Honestly, I used to think the same thing. Unfortunately, it's not that simple. I have 6 cars. 3 are always in the garage when not in use. The other 3 are parked outside. Of those, two are driven regularly and one is parked because it's only used for RallyX. I've never had an issue with the 5 but the RallyX car had a ton of moisture in the oil every time I've changed it at the start of the season after letting it sit outside for 6 months. At first I thought I had a coolant issue but then realized that it was just attracted moisture.

Aside from that, how much are your cars worth to you? "Wasting money" is a questionable statement for such a low cost maintenance item that has a high cost if you have a failure due to that issue.

To each their own. It's the internet and opinions are like a-holes.
