There is absolutely NO WAY any one oil can solve every issue these differing variables can dish out.
There is a place for additives, it's just the purists who can't see the obvious. Many who decry the testimonial actually point to one if it confirms their bias...
The engine oil companies have responded to the need for additives for older engines and race engines very well. There is now a very good range of High Mileage oils, thick oils like 10/60's, ultra low friction high Moly content oils, classic car and high Zinc content oils available. The new generation of oils will outperform a normal oil plus some can of snake oil and you won't be conducting a chemistry experiment with your own engine in terms of possible side effects.
There are folks who need to buy oil additives, if you can only obtain cheap bulk oil and importing higher quality engine oil is too expensive, then using a can of additives to boost a poor add pack does make sense. That situation is very different to adding a can of snake oil to a top quality engine oil and wrecking the way the chemically balanced add pack functions or causing an unwanted side effect.
Other snake oils appeal to those looking to ignore their engines maintenance manual and their instruction never include a warning that adding solvents or thin oils is a risky business. They fail to warn the user that an oil leak, blocked filter or damaged turbo bearings can result from dissolving sludge and varnish whilst driving around. The snake oil instructions also fail to warn you that you may be invalidating the power train warranty, as you are ignoring a specific warning in almost every handbook, which says, DON'T USE SNAKE OIL ADDITIVES.
Im using that snake oil, MMO right now. I take my truck to redline with it in the sump daily. I have put thousands of miles on my truck with it in the sump. According to you and your self proclaimed expertise it should have thrown a rod years ago.
