Have you ever noticed that when you tackle one repair around the house you find other things that need fixing? This can apply to your car, also.
On the lift for an oil change, we sometimes see a marginal part or component that could spell trouble down the road. When that happens we alert our customer before it becomes a problem. This provides both the knowledge and time to make an informed decision about the needed service or repair.
The cost of an oil change is minimal compared to the additional benefits of having a periodic inspection of those parts of your vehicle that you seldom see.
