The automotive professionals at Autotronics of St. Peter would like to give St. Peter drivers an update on some of the things happening in automotive fluids. You know, vehicles are becoming more sophisticated every day.  Fluids such as, oil, coolant and transmission fluid are becoming more specialized at about the same pace.

The St. Peter do-it-yourselfer has to be pretty careful so that they do not actually harm their vehicle with the wrong type of fluid. That is why so many MN ] owners rely on the advice of their friendly and knowledgeable Autotronics of St. Peter service advisor to not only get the correct family of fluids, but to suggest the formulation that is best for their vehicle and their driving habits in the St. Peter area.

Let’s start with engine oil. St. Peter drivers who have been paying attention will have noticed a number of new oil weights on the MN scene in the last several years. Modern engines are built to much tighter tolerances and have very complicated valve trains. The oil must be thin enough to lubricate complicated parts when the engine is cold. The weight of an oil is expressed in terms like 20-W-50 or 5-W-30. The vehicle manufacturers recommend the weight of oil for each vehicle they make. The recommendation is based on engine design. Your St. Peter service center will know what weight your vehicle manufacturer recommends – and it’s important to follow those recommendations. Your service advisor at Autotronics of St. Peter can also offer suggestions for special formulations and can tell you all about conventional and synthetic oils.

Antifreeze, or engine coolant, is another area that has become more complicated. For a long time, vehicle manufacturers only recommended a couple of different types of coolant. Now, several different formulations are needed because of the high-tech materials that vehicle manufacturers are using to build the cooling system. Using the wrong type of coolant in your vehicle can actually void your warranty, so it’s important to get that right.

Transmission fluid is becoming specialized for St. Peter vehicles as well. New transmission designs have particular requirements that require specific formulations. Recently, new, somewhat confusing, standards for brake fluid have also been released.

Not too long ago, there was a good chance that all of the vehicles at your house would use many of the same fluids. However, as automotive technology advances, the array of basic automotive fluids MN drivers need will grow. And, some of the formulations will cost a little more for St. Peter drivers. Fortunately, Autotronics of St. Peter will continue to update their training to keep pace with technology so that you’ll get the right fluids your vehicle needs. It’s all part of the commitment we make to your driving peace of mind.

Hey St. Peter area drivers, are your tires worn out? What is the standard for our MN streets? How can you tell on your vehicle?

While there may be legal requirements for the St. Peter area, there are safety concerns that go beyond meeting minimum replacement mandates.

Two-thirty-seconds of an inch is the depth of the tire tread wear indicator bars that US law has required to be molded across all tires since August 1, 1968. When tires are worn so that this bar is visible, there’s just 2/32 of an inch – 1.6 millimeters – of tread left. It’s that level of wear that’s been called into question recently.

We’re referring to the tread depth on a tire, it can’t move surface water out of the way and you start to hydroplane.

In a safety study, a section of a test track was flooded with a thin layer of water. If you laid a dime on the track, the water would be deep enough to surround the coin, but not enough to cover it.

A car and a full-sized pick-up accelerated to 70 miles per hour, or 112 kilometers an hour, and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths:

• New tire tread depth
• 4/32 of an inch, or 3.2 mm
• 2/32 of an inch, or 1.6 mm

So what happened with the 2/32 inch/1.6 mm tires on the car? Get this – when the car had traveled the distance required to stop with new tires, it was still going 55 mph/89 kph. Stopping distance was nearly doubled to 379 feet/116 meters, and it took 5.9 seconds.

Wow! That means if you barely have room to stop with new tires, you would hit the car in front of you at 55 mph/89 kph with the worn tires.

Now, with the partially worn tires – at 4/32 of an inch, or 3.2 mm – the car was still going at 45 mph/72 kph at the point where new tires brought the car to a halt. It took nearly 100 feet, or about 30 meters, more room to stop and 1.2 seconds longer. That’s a big improvement. We can see why Consumer Reports and others are calling for a new standard.

Of course, stopping distances were greater for the heavier pick-up truck.

How do you know when your tires are at 4/32 inch or 3.2 mm? Easy; just insert an American quarter into the tread. Put it in upside down. If the tread doesn’t cover George Washington’s hairline, it’s time to replace your tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

You may remember doing that with pennies. A penny gives you 2/32 inch, or 1.6 mm, to Abraham Lincoln’s head. The quarter is the new recommendation – 4/32 inch, or 3.2 mm.

How do people feel about replacing their tires earlier? Well, tires are a big ticket item and most people want to get the most wear out of them that they can. But do you want that much more risk just to run your tires until they are legally worn out?

For us, and we would guess for many, the answer is “no”.

Here’s a travel tip that’ll I’ll bet you didn’t know, and it might keep you safer…
The average American commuter in MN spends two and a half hours daily in their vehicle.
The government says 100,000 auto accidents yearly are caused by drivers who fall asleep at the wheel. (Aggressive driving is the number one traffic safety concern.)
So what does this have to do with how your vehicle smells while you’re driving around St. Peter?

Well, which scent did you think makes drivers more alert?

Is it:

• A. Strawberry
• B. New Car
• C. Pine
• D. Warm Vanilla Breeze

It’s C. Drivers are more alert and have less fatigue with pine scent in the vehicle, according to AroMetrics.

And, drivers were less angry with overall improved driving performance with strawberry and pine scents.
And you thought they just smelled nice.
