Why do some test results showing synthetic oils superiority state “as tested by an independent lab”? Why don’t you state which lab did the testing?
First, it is generally against most companies’ policies to release that information to consumers, as well as their vendors. It is partly due to confidentiality and partly because some labs do not have customer service departments and can’t have retail customers calling them. Instead, take a look at how long the particular company has been in business. It would be terribly hard for a company to stay in business for a long period of time if their advertising is not accurate. Also, the Federal Trade Commission takes a very dim view of false advertising and comes down hard on companies whose products don’t perform as claimed. Besides that, if the data is not accurate a competitor is likely to initiate legal action, which can be very expensive. Finally, if a person wants to, they are welcome to take a sample of the product in question to any lab that has ASTM equipment and have the tests run themselves.
