也贴一个:2019 Toyota Rav4 3年没换机油里面是什么样的?

徒劳
楼主 (文学城)

我以为他要把零件全拆了清洗,他说只要频换机油就行。是这样吗?

他说的是但愿能再给它个机会换换油清清干净

但是太多功夫了而且还不能保证,还是把它整个换了。

我的理解是说先每星期啥的换一次机油,然后再逐渐增加间隔,这样可以慢慢的把油腻融化了洗出来。

那些油腻早已把油道都堵死流不到润滑面了

再说了机油本身是溶不化油腻的,只有汽油或ATF才行。

没这么说。车主将换引擎。作者说希望给引擎个换filter试试看,不能保证寿命。

不能保证寿命是因要清理后才知磨损。引擎卸下来就容易搞了,国内换缸套活塞也不少。

ct200h也有大半个缸都是肉汤或黄泥浆的,不是没及时换油,而是积碳漏油等的机器设计问题。

对于己sludge的机油,最常用的办法就是用含清洁剂的新油反复地将其稀释,溶解。

是我记错了,这是下面有人跟贴如是说。。。

I agree with whatever is said about need for timely maintenance. Compression is good, engine is running and some oil did drain out. If it were me I would put quality synthetic oil and do couple short interval oil changes and gradually increase oil change interval. You would be surprised how clean the engine would get without tearing it down and cleaning it after few oil changes.

有人说加煤油,idle几分钟 放掉。 总之就是要用Engine Sludge remover,

感觉老美两极得厉害。一边是无知无畏跟着感觉走的;另一边是porject farm这种完全靠实测数据说话的。
