标题: 看来subaru还是去原厂保养比较好。。。
居然要清洁节气门，水平对置的引擎的保养还真是不同。

关于节气门清洗，其实新款的legacy和outback已经不需要节气门清洗了，新设计喷油嘴位置已经很靠近气门，不会在造成积碳，impreza还是要洗。但不知道中国4S店为什么要把节气门拆下来洗，因为在澳洲我还没见过有人拆过，拆节气门要断电，会造成ecu的记忆丢失，手动车在行驶中很容易熄火，太危险了，还费时，所以没人拆。多轰油门让电脑relearn，差不多1，2个礼拜才会好
其实subaru有专门的节气门清洗剂，下图蓝盖子的，我们这里是每次保养喷一瓶，跟拆节气门清洗的效果一模一样，中国的方法真是吃饱了撑着（澳洲是12，500km跟保养一起做的，中国最好每2W公里做一次

图中红色箭头的地方，那里有根真空管子连到进气歧管，把管子拔开，喷进去，引擎要热的，喷半罐后等个15分钟左右再点车，这时会很难点着，持续点到着不停的轰油门，会有很多白烟出来的所以找个空旷通风的地方，剩下半瓶一个人在车里轰油门，另一个人不停往里喷直到喷完。不要一次全喷进去，不但会对感应器伤害很大，还有可能造成引擎内部液压锁死。

PS 中国的竟然有小引擎盖，澳版怎么没有？？、

清潔後感覺有分別或什麽的嘛?

也就是保持引擎的功率
听说，不做的，开久了，发动机容易坏。
其他的流行车，我还没有听过要做这个的，好像是引擎本身的原因。

offical answer from subaru faq:Q: My Subaru’s maintenance schedule includes an Upper Engine Cleaner to be performed, what is this?
A:
Engine power output is created by the burning of fuel in a vehicle’s cylinders. As petrol is a hydrocarbon fuel, made up of hydrogen and carbon, after combustion it leaves carbon as a by-product or deposit. Over a relatively short period of time the carbon deposits on the walls of the combustion chamber, the piston crown (top surface), and on the valves, can result in the deterioration of engine efficiency. This may lead to poor fuel economy, reduced power and harder starting.
To overcome this situation, the factory has formulated ‘Upper Engine Cleaner (SA459)’, which is a concentrated combustion chamber and induction system cleaner. This product helps clean and purge gum, varnish, and carbon deposits. Using this solvent during scheduled servicing has proven to be a valuable form of preventative maintenance.
If your vehicle were subjected to regular stop/start driving, short trips, or poor fuel quality, the build up of gum, varnish, and carbon deposits would be far more rapid. In addition to ‘Upper Engine Cleaner (SA459)’, we suggest the use of ‘SA718 Fuel Additive’ to maximise your engine’s protection against such concerns.
Both products have been specially formulated by Fuji Heavy Industries, the manufacturer of your Subaru vehicle, to be compatible with the Subaru horizontally opposed engine and it’s technically advanced electronics. These products are available through all authorised Subaru Dealers.

我也去AUTO BORN买了瓶类似的东西，但是不知道怎么用，怕乱用坏了车，下次还是拿到33那边去给他看看

之前每次去subaru做service都有这项清洁，subaru主要是保养太贵，一年要做两次，其他新车基本上一年一次，宝马一年半一次，不明白为什么subaru那么娇气，车是好车。。。。。

I think it is beacuse it box engine. it is horizontal. not like the vertical one, where all the dirt and slug will easily go to the bottom and drain out, all the dirt will stay almost whatever it is. if you do not serve it frequently, it will easily die.

further, how much is the service?
Thanks.

引擎没有什么毛病就不要乱清洗这个那个的，就按时换所有oil和filter就好

作者: younggun 时间: 2010-12-16 10:52
really depends on the car

回复 10# younggun

一般的是300到400，最大的一次800多，还好我的3.0R不需要换timing belt，听他说要换的话差不多要1500。。。。。。

宝马一年半做一次，一次1000左右，算起来跟subaru差不多了。。。。。。

subaru虽然是好车，但是毕竟只是个日本牌子，保养配件维修如果跟一部宝马差不多的话，我觉得不太值得花这个钱去开它，而且每次去dealer一趟也很不方便，要耽误上班时间要不然只能周六上午，每个几个月就要去一次很不方便
