I have recently done something outside the realm of my automotive experience thus far: I’ve bought an honest-to-god new car!

I’ve never paid anyone to change my oil before and I’m hoping not to start now, but I’ve also never had a car with the warranty in force. I know in theory there should be no problem with this (Magnuson-Moss and all that) but I’m curious how that really shakes out in the real world.

What particularly concerns me is that I bought a Subaru that has one of their new family of engines in it that apparently occasionally likes to develop oil consumption issues (which admittedly isn’t that different from most of their _old_ engine families, but I digress). Their acceptable oil consumption guideline is 1qt/1200 miles, but apparently they will replace engines for somewhat lower consumption levels at their discretion. So far so good with mine, but I’m concerned that I may miss out on getting a new engine if I show up 30,000 miles down the line with a car that’s eating, say, 1qt/1500 miles and only a stack of NAPA receipts to show for maintenance. Even if they couldn’t legally deny a clear-cut warranty claim, will that greatly color their discretion when it comes to a discretionary repair?

Anyone have any insight into this, especially the dealership-employed dopers? It’s not a lot of money (it calls for 7,500 mile oil changes, so only 5 until it’s out of warranty), but I would rather do them myself.

I’ve changed my own oil and did other maintenance such as air filters on new cars. I kept all the receipts as proof. Fortunately I never had a warranty issue where this has come into play.

New car for me last spring. I changed my own oil last fall. I have the receipts for the oil and the filter. On the filter invoice I wrote the date and mileage at which I changed the oil. That’ll do for me. I’ve followed the same policy over the years with my previous brand-new car and two brand-new motorcycles. I’ve never had to invoke an engine warranty, but I wouldn’t expect trouble just because I did my own maintenance (as long as I actually did do all the required maintenance on schedule, and kept reasonable records).

Keep in mind that it’s not in the dealer’s/manufacturer’s interest to capriciously deny warranty service. Customers talk to other customers, all the moreso now that we have the internet. Once word gets around that a manufacturer will do its goddamndest to avoid honoring a warranty, people will be much less excited about buying cars from that manufacturer.
