should i do a tune up even if i dont need one?

Question

i 100k now and ive never done a tune up
car starts and runs fine
i feel like its a waste money to do a tune up

Answer 1

You should look at the manual and do what is recommended by the manufacturer.

Answer 2

It's not a waste of time or money! Over time, performance and economy will slowly deteriorate. You never notice this since the change from day to day and mile to mile is so slight.

If you don't do the tuneup as scheduled you risk major damage to your vehicle. The plugs will start misfiring eventually. This will cause unburned fuel to be dumped into the exhaust. When this hits the catalytic convertor it will cause it to overheat and will quickly destroy it. An overheated cat can also start a fire.

Many modern vehicles have a very long tuneup interval. The old 10k - 20k mile tuneup is long dead; many only require tuneups at 100k mile intervals. These extended tuneup intervals make it even more important that they be done as scheduled by the manufacturer.

You'll probably be pleasantly surprised at the improvement in performance and economy when you do the tuneup.

One more thought. If your car has a timing belt, that typically needs to be changed between 60k and 80k miles. If you have not changed it by 100k, every mile is a borrowed mile. The belt WILL break eventually and most engines will suffer severe damage or even be destroyed by a broken timing belt.

Answer 3

The old fashioned tune ups that you would have to do on a 1960s era engine are dead. There's no carb to adjust the idle mixture, no breaker points to file and gap, and half the time you can't even adjust the spark timing, not that the solid state electronics that control it on a modern car ever wear out.

However, there are other types of routine maintenance that you shouldn't neglect. I'm sure you have been doing oil changes. Spark plugs still wear out and need replacing. Same with the spark plug wires. There's a few other things that may need attention - the PCV valve, air filters, and the like. If you've been keeping up with the correct scheduled maintenance, everything should be all right.

Answer 4

Change the spark plugs and check the air, fuel and cabin air filter if you have one. Spark plugs should never stay in a car more than 30 or 40 thousand miles. Also, check the oxygen sensors, they probably need to be changed out. They should be done at 40,000 to 60,000 miles, check your service manual or dealer. This will save you money at the pump.

Answer 5

If you've got 100k, then yea a tune up is a good idea. Unless you are a mechanic and KNOW your ok, Or so in tune with all the thousand of parts on your car and they are all saying "we are all fine please don't tune us up!" I strongly suggest you think of your future driving days and haul Bessie's butt to the shop.

Answer 6

waiting for something to break will cost you more money then to do whats called "preventative maintenance"..They even say keeping up on all of your maintenance on the GM fine quality 3.4L engine can prevent the onset of the lower intake leak..
Remember the old adage ..pay a little now ..or a whole lot later..

Answer 7

If you bought the car new yes.
used how many miles have you put on it? also city or expressway?
Even if you do not think it needs a tuneup You get one you could see a jump in gas mileage and performance.

Answer 8

Its called preventive maintenance. The more you do preventive maintenance, the better longer your car lasts. I've had several vehicles and had all last well over 100,000 miles for that very reason.

Answer 9

If u mean a service then yes u should .....

serving a car basically help maintain performance so sure its working fine now but its always best to be pre-active in these things ....

Answer 10

There's an old saying that goes like this:

"An ounce of prevention is worth a pound of cure."

If you avoid a problem before it happens, you'll save a lot more money.

I recommend it!!
