Car Care Tips to Keep You On the Road

1. Change the oil at regular intervals.
We can't overstate how important oil is to your engine. Oil lubricates and cools. Oil pressure and flow control many key engine operations. To do its many jobs well, oil needs to be clean. But over time oil gets dirty and degrades. That's why you need to change it regularly. Tiny particles of dirt and metal fragments build up, which can cause engine wear. How? Particles rub like sandpaper on engine parts. Also, oil travels through narrow passages inside the engine and these can clog up, starving the engine of needed lubrication.

Dirty oil can lead to

  • Increased engine wear
  • Shorter engine life
  • Lower gas mileage
  • Poor running
  • Loss of power
Low or insufficient oil can lead to
  • Engine damage
  • A potentially damaging increase in engine heat
  • An engine that smokes
  • Damage to expensive internal engine components
  • Engine failure
Some manufacturers recommend changing the oil every 10,000 or even 15,000 miles, but this is for "ideal driving conditions." If you can find ideal conditions in Colorado, we'd like to see them. In fact, mountain driving is actually considered "extreme."

Given our experience over decades of servicing cars in Colorado, we recommend changing the oil every 5,000 to 7,500 miles. Regular, more frequent oil changes will catch problems sooner and extend the life of your engine.

It's important to know that all oil isn't created equal. At Andersen's, we always use the oil specified by the manufacturer for your car. Today's highly tuned engines need oil that's designed to handle specific conditions. Generic oil that doesn't meet your car manufacturer's specs won't do the job.

Our advice: change the oil every 5,000 to 7,500 miles with oil that meets manufacturer's specs.

2. Change the oil filter at regular intervals along with the oil.
Oil is your engine's defense against heat and wear. The oil filter's job is to protect the oil. Conditions inside your engine are hot and dirty. Dirt from the air, byproducts of combustion and even tiny bits of metal as the engine wears work their way inside, accumulating in the oil over time. The oil filter sieves out this muck but it eventually clogs up. A clogged oil filter also impedes oil flow. If you keep driving with a clogged filter, the filter can actually rip apart and pieces of it can get in the engine, causing a whopper of a problem.

Oil filters aren't all the same and a generic filter likely isn't designed to meet your particular car's needs. At Andersen's, we always use the oil filter specified by the manufacturer.

Our advice: change the oil filter using the OEM filter every time you change the oil at intervals of 5,000 to 7,500 miles.

3. Pay attention to your Check Engine light.
Here's what your mechanic wants you to know about that pesky Check Engine light (aka Service Engine Soon): pay attention to it but don't freak out. Technically, that light is a message to you from your car's emissions control system. It's designed to alert you if the engine exceeds 1.5 times the emissions of the Federal tailpipe standards. There are hundreds of possible factors that will trigger it. If it turns on, more likely than not, you're fine to drive the car and it's not an emergency. But do get it checked out as soon as you can.

Our advice: If your Check Engine light comes on, it's trying to tell you something important. Pay attention to it and get your car in soon.

4. Learn how to read your Check Engine light.
Your 21st-century car is full of computers and computerized sensors. They make things happen and they monitor engine and other systems operations for problems. If your house had a "Check House" light, it might turn on if somebody left the refrigerator door open. You'd want to know if food was spoiling, right? Same with the Check Engine light. It's telling you that something needs attention. Here's how to read its messages:

1) The Check Engine light is flashing. Is the car also running poorly? This could be an "ignition misfire." You can drive your car gently but we recommend you get it in as soon as possible.

2) The Check Engine light came on but went off after a while. The engine computer monitors itself - if the computer gets a reading on an operating parameter it doesn't expect it will turn on the light. If the unusual reading doesn't persist, the computer may decide to turn the light off again. We can tell you what the computer found by reading "the code" for you the next time you're and advise you what to do about it.

3) The light stays on but the car seems to run fine. Again, your car is alerting you to a potential problem but it likely isn't an emergency. Get your car in within a few days when it's convenient and we'll check it out.

Our advice: if your Check Engine comes on, take note of what's happening. Get your car in as soon as you can and we'll get to the bottom of it.

5. Keep an eye on tire condition and tire wear.
It goes without saying that tires are what's between you, your passengers and the road. A flat tire can strand you. A worn tire or one that's too low can actually affect handling. A tire blow-out while you're driving can cause an accident. Avoid tire trouble with a quick walk around now and then. Here are some things to watch for:

  • Is the tread worn? You can perform the "penny" or the "quarter" test to see how your tread is holding up (advice varies). You want to have a good amount of tread and you shouldn't be able to see the top of Lincoln's or Washington's head. Or, look for the "tire wear bars" -- horizontal rubber lines -- in the tread. If the tread is close to the same level as the bars or even with it, you need new tires.
  • Are any tires low? A low tire will actually look flatter than the others and might even bulge out to the sides. Use a tire gauge to check tire pressure (PSI). You can top off the air in your tires but be careful not to overinflate. TIP: manufacturer's PSI numbers for your car are located inside driver's door on the pillar or inside the gas cap flap.
  • Do you see any cracks in the sidewalls? Cracks are signs of a badly worn tire, as are cords or other material showing through where rubber should be. TIP: tires have a date code on the sidewalls (like the "born on" date code for beer). For instance, a tire with a code of 5017 was made in the 50th week of the year 2017. Tires should be replaced at age 7 regardless of appearance.
Our advice: Do a quick walk-around periodically and look at your tires. Top off the air if needed but make sure you follow manufacturer's specs for tire pressure (PSI). If you see signs of wear, get your car in so we can advise you on whether it's time to replace them.

6. Don't overlook the other liquids in your car.
Oil isn't the only liquid in your car that needs attention. There's also transmission oil, coolant (aka antifreeze), power-steering fluid, brake fluid and washer fluid. Unless you're mechanically inclined, the only one we'd recommend dealing with yourself is washer fluid. Stop by any time and we'll be happy to show you how. The other liquids should be checked regularly as part of periodic maintenance by professionals but here are a few things to know:

  • If you see a red or clear oily liquid on your garage floor, it's likely transmission oil. Get your car in right away to fix that leak.
  • Engine oil is gold or black. That's likely another leak you'll want to get fixed right away.
  • Coolant can be bright green, pink or blue and often has a peculiar sweet smell. Insufficient coolant can cause your engine to overheat. Get it checked if you detect it.
  • Transmission oil is highly specialized these days and should only be replaced with oil specified by the manufacturer. Some transmissions have service intervals that include a filter change. Quick lube places aren't really geared up for the procedures required for checking or topping up transmission oil, so we don't recommend them.
  • Manufacturers specify a particular coolant for your car. Chemical makeup of coolant is specific and can affect hoses and seals in the engine. The coolant for some cars, like Volkswagen, can't be mixed with other types. We don't recommend using a "so-called" universal coolant unless it's an emergency.
Our advice: Have all the important fluids in your car checked by professionals as part of your scheduled maintenance. Drips of oily fluids on your garage floor could be signs of a leak. Get those fixed right away.

7. Going somewhere? Do the weekend trip walk-around.
Before you pack the car and head out for a getaway, do yourself and your passengers a favor and give your car a quick once-over:

  • Check the oil level.
  • Check and fill washer fluid.
  • Check the wiper blades.
  • Look at the tires - make sure none are low.
  • Check the spare tire. Make sure there's air in it.
  • Start the car and check the headlights and taillights.
If you're going on a longer road trip, we recommend Andersen's Trip Check. We'll check off the items above and more, top off the fluids and let you know if there's something that needs attention before you go.

Our advice: For a happy trip, make doing the "weekend trip walk-around" part of your pre-trip ritual. Oh, and don't forget to pack some water, the sun screen and some snacks.

I was visiting family in Conifer and the antifreeze reservoir to my Volvo cracked and was leaking. There was no garage in Conifer that would service my C-70. After researching garages I came across Anderson's web page and saw that they service Volvo. When I called them they indicated to me that the first available appointment was over a week out. I initially spoke with Ryan and explained that I was visiting family and was to drive back to Chicago in a few days. He said he would talk to a manager and get back with me. When he called back he said that they would work on my car but it may take a couple of days. I said that would be fine as I just needed the car by Friday. I was impressed by the service because the car was done one day after it was towed to the shop. When I came in I talked to Kurt, like everything else this was also a pleasant experience. He said they they looked over the car and other then the repair everything else was fine. They also replaced the battery in the key fob which was also low. I want to say thank you to everyone at the shop. It’s a stressful experience then your car needs a repair after driving and you are a 1000 miles from home. I will definitely use them again if needed when in the Denver area. This is a shop I would recommend to anyone for their foreign car service. They were professional, courteous, skilled and trustworthy. I wish them continues success because they deserve it!
