Synthetic oil at one time meant oil that was engineered, that is built up molecule by molecule without resorting to oil derived from dinosaurs. Think Mobil 1. That is no longer true. A few years back the "courts" determined the term synthetic oil could be claimed by all oils that display the same or similar characteristics regardless of whether it was "engineered" or refined from dino oil. That understood back to the answer. Synthetic oil resists breaking down. That is its viscosity range ( e.g. 10-40, 5-40) will be sustained longer than non synthetics and under harsher circumstances. So, if you want to extend your oil change interval, or you want the extra insurance afforded by synthetic, it's the way to go.
The short answer is yes, sometimes. If the part is not one that typically wears with use and does not require a lot of labor to install/remove it may make sense. One extreme example make-sense used part would be a steering wheel or headlight housing. On the other extreme would be clutch plates or brake hydraulics. The techs can make a recommendation based on their experience with the part in the particular auto.
Generally yes BUT you have to understand that neither the part or the labor wiil be warranted. We would not have knowledge of the source of the part nor its history.. Most electronic parts and some mechanical parts cannot be tested before installation. We prefer to use parts from vendors we have found to be reliable and who warrant their parts including installation/removal labor.
Most manufacturers specify "Light Duty" and "Extreme Duty" recommendations. Extreme descriptions often include frequent idling, stop-and-go traffic, dusty conditions, trailer pulling etc. The "Extreme Duty" conditions are normal for some folks and call for more frequent changes.
Parts that we use are from reliable manufacturers, delivered to our facility and carry a warranty.
Many modern automobile engines have a cogged rubber belt turning one or more shafts where cams open the intake and exhaust valves at the appropriate moments in the engines revolution cycle. In some engines the valves open far enough to occupy a space occupied by a piston during another time in the cycle. Engines having this property are called "interference engines". If a timing belt were to break or loosen sufficiently to "jump" a one or more cogs the valves could be struck by a piston and be damaged. To avoid this potential expensive damage manufacturers recommend the timing belt be replaced as a preventive measure.
The Owner's Manual or Warranty Booklet are good guides for when to do preventive maintenance. They usually call for oil and oil filter changes at regular mileage intervals, along with tire rotation . At less frequent mileage intervals they usually call for mor extensive maintenance actions that include changing air/cabin filters, spark plugs, serpentine belts and perhaps a timing belt. When a trained technician has your car on a lift the technician can spot other areas that may need attention such as CV boots, worn brake pads or perhaps gaskets that are beginning to leak. Experienced technicians know where to look for potential problems.
