老问题，每年millage开得很少的车还要按时换机油吗？

[hagerty]

开的少两年换绝对没问题。所谓不开也会氧化就是扯淡。也许三十年前的机油真的会氧化。现在的机油绝对不会。

ChatGPT的回答：

If I use synthetic oil and only drive 1,000 miles a year, is it okay to change oil every 2 years?

ChatGPT
It's generally recommended to change your oil every 7,500 miles or 6 months, whichever comes first. However, if you only drive 1,000 miles per year, it would be fine to change your oil every two years. Keep in mind that synthetic oil can last longer than conventional oil, so you may be able to extend the time between oil changes even further. It's always a good idea to consult your vehicle's owner's manual for specific recommendations and to have your oil checked periodically by a professional.

开得少的车往往有水汽混进机油，一年换掉比较好，俺偷懒一年半换出来的废油就很难看了
