Posted on May 31st, 2017 by admin0 under News, Tech Tips.


This link has great information and videos discussing  PPIs for 996 & 986 Porsches

We at Marque Motors preform Pre-Purchase Inspections for Porsche, Audi, Volkswagen, BMW & MINI.  Many customers ask why it takes most of a day to perform this Vehicle Inspection. The link above helps explain what we look for on the Porsche inspections and why. Our inspection includes additional items that are covered under our PPI service.

We have a 4 page extensive inspection.

If we find any “red flags” during the inspection, we will contact the inspection purchaser to inform them of any problems that we have found and this gives this them the option to continue or not continue on the inspection.

Once the Pre-Purchase Inspection has started until it is completed, the information gathered is given ONLY  to the person purchasing the inspection service.

Please feel free to contact us if you have any questions.

Winter Storage

Posted on October 13th, 2015 by admin0 under News, Tech Tips.

Planning on storing your car for the winter months?  If so, please take a minute and read these tips.

To prevent fuel deterioration and corrosion, add fuel stabilizer to your fuel then fill your gas tank.   Drive your car for 15 – 20 minutes to make sure the stabilizer has had time to circulate completely through the system.  To minimize condensation in the fuel tank, it is recommended to fill it to maximum.

Changing the engine oil will prevent internal rust and corrosion.  For water cooled cars, test the antifreeze levels and if needed; flush and refill the cooling system with new coolant, typically every two years.  Brake fluid flushes are also on the two year schedule.  So if it has been two years, it is a good idea to flush and refill with new brake fluid.  Keep the differentials and transmission fluid to maximum level during storage to decrease moisture levels.

Today’s cars have many computers and memory systems.  They will drain your battery even when your car is off and not in use for many weeks.  A battery maintainer is highly recommended to maintain the electrical charge on your car’s battery.  When a battery is not in use or is disconnected, the battery’s internal plates become sulfated and cause premature battery failure.  The vehicle should also be locked in order for the computers to “go to sleep.”  With a maintainer, the battery’s life becomes longer and keeps its capacity restored.

Even the softest car covers will scratch your paint job unless your paint is clean.  Have your car washed and waxed just prior to storage.  Never cover your car with plastic tarps, this will not only scratch your paint, but it can also trap moisture in and under your car.  Discourage the rodents from nesting inside your car by getting the interior detailed.  Get rid of all the crumbs and random debris for eating and nesting. We recommend purchasing peppermint oil and putting a few drops onto cotton balls and placing the oiled cotton balls inside a small dish or screen mesh container, then place them around the car’s interior, engine compartment and trunk.

If your car has a convertible top, always store the car with the top up to prevent creases and permanent wrinkles.

Spray a paint safe lubricant to all your car’s hinges, latches and handles. Also, key lock cylinders if applicable.

Over pressurize your tires to maximum pressure listed on the tire to prevent flat spots and compensate for loss of air during storage.  Make sure to recheck your tire pressure when you go to drive your car.

One more note.  Regardless if your car is in your garage or a storage unit, please make sure to keep your comprehensive insurance active in the event of an unforeseen problem.

So when you pull your baby out on those rare beautiful winter days or in the spring, your car will be ready and waiting!

check tire manufacturer dates

Posted on April 22nd, 2015 by admin0 under Tech Tips.

Do you know how to check the manufacturer date on your tires?

It is important to know how old your car tires are.  Rubber ages, becomes brittle and hard which leads to less traction and cracking. Having old tires can cause slippery traction on wet roads.

Check out Tire Rack on our Links page for more info.

Please call for an appointment or have any questions. 503.293.5386

Cold Facts About A/C

Posted on April 7th, 2011 by admin0 under Tech Tips.

How did we ever get along without air conditioning in our cars? It’s a feature we take for granted until, suddenly, it’s blowing hot air.

In the past few years, many owners have discovered that fixing an inoperative air conditioner can cost a few hundred dollars or more, depending upon the make and model of vehicle. The reason is that the old standby R-12 refrigerant, trade named DuPont Freon, has been replaced by R-134a. Touted as being environmentally safer than its predecessor, R-134a has been standard since ’94.

If your older vehicle needs major repairs to the air conditioning system you can expect to replace refrigerant and the oil in the compressor in addition to the old components. You also may need to install a retrofit conversion. Do not allow anyone to mix refrigerants. They’re not inter-changeable. You cannot add R-134a to your older air conditioner without first flushing the system. Further, according to the Car Care Council, some substitutes are volatile mixtures of propane, butane and flammable hydrocarbons. Keep in mind the fact that if your vehicle is leaking refrigerant, you’re damaging the ozone layer.

An annual inspection of the vehicle, including the air conditioning system, may help forestall costly repairs. So, ask your service center to evaluate your system before those hot and humid days of summer.

Connecting Jumper Cables

Posted on May 21st, 2010 by admin0 under Tech Tips.


In the world of automotive emergencies, motorists need to learn certain procedures for “safety’s sake.”  Two of the most valuable lessons, changing a tire and hooking up jumper cables are best learned before an emergency arises, according to the Car Care Council.

The process of boosting a battery is especially important in cold weather.  Jumper cables or cables on a portable battery maintainer/charger should be connected properly to avoid sparks, which can cause an explosion of the hydrogen gas emitting from the battery.  Beyond this, an incorrect hookup can damage critical, and expensive, electronic components.

The procedure is simple:

Connect the positive (+, red) clamp to the positive terminal of the healthy battery and the other positive clamp to the corresponding terminal of the dead battery.

Next, connect the negative (-, black) or ground clamp to the terminal on the good battery and finally, the negative clamp to the negative terminal on the dead battery, engine block, frame or the other grounded metal. 

When using a portable battery maintainer/charger, the process is much the same.

Connect the positive clamp of the battery maintainer/charger cable clamp to the positive terminal of the dead battery.  Then connect the negative cable clamp to the negative battery terminal, engine block or other grounded metal.

The Council offers an additional suggestion: if you are buying jumper cables or a maintainer/charger, buy the best quality you can afford.  Look for well-insulated clamps and 8-gauge wire.  (Note the lower the wire gauge number, the heavier the gauge).  Under the heavy electrical load of good starting, lightweight cables may not be able to deliver enough current to start some engines.  In fact, they have been known to melt in the user’s hand.

If your battery is three-years old or older and you haven’t had it checked, it’s a good preventive measure to do so, suggests the Council.  A battery’s power is reduced as the temperature drops and that’s when the engine’s starting demands are greatest.

You can always contact Marque Motors and one of our technicians can talk you through the hook-up process or please stop by the shop and we can demonstrate proper battery safety on your specific vehicle.

What you need to know about your car’s oil

Posted on March 12th, 2009 by admin0 under Tech Tips.

What You Need To Know About Your Car’s Oil

By Anthony Gelinas


Is there a difference between “approved” and “meets or exceeds” on that bottle of oil you are about to purchase for your late model European car? The answer is yes!

When you buy “approved” oil, the manufacturer of the oil has taken the time to develop a product that has been formulated to a precise set of standards. Take the clean diesel engine on the new ’09 Jetta TDI, for example. Volkswagen spent years developing a clean diesel engine that could be sold in all 50 states. Three things makes clean diesel possible: a new low sulfur fuel, urea injection systems, and a particulate filter to remove the soot from the exhaust so you don’t see massive black clouds bellowing from the rear. In order for that very expensive part to last, one of Volkswagen’s requirements is that the lubricant has low sulfur, low phosphorus, and low sulfated ash rates. The reason is if the sulfated ashes are too high, it will clog the diesel particulate filter (DPF) causing an expensive repair and the car to fail emissions testing.

This is why it is extremely important to check the owner’s manual of your vehicle to see what the manufacturer approvals are. They come in an alphanumeric code, for example: BMW (LL-04), Mercedes-Benz (MB229.3), and VW (502.00). It is important to make sure that the bottle of oil you purchase has these OEM approvals because it can save you massive amounts of money on future repairs. Approved oil is the lifeblood of your engine, so to prevent being caught in the middle of BFE and being a half a quart low, keep a quart of approved oil in the car. In an emergency, my Audi manual says it is OK to top off with non-approved oil that meets certain industry standards as long as you don’t use more than half a quart. Before long trips, check oil levels before you leave, which is an especially good idea if you own an Audi.

The phrase “meets or exceeds” can be a misnomer. At first glance the word “exceeds” makes you think that it is better than “approved.” Keep in mind that unlike standard oil industry approvals, where an oil can get a grade by being within a range of criteria, OEM-approved oils use a set of standards that have been tested on your vehicle and been proven to work. I would be surprised if a company that uses the term “exceeds” spent the money to have an OEM test its oil only to receive a letter that says, “We’re sorry but your product is too good, we can’t offer you approval.” The same thing holds true with the use of the term “meets.” Since the other oil companies don’t spend the time and money to have the OEM, how would they know it meets the requirement? Plus, if it did really meet the requirement then it would be an approved oil.

So I’m wondering, if the car manufacturers are the ones doing the testing, which costs money, did they spend the money for the test or is it just an assumption?

Some people like to cry foul and say that they don’t think it’s right for a car manufacturer to dictate what type of oil to use, especially if another oil company says their product exceeds their specifications. The other oil company might throw up some test and show some proof that their oil is superior to an approved oil brand. But there really is only one test for approval and that’s the real-world test, which includes extensive testing of emissions, oxidation, wear-and-tear distribution on moving metal-to-metal parts, fuel economy, and severe wear-and-tear testing (about 600 hours of continued use) on your type of vehicle.

When it comes down to it, it’s your car and you can do whatever you want, just don’t be surprised when something fails and the dealer voids your warranty. These oil approvals are like octane ratings: If your gas door says to use 91-octane or higher, there is a reason why the manufacturer spent the time and money to put that sticker there. It’s against the law for a car manufacturer to mandate that you use only their approved products, charge outrageous prices, and prevent other manufacturers from seeking approvals. All car manufacturers open the approval process up to any oil manufacturer who is willing to submit their product and pay for the test. Approved oils are inexpensive (as cheap as $4.99) and they are available almost everywhere. It is not illegal for them to say the use of non-approved oil can adversely affect your new vehicle warranty. Bottom line: To avoid a headache at the dealership when something fails, always use high-quality oil filters, approved oils, and always keep the receipts to show that you purchased an “approved” product. Keep in mind the dealer can run a simple test to determine if you were using approved oil or not.
