How Warranties Work for Used Cars, Part 1

For many of the highest-value items we’ll purchase in our lifetimes, warranties are common areas of interest. Vehicles are no exception – both for new and used cars, warranties are commonly parts of the purchase and help protect the buyer in case of damage in the future.

At Auto Showcase of Tulsa, we’re happy to explain the warranty situation for any of our high-end used cars you’re looking into. How do warranties work for used cars compared to new cars, and are there situations where warranties won’t be available? This two-part blog series will go over everything you need to know about vehicle warranty considerations, including a few terms to know and areas to check into as you research this realm.

New Car Warranty

Understanding how warranties work for used cars first requires grasping their basics for new cars, which will play a role here in many cases. All new cars come with a new warranty, known as the manufacturer’s warranty, which guarantees that a car’s components and systems will function properly under normal driving conditions for a certain period of time.

So how long does a new car warranty last? This will vary widely. Some will be full coverage for a specific period of time or number of miles – warranties covering three years or 36,000 miles (whichever comes first), for instance, are very common. In other cases, warranties will describe certain kinds of coverage, such as powertrain or other specific components.

Extended Warranty

In many cases when a somewhat newer car is sold and enters the used car market, especially when this takes place through a used car dealership like ours, the service department will recondition and restore any significant issues with the vehicle, and it will often enter the dealership’s certified pre-owned program. At this point, the car will often be given an extended warranty beyond the initial manufacturer’s warranty.

Naturally, such used cars will cost more than similar vehicles that do not come with such warranties. Some will add more miles or time to the original, while others will add additional areas of coverage.

Service Contracts

In cases where your used car does not come with an extended warranty, or where the original manufacturer’s warranty is not still in place, there is another option available known as the service contract. There are numerous types of service contracts for used cars, each with different costs and payment formats – many which can be added into your finance contract so you have no out of pocket expense. There are even third parties that offer separate service contracts for a fee.

Debunking Used Car Fuel Economy Myths, Part 2

In part one of this two-part blog series, we went over some of the key myths out there regarding fuel economy in a vehicle. Many of these relate to misconceptions regarding fuel or additives, but there are also several that speak to basic vehicle operations and related themes.

At Auto Showcase of Tulsa, we’re happy to over mileage, fuel economy and any related factors for all of our quality used cars. In today’s part two of our series, we’ll go over a few additional areas of misinformation to be aware of when it comes to gas mileage and fuel economy, including several within the realm of basic operations and several misconceptions that have cropped up here.

“Topping Off” the Car

We’ve all had the experience: The automatic nozzle at the gas pump clicks off, but you try to squeeze just a little more gas into your tank before replacing it. Most assume this is the right move and will improve their fuel capacity in a small way.

Simply put, this is not true. This nozzle pump feature is designed to stop when the tank has reached true fullness – pushing more gas into it afterward actually pushes gas into the evaporation system, where both the gas itself and the system can be damage. This is the single top cause of canister failure in the evaporation system, which is often a high-cost repair.

Cruise Control Factors

This is an interesting area, because part of it is not a myth at all: For many longer drives, cruise control is an effective feature for maintaining good gas mileage. It helps stop you from accidentally accelerating too much or too little during flat sections.

However, for hilly areas, cruise control may actually worsen gas mileage. This is because it may accelerate or decelerate the vehicle in rapid ways that are not ideal for fuel economy, especially when trying to get up a steep hill. For this reason, we recommend turning off cruise control in hilly areas.

Size Myths

You might assume that the smaller and lighter a vehicle is, the better its fuel economy will be. But this really isn’t a major factor – there are incredibly efficient vehicles that are quite large, and smaller vehicles that are not efficient at all. What matters is the engine and various fuel economy features within it.

Fuel Efficiency Lifespan

Finally, there’s a common misconception out there that your car’s original gas mileage will maintain throughout its lifespan. But this isn’t the case – due to things like friction, engine wear and basic aging over time, fuel efficiency gets worse with time. Proper tune-ups and upkeep will limit this wear-down, but there will still be a point where gas mileage begins to trend downward.

Debunking Used Car Fuel Economy Myths, Part 1

When it comes to any vehicle you’re thinking of purchasing, whether new or used, fuel economy and gas mileage will be important factors you’re considering. We all want great gas mileage that will save us money and also benefit the environment – a vehicle’s stated gas mileage is the first big factor to consider, yes, but there are also several others that may play a major role.

At Auto Showcase of Tulsa, we’re proud to offer a wide selection of used cars for sale, from sedans to SUVs, vans, trucks or any other vehicle you might be interested in. We’re happy to discuss fuel economy and gas mileage for any of our vehicles with you in detail to help you find the ideal choice if this is important for you. Sadly, many of these conversations include at least some chunk where we have to debunk a few common myths that have arisen over the years regarding fuel economy – there are so many, in fact, that we’ll use this entire two-part blog series to detail all these fuel economy myths and set the record straight on each of them.


Gadgets or Additives to Boost Mileage

Over the years, various companies or manufacturers have attempted to market various devices or gadgets that speak to gas mileage. Some of these are simply ineffective, and while others do work as they’re supposed to, their actual purpose is not to raise gas mileage (which is not possible using this method – rather, it’s to give you better readouts than your dashboard display in terms of ways you can improve your driving habits to increase fuel efficiency. These latter devices are legitimate, though we’d question their true value; any device claiming to actually raise your mileage on its own is false marketing and should be avoided.

Down similar lines, various fuel additives are marketed as ways of increasing fuel economy, reducing emissions or both. The vast majority of these are total myths, with one notable exception: Additive meant to clean your fuel injectors, which will actually clear up this area if your vehicle has experienced a buildup, and will in turn lead to better mileage.

Higher-Octane Gas

We’re all familiar with three octane levels at most gas pumps, which tend to display them in terms like Regular, Plus and Premium or something similar. These refer to octanes of 87, 89 and 93 in the majority of cases.

All that octane rating refers to, however, is a fuel’s ability to resist knocking or pinging during combustion. It plays no role in fuel economy whatsoever. All you’re doing if you use a higher octane than recommended is wasting money.

Manual Over Automatic

This myth is at least somewhat understandable because, in the past, it was actually true – manual transmissions did get better fuel efficiency than automatics. However, modern vehicles over the last few decades have closed this gap, and there now is no difference between these.

Air Filter Factors

Another previously-true fuel economy factor that’s no longer legitimate is the theme of the air filter impacting fuel economy. For newer vehicles with computer systems, fuel-to-air ratio is adjusted manually, and the filter won’t play any role in fuel economy. However, this should still be done regularly, as it improves engine performance and long-term lifespan.
