PCV Valve: What Is It?

Most St. Thomas drivers know something about preventive maintenance on a vehicle. We know we should routinely replace the oil and wiper blades and other fluids. But have you heard of a PCV valve ? This little car part needs to be replaced regularly or it can cause some serious problems in your vehicle engine.PCV stands for Positive Crankcase Ventilation. The crankcase holds your motor oil and is located at the bottom of your engine.When fuel is burned in your engine, it produces waste gases that are mostly vented out through your exhaust system. But some of these gases push their way past the pistons and into the crankcase. There, these gases can mix with motor oil to produce oil sludge, which can damage vehicle engine parts through corrosion and by clogging engine passages. St. Thomas vehicle owners should be advised that if the engine is running at high speeds, these gases can also cause pressure inside the crankcase to build up. This pressure, in tu ... read more

Breathe Deep With Your Cabin Air Filter

Bad air quality while you're driving around St. Thomas is nothing to sneeze at. But seriously, more and more vehicles these days come equipped with a cabin air filter. Since they're fairly new on the scene, a lot of folks don't know about them yet.These filters clean the air in the passenger compartment, or cabin, of your car or truck. They do the same job as the furnace filter you have at home. They can filter out particles as small as three microns. By contrast, a grain of sand is about 200 microns.So your cabin air filter can clean out dust, pollution, pollen and spores to keep the air in your car nice and clean. And just like your furnace filter, they need to be replaced when they get dirty. Check your owner's manual or ask your service advisor at Gurr Auto, but they typically need to be replaced at around 12,000 to 15,000 miles (19,000-24,000 kilometers).The filter is usually either under the hood or under the dashboard. Some are a little tricky to get to, so you'll wan ... read more

How Your Check Engine Light Works

Have you ever had an experience like this in St. Thomas, Ontario? You drive through the one of those automatic car washes. When you get to the end, where the dryer is blowing, your Check Engine light starts flashing!You fear the worst, but within a block or two, the light stops flashing, but stays on. By the next day, the light is off.You wonder; "What was going on?" Well, it's actually a good lesson in how the Check Engine light works.Your air intake system has a sensor that measures how much air is coming through it. When you went under the high-speed dryer, all that air was blasting past the sensor. Your engine computer was saying, there shouldn't be that much air when the engine is just idling. Something's wrong. Whatever's wrong could cause some serious engine damage.Warning, warning! It flashes the Check Engine light to alert you to take immediate action.It stopped flashing because once you were out from under the dryer, the airflow returned to normal. Now t ... read more

How to Get Better Gas Mileage in St. Thomas

There is no escaping it: things work better when you take care of them. Something most of us in St. Thomas can relate to is our computers.

Tacky or Techie? The Tachometer.

There's a gauge that many vehicles have that says RPM on it.  And there are a lot of people who either don't pay any attention to it or don't even know what it is. Here's why it's a good gauge to know about. It's called a tachometer, and that "RPM" label means it is measuring how many revolutions per minute (RPM) the engine is turning.  Automotive experts know that a vehicle's engine can be damaged if it turns too fast (revving too high) or too slowly ("lugging" the engine). A tachometer (sometimes called a tach) is almost a "must-have" gauge for vehicles with a manual transmission; the driver has to manually change gears; the tach helps the driver know when revolutions are in the optimal range. Some say you don't need a tachometer if you drive a vehicle with an automatic transmission. It's true that most drivers of automatics don't even look at it.  But there are times when paying attention to the tach can help you prevent an expensive repair. Here's a good example.&nbs ... read more

All About Your TPMS in St. Thomas

St. Thomas drivers know that underinflated tires wear out more quickly. Underinflation is also a major cause of tire failure for Ontario auto owners. More flats, blow outs, skids and longer stopping distances are all results of underinflated tires.It's hard for many St. Thomas drivers to tell when a radial tire is underinflated. If your owner’s manual recommends 35 pounds of pressure, your tire is considered significantly under-inflated at 26 pounds. The tire may not look low until it gets below 20 pounds.Uncle Sam to the rescue! A recent U.S. federal law required vehicle manufacturer’s to include a Tire Pressure Monitoring System - or TPMS system - in all vehicles. Many Canadian vehicles have them as well.  The system is a dashboard mounted warning light that goes off if one or more of the tires falls 25% below its pressure recommendations.Obviously, all of this doesn't come free for St. Thomas car owners ... read more

Recommended St. Thomas Service Intervals

Everyone in St. Thomas, Ontario, knows we are advised to go to our St. Thomas dentist twice a year.  Oral-conscious St. Thomas residents have a teeth-cleaning and examination. Once a year, we get x-rays to look for problems that can't be seen with the naked eye. When our dentist is done, he/she tells us what was found – "Everything's fine, see you in six months." Or "You've got a small cavity starting, let's schedule an appointment to take care of it." By the time you leave, you have a plan for addressing any necessary issues.This system works so much better than waiting for a painful problem before going into the dentist. Small problems are fixed before they turn into big problems. And you avoid those huge bills.If St. Thomas folks understand the wisdom of using this system for handling dental care, why do many resist when facing the same system for our vehicle maintenance? Following the vehicle manufacturer's recommended intervals can be confusin ... read more

How to Know When to Change Your Oil at Gurr Auto

Today in the Gurr Auto auto care blog, we're going to talk to St. Thomas drivers about oil change intervals. It seems that as engine technology advances, oil change intervals become longer for Gurr Auto customers. For example, recently four of the world's largest vehicle manufacturer's shortened the published intervals for several of their engine models. They originally published intervals that extended out to a much as 8,000 miles (13,000 kilometers).In real world St. Thomas driving, the oil started to sludge up before the recommended change interval. Oil sludge is a thick jelly-like substance: quite literally petroleum jelly – like Vaseline. This goop was clogging vehicle small engine passages so the oil wouldn't flow to some parts of the engine. This resulted in engine damage. We see it too often at Gurr Auto in St. Thomas.The vehicle manufacturers began to offer an extended warranty to cover sludge damage. But there was a catch: the vehicle owner had to foll ... read more

Tire Tread Depth for St. Thomas, Ontario Drivers

Driving on bald tires is like playing roulette. Though you may be fine today, eventually your luck is going to run out.The Feds don't have any laws for tread depth, but 42 of the states, and all of Canada, do have regulations. They consider 2/32 of an inch to be the minimum legal tread depth. Two other states, including California, consider 1/32 to be the minimum and six states have no standards at all. Call us at Gurr Auto; (just call 519.637.9861) to find out what your requirements are in the St. Thomas, Ontario, area.Since 1968, U.S. law has required that a raised bar be molded across all tires. When tires are worn enough that this bar becomes visible, there's just 2/32 inch/1.6 mm of tread left. But does that older standard give St. Thomas vehicles enough safety?Consider this: Consumer Reports recommends tire replacement when tread reaches 4/32 inch/3.2 mm. And the recommendation is backed by some very compelling studies. Now before we go into the studies, yo ... read more

Differential Service in St. Thomas, Ontario - What You Need to Know

Scratching your head? Don't worry, if you don't know what a differential is – you will in a moment. That fact is that if you drive a car anywhere in St. Thomas, Ontario, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. Some St. Thomas vehicles might even have two or three.Not surprisingly, a differential's job is to compensate for differences; specifically, they're the differences in wheel speed when turning. For instance, imagine taking a corner near your St. Thomas, Ontario, home. Your inside wheel has a shorter distance to travel than the outside wheel as you turn the corner. That means that your outside wheel has to turn faster to keep pace with the inside wheel.The differential allows the wheels to turn at different speeds while still providing power to your vehicle. Without a differential, St. Thomas residents' tires would scrub and hop along the pavement during turns like the early cars ... read more
