Do Synthetic Oils Require A Special Filter

Synthetic oils are promoted by manufacturers of motor oils as having longer life. In fact, makers of many newer cars are now specifying that synthetic oils be used, and many more car owners are opting to use synthetic oil in their cars and SUVs. Yet, when it’s time to change the oil, many car owners are unsure as to whether they need a special oil filter with synthetic oils.

“All of the oil filters we market today are fully compatible with synthetic oils,” said Kevin O’Dowd, Director of Marketing & Communications, for MANN+HUMMEL Purolator Filters, manufacturer and supplier of top quality oil filters to the North American aftermarket.

“Our PureONE and Purolator Classic include media and other materials that are engineered to work with all synthetic oils marketed in North America today. If a motorist replaces the oil and filter on their vehicle every 3,000 miles recommended by many in the industry, they can use any of our Purolator filters with confidence,” O’Dowd said.

However, if a motorist’s intention is to stretch out the oil change interval to take advantage of the benefits promised by the suppliers of synthetic engine oils, then it’s important to select an oil filter that matches and offers expanded ‘capacity’ and ‘efficiency’ to safely capture and hold the additional contaminants that will accumulate over longer time periods.

Enter Purolator Synthetic.

Based on cutting-edge technology, the recently introduced Purolator Synthetic oil filter family has been designed for longevity from the ground up. It utilizes 100 percent synthetic media with pleat support technology containing wire backing. Purolator Synthetic has substantially greater ability than conventional oil filters to capture and safely hold more contaminants generated over the extended life of synthetic oils without getting clogged. It is especially designed to work well on today’s high-tech engines, O’Dowd said.

Purolator Synthetic features 99 percent ‘efficiency’ which means that it can capture and safely hold 99 percent of particulates 25 microns in size or larger. A micron is a millionth of a meter.

It is this extraordinary combination of capacity and efficiency, along with innovative design technology, that maintains the integrity of the media for extended periods of time.

“In addition, all Purolator oil filters – PureOne, Classic, and Synthetic, incorporate materials that are fully compatible with all synthetic oils that meet the API and SAE standards as specified by virtually all automakers,” explained O’Dowd. “We have done extensive testing to assure that all of our canisters, sealing rings, bypass valves, anti-drainback valves, binders, and other materials are unaffected by the chemistry in synthetic oils. So motorists can choose any of our oil filters based on their needs and budgets,” he said.

According to O’Dowd, “All of these features make Purolator Synthetic a 10,000-mile filter for motorists that are using synthetic motor oils in their vehicles, and PureOne and Classic appropriate choices for any car,” he said.

Air Conditioning Checklist

 

Hours spent in a hot, stifling vehicle can spoil a weekend getaway or vacation. Conducting a periodic under-hood inspection may help you spot air conditioning problems before they spoil your trip.

Here’s what to look for: Note: Always be extremely careful any time you’re under the hood while the engine is running. Stay away from all rotating components with your hands, clothing, and hair, and always wear eye protection around a running engine.

1. Are A/C component mounting bolts in place and tightly secured?

2. Are caps installed on the A/C system service ports? This keeps out dirt, and also provides a seal for refrigerant.

3. With the engine running, does the compressor clutch engage when the A/C is switched on? If it doesn’t, this usually indicates a low (or empty) refrigerant condition, or an electrical problem. Also, listen for rapid clicking or cycling noises at the compressor when the A/C is switched on. If this is happening, it could also indicate low refrigerant or some other problems. Have it checked by your service technician. (Note: Some A/C systems prevent compressor clutch engagement in low temperatures, typically at or below 40° F.)

4. With the engine running and the A/C switched off, listen for knocking or rumbling sounds in the vicinity of the compressor. These could indicate a failing compressor clutch, and/or loose mounting hardware.

5. Check all belts for cracks, wear, and glazing. Have them replaced at the first sign of any of these conditions. Also, check for belts that vibrate while the engine is running and the A/C is on. This may indicate a belt that needs to be tightened, or a defective automatic belt tensioner.

6. Examine all A/C and cooling system hoses for cuts, abrasion, weak spots, and signs of leakage. Leakage from A/C system hoses is often indicated by an accumulation of dirt and oil, particularly at connections and fittings.

Could The Water Has Damaged Your Car

With heavy rain pounding many parts of the country, there’s a good chance that you’ll drive through high water that could damage your vehicle. Even though your vehicle may not have been flooded or completely covered in water, the Car Care Council recommends that motorists follow these guidelines to check for damage due to water intrusion or contamination:

  • Check interior carpets, upholstery and door and trim panels for dampness. If they are wet, then the vehicle will need professional attention. If you simply let the carpet dry, it will quickly grow mildew and give off nasty odors. Seat brackets, motors and modules should also be checked for rust and proper operation.
  • Pull the engine oil and transmission fluid dipsticks and differential plug. If the fluid appears milky, diluted, is no longer its original color or is beige in color, then it is likely the pans contain water. The vehicle should be towed to your ASE-certified technician or repair shop. Driving the vehicle with water present may damage the internal parts and require extensive overhaul or repairs. The council reminds motorists that some new synthetic differential fluids may appear to be milky but are not water contaminated. When in doubt, a professional automotive technician should make the evaluation.
  • Check the air filter for water. If it is wet, replace the air filter and change the oil.
  • Check the undercarriage, bumpers, radiator area and frame for mud, grass, dirt, debris and rust. If any of these are present, the vehicle should be washed and cleaned as soon as possible.
  • Have the brake system checked by a professional automotive technician.
  • Check the exterior lights for moisture and water. Replace headlights and bulbs that contain water.
  • Listen for abnormal noises while the engine is running. Make a note of where the noise is coming from and take the vehicle to a professional automotive technician as soon as possible. Pay particular attention to the alternator, serpentine belt, starter, power steering unit, air conditioner and wheel bearings.
  • Inspect the suspension joints and lubricate as necessary. Many newer vehicles are lubricated at the factory for life; however, these joints should be checked for rust.

“It all comes down to how much water the vehicle took in and where it reached,” said Rich White, executive director, Car Care Council. “By being car care aware and following these simple guidelines, you can help minimize the potential for damage to your vehicle.”

Automatic Transmission Stop Leak

The automatic transmission is a pretty incredible device when you get a chance to look inside of it.  The technology that is needed to eliminate manual shift transmission needs to have electronics and hydraulics to work in unity.  The transmission fluid flows throughout the whole transmission like oil in an engine.  It cleans, lubricates, cools and actuates the different assemblies that cause the automatic shifting to occur for thousands of miles. Rubber seals, gaskets, shift valves and clutches all must perform their jobs flawlessly or the automatic transmission is useless.

 

Automatic transmission fluid change intervals are much longer than that of engine oil since the fluid is not exposed to the high heat and combustion gases that engine oil is constantly dealing with.  The transmission fluid does break down due to the physical stress placed on it during normal operation.  As it wears it can no longer protect the seals, clutches and such that it is supposed to protect.  The detergents will weaken, allowing a varnish type material to start coating the hard metal parts and cylinders inside the unit.  Seals that are in place to control the flow of the fluid or lock up clutches start to harden with age, allowing fluid to leak by not applying the proper forces needed for good shifts.

 

When the transmission is serviced in many of today’s vehicles, the main transmission pan is dropped, allowing for some of the transmission fluid to come out of the unit.  This can amount to four or six quarts of fluid leaving another four or more quarts still remaining in the transmission.  So only about half of the fluid may really be changed normally during this service.

 

The detergents and additives in the new transmission oil will go to work on the build-up of varnish and hardened seals.  Adding K&W Trans-X® Automatic Transmission Stop Leak to the fluid during this normal service will further recondition the surfaces and seals inside the transmission.  This will add miles to the life of the transmission if done at each service interval.

 

If an automatic transmission exhibits any symptoms such as soft and sloppy shifts, shifts that are very firm and harsh, or slow engagement when placed in drive or reverse these can all be the result of a transmission’s normal wear.  As long as there are no grinding noises or other hard part issues, K&W TRANS-X added to the transmission can revert the shifts back to their normal condition possibly eliminating or delaying expensive repairs.  K&W TRANS-X is an inexpensive fix that may save lots of money when an older transmission is starting to fail.

 

Because of the construction of the automatic transmission out of many individual parts, leaks can also occur at many different locations.  Many seals and gaskets are used in the building of the transmission.  As they wear and age, leaking can occur.  If the leakage is great enough to lower the fluid level substantially, erratic transmission operation will occur with major internal damage to follow.

Adding K&W TRANS-X during normal service and when needed can help prevent these leaks from occurring and even seal some of the seeping ones.
