Motor Oil?The Synthetic Advantage (Synthetic oil vs Conventional)

You’ve probably already heard that regular oil changes are extremely important for the health of your vehicle’s engine. That’s sound advice.  But what you might not know is when it comes to motor oil, the real thing may not be the best thing for your engine.

There are different types of motor oil:

• Conventional oil, extracted from the ground and refined.
• Synthetic oil, manufactured from high-quality base oils and artificially-made chemical compounds.
• Synthetic oil blend, a mixture of conventional and synthetic oils.

The first thing you need to know is that most new engines require synthetic oil.  If synthetic oil is recommended for your car – you MUST use it.

For the rest, there are many advantages to using synthetic oil over conventional oil.

• Synthetic oil provides better protection for your engine while helping it to perform better.
• Conventional oil breaks down over time, while synthetic oil lasts longer.
• Synthetics can stand higher temperature extremes, both heat, and cold.

Synthetic oil can be a better choice if you live in an extremely hot or cold climate or put a lot of strain on your engine by towing or carrying heavy loads.  It also may be good for older engines that sometimes have a tendency to develop sludge.

Synthetic oil is a more expensive option, but you likely won’t have to have your oil changed as often.  Some synthetics are recommended to last 10,000-15,000 miles/16,000-24,000 km between changes.

You might also consider a synthetic blend that gives you some of the advantages of synthetic oil at a lower cost. Have a talk with your service adviser about recommendations for what will best suit your vehicle and driving habits.

It’s interesting to note that in recent years, more than one out of two vehicle owners are opting for synthetic oil or a synthetic blend when they get their oil changed. Sounds like they’re on to something. In the long run, if you have fewer oil changes with synthetics, you’ll use less oil, a bonus for our environment.

Lean Times (Shocks and Springs)

You may have noticed your vehicle going through lean times.  By that, we mean it's literally leaning to one side.  When you notice that, you should get it checked out at your service facility soon because you could have a serious problem.

Many things can cause a vehicle to lean.  You may have problems with your struts, shocks or springs.  They all work in tandem to make your ride more comfortable.  The struts bear the weight of the vehicle's body, the shock absorbers employ a piston that keeps your tires in contact with the road and controls movement of the vehicle's body.  Springs also absorb impacts from uneven road surfaces.

If these components get stuck, either too high or too low, they cause your vehicle to lean.  That's because that side of the vehicle isn't at the height it is designed to be.  A technician will determine where the problem is.  Outside elements such as moisture plus hard knocks to these components can weaken them, eventually resulting in a failure.  The metal can get so fatigued that it breaks.  Often when one side of a vehicle is too high or too low, your service advisor will advise you to have the other side done as well.  That's because if only one side has new parts installed, it won't be level with the side that has old parts. 

There are a couple of other reasons vehicles can lean.  One is that the suspension can be bent or the chassis twisted, again due to wear and tear by driving on rough roads, over badly maintained railroad tracks or in deep potholes. 

Another reason your vehicle may lean is that the tires and/or wheels aren't all the same size.  Or one side might have drastically over or underinflated tires.  This can be a dangerous condition since the imbalance can affect steering and handling.

Considering what drivers put suspension parts, tires and wheels through, it's not surprising that they can be punished so much that they don't hold up like we want them to.  A level-headed driver will make sure to be driving a level vehicle by making sure these components are maintained in good condition.

Dirty Air Conditioning System

How a Dirty A/C Causes Odors, Bacteria, and Mold

The root cause is usually a combination of moisture, darkness, and debris within the evaporator core, a component located behind your dashboard.

• Moisture Accumulation: As the A/C cools the air, moisture condenses on the cold evaporator coils—similar to how water beads on a cold glass. If this water doesn't drain properly through the exterior drain tube, it creates a stagnant, damp environment.  

   

• Debris & Bacteria: Dust, pollen, and organic matter can bypass or settle on a dirty cabin air filter. When these particles hit the wet evaporator, they rot and provide "food" for bacteria and mold to thrive.

• The Smell: When you turn on the fan, air is forced through this layer of growth, carrying musty or vinegar-like odors directly into the cabin.

How to Prevent A/C Odors

• Dry the System: A few minutes before reaching your destination, turn off the A/C button but leave the fan running. This helps evaporate the moisture on the coils before you park.  

   

• Replace Cabin Air Filters: You should generally replace your cabin air filter every 12,000 to 15,000 miles. A clean filter prevents organic material from reaching the wet components.  

   

• Clear the Intake: Ensure the area at the base of your windshield (the cowl) is free of leaves and debris, as this is where the system pulls in fresh air.

• Check the Drain: If you don't see a small puddle of water under your car after using the A/C on a hot day, your drain tube might be clogged and should be cleared.

Proper Function of a Car A/C

Contrary to popular belief, an A/C system doesn't "create" cold; it removes heat and moisture from the cabin air. It functions as a closed-loop cycle:

QUIET TIME (Listening for Vehicle Problems)

Everybody's got friends like this.  You know, the kind who, the minute they get in their vehicle and turn the key, the sound system is deafening.  They just love to hear that music, sports, news… anything but the sound of the vehicle itself.

And maybe you're that person, too.  Here's something to consider: your sound system might be drowning out some valuable clues that could help you diagnose problems with your vehicle, problems that need to be dealt with. So, turn down the volume and listen for these things:

• A clicking sound when you're braking or turning—You could be missing some parts in your braking system, or it could be damaged. That sound could also signal that components are just plain worn out.
• Rattling under the hood—If it sounds like metal clanking against metal, you could have something serious going on, maybe an overheating engine or your timing needs adjusting. That knocking sound could also be as simple as you've been using lower octane gasoline than is recommended for your engine.  Time to get that checked out.
• A squealing or high-pitched sound coming from the engine compartment. Could be a belt is loose, wearing out, dried out or cracked. A pulley might be failing or a bearing might be on its last legs.  Better to have that fixed now than be stranded somewhere later.

Here’s our Cruz Auto Repair suggestion - set a regular weekly alarm in your smartphone alerting you to listen to your vehicle once a week for five minutes.  Just five minutes without the music or the sports show or public radio… whatever your taste is. You can even use your smartphone to record any noise you might be hearing.  Between that and your description to your service advisor, a Cruz Auto Repair technician should be able to diagnose the source of the noise and get your vehicle sounding healthy again. Do it before that noise turns into the sound of a serious problem. 

Who knew a little quiet time could be so useful?

No Charge (Why Won?t My Battery Hold a Charge?)

When your vehicle’s battery is dead, it leaves you with that horrible, helpless feeling.  A dead battery means it won’t hold a charge, and there are several reasons it won’t.

One is age.  Batteries have chemical and electrical systems in them that create power, and as time goes by, they won’t work well anymore.  They may have been degraded by exposure to extreme temperatures, both hot and cold. Batteries have a code on them that can tell you when they were manufactured.

Another reason your battery won’t hold a charge is corrosion on the terminals, the metal posts where your battery cables are connected.  A chemical reaction between the battery’s acid and air creates a salty moisture that can corrode those terminals.  

If your vehicle’s alternator is not working properly, it won’t charge your battery as it is designed to, and the battery may lose its charge more quickly than it should. Another possibility is there might be an electrical component that’s staying on when you turn your vehicle off, and it may slowly drain the battery so much that there won’t be enough power to start your vehicle.  

When you notice any of these things, bring your vehicle in so a technician can evaluate what’s causing the problems.  We will give your electrical system a thorough inspection and run tests that can tell the health of the battery and other components.  You may be able to avoid problems by having us evaluate your electrical system regularly as part of a periodic maintenance schedule.

Bad Vibes

Your vehicle has a way of letting you know when something's wrong. Consider a vibrating steering wheel. It certainly didn't do that when it was new, so that shake is trying to tell you something.

There are a few things that can cause your steering wheel to vibrate as you drive down the road.  One of the most common is out-of-balance tires.  You may not only feel that wobble in your steering wheel, you might also feel it in the tires.  Sometimes it's not there when you're driving at lower speeds through residential areas, and sometimes it starts when you hit highway speeds. 

So what is tire balance anyway?  Well, you have a rubber tire that fits around a metal wheel.  It should have the same weight all the way around.  If it doesn't, it will start getting the shakes.  Ever load your washing machine so that all the clothes are at one side of that drum that spins?  When it hits the spin cycle, it can throw that washer against the wall. 

That's the same thing that's happening with an out-of-balance tire/wheel combination.  A technician has special equipment to figure out where to put small weights on the wheel to get things back in balance again.  But it could be that you hit a pothole some time ago and bent the rim.  Or your tire isn't as round and even as it once was.  That could be due to age, damage or wear and tear. The technician will know and offer you options.

Another possibility for that vibrating wheel is a faulty brake, such as warped rotors or a sticky caliper.  All of these issues can be evaluated as part of regular, routine maintenance with us.  There are many things that cause vibrations in your wheels.  But you don't want any bad vibes when it comes to your vehicle. 

Free Money (Almost) (Fuel Saving Tips)

You spend a lot of money on a vehicle, probably the most money you'll spend on anything except a house.  But the spending doesn't stop after you've bought it.  It goes into things like insurance, repairs and fuel.  One good piece of news is that you can cut down the amount you spend on fuel if you follow a few tips.

Keep your speed under 50 mph/80 kph.  Anything over that and your fuel economy will go down quickly the faster you go.  Sure, you can legally drive  faster than that, but practice this one tip and it can save you from 7%-14% on fuel.

Use cruise control.  The steady speed increases fuel economy by avoiding unnecessary braking and accelerating. 

If your vehicle is carrying unnecessary weight, unload it.  If you can save 100 pounds/45 kilograms, it can save you 1% of your fuel. 

Don't idle.  Let's say you're sitting in a parking lot with your engine running for 10 seconds.  Any more and you're wasting fuel.  Turn off your engine and start it when you have to get going.  You may have noticed that many newer vehicles automatically turn the engine off when the vehicle stops.

Avoid using a roof rack.  A cargo box strapped on the top of your vehicle can reduce your fuel economy by 2%-8% in city driving, by 6%-17% on the highway and by 10%-25% at highway speeds over 65 mph/105 mph.

Also, if you have roof rails on your vehicle with crossbars, you can save 1% of fuel simply by storing them somewhere else.  Some vehicles like Chrysler's Pacifica minivan allow you to store the crossbars inside the roof rails to reduce drag.

Keep tires at their recommended inflation.  It can save you 3% of your fuel bill.

Use the right motor oil for your vehicle.  Using the wrong kind can cost you 1%-2% more money on fuel.

Sure, many of those savings are small on their own.  But add them up and you'd be surprised at how much you can save.  Also, keep in mind that a well maintained vehicle will also save you fuel, so make regular maintenance trips to your vehicle service facility.

You Are the Fluid Detective! (Leaking Fluids)

When you see some liquid sitting underneath your vehicle, your mind starts churning.  Is that normal? Is that something serious, or did I just spill my drink? Here’s a quick list of what those fluids look, smell and feel like, as well as what they might be. No, we don’t recommend you taste them to verify.

   •    Clear and underneath your air conditioner or under the end of your tailpipe. It’s likely something as simple as condensed water.  This probably doesn’t need immediate attention, but you should keep checking periodically.
   •    Oily, brown, golden or black.  That could be the sign of engine oil leaking.  Oil may also smell if it has been leaking on metal and burning.  This is one you should have checked out fairly quickly.
   •    Green, blue, red, yellow, purple or orange and watery under the engine.  Smells sweet.  May be coolant (antifreeze) and a sign of a leaking radiator, hose or clamp.  Also, could mean your water pump is shot or radiator is broken or cracked.  The more that’s there, the more important it is for us to check it out soon.
   •    Yellow, slippery and smells a little foul.  Could be brake fluid. This is one that you should bring to us quickly to have us inspect.
   •    Red or pinkish and collects under the engine or middle of your vehicle.  Could be power steering fluid.  Here’s another one that should be checked by a professional soon.
   •    Red or brown liquid from around your transmission or between your radiator and the transmission, smells sweet.  You might smell burning from around your engine area, too.  Might be transmission fluid.  Another one where it’s important to have a pro look at it soon.  

Your eyes and nose can be helpful to spotting things that need attention on your vehicle.  When in doubt, head on over to see us so a technician can check it out.  Taking care of it sooner rather than later could save you an expensive repair down the road.

Don't Stack the Mat

In the sloppy cold weather months, you might be tempted to pick up an all-weather mat and throw it on top of the mats you already have in your vehicle. After all, double protection is better, right? In this case, wrong. Here's why.

It's important to keep the accelerator and brake pedals clear so they can function the way they are supposed to. Stacking mats in the driver's side footwell can make them sit up too high on the floor. That can, in turn, jam your accelerator pedal forward, causing your vehicle to unintentionally speed up; it may get stuck in that position. Same thing applies to the brake pedal. The mats can get caught underneath it and prevent you from stopping.

Here are some other good practices when it comes to mats. It's best to get those designed for your vehicle. They are shaped to fit your specific car, truck, van or SUV. Ill-fitting mats can have the same untended consequences as stacked mats.

Good mats will have either a Velcro-type fastener on the back of them or a hook that fits into a hole in the mat. That way, the mat stays affixed to the floor so it doesn't slip and cause problems.

One more thing to keep in mind. If you have objects rolling around your vehicle, let's say under the driver's seat, just think about what happens when you jam on the brake. That object is thrown forward and can get caught in a pedal. You might find the accelerator stuck or the brake pedal inoperative.

Your service advisor at Cruz Auto Repair can recommend the right mat for your vehicle. The right mat may save your carpeting, the wrong one may cost you an accident.
