网友提问(这个问题很尖锐的）：为什么BITOG网友使用美孚机油后进行旧机油测试(UOA)都发现相同环境下、使用了美孚机油的旧机油样品中铁Fe含量较高？

“For unknown reasons, Mobil 1 tends to show higher Fe in various oil analysis reports compared to other branded oils in similar driving conditions. I’ve been on this website long enough to know that it’s a real characteristic of the oil. We understand that this may be nothing ‘significant’ at all, and that the scientific process is far from good considering the used oil analysis samples we see on here. Can XOM confirm that the perceived higher than normal Fe is not a problem?”

这个问题美孚乘用车合成油专家Ray McDonald答案都是含糊其辞、泛谈发动机构造（flat cam vs roller cam、使用什么金属材质等等）、更换机油周期、驾驶环境、防冻液是否渗漏导致机油润滑性下降等等；网友进一步追问问什么同样条件下、BITOG网友持续一致的得出使用美孚机油后UOA显示Fe铁含量高、美孚专家并无再次释疑

Iron particles in used oil are to be expected, as the iron in engine components, such as cam shafts, timing chains and gears, piston pins and rings and cylinder liner, wears down during normal operation. To determine if the level of iron particles is higher than it should be, a wide range of factors need to be assessed. These include whether the car is driven in normal or harsh operating conditions, the amount of highway driving versus city driving, whether the engine is subjected to stop-and-go driving, and the volume of cold starts and temperature extremes the engine endures. Also, car and engine model and frequency of oil changes will have a significant effect on how much iron ends up in the engine oil.

All these factors can impact the amount of iron that goes into the oil, so it is necessary to consider all of these elements when establishing what a typical level of iron should be. For example, a highly engineered vehicle/engine design operated under relatively mild conditions (e.g., mostly highway operation) over a standard oil drain interval may generate iron levels as low as 20 – 25 parts per million. Alternatively, an engine of average design, operated through more severe conditions such as an extended oil drain interval, may yield iron levels in the range of 200 – 300 parts per million. Based on the iron-content numbers of the UOA analysis typically described by BITOG users, the stated levels should not be a concern and show that Mobil 1 is protecting engine parts as promised.

Also, used oil analysis (UOA) is only one dimension when it comes to assessing engine oil performance. Ultimately, UOA should be combined with engine inspections and measurements to more accurately assess the performance of the oil.
If iron content of a UOA is considered higher than expected, the next step is to determine the cause of the premature wear. In order to do this, evaluate other data points from the UOA report to obtain a more complete picture as to what’s going on in the engine. Premature engine wear is often due to mechanical issues, not the oil. For example, elevated levels of lead and/or copper, particularly in combination with a positive glycol dilution test, would indicate that there may be a coolant leak within the engine. Coolant dilution in the engine oil (which would occur from something like a crack in the head gasket) would cause rapid acceleration of wear metals in the engine oil.

网友问题2（这个问题也很尖锐）：Ashland化工集团的广告声明以及旧机油检测中的高含量铁Fe成分引起大家怀疑、怀疑什么呢？就是你家美孚机油对顶凸轮轴保护效果没有竞争品牌那么好；英国石油公司和Ashland化工集团做了好几个月广告、分别宣称在标准seq IVA测试中能提供4倍和8倍抗磨损保护功效、你能不能发表一下看法？
Ashland’s claims in conjunction with higher Fe in UOA’s have caused suspicion of whether Mobil 1′s cam wear protection is as good as competitor oils. BP and Ashland for months ran ads claiming 4 and 8x better wear on an industry standard Seq IVA test. Can you elaborate on this?

美孚专家回答：美孚集团不应答任何竞争品牌市场宣传

amphibia补充：Ashland是valvoline胜牌机油的母公司、BP英国石油就不解释了

As stated in the answer to the previous, similar question, ExxonMobil does not comment on competitive marketing claims.

美孚专家解答关于美孚赛车油产品线和赛车油对民用车三元催化器毒化

背景资料：老式发动机使用flat cam顶凸轮轴靠滑动摩擦，需要机油中含有大量抗磨剂比如锌和磷；但是这两种元素都会毒化三元催化器；现在许多新型中高档发动机用roller arm cam滚轴摇臂式顶凸轮轴靠滚动摩擦，对机油中抗磨剂要求大大降低
网友问题1：我有一个1960年产老式高性能V8发动机，希望机油保护顶凸轮轴、也要控制沉淀、满足日常驾驶要求云云；我担心30粘度不够保护、又觉得40粘度太粘稠；请推荐机油云云

I’ve got some old (1960s) high-performance American v8 engines with moderately aggressive cams and high spring pressures, but not wild enough to be considered “racing” engines. I want oils that control deposits and hold up to everyday driving, which rules out most of the racing oils that are available and would protect the cam. Most of the premium street engine oils today are tailored for newer engines with roller cams, overhead cams, and very light spring pressures. So I’ve been using diesel engine oils like your M1 TDT and Shell’s Rotella T6. The downside is that these engines are really more set up for a 30-wt oil and develop high oil pressure on these HD engine oils, wasting power and stressing the oil pump drive gears. From reading oil analyses, it seems like your M1 0w40 oil might fill the bill a little better. Its still heavier than I’d really like, but it looks to be a little thinner than TDT 5w40 at operating temperatures, and still looks like its got an additive package that would work well with old-school cams and moderately high spring pressures. Do you have a better recommendation?

美孚专家回答：
1 美孚普通5w-30足够保护、corvette超跑和许多赛车都使用5w-30云云；
2 如果是顶凸轮轴弹簧是高强弹簧和凸轮轴形状是很激进的，我们建议使用美孚一号赛车油系列的0w-30，这一款机油增加了额外的抗磨剂配方，能够提供足够保护

Mobil 1 5W-30 should have no problem providing protection for these type of engines. In fact, all Corvettes and many race teams use Mobil 1 5W-30. Note that for extremely high cam/spring pressure, high-performance applications, we also have a product called Mobil 1 Racing 0W-30, which has a boosted anti-wear system and would provide an additional option for you, should you feel more comfortable with this.

网友问题2：美孚不建议民用街车使用美孚赛车油系列，请问唯一原因是否是毒化三元催化器？还有其他原因吗？

Mobil does not recommend the Mobil 1 Racing oils for street use … is this solely because of potential premature degradation to the life of catalytic converters? Any other reason?

美孚专家回答：没有其他原因；潜在影响三元催化器是唯一让美孚公司不不不推荐美孚赛车油系列使用在民用街车的原因

No. Potential impact on catalytic converters is the only reason we do not recommend Mobil 1 Racing for street use.

网友问题：正时链条会不会对机油带来更加严峻考验、要求更短的换油周期云云；我用美孚EP5w-20、对于使用正时链条的顶凸轮轴发动机、你们美孚EP系列机油能不能像你们宣传的那样、坚持到15000英里（24000公里）换油周期？
Do timing chains place noticeable stress on engine oil, requiring shorter OCIs than engines that use timing belts? I am now using M1 5-20EP. Is your EP oil suitable for the 15K OCI as you advertise with overhead cam engines that use timing chains?
美孚专家回答：美孚extanded performance（EP）配方经过最严格发动机测试云云、能够满足正时链条发动机15000英里（24000公里）换油周期

Mobil 1 Extended Performance products have been tested in some of the most severe operating conditions that engines can endure and under extended service conditions, and will have no problem protecting timing chains at 15,000-mile oil change intervals.

美孚的两条产品线性能和认证PK：
美规金瓶子Extended Performance (EP） vs 美规普通银瓶子

网友提问1：美孚Extended Performance(EP 美规金瓶子那个）比普通美孚一号如何？看规格两者都不错但是差不多、请问普通美孚一号和EP配方美孚一号有什么真实区别？

Do the Extended Performance oils offer better overall performance than the regular Mobil 1 line, and if so in what ways? The specs. for both look very good and very similar. What is the real difference between reg. M1 and EP?

美孚专家解答1：不能透露配方但是我们能说美孚EP配方在几方面不会被其他任何全合成机油超越、包括高温保护和抵御发动机有害沉淀；美孚一号EP配方是特别为今天延长了的换油周期设计的、能够保证15000英里（24000公里）换油周期；EP含有独特增强保护配方

amphibia理解：言下之意、美规金瓶子EP比普通美孚强一些

While we can’t disclose any proprietary information, we can say that Mobil 1 Extended Performance is unsurpassed against other full synthetics in high temperature protection and resistance to the formation of undesired engine deposits. Mobil 1 Extended Performance is designed specifically for today’s longer service intervals and is guaranteed to protect for up to 15,000 miles or one year, whichever occurs first. Mobil 1 Extended Performance has a unique formulation with a boosted level of protection and performance.

网友提问2：为什么金瓶子EP的5w-30不能满足那些银瓶子美孚5w-30能满足的汽车厂家规格（amphibia：网友问题说白了就是为啥金瓶子好像牛逼、但是反而银瓶子车厂认证更多？）
Why doesn’t M1 EP 5W-30 meet all the same mfg specs that M1 5W-30 does?

美孚专家解答：金瓶子EP产品线是特别针对今天那些超长的换油周期 - 15000英里（24000公里）或者1年；金瓶子EP满足绝大多数汽车厂家建议的常规API、ILSAC和ACEA认证；美孚银瓶子5w-30涵盖额外的OEM认证、这些额外的认证也许建议其他换油周期

Mobil 1 Extended Performance is designed specifically for today’s longer service intervals and is guaranteed to protect for up to 15,000 miles or one year. It meets the standard API, ILSAC, and ACEA industry specifications recommended by most auto manufacturers. Mobil 1 5W30 covers additional OEM specifications which may recommend other oil intervals.

amphibia整理美规金瓶子EP水货 vs 银瓶子水美

1 专家回答云里雾里

2 我理解金瓶子超长换油周期EP系列油之所以没有0w、应该是说明当今科技下、粘度调节添加剂viscosity index improver（那种高温伸直、低温蜷成一团的机油添加剂成分）无法做到不被剪切损耗；导致超长换油周期下、粘度调节添加剂失效 - 机油被打回基础油原型

3 国内机油推荐：

a 1万公里一换、天气不冷的话：用5w-30银瓶子足够

b 1万公里一换、天气很冷的话：用0w-30 绿瓶子足够

c 要撑到15000英里（24000公里）换机油（比如进藏以前）：那么用金瓶子EP的5w-30保险

网友提问: 美孚ECF 0w-40（european car formula欧洲车配方、应该是国内的水美0w-40）为什么使用后被剪切到仅剩下30粘度；虽然这个油一开始就是仅仅比30粘度粘稠一点点云云
I’d like to know if you could elaborate on why the Mobil 1 ECF 0w40 almost always shears to a 30wt. Granted, it starts out just a little above a 30wt, but it’s not really a 0w40 if it spends over half its useful life as a 0w30 or is it?

美孚专家回答：美孚0w-40经过众多各种环境测试、一致出色保护和性能；我们不同意你的仅剩下30粘度说法；我们严格测试证明0w-40是真实40粘度云云；要不然保时捷、奔驰AMG、道奇SRT超跑等等把0w-40当成出厂灌装油

Mobil 1 0W-40 has been tested in numerous engine types and over a vast range of operating conditions, and has always demonstrated outstanding protection and performance. We disagree with the contentions that Mobil 1 0W-40 “almost always shears to a [0W-30]” and “spends over half its useful life as a 0W-30.” Our research and vigorous testing confirms that the product is a true 0W-40 viscosity that protects engines in which it is intended to be used. It is this level of continuous protection across the entire oil change interval that allows engineers at Porsche, Mercedes AMG, Dodge SRT, and other high-performance automakers to have the confidence to put Mobil 1 0W-40 in their engines before they leave the factory.

网友提问: 如果某发动机规格指定使用低粘度机油比如5w-20、那么如果用高粘度机油比如美孚0w-40有没有什么问题？我这么问因为我一直在几个福特modular型号发动机中使用0w-40机油丝毫不烧机油而且气门系统也安静一些（使用5w-20是略烧机油、速度是1万公里1升）
Are there any known issues with running a heavier oil, such as M1 0w40, in engines spec’d for lighter oils, such as 5w20? I ask because I’ve been using 0w40 in a few of the (non VCT) Ford Modular engines with zero consumption (5w20 was 1L/10,000Km) and a quieter valve train.
美孚专家回答：在这些应用条件下使用0w-40没有任何我们了解到的问题
There are no known issues with using Mobil 1 0W-40 in these applications.
