Hey this may sound stupid but i just bought my car about 6 months ago and just now got to about 3200 miles since i've had it and decided to change oil. I took it to a quick lube place around town and just told em to change oil check air filter and such. Well a few weeks ago i was looking under the hood and noticed that there is a sticker kinda by where the hood latches that say change with only 5w-30. Ok now the place changed the oil put 10w-30. this isnt gonna effect really much of anything will it. Some ideas of what other people are using and if they us 10w-30 or stick with the 5w-30.
