对了,我的车不漏油的话,是不是full synthetic和high m full synthetic差不多?
因为之前的大神说了high m 里面有添加物,感觉选择变窄了。。? |

d*******5 发帖数: 973 | 9 4月中换的机油,synthetic 5w20,第一次换synthetic的,车厂说9月中或5千mile换。
现在才开了3千多点,车显示只有10%机油,要换。车是14年CRV,
自己查一下,机油颜色浅褐色,还有很多,在两个点的上面。
为什么会这样,谢谢 |

c*******e 发帖数: 154 | 10 2010 corolla 开得很少,一直用的conventional oil,去dealer那想换synthetic oil
,他说不能换,一开始用的什么油以后就要用什么油,不能混,我看网上说可以换的呀
,另外如果换了synthetic oil以后还能再换conventional oil吗? |
|
c**d 发帖数: 3888 | 11 我用 Mobil 1 synthetic 每一万迈换油,没事的。不信的话,可以做个 oil analysis.
不过很老的车 (10万迈以上),如果一直用 dino oil,就不要换 synthetic 了。原
因是一直用 dino 油的发动机金属之间的磨损比较多,缝隙大。合成油的分子比较小,
不能填补这些缝隙提供足够润滑 |

发帖数: 1 | 13 You probably use the 5-30W or lower synthetic oil.
It is too thin for the old engine. BMW uses synthetic
oil for all its vehicles, I noticed my BMW is burning
oil too (after 5-6 years).
Burning the oil vs better protection to the engine(if you keep
monitoring oil level) + longer oil life. The industry chooses
to go with the later one. |
|
J****1 发帖数: 1769 | 14 synthetic oil last longer, better lubrication, and longer engine life.. and
of course more expensive.. But one main thing my mechanic told me is once
you use synthetic oil, don't go back to regular motor oil. Supposely it will
damage the engine.. |

如果说这是个synthetic,那么是一长一短,既然premium不够1.96那么是什么意思?肯

1.小小人免进,没空听你的偷换概念扯东扯西。
2.$3w以下的车子,full syn和传统机油没啥区别,随便你自己喜好。
3.6~8w mile以上的车子,不推荐full syn,要用也得用特殊的high mileage syn oil。
正文:
化工的咚咚我老不懂,求鉴定,但是generally speaking, full synthetic oil用更加
小的分子,有更加好的流动性和低温performance。总结一下好处就是:
1.对发动机的保护--我老持保留态度,不是说不相信这个理论,而是差别很少--这年头
很少有人把发动机开爆的。
2.半年或者7500mile换一次机油。比传统机油的3个月或者3000mile要长很多。
