This week on Ron Ananian, The Car Doctor, Ron shares a shop story about a frustrating Chrysler 200C repair that turns into a bigger lesson: sometimes the smartest move is knowing when a car may not be worth fixing.

Ron also tackles questions about modern engine oil viscosity and why sticking with manufacturer specifications — along with shorter oil change intervals and quality filters — is still the best strategy for long engine life.

Plus, real-world diagnostics on a high-mileage Honda Civic with strange fuel trim readings, cooling system advice for a Chrysler Sebring, and a preview of next week’s conversation with Deputy Frank Sloup of the Pinal County Sheriff’s Office on traffic safety and smarter driving habits.

Good mechanics aren’t expensive — they’re priceless.
