It doesn't, because it isn't. it's better to not do it. if you're going to add oil only to run the engine for a few minutes and drain it, then you should use the same oil you normally use. That's just costing you extra money unnecessarily. it's only a couple of bucks for a quart, which is a *lot* less than the 4-5 quarts for your method, *particularly* if it's synthetic. an extra quart can extend the life of the engine, which saves money in the long term. According to what I learned in the Army, Not necessarily. If the oil level is too high, it does not contact the moving parts evenly. You can get air pockets oil galleries, and less liquid oil to cool parts such as piston skirts. The "foam" also sticks in place and doesn't drain back to the pan, and insulates parts from normal heat transfer. -- PeterN |

You can accomplish the same thing, well actually much more, by just letting the oil drain overnight. No need to waste a quart of oil. i originally said that, although not doing it overnight. if i'm not in a rush, i let it drip for 5-10 minutes longer. the point of the extra quart is to accelerate that process.

There is no real Mac malware. There has never ever been a verifiable report of any normal user ever having an infected Mac since Mac OS X began and very little in ye olde days before that either. Only theoretical scaremongering by anti-malware sellers and utter nonsense from anti-Apple know-nothing morons. That's not exactly true. While it is true that there have been very few OS X *viruses* found in the wild, there is plenty of malware, mostly in the form of trojans masquerading as legitimate commercial software that shows up on pirated software sources. It is true that most of the highly publicized malware that has been reported are proof-of-concept exploits (not in the wild) written by security researchers who often work for firms that sell security software. It's also true that there are OS X bot nets, but those are typically the result of infections by trojans masquerading as pirated software. There is also adware out there, typically bundled with otherwise legitimate software. None of that stuff can be installed without the user'S permission though. In general all Mac users have to do to avoid such malware is simply refrain from downloading software from untrusted sites. -- E-mail sent to this address may be devoured by my ravenous SPAM filter.

Nor would there be the need for the security updates described in https://support.apple.com/en-us/HT201222 Most such security updates are proactive rather than reactive. Apple has very good security but it's not totally impenetrable. True. Security updates are to stop *potential* and *theoretical* issues ... they aren't there to stop actual existing malware, because there is none. There is plenty of malware (mostly Trojans masquerading as pirated commercial software), but no viruses in the wild. -- E-mail sent to this address may be devoured by my ravenous SPAM filter.

The difference with OS X is the vast majority of malware is not viruses and requires user permission to install. In general this makes OS X more problem free in that regard. -- E-mail sent to this address may be devoured by my ravenous SPAM filter. I often ignore posts from Google.
