Thoughtful Gifts for the Winter Driver

Posted July 27, 2025 3:57 AM

You may be one of those romantics who don't like giving (or getting) practical gifts for special occasions.  Just wait until one of those gifts helps you out of a big predicament in cold weather, and you realize that practical gifts can be life savers.

Here are a few things you may give the cold-weather driver in your life—or suggest to someone else to give you!

  • A portable air compressor.  If you've ever had a flat and you can't imagine trying to change a tire on a snowy, winter day, this may just get your tire pumped up enough to drive over to the repair facility.  Some are fancy and pricey, some are only a few bucks.  They plug into the cigarette lighter/12v outlet and will take a few minutes to pump up your tire. But it could save you a tow.
  • Portable jump starter. These are relatively small power units (they easily fit in a car trunk) that can jump start your vehicle that has a dead battery.  Some even have an air compressor built in.  If you've ever tried to use conventional jumper cables in freezing weather, they can be stiff and hard to manage.  Really handy when there are no other people or vehicles around and you need a jump.
  • Flares.  When bad winter weather reduces visibility to dangerously short distances, flares can make the difference between someone seeing you broken down at the side of the road and them ramming into you. Flares put out far more light than nearly every other warning device; just ask law enforcement officers who carry flares in their patrol vehicles. 
  • A good tire gauge.  Winter is when temperatures plunge.  When the temperature drops, so does your tire pressure, so it's important to check your air pressure properly and accurately so you don't wind up with one or more deflated (and flat) tires.  The proper time to check pressure is in the morning, before you hit the road and your tires heat up.  Properly inflated tires are important for safe traction, especially during winter.
  • Kitty litter.  The lowest-tech gift of all.  Keep a bag in your vehicle and it can provide much needed traction if you get stuck in the snow.

Steer Me Right! (Failing Power Steering Hose)

Posted July 20, 2025 4:15 AM

Most drivers love how easy it is to turn their vehicles, and they have power steering to thank.  Engineers have figured out a way to take some of your engine's power to help you turn. Without it, steering can be quite a chore.  New power systems are electric, but there are still plenty of the older hydraulic power steering systems out there, and it's wise to keep them working the way they should so you don't find yourself stranded without power steering.

Those hydraulic power systems use a fluid under pressure that is pumped to a device that helps you turn your wheels more easily.  It's that pressure that presents the challenge.  After your vehicle's seen a few years on the road, you may find your steering isn't quite as easy as it was.  You may hear a groaning or humming sound when you turn. 

One component that can fail is the pressure hose that carries that fluid from the power steering pump to that turning assist mechanism.  The hose is made of rubber and can leak, crack, get damaged by heat and debris or just get too old.  If yours is ten years old or older, it's likely getting close to the end of its life.

If you think you can just wait until it fails completely, think of these possible consequences.  If the hose or a coupling fails, power steering fluid can blow all over the hot engine.  That fluid is flammable and can start a fire.  Or if you've been driving for a few weeks with low power steering fluid, that could ruin your power steering pump. Replacing the pump is an extra expense you can probably  live without.

A technician will replace the necessary parts and make sure air and contaminants are bled or flushed from the system.  Then, he or she will check for leaks.  Just think how important a properly working power steering system is for safe operation of your vehicle.  Make sure you keep yours in top shape for your safety's sake and the safety of others on the road around you.

Giving CV Joints the Boot! (CV Joint and Boot Replacement)

Posted July 13, 2025 4:24 AM

Ever wonder how your vehicle’s transmission is connected to your wheels? After all, when you hit a pothole or some other uneven part of a road’s surface, there has to be something that can maintain the connection between the transmission and the wheel yet keep everything moving at the same speed. 

That very cool device is called a CV joint, a kind of driveshaft running to each wheel.  The CV stands for constant velocity because it keeps the drive wheels moving at a constant speed (velocity).  They’re used mostly on front-wheel drive vehicles but also in rear-wheel and all-wheel drive vehicles.

The joints move up and down and adjust to bumpy surfaces.  Plus, they are covered in a rubber boot which protects them from road debris and also holds lubrication in.  There’s a CV joint and boot on the transmission side and one on the wheel side.  Unfortunately, the spot that usually fails first is that rubber protective cover (the boot).  After a lot of wear, tear, bumps, road hazards, heat, and you name it, the rubber rips and the lubrication leaks out.  At that point, it must be replaced. 

Here are signs to tell if your CV joint is bad.

  • Your vehicle is pulling to one side as a wheel loses power or you feel a vibration while driving.
  • You see grease on the inside or edge of your tires.  
  • Your front tires won’t point in the same direction.
  • You hear grinding or clicking when you turn.

Sometimes if a broken boot early is caught early, a technician can pack in new grease and replace just the boot.  But if the lubrication has leaked out and the joint is already wearing badly, the CV and boot both have to be replaced.  Give your vehicle the boot (as in a new boot) and CV joint, and you’ll be back on the road to your next destination.

Oil's Well That Ends Well (Oil Change Grades and Weight)

Posted July 6, 2025 3:52 AM

Changing your oil regularly is one of the most important things you can do to keep your vehicle running well.  And knowing the right type of oil to use is also very important. 

Engine oil is classified by weight, but it doesn't refer to how much the oil would weigh if you put it on a scale.  It refers to viscosity, or how easily the oil flows through the engine.  Most engines operate normally at around 210°F/99°C.  The viscosity, or weight, is assigned a number by how well it flows at that temperature.  The lower the number, the more freely it flows. 

Most vehicle engines use what's called a multigrade oil which behaves differently in different temperatures. Multigrade oils have a "W" in their viscosity number that you may have seen on a bottle of oil, something like 5W30.  The W stands for winter and shows how freely it flows in colder temperatures.

That means a 5W30 oil will behave like a 5 weight oil in lower temperatures (less viscous or thinner) and a 30 weight oil in warmer temperatures (more viscous or thicker).  That's important on a cold day because the oil needs to behave like a thinner oil when you start your engine since it need to lubricate engine components immediately to protect the metal components. Then as the engine warms up, it behaves like a thicker oil to prevent friction among those parts.  Pretty neat trick, right?

The type of oil you use can differ depending on what type of climate you operate your vehicle in and how your vehicle is used (carrying big loads, towing, etc.). Your owner's manual contains several different recommendations based on these factors.  Your service advisor can recommend the right oil for your needs.  Like Shakespeare said, "Oil's well that ends well."

Excellent work. Josh always does all the maintenance for my Porsche, VW Taureg, and Subi Outback. I can always count on him doing what is needed and never trying to upcharge me for work that is not needed.

Took our Acura RDX in for brake service today. The staff at McLearen Shell did an excellent job, replacing the front discs & rotors. They advised that the rear pads still had 50% material remaining. Have had a variety of automobiles serviced at this service station over the last 25 years and there service remains outstanding and very reasonably priced. Highly recommended.

Great team at McLearen Shell, have regularly changed out brakes, bulbs, oil, valve cover gasket, spark plugs, etc. on a 1998 Gen 4 Camry LE for the past three years. Trustworthy, professional and they know these older still-running vehicles. Always respectful to Ladies interested in vehicle mechanical function and maintenance as well
