If you mean common practice based on input here, which again is not a sufficient sample, I agree. Standard practice is a technical term. An example would be a standard practice in quality control. It is the only acceptable way to do something. Changing the oil at less than the recommended interval might be a common practice but it is not the standard practice. But that is nit picking.



Subjective. It has nothing to do with it for you. It might be the only factor to someone else, or a contributing factor to yet another person.

As to the plate needing to be dropped 5-10 times a year... mine has been off 3 times so far (once for sway bar bushings, once for cleaning/degreasing to track an oil leak, and I don't remember why the third time... maybe for fun?). Will be off again when I do the differential fluid in the coming weeks. Again, we are talking a subjective point of view. 5-10 times sounds like a lot to some of you, but to me, I'm likely to hit at least 5 this year. Dropping that plate is barely past removing wheels/tires to me, which I do a lot for cleaning. Am I strange? Probably. Certainly wouldn't be the first time I'd been called that.
