Frequently asked questions

Q. How often should I really change my oil?

 This used to be a simple question and the standard response was every 3,000 miles or 3 months which ever came first. However today, the answer is not as cut and dry. If you are using regular oil the answer has not changed, you should change your oil about every 3,000 miles or 3 months. If on the other hand you are using a synthetic oil, the change interval may be considerable longer. Synthetic oils often have change intervals of 5,000 miles or even more in some cases. You really need to check your owners manual and go by what your car's manufacturer recommends. It is important that you not exceed the recommended change interval for your vehicle as some manufactures have voided warrantees in certain instances where customers have not properly followed their guidelines. provide the following list of links to online manuals.

Q. How often should my car's air filter be replaced?

Dirty Air filterIf your vehicles air filter looks anything like this one, it is time to change your air filter. As with most routine maintenance items your vehicles manufacturer will suggest a change interval. There are a number of factors that can significantly effect the life of a vehicle's air filter. Most of us can understand why driving on dusty unpaved roads would shorten an air filters life but manufactures will call for shorter change intervals in other instances. One of these is very common in the DFW area, driving in heavy traffic on hot days.can result in significantly short functional life of your vehicles air filter. So engine air filters in some instances may need to be changed as often as every 15,000 and in extreme case even short periods. Under good conditional an air filter can last between 30,000 to 45,000 miles. Theair filter clean vs dirty point is there is now way to know if your air filter needs changing without looking. We routinely check customers air filters and one of our technician may suggest changing yours. Normally out technician if he is suggesting a new air filter will show you your current filter. If that is not the cas. please feel free to ask our tech to see your cars air filter before making a decision as to whether or not you want to change it.

Air filters are an important part of your vehicles fuel system but putting off changing one until the your next oil change will usually not case any damage, but do not ignore your engines air filter. In a Department of Energy 2009 study, they found that a dirty/clogged air filter can result in a 6% to 11% drop in fuel economy. That kind of drop can really added to some real money, in a relatively short period of time. Even with todays lower fuels price an 11% drop in fuel econemy does not take long to more then offset the cost of replacing your air filter.

Q. Can Kwik Kar do My Services Without Voiding the Warranty?

Mag mossFederal law — specifically, the Magnuson-Moss Warranty Act of 1975, title 15, chapter 50, section 2301-2312 — prohibits a new car dealer from denying warranty service or implying that warranty service will be voided if servicing or repairs are not performed at the dealership.
This has not stopped a number of auto makers from trying to scare customers into only using there repair and maintenance facilities. Kia for instance issued a technical service bulletin (TSB) issued by Kia that states: “Customer concerns as a result of incorrect oil viscosity or use of aftermarket oil filter should not be treated as a warranty repair and any related damage is not warrantable, nor is changing engine oil and filter to isolate this condition.”
Kia went on to say:

  1. If your Kia is still under the powertrain warranty, considering taking it to the dealer for oil changes. Yes, it probably costs more than the quick-lube store, but you’ll avoid any potential problems with oil- and filter-related warranty claims.
  2. Consider buying Kia-approved oil filters and either using them when you do your own oil changes, or have your mechanic or quick-lube store use the Kia filter and not their own.

In 2013 BMW the owner of Cooper Mini stated in the owners manual for the 3 Series and Coup that “Oil changes should only be performed by a BMW Center.

These statement are clearly not in following with Federal guidlines set forth in , the Magnuson-Moss Warranty Act. The Federal Trade Commission is the governmental organization tasked with enforcing the law. The state the following on their website, "An independent mechanic, a retail chain shop, or even you yourself can do routine maintenance and repairs on your vehicle. In fact, the Magnuson-Moss Warranty Act, which is enforced by the FTC, makes it illegal for manufacturers or dealers to claim that your warranty is void or to deny coverage under your warranty simply because someone other than the dealer did the work. The manufacturer or dealer can, however, require consumers to use select repair facilities if the repair services are provided to consumers free of charge under the warranty."

Q. I am hearing a noise when I apply my breaks, do I need break work?

First off, if you are worried about a noise coming from your breaks, especially a noise you just started hearing it might be a good idea to stop in for a free break inspection. We will be glad to take a look at your brake system and tell you is causing the noise you are hearing. Your brakes are just about the most important safety feature on your vehicle. It is never a good idea to ignore a problem with something as important to the safe operation of a vehicle

There are a number of reasons why your breaks my be making a noise. Very often if you are hearing a noise, especially a noise you are not accustom to hearing you may need break work. If your last break repair was at a place offering free lifetime replacement and a price like $99. These type of deal usually comes with the least expensive brake pads or shoes available, which makes sense considering the cost of the service. The type break pads or shoes used in these offers a typically very hard metallic  pads and shoes. It is not uncommon for these pads and shoes to cause a squeaking noise. They work just fine in stopping your car but they can be noisy and will wear out your disks and drums much faster than the pads and shoes originally found on your car from the manufacturer. This is great for the shop selling the $99 lifetime pads because when you come back the next time you very well may need new rotors (disks) and/or drums.

Often times brake will begin to make noise as the pads get close to being worn out. Some brakes have wear indicators that will cause noise when your brake get close to being worn out. The indicator cause a noise as a warning to the vehicles owner that services is going to be needed soon. If you are hearing a loud squealing or grinding noise it is time to have your breaks checked. Your brakes should really never make a grinding noise. If your brakes are grinding you need to have them inspected immediately.
