Hi
A simple question really. I want to change my oil and find that I need a T 45 key to do it ( used to borrow from a friend who is no longer there ).
Now this plug does not need a great deal of torque , so why a T45 ? Do engineers rate these things to the diameter of the plug - or, as I suspect - do they specify them to push more customers into the dealers ?
The torque required on this plug does not need a T45, it could easily be done with a T40 which is a part of most Torx sets, but they make it a T45 which is not*. Is this to push the people who would do their own oil-change until they find that they don't have the tools, into the dealerships ?
I don't know about the numbers, but I'm sure it will have some effect.
* From my isolated mountain abode , I had to make a 65 mile round-trip to get one ( although I also needed to source a nasty little triangular-headed security-screwdriver at the same time )
