2008 Mitsubishi Lancer 4 cyl Two Wheel Drive Automatic 24,000 miles
I bought a new Lancer March 2008, and had to get used to how loud the engine is. I even took it back into the dealership to have them check it out, and they told me that it's characteristic of the manufacturer. I confirmed this through numerous reviews of the vehicle, so my mind was at ease. Last weekend I got an oil change at a Valvoline instant oil change facility, and noticed instantly as I was leaving that the engine was a lot whinier than normal. When I went to work Monday, I noticed that it gets really loud and buzzy when I try to accelerate quickly, and there is even slight vibration due to the buzz. Any kind of acceleration is loud, but especially when I'm trying to do it quickly. It may be my imagination, but it seems like there is a slight delay and then a lurch when coming out of a complete stop sometimes, and at high speeds on the highway, it's harder to accelerate quickly. I'm thinking a lot of this might be because I try to avoid causing the noise, so my usual driving habits might be affected, and I might not be applying as much pressure to the pedal as I normally would. Due to my past record with crappy mechanics, I'm afraid that someone poked a hole or dislodged something with they were changing my oil. Or could a new batch of oil make it sound like this? I had them put in 4 quarts of Durablend. I honestly can't remember how buzzy the engine was a year ago when I first bought it, but I know that last time I got an oil change, there was no change in the tone of the car. Now I don't know whether to take it back to them since they are not true mechanics, or to take it to the dealership.
I am suffering from the exact same problem since I changed the oil in my 08 Lancer GTS, were you able to find what the problem was?

I haven't tried it yet, but maybe it'll work for you. When I think about it, the guy suggested I needed an air filter change (as usual) which I declined, and I remember him shoving the filter in as he was talking, and walked away saying he'd make sure to close it up later. Maybe he didn't? Let me know how this works for you. I'm going to try it in the morning.
I got a response at another forum that I needed to switch to Castrol oil organic (in other words, I needed to ditch the synthetic). I definitely don't think that's causing the noise, because my past few oil changes, I've gotten the synthetic blend, and I've NEVER driven off with my engine sounding like it does now. By the way, it's been like 2 weeks since the oil change, and it's not nearly as noisy at low speeds as it was right after the oil change, but when I really need some speed, it's still just as buzzy.

Hey just wanted to let you know that was, in fact the problem. The filter seemed to be in fine, but I unclipped and removed it, shook it out and made sure the BOTTOM of the area (the chasm where you place it back in) - made sure those clips were properly below and meshing (they dont seem to clip together).
I don't think it's the type of synthetic oil you use - I have always used standard 5W and it has worked fine.
Thanks for your help, appreciate it.

Yep, tried it this morning, and it worked for me, too. It was the bottom of the chamber that didn't seem to be fitting together right with the filter. Immediately took it on the highway for a little action, and it works great again. Such a relief for me - I'm sure for you, too.
