Synthetic Oil Myths
During the early development and formulation period of synthetic motor
oils, certain additives and techniques were used which made synthetics
incompatible with some seals found in motor vehicle engines. There was also a
question of whether or not synthetics could be reliably mixed with
conventional oils. Because of these facts, synthetics received a bad
reputation, which has caused modern synthetic manufacturers to have to
re-educate people about their products. There ar

来自主题: Chicago版 - 科普以下full synthetic oil
我喜欢的dsb终于出现了,板门弄斧一下,毕竟我老有自己的车也才1年。
1.motor oil的功能是lubricant,full synthetic在high heat下,没有附加物质产生
,regular oil有,这些杂志会对有物理上的磨损。所谓的换油,主要是换掉这部分。
(我说了主要)
2.5W-20,5define了 weight,20定义了viscosity,5表现的是oil在机械上的重量,附
着情况,20表现了sticky。这个number,no good no better,你得匹配engine。
3.3W来衡量车,general speaking,it it correct,因为3W刀的车基本上都是垃圾

oil更focus engine的heat和high performance。
这些都是理论上的,大叔说的没有错,full synthetic只是在理论上,or chemistry

对于这个我是外行,现在也没有机会接触这个。但是有时候也看看这方面的paper,挺矛
盾的。为什么觉得难呢?瞎说说吧:
1. pathway/metabolic engineering归于synthetic biology。虽然为了骗funding,不
得不这样。前段时间来了人做seminar,说是synthetic biology,结果就做了点E.coli
里产 PHB。把人恶心坏了。可是能说他不是synthetic biology吗?这方面好好干也可
以,需要点突破性的东西。
2. 做这行idea最重要。大家连western都不用做,靠一些小电影儿就能弄出大paper。
可见实验手段不是啥制约因素。牛人嘛,克隆表达两三个基因就迷倒万千众生。Craig
Venter那种猛男除外。矛盾在于,有时候过分玩弄小技巧挺没劲的。不玩弄吧,干点啥
好呢?

今天去dealer那里问了一下,说换回来没问题,所以就换回来了。
主要是换了synthetic oil之后发现吃油很厉害,一两千miles之后就明显油很少了,低
于最底线,原本以为换了synthetic oil之后能撑比较长时间呢。车是2009年的camry,
前面几年都是按期去dealer那里换机油,最近这大半年开始自己换,而且换成了

synthetic gut的核心是单根粗纤维,multifilament的核心是很多根细纤维编成的粗纤

不过另一种说法是单纤维核心和多纤维核心都算synthetic gut,不过前者是synthetic

synthetic优点:
1) 维护间隔更长,一般高级油滤7000英里,采用精滤油滤的可以达1万多
2)更好的高/低温性能,同样的viscosity,低温段比普通更低,举个例子,chicago冬
天用矿物油零下30F启动车非常困难,如果是manual transmission要热车20分钟才能开
,用synthetic基本上发动就可以走人了。当年冬天零下20多,我的老麦早上发车,发动后连档都挂不上,P/N switch马上就拉坏了。换了掺50%的synthetic的80-90,再冷的冬天都是马上就走。
流动性是啥?viscosity?这5W30不定义了viscosity?

来自主题: Biology版 - 请问什么叫Synthetic Lethal?
假设基因A和基因B一起突变之后造成细胞(或者你的模式生物)死亡,而单突变A或者B
并没有死亡,就称为synthetic lethal。一般预示着基因A和B在功能上有关。
另一种情况是基因A和基因B各自单突变的时候造成部分的细胞或者模式生物死亡(比如
分别是20%和30%,这称为incomplete penetrance),此时如果双突变100%死亡,也算
synthetic lethal。但需要注意的是如果各自单突变致死的比例相加之后接近或者超过
100% (比如mutant A 50%,mutant B 60%致死率),虽然也造成synthetic lethal,
有可能A和B并没有任何关联,只是简单的叠加效应。

普通oil是三个月换一次
synthetic oil据换油的人说是每5000mi换一次
我的车半年多开了1500mi
这么算下来我是不是三年以后才需要去换机油?
这么算下来用synthetic还比普通的便宜
不知道我理解的对不对

my oil change deal says
"Valid only for location purchased. By appointment only. Additional fee for
synthetic oil. Additional fee for vehicles requiring disposa"
so i guess synthetic oil must be better than ordinary oil.

来自主题: Automobile版 - Regular Oil vs. Synthetic Oil?
I have a 2004 camry, It uses regular 5W30 oil.
Last time when I did oil change, I was persuaded to use synthetic oil
instead of regular oil, the technician told me that I should keep using
synthetic oil.
Today when I went to another place to do oil change, the technician told me
I should switch back to regular oil.
What should I do?

来自主题: Automobile版 - 2012 Civic 机油必须要用synthetic的?
今天打电话给买车的dealer,service dept的人把资料调出来,然后说the car calls
for synthetic oil。倒是也不贵,$58.12。问题是必须么?manuel上至说要用Honda专
用的机油,有提到synethetic不过好像只是强调即便是synthetic的机油也要是
certified的。
还有个问题问Honda的用户,这屏幕里vehical information->maintance里面oil的百分
比,是要到多少以下才意味这要换机油了,我现在新车刚开了4个月,开了5100miles,
机油的百分比是40%。
谢谢!

dealer's synthetic is full or blended. You gotta asking.
If full synthetic, $58 is ok.

来自主题: Automobile版 - 换Full Synthetic Oil 不见得好。
以前一直用一般的oil, 不久前从Costco 买了好几箱Mobil 1 full synthetic oil. 第
一次换上,才开了2600miles, 今天换transmission fluid, 顺便检查了下engine oil,
发现已经到了low level, 于是加了半瓶oil.
full synthetic oil 一般可以8000到10000换,但对有些吃engine oil 的车如果车主
从来不自己检查车,换这种油反而不太好。
