It would be useful to point out the negative side of Mobil 1 as well. I mean we don't want bias. We want facts or at least very strong deductive reasoning. The company's behavior is valid as well.
For instance, Mobil 1 discussed PAO basestock in the past. Now they will not, claiming its proprietary information.
That sort of thing rubs people the wrong way. Of course they are within their rights. The problem is their rights are completely irrelevant to customer perception. It leads people to believe their products have less PAO than before. Or even to doubt there's any PAO at all in some formulations. Rightfully or wrongfully so. It makes no difference.
- In the 1970's Mobil 1 claimed their oil was good for 25,000 miles.
- In 2009, Mobil 1 EP, their longest drain oil, is claimed to be good for only 15,000 miles.
- It's accepted as fact that modern engines are dramatically easier on oil than their 70's counterparts. Unleaded fuel, fuel injection, computer controlled engine management etc have allowed OCIs to increase in length not decrease.
The consumer can only reckon either:
- Mobil 1 lied to them in the 70's
- The definition of propriety is hose job
- Or it was a hose job even before it was proprietary
* The views expressed above are not necessarily in accord with those of the actual poster, even though they are the same person.
** It is possible that a mile was not 5,280 feet in the 1970's.
*** It is now thought to be plausible that, due to the excessive use of dope, someone high up in the weights and measures department, could have simply placed the decimal point in the wrong spot. It was supposed to be 2,500 miles not 25,000. Which is consistent with the 3000 OCI mindset at the time.
