Auto and car tune-ups are one of the most grossly overpriced scams going today. If your auto or car is a late 80s model or above, you really only need a simple periodic maintenance tune-up. Otherwise, you’re wasting money paying for old-fashioned “complete tune-up.”
You see, before the late 80’s, vehicles needed complete tune-ups as often as every 6,000 miles. There weren’t many vehicles that could be driven more than 12,000 miles before noticeable performance deterioration.
So, over the years, motorists became conditioned to the idea of 6 month or annual tune-ups, that is, new points, plugs, condenser, ignition timing adjustment, new air and fuel filters, carburator adjustment, and sometimes the replacement of distributor cap and rotor.
Well back in the 70’s, manufacturers stopped making vehicles with points and condensers. Then in the 80’s, munufacturers started producing vehicles with computerized electronic ignitions, followed by computerized distributorless ignition systems.
So what’s left to tune? Vehicles built since the early 80’s can not be tuned up in the traditional sense. As a matter of fact, if you look in your engine compartment, you’ll see a label clearly advising you that no tune-up service is required. You will also find the same advisory in your owner’s manuals…which few people read.
If people would read this information in the engine compartments and owner’s manuals, they’d see that the only routine ignition “tune-up” work needed is spark plug and air filter replacement every 30,000 miles or so. This is called a basic maintenance tune-up.
Folks in the auto and car repair industry are not anxious to educate motorists about these facts. However, if you read the fine print of tune-up advertisements, you’ll notice they say “replace spark plugs, check all wires, check all emission hoses, check timing, check this, check that; check…, check…, check.” Lots of checking, but no real work.
There is no carburator to adjust, and fuel injection systems are largely nonadjustable. So all you really need is a basic maintenance tune-up which should be done according to the schedule in your owner’s manual, usually every 30,000 miles, not anually. If you’re making the mistake of getting so-called 6-month or annual tune-ups on a computer-controlled fuel-injected engine, you’re spending a lot of money for some new spark plugs and maybe a couple of new filters.
However, this doesn’t mean that your vehicle will not require periodic ignition-system or fuel-system work. If your vehicle doesn’t run properly, a basic maintenance tune-up probably will not correct the problem. Your vehicle will need computerized diagnosis of the engine management systems.
Many shops still mistakenly call this kind of work tune-up service, even though it involves much more than a tune-up and costs a lot more.
As a general rule, you shouldn’t pay for basic maintenance tune-up unless your vehicle calls for one according to the maintenance schedule in your owner’s manual. If your vehicle is not running properly, and it’s not scheduled for a maintenance tune-up, ask for diagnosis of the engine management systems. Sure, this costs more than a tune-up, but you’ll save the money you would have spent for unnecessary tune-up work.
A complete engine diagnosis can reveal a variety of problems responsible for a poorly running engine.
Bottom line here is to only pay for what you really need.
Do you fully trust the folks who you take your vehicle to for work? If you’re like most people, you don’t. So take a look at carrepairscams/mechanic by Clicking Here. You’re in for a real eye-opener.
