If you start going 10/12/15000 miles on a oil change, even though your dealership knows Amsoil is good oil, it is going to use this to void his obligation. My Dodge has the lifetime warranty on powertrain, therefore Iam sorta stuck with thier reccomended oil changes where it states no longer then 6,000/6 months under no circumstances and 3,000/3 months under severe service, what 80% of vehicles fall under. Its a good double warranty deal with Valvoline and if you read the fine print, they cover alot.
I would put money on the fact you would have to have a TON of support for a warranty like Valvoline's. Similarly, those warranties that have "150k+ guarantees" and such are going to be interesting. I'd be willing to be you're going to have to prove the when and where of every oil change you ever made, which likely rules out DIY oil changes.
I don't disagree that you can run into warranty issues with dealerships at the drop of a hat, but there is more wiggle room for the consumer (technically, not necessarily the ignorant reality of some dealerships) than you'd think.
Although I know this isn't the best source, when it isn't written down on paper, but I called on several occasions about running a warrantied oil engineered for longer than conventional OCI's on my Pontiac and was told each time that I would not void my warranty if I went beyond the Oil Life Monitor (OLM) reading. There was also nothing that confined me to a specific number of miles.
Although I don't disagree you can run into problems with a dealership and/or manufacturer, I don't think they can technically force you to downgrade to a lesser quality oil due to mileage restrictions. They would likely have to prove maintenance negligence, which they couldn't do when they have a proven UOA in their face that says they are wrong.
Convoluted, but oh well. Nothing to argue about, just food for thought.
