As the folks above have posted, please take any wise-crack comments as comments made in jest and fun. A-holes are not welcome in this Forum, and just about all folks who post frequently are definitely not A-holes.
There are certain topics/questions that get asked very frequently on this Forum, like this question regarding motor oil preferences, and there is a mountain of information in this Forum for those frequently asked questions. Unfortunately, the search tool in this Forum leaves a lot to be desired, so finding previously posted information can be a challenge. As such new folks often try to search, find very limited valuable returns for their search inquiries, and end up asking the question in a new post on the Forum.
So, when a frequently asked question pops up in the Forum as a new post, the wise-crack comments start to pop up by the regulars in the Forum. But, to be clear again, it is all in jest and fun. As you can see, folks have provided the OP with links to existing relevant information contained in previously posted threads.
