Avoid issues with your car by getting your oil changed when it needs! Not all oils need to be changed at 3k miles anymore, but if you use conventional oil, you will still need to get it changed at 3k. This customer went 5k, and you can see what happens only at an extra 2k - sludge build up. Don't make a simple maintenance service become a bigger issue! #oilchanges #mechanictips #cartips #cars
