Conventional vs Synthetic Oil

The next time you visit a Phoenix VW dealer to get your oil changed and the service attendant asks you synthetic or regular? You just might have to think twice before you answer. Most drivers wonder what the benefits are of using synthetic vs. conventional oil, and if it’s really worth the money.

The truth is, conventional motor oil is a lubricant that is derived directly from crude oil. It has exceptional properties that allow it to provide lubrication at high temperatures, as well as maintaining its stability over long periods of time.

On the other hand, synthetic oil actually begins its life as conventional oil and is then modified to improve its protective and lubricant properties. Some blends of synthetic oil are designed specifically to increase the performance and life of high-mileage cars. Some are meant specifically for high-performance engines. Others actually have the ability to increase your car’s fuel mileage by using special advanced lubricants. Below are some of the most common advantages that synthetic oils offer over conventional motor oil:

Improved Lubrication – Most synthetic oils have added lubricants that increase the ability of the oil to keep engine parts slick, especially at high temperatures. This decreases wear over the long term, and may make your engine last longer.

Better Stability – Synthetic oils are specially engineered to maintain their viscosity (thickness) at higher temperatures and over longer periods of time. This helps you prevent engine wear in several ways

Reduced Breakdown – Synthetic oils are less apt to break down which means that many synthetic oils don’t need to be changed as often as conventional oils. The more durable properties of synthetic oil also means that your engine is protected better through the whole service interval.

Fewer Deposits – As conventional oils break down, they often leave deposits on engine components. This is especially common in engines that run for long periods of time, are driven hard or driven under tough conditions.

If you want to be on the safe side, you can follow what your manufacturer recommends as far as oil goes. In general more performance oriented vehicles require synthetic because of the high heat that builds in these engines, whereas conventional engines don’t require anything special.

Car manufacturers have long sought to create incredibly efficient cars to save motorists money and help the environment. Engineers at Volkswagen are selling what they claim is the world’s most fuel efficient production car. The Volkswagen XL1 ‘super-efficient vehicle’ features new construction techniques, an innovative futuristic-looking body and hybrid drive-train to dramatically increase fuel economy.

The XL1 looks straight from the future and, in a way, it is. Technologically advanced materials like carbon fiber and magnesium make this car years ahead of anything else on the road. It boasts an impressive 261 mpg and is the most aerodynamic car on the road with a coefficient of drag of just 0.189. Visit Chapman VW in Scottsdale for more information.

The XL1 relies on a combination electric-diesel powertrain to achieve such high milage. A 27-horsepower electric motor can run the car for up to 31 miles before switching to the 48-horsepower two cylinder clean diesel engine. Gear heads might initially find themselves underwhelmed by the low power, but the insane aerodynamics and ultralight 1,753-lb body allows the car to cruise at 62 mph while using only 8.3 horsepower.

On the exterior, the XL1 hasn’t changed much since it was first introduced as the L1 concept in 2009. But inside, the car looks very different. Most notably, the old tandem seats have been moved side by side to mirror regular two-seat cars. Originally weighing in at a svelte 837 pounds, the production car is double the original weight, but is also more efficient by 91 mpg.

The Volkswagen XL1 is not yet available in the U.S. To stay up-to-date, visit Chapman Scottsdale Volkswagen.

Fuel and oil additives—what are they, and should I use them in my vehicle?

We’ve all seen the commercials for fuel and oil additives that are supposedly cheap miracle workers for countless engine problems. Like most things in life, if it sounds like it is to good to be true, it usually is. However, some additives are beneficial. Here, we will dive into what’s fact and what’s fiction when it comes to fuel and oil additives. For more information on additives, contact Chapman Volkswagen.

First, always be wary of any type of additive you add to your car. Additives can damage engine sensors on newer cars, so always read the label.

Most additives that claim to stop leaks are just temporary fixes for larger problems. With these, you will eventually end up having to pay to actually fix the problem. However, if you are on a budget and the additive appears to be working, it could allow you to be in a better financial situation before shelling out the big bucks.

Fuel additives have gained popularity over the last few years as they claim to improve fuel economy, performance, and a litany of other vehicular functions. If you are using the correct octane fuel in you car already, the only thing these additives will do is lighten your wallet.

There is one type of fuel additive that can be beneficial for those who don’t drive their car often. Fuel stabilizers and antioxidants are helpful if you do not use a vehicle very often. These will help the gas from getting old and stale, and subsequently keep the car from performing sluggishly, while fending off any possible damage to the fuel system. This goes for fuel system cleaners as well. They can aid in cleaning up the fuel system and increasing longevity.

The effectiveness of oil additives is even murkier. Most claim to stop some sort of leak, though if the engine is leaking any oil, there is a larger problem at hand. If you change your oil regularly and with quality oil, the additives advertised should already be in your engine. Buying high quality oil designed for your car will save you money in the long run.

In the end, if you maintain your car, use quality fuel and oil, and drive it often, any type of fuel or oil additives are simply unnecessary. For the latest information, stop by your VW dealer in Scottsdale.
