欧盟对中国电动车征收保护性关税，但是该措施不适用于混动车。混比电好？

不清楚这个是不是正确。
我有一个油车，查了说明书，改变了以前5000公里/3个月换油到建议的5000miles/半年换油。

即使车不太开，也不能2年不换机油吧？机油在车里几个季节温度变化

全合成机油可以保证两年。

如果长期只用电机不用汽油发动机，PHEV会不定期的启动运转一下汽油发动机，特别是冬天。

It’s not just about miles: If you don’t drive your car a lot, your oil still needs to be kept fresh. Even if you drive fewer miles each year than your automaker suggests changing the oil (say, 6,000 miles, with suggested oil-change intervals at 7,500 miles), you should still be getting that oil changed twice a year.

Why? Oil becomes less effective as it ages, and by not getting the engine warm enough, excess moisture that forms in the engine will not be removed, which can lead to shorter engine life.

网上看了一下，很多人说可以一年，超过一年基本不行。
美国有实验室，可以花几十元寄去检查，检查结果会告诉你油是不是差了，有人每两个月寄一次油，结果11个月最优
