Whenever I drive, the car engine sounds abnormally loud. It sounds loud whenever I accellete and at rest it sounds loud too. The car drives fine (I think, I can’t really tell if there’s a huge difference), I am just worried that it may be a transmission problem, or an expensive muffler problem. When my car is in park, the engine DOES make a funny noise, but it’s been there the whole time I’ve had the car. The loud engine has been going on for months with no performance problems, but now I am just getting concerned. The engine noise started AFTER I took it in for an oil change, about 6 months ago (after not having an oil change for a long, long time). I am looking to get another oil change, but not if it makes the car even worse. Will not getting an oil change for a long long time, and then having an oil change cause engine problems? Or, to cause the engine to sound too loud, like it is revving?
I think the engine should purr, not roar.
This is a 2000 Infiniti i30.
And, how much would it cost to repair…
