lubricate at various temperatures thats all. Different oils have different characteristics, thinner/thicker etc. Some fully synthetics are thin, so great for a newly run in engine, but bung them in a 5 year old 75,000 miler and they will be used up quickly as they will just nto stay where they should due to wear. Thats why you can get oils for older engines as they are designed to be that bit thicker.
Oil tech has moved on massively year after year, its a very different tech to 30-40 years ago, and most decent brand oils will do a very very good job in most modern cars.
Your only issue could be if your in warranty period, if your outside it dont worry.
Most handbooks even say different oil to use if particularly hot or cold temperatures are expected, its simply there to ensure the oil is usable at the temperatures the engine will be dealing with.
