Well here's what I found, Granny.
oil and filter change typically costs between $35 and $75 for conventional oil and $65 to $125 for synthetic oil, but the price varies based on location, vehicle type, and service provider. Factors like vehicle age, the specific type of oil and filter required, labor costs, and additional services will affect the final price.
We usually don't just get an oil change though. We may get a new air filter, other fluids like transmission fluid if necessary, the windshield washer topped off, brake fluid checked .. just a complete service job. It may cost around $100 or more.
We just got a front end alignment on the Buick. A one-time alignment would have cost about $180, I think. For $50 more we got a lifetime deal so we never have to pay for an alignment on that car again.
