Look, we've all had jobs we didn't like or weren't thrilled about. If you consider it for the long term, you're bound to get something out of it. Say you dedicate 2 years to your oil changes. An employer will see you have dedication and drive to go somewhere if you're pursuing bigger and better things, and that you didn't get fired because your work is at minimum satisfactory. Get a reference that your work is superb and now you're talking bigger and better things in your future.
Start looking into what it takes to get your dream job. Talk to people that are currently working your dream job and see what they are looking for out of an ideal candidate. Then of course be that ideal candidate.
It's not hard at all, it just takes a little bit of discipline and a good view at your long term goals as well as a mentor or two.
Also, even if you get your dream job at your dream company, the work will become somewhat uninteresting at times. Big deal, you have to remember it pays the bills and it's something you should be grateful for.
