5 things you didn’t know your iPhone could do!

Most smart phones do a lot already, but sometimes they do more than you think! Read on to find some potential new uses for your iPhone!

1. Use your iPhone as a leveler for hanging frames etc…

2. Take a “burst” of photos! Sometimes one pictures just isn’t enough. All you have to do is hold the camera button and it will take photos very quickly, until you let go.

3. Take a photo with the volume button! It’s nice to be able to operate the iPhone like a good old camera. 

4. If you’re short on time, get a quicker charge by setting your phone on Airplane Mode
 

5. See the time stamps on your text messages!

All-season tires vs. Winter Tires!

The difference in winter tires starts with the rubber compound, which remains flexible during cold weather rather than hard like all-seasons. Deep grooves (1) in the unidirectional tread blocks (2)clear snow and slush efficiently; small cuts, called sipes (3), grip tiny variations in slick surfaces.
 
All-seasons wear longer because of harder rubber compounds. Drainage channels (1) limit hydroplaning; fewer grooves (2) mean better dry-surface grip. Bidirectional tread (3) allows tires to be rotated to both sides of the car.

Braking

"I'll be fine, I have all-wheel drive." It's called all-wheel drive instead of all-wheel stop for a reason. On all-seasons, the AWD car stopped in the longest distance. On snow tires, both cars came to a halt about a car length sooner—often the difference between a close call and a call to your insurance company. So long story short, Winter Tires will drastically improve your braking distance. 

Acceleration
The difference between Winter Tires and All-Season Tires in terms acceleration time is not that great.

Cornering
This is a very important part of the test, this will allow you to go around an obstacle and back on track safely. Luckily, this is the best result for winter tires, make sure you are riding on winter tires if you often drive on curvy roads, or at higher speeds.

Uphill acceleration
Going uphill on snow or ice can be quite difficult. Especially if your car is heavy and if you’re towing a trailer or anything. On this particular test, having All-Wheel-Drive is the best thing you can do for yourself, but it’s hard to ignore the fact that winter/snow tires do help quite a lot.

Feed your car the right fuel!

Different fuels for different outcomes!

 

Do you still buy the cheapest gas you can find? Ever worry it might mess up your engine? Maybe you should, if you drive a newer, direct-injected car, as the hostile environment these high-precision multi-orifice injectors operate under makes them vulnerable to the performance-robbing deposits cheap gas can leave. 

According to consulting engineer Jerry Horn at Chevron, these deposits are formed from a series of compounds, among them olefins and di-olefins with double-bonds that break down, forming gummy deposits that can alter airflow around intake valves or fuel flow out of injectors. Jim Macias, fuels technology manager at Shell, adds that these carbonaceous deposits start out as one of the 300 compounds in gasoline, then polymerize on hot surfaces. There's no single component to target, which complicates preventing or cleaning them. 

Back in the 1990s, as Tier I emissions regs were phased in, the deposits -- created by fuel impurities -- began causing problems for the emissions gear that manufacturers had to guarantee for 100,000 miles. So the EPA established a minimum fuel-additive performance standard in 1995, but the standard was below what some suppliers were then offering, so many reduced their fuel detergency, making matters worse for the subsequent Tier II standards of 2004. After unsuccessfully lobbying for higher standards, a group of automakers (Audi, BMW, GM, Honda, Mercedes, Toyota, and Volkswagen ) consulted with fuel suppliers to establish a higher voluntary standard, marketed as "Top Tier Detergent Gasoline." 

Top Tier is a performance standard, establishing tests and minimum acceptable results for intake-valve and combustion-chamber deposits, fuel-injector fouling, and intake-valve sticking. It also requires that all fuel grades marketed by the brand meet the standard (not just the premium grade, for example). Additive manufacturers pay for the testing, fuel suppliers pay an annual fee to participate, and compliance testing is conducted by third-party labs. Over and above the three basic tests to certify Top Tier fuels, the major fuel suppliers conduct additional testing. Jerry Horn explains that Chevron is "trying to cover more of the on-road vehicle population with additional engine and vehicle dynamometer tests, and then also we do tests with a cab company in SoCal to test fuels under relatively severe service conditions." A revision to the current EPA and CARB test regimens is also expected in the future, perhaps to include testing of direct-injection, but certainly to change the standardized test engines.

So how do Top Tier fuels like Chevron and Texaco with Techron, Shell's Nitrogen-Enriched, and BP's Invigorate work? Each employs top-secret organic chemistry (Chevron admits theirs involves a polyether amine. Others often employ polybutene amines, if that helps), but by and large the molecules include a "hydrocarbon tail" (that keeps the detergent soluble in fuel) attached to a head that includes a functional group containing nitrogen. When enough of these nitrogens attach to a deposit, it comes off. Then the nitrogens can attach to the clean surface and prevent new deposits from forming. The fresh challenge with DI is designing functional heads that don't lose their cool at temperatures of 4000 degrees F or higher. Chevron and Shell both claim that running a few tanks of fuel can remove the deposits left by miles of use of minimum-standard fuels. 

National gas prices are still well below historic highs, but as for fuel-system cleaning products, Macias cautions "the aftermarket treatments tend to be high-concentrations of these additives. Some of that material can get into the crankcase and the effects are not entirely known. It is a big dose of materials, and we are not sure if it could cause damage to the catalytic converter. The only way to ensure that a vehicle maintains peak performance is to use top-quality fuel consistently." Horn states this about these concentrated aftermarket additives "You can wash [deposits] off, but they'll come back, and any deposits can impact air-fuel mixture and combustion, emissions, drivability, fuel economy, etc."  

If you love your car like you love your pet, feed it the good stuff, at least every other tank or so.

Time to adjust your clocks, explained.

 

Well, it’s that time of the year again. We reach for our phones and check what time it is because we never remember if we have to go forward or backward in time or we do not know if we gain or lost an hour of sleep. In this blog post, we have decided to explain Daylight Saving Time aka DST. We agree that it tends to be quite confusing and some of us do not actually know why we observe DST in some states.

What is DST?Daylight Saving Time (DST) is the practice of turning the clock ahead as warmer weather approaches and back as it becomes colder again so that people will have one more hour of daylight in the afternoon and evening during the warmer season of the year.

The U.S. Energy Policy Act of 2005 changed to Daylight Saving Time, extending it three weeks earlier in the spring and one week later in the fall. Starting March 11, 2007 clocks spring ahead an hour on the second Sunday in March and fall back on the first Sunday in November.

Why do we shift our clocks?

The assumption behind the change was that it would decrease the need for artificial light sources and, as a result, save energy. Allowing us to use more of sunlight during the day and less use of the artificial lighting in our homes and workplaces allow us to save energy.

Who doesn’t do DST?

The state of Arizona and Hawaii do not observe the time change due to the fact that the sunlight is enough for them throughout the day that no change is required to really save energy.
