Getting New Tires in Winnetka?

There are so many tire choices in the Winnetka area that selecting the right one can be a bit overwhelming for drivers. And even though it's kind of fun to have new tires on your vehicle, they're a significant investment for most Winnetka area folks so you want do it right.

Tip: talk with your friendly and knowledgeable A.G. Automotive & Diagnosis tire professional. He'll help you sort through the choices.

Here are some of the issues you'll talk about: One is size – you know, all those numbers on the side of the tire. The right size is . All new vehicles are required to have stability control which, along with other important safety systems, is calibrated to work with specific tire sizes. Your Winnetka tire professional can help stay within manufacturer's specifications or program a different tire size into your vehicle's computer.

And you'll want to discuss how and where you drive to determine the type of tire you need: summer, winter,  all season tires or all-terrain. There are tires for every Winnetka auto owner's needs.

Like we said, tires are a big investment, so you want to get a good value on tires. Now that doesn't always mean the cheapest tire. A top tier tire from A.G. Automotive & Diagnosis will last a long time and give Winnetka drivers good performance throughout its life. Tires sold in Winnetka bargain tire shops may not live up to that promise. Again, your friendly and knowledgeable A.G. Automotive & Diagnosis tire professional can give you options that offer the best long-term value within your immediate budget.

Last, with a 2-wheel drive vehicle, it's to always replace both tires on an axle. Modern sensors and computer safety systems for vehicle brakes, stability and traction control need both tires to have the same amount of wear to work properly. And always put the new tires on the rear so you don't fishtail in a turn. With all-wheel drive you should replace all four tires at the same time.

Schedule a tire inspection at A.G. Automotive & Diagnosis to see how much life is left in your vehicle tires and seek the help of a professional when choosing new shoes for your vehicle.

Severe Service Requirements

A lot of Winnetka drivers have asked whether or not they should use their severe service maintenance schedule, which is listed in their vehicle's  owner's  manual. It can be somewhat confusing, so we decided to consult an expert. Cricket Killingsworth is from QMI/Heartland, a manufacturer of automotive products and fluids. She's been in the automotive business for over 30 years and is a speaker, a trainer and a writer.

Cricket says there's so much confusion on this topic because, "Most owner's manuals actually have two maintenance schedules. Sometimes these are called 'regular service' and 'severe service.' Sometimes they're simply called Schedule 1 and Schedule 2. A severe service schedule recommends that things like an oil change, air filter replacement and transmission service be done more often: either in fewer miles or in less time."

Foreign and domestic vehicle manufacturers create a specific schedule for each vehicle they manufacture. So there isn't one generic schedule that applies to all vehicles. In addition to your owner's manual, Winnetka automotive repair centers (including A.G. Automotive & Diagnosis) subscribe to information services that provide the auto maintenance schedules for every vehicle - so they can help Winnetka drivers know when to take care of needed services. Below is a typical definition for severe service.

• Most trips are less than four miles/six and a half kilometers
• Most trips are less than 10 miles/16 km and outside temperatures are below freezing
• You drive regularly in very hot CA weather
• The engine is at low speed most of the time (not on the freeway)
• Stop and go driving
• You drive in in dusty or muddy conditions
• You routinely tow a trailer, haul heavy loads or carry a car-top carrier around Winnetka

It's common sense for Winnetka drivers: Just a few minutes at higher speeds allows the moisture in the oil to evaporate. Very short trips, or trips of less than 10 miles when it's very cold, don't allow the engine to heat up enough to get rid of the water. And water in the oil leads to damaging sludge. Also, towing and heavy loads raise operating temperatures and cause fluids to break down faster. Dusty and muddy driving around Winnetka means that more dirt will get past the air filter to contaminate the fuel system and engine oil.

The bottom line is that you need to decide for yourself if the regular or severe service schedule is right for you, based on your driving habits. Look at your owner's manual or talk with your A.G. Automotive & Diagnosis service advisor who can help you know which schedule to follow.

Here is what a fleet manager said recently: "Since city miles are generally tougher on vehicles than highway miles, we use the manufacturer's severe service schedule as the basis for our preventative maintenance program. We massage those schedules over time, increasing or decreasing the service intervals so that they make the most sense. There is a little bit of art to go along with the science."

Make an honest evaluation of your driving habits. Unless you do mostly CA highway driving in moderate weather, you'll likely have a fairly good amount of severe service mixed in. Some Winnetka drivers just want to play it safe and follow the severe service recommendations, rather than analyzing how they drive each month.

Ask us for help evaluating your driving and service needs.

Fuel Injection Basics for Winnetka

All modern Winnetka vehicles come with fuel injection systems, so it's a topic Winnetka drivers need to know something about. The mighty fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount at the right time—to be mixed with air and burned in the engine.

So how many fuel injectors does your vehicle have? There's one for each cylinder. So four, six or eight for most folks in Winnetka, CA. Some vehicles have 10 or 12 cylinders. The engine control computer makes adjustments to the fuel injector as it monitors the engine and other sensors. Fuel injectors are a pretty high-tech.

A.G. Automotive & Diagnosis can help Winnetka drivers with a fuel injector cleaning service. What's the benefit? In order to work right, the fuel injectors have to deliver the fuel at a precise pressure at a very precise time. It's important that the fuel is sprayed in a particular pattern as determined by the engine design.

Over time, varnish can start to build up in the fuel injectors, effecting the pressure, pattern and timing of the fuel charge. The result is that the fuel doesn't get burned as efficiently as it could. That robs performance and hurts fuel economy.

What about dirty fuel? How does that affect the fuel injectors? The fuel injectors are the last stop in the fuel system. It starts at the fuel tank. Frankly, the best way to keep your fuel injectors working well is to use high quality fuel. It's tempting to shop for bargains in Winnetka with fuel prices as high as they are, but major brands in the Winnetka, CA, area have better detergents and additives and deliver consistent quality.

What about a good fuel filter? The fuel filter is component of the fuel system. Its job is to filter out the dirt and rust that collect in the fuel tank. If it's clogged up, the dirt will bypass the filter and head upstream to the fuel injectors.

It's important to replace the fuel filter when your manufacturer recommends it. That's part of a comprehensive fuel system cleaning.

There are different kinds of fuel injection systems. Port fuel injection systems, the kind most gasoline engines have, operate at 60 pounds per square inch. The injectors for the new gas direct injection engines Winnetka drivers are starting to see require 10 to 30 times as much pressure. And some diesel engines for passenger vehicles have injectors that operate at 30,000 pounds or more per square inch. There's no room for dirt and gum in a precision part like that.

There are a lot of good products available in Winnetka, CA, that can clean fuel injectors. They're best used to prevent fouling in the fuel injectors. Many can't clean a seriously gummed up injector – that requires a professional deep cleaning, like those we offer at A.G. Automotive & Diagnosis in Winnetka. But putting the cleaner in the fuel tank after you've had A.G. Automotive & Diagnosis take a look at your fuel system will help keep it clean. Be sure to read the label for directions.

Give us a call if you think your vehicle may be ready for a fuel injector cleaning.

Fall and Spring Checkup in Winnetka

When I was a kid, my dad always made sure he took the cars in for Spring and Fall checkups. I was telling a friend that it's about time to get into A.G. Automotive & Diagnosis for a checkup and he said that he read on the internet that modern cars don't need seasonal service.

My friend is (technically) right about some things, but from a practical standpoint, a seasonal check up still makes sense.

Back when my dad was teaching me about how to take care of the family vehicle, most of them used a different weight of oil in the winter and in the summer. But most of today's modern engines run the same oil year round. High-tech engines and high-tech motor oils are better able to handle the seasonal changes.

Your owner's manual or Winnetka service advisor at A.G. Automotive & Diagnosis can tell you the right oil to use.

Of course, you're concerned about the coolant or antifreeze. You don't want to overheat in the CA summer or freeze up in the winter. Your engine cooling system protects against both of these things. And modern coolant — 'antifreeze' as it's sometimes called — is up to doing both very well. It's designed to last for longer distances than most people drive in a year or two.

So how does a Spring and Fall check-up fit in? Let's start with Spring. Summer is coming. That means heat, more driving and road trips. It just makes sense to check your fluid levels and do a visual inspection to see that everything is up to snuff.

You may not be scheduled to drain and replace the coolant for some time, but you need to make sure you have enough coolant and that you don't have any leaks or hoses that are about to fail.

That's pretty practical: a check-up to see if there are any problems or emerging conditions that could later become a problem, like a cracked belt.

And the same principle applies for getting ready for winter. Cold weather means lots of failed batteries. It takes more power to crank up a cold engine, and cold also decreases the available cranking power the battery has available.

So a battery test in the Fall could tell you if you've got a battery that is running on its last legs. And of course, if you live where winter temperatures get below 45 degrees F (7 degrees C) or you have ice and snow, you'll want to consider changing to winter tires.

So Spring and Fall auto checkups at A.G. Automotive & Diagnosis are practical reminders to get ready for the demands of the hot and cold seasons to come.

And odds are that you have one or more routine services that are due anyway. Like a transmission service, brake or power steering fluid, differential service — stuff like that. Are your wiper blades still good? Are your headlamps starting to dim?

So Spring and Fall, change your clocks, replace the batteries in your smoke detectors and get a check-up for your cars.

See, dad was right again.

Come and see us at A.G. Automotive & Diagnosis for your Spring and Fall automotive checkup.
