I dodged the bullet on that one by not using synthetic oil in my car. If I did, I would be sure to change it at least as often as my owner's manual stipulates so I don't void my warranty.
It should not need to be replaced under normal conditions.
im guessing that your talking about the alarm/keyless remote. You will find that you have to get closer and closer to the car to be able to unlock it. You should replace the battery when you have to be within about 10ft from the car.
Your car's owner's manual will specify how often you should replace the coolant. In general, every 24,000 to 36,000 miles is about right, or about every 24 to 26 months.
Radiator hoses and heater hoses should be inspected yearly and replaced when neccessary.
This depends on the oil that goes into the car. If it is synthetic you need to change it every 10,000 miles if it is regular than it needs to be every 3000-3500 miles.
Depends on how many stops you make each year. There is no set time or mileage. You inspect them periodically and replace as necessary.
This varies so much from car to car. My car does not even have a replaceable fuel filter. Best advice is to check your owner's manual.
100% Synthetic would be a good choice.
Check it at each oil change, and replace when dirty.
Depending on how the car is used and the location is very important for this. A car in the city may need a new filter every year or 15,000-30,000 miles. A car in the country will need one less often.
Depending on how much you drive your car should be how often you change your air filter. Sources say you should change it when you go to get your oil changed cause they both last about the same time.
it depends on the car and driver. i drive my Volvo hard, and its turbo charged so i replace the oil every 3000 miles with full synthetic, if its a turbo i would replace it with only full synthetic and at most every 5000 miles. if it is a regular one, any kind of oil will do and change it between 5000 miles and 7500 miles only if you drive very lightly on the car.
