Maybe what's going on here is the widely different prices for both service and the PPM. People on this board have got quotes anywhere from $1,355 to $340. That's a massive varience. At $1,355 it probably doesn't make sense, at $340 it's probably a good deal!

The other catch is what the service is costing. Again, there seems to be a wide varience, anywhere from $25 up.

That's why this is making sense to some people and not to others I think.

Flopshot:
I do understand what your are saying, but didn't realize what you are paying for an oil change. I pay $29, or actually I would, but my dealer through in the frst year for free. So, for me, sure with PPM I'd be locking in the price, but at a rate 175% higher than I can just go to the dealer at. Could oil increase in cost 175% over the term, sure, but I doubt it. Actually, time is a factor as well. Let's say you went halfway before the price increases. Now the price would have to increase 350% just to break even. That's a heck of a lot of "insurance". That said, in your case, the premium over just going to the dealer is only 15%. Not sure I would do it or not, but I do understand that's a reasonable amount to pay to lock it in, so certainly for you makes sense.

By the way, that's assuming oil will go up. As a guy living in the largest oil producing region in North America, currently oil is going down, and is expected to continue to do so over the next year. We're feeling it, though not a "crash" or anything like that. After that it's very hard to predict, but will probably stablize.

So, it depends on three things:
What are your service costs?
What is the cost of the PPM?
What is your best guess and comfort level at the future of oil costs?
For the poster that can get the PPM for $340. Go for it. I'd jump on that in a heartbeat. For the poster that got the $1,355 quote, unless your oil changes are uber expensive, it's probably not worth it.

Hope that makes sense.
