Several oil companies offer various warranties on their products.
For example, in the specific case of Mobil Clean 5000, ExxonMobil says says:
Quote:
ExxonMobil guarantees that the Mobil Clean 5000 lubricant you purchased will protect your vehicle’s critical engine parts from oil related failure for 5,000 miles or six months, which ever comes first. If not, provided the engine was serviceable at the time the oil was installed, ExxonMobil will have your vehicle repaired and replace the oil at no cost to you.
Quaker State and Valvoline seem to have similar warranties, but require that one use their products exclusively since the car was new, and require detailed documentation.
Some questions about these warranties:
1. Has anyone ever needed to file a claim due to defective oil or some other oil-related failure?
2. Has anyone ever successfully completed a claim, and had an oil company pay for repairs? How much do the companies fight?
3. Does the existence of such warranties play into anyone else's mind when purchasing oil? That is, would anyone buy Mobil Clean 5000 over, say, Pennzoil conventional, simply because the Mobil oil has a better warranty? (They both meet essentially identical specifications, and I'm sure they're both excellent oils.)
