Super Slick at John's Automotive Care in San Diego: Synthetic Oil

When you get an oil change, it's always a safe bet to just use the type of oil the manufacturer recommends. But sometimes we're asked if we'd like conventional or synthetic motor oil. We glance at the price tags on the two options and choose the cheaper one. But in this case, the more expensive oil might be the better bargain for San Diego drivers. Conventional oil is made from petroleum. Its molecules form long hydrocarbon chains. Synthetic motor oil is either more highly refined petroleum or completely man-made. Its molecules are more uniform. This provides advantages over conventional motor oil. First of all, the molecular structure of synthetic motor oil makes it more slippery than conventional oil so it lubricates better. This translates to better wear protection for San Diego drivers, cooler operating temperatures and more engine power. Further, synthetic oil is more heat-resistant than conventional oil, and it doesn't vaporize ... read more

Why a Trip Inspection Is a Good Idea

At John's Automotive Care we get a lot of San Diego drivers asking about vehicle trip preparation. That's a big deal. You could be driving through mountains and deserts in some pretty lonely areas around CA, so it's important to know that the vehicle is up to the task and won't leave you stranded.Smart San Diego drivers plan ahead for a major road trip – and there are a lot of things to get ready. Where should you start? You could start with the tires. Look them over for tread wear and check to see that they are properly inflated. Take a quick test drive around San Diego to see if you can feel any vibrations: Are the wheels in balance? Is the car tracking straight? Is the alignment ok? Come to John's Automotive Care for a peace-of-mind trip inspection.6267 Riverdale St San Diego, CA 92120 619-280-9315http://www.johnsautomo ... read more

Relax When the Wind Blows in CA: Winter Car Prep for San Diego Drivers

When autumn comes around in San Diego, leaves fall, nights get longer and there's a definite nip in the air. Time to unpack the boots and gloves and fold some extra blankets onto the beds. It's also time for San Diego drivers to winterize their vehicles.Here is some expert auto advice for San Diego drivers on what vehicles need to keep everyone safe and rolling throughout the CA winter months.1. Check your antifreeze. Top it off or change it if necessary. You don't want your radiator, engine or hoses freezing up. If your vehicle isn't generating enough heat to keep you warm, your antifreeze might be low, or you might have a thermostat problem. Either way, you should get it checked out before the full force of CA winter sets in. If you are due for a cooling system service at John's Automotive Care in San Diego, get that done as well.2. Check your brakes. The slushy wet conditions of winter increase stopping distances. Ice exacerbates the problem. Your f ... read more

When Do My Shocks Need to Be Replaced?

A good suspension system gives a vehicle a smooth, even ride while providing San Diego drivers with good handling and control. But like any system on your vehicle, parts of the suspension system can wear out, leading to a lower ride quality and safety concerns. So it's a good idea for drivers in San Diego to remember their suspension system in their schedule of preventive maintenance. Springs do most of the work of the suspension system. The most common types of springs are coil and leaf, but air springs and torsion bars are becoming more common. The body of the vehicle is “suspended” by the springs.If springs were the only working component in your suspension system, however, you'd spend your travel time bouncing up and down like a bobblehead. That's where your shocks come in. They keep the rebound, or bounciness, of the springs under control. Shocks also keep your tires on the road, which keeps the driver in control of the vehicle. Some vehicles have struts in their susp ... read more

Automotive Tips from John's Automotive Care: Signs of an Alignment Problem

When properly aligned, all of your wheels are pointed in the same direction. Your vehicle will track true and handle the way it is designed. San Diego drivers often associate our wheels being “knocked” out of alignment with an event like an accident, hitting a pothole, curb or some other object. While these can certainly take your wheels out of alignment, the bumps and bounces of everyday San Diego driving take their toll on wheel alignment as well. In addition, your vehicle can lose alignment over time with just normal driving. When your wheels are out of alignment, John's Automotive Care in San Diego can return your wheels to the vehicle manufacturer’s factory settings. Most owner's manuals suggest an alignment check every year or two.  Give us a call.John's Automotive Care6267 Riverdale StSan Diego, CA 92120619-280-9315http://www.johnsautomotivecare.com ... read more

When Are Your Tires Worn Out?

  Hey San Diego area drivers, are your tires worn out? What is the standard for our CA streets? How can you tell on your vehicle?While there may be legal requirements for the San Diego 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 ... read more

Gear Up: Transmission Service at John's Automotive Care in San Diego

The transmission system in your vehicle allows you to change gears. Lower gears are power gears. They get your vehicle moving and get it up hills. Higher gears get the vehicle up to speed and get it rolling faster. If you have a standard transmission, then you have to do the work of shifting gears yourself. But with an automatic transmission, the vehicle shifts gears on its own. It automatically starts out in low gear and automatically shifts to high gears as it gets rolling. Again, it will automatically shift to a lower gear to climb hills or when you need a burst of speed.How does it know when to change gears? Today's automatic transmissions are computer-controlled. The computer gathers information about what the vehicle is doing and changes the gears as needed.Automatic transmissions are becoming more sophisticated all the time. More gears, or “speeds,” are being added. Almost all vehicles have at least four speeds. Five or six is common. Some are even increasing to sev ... read more

John's Automotive Care Maintenance Tips: The Belt Goes On

John's Automotive Care Maintenance Tips: The Belt Goes On

All San Diego service advisors know that without the alternator, the battery will go dead in a few miles. The serpentine belt may also run the pumps for both the power steering and power brakes. And on many vehicles, the serpentine belt powers the water pump. The water pump circulates coolant through the engine to keep it within normal operating temperatures. (On some vehicles, the water pump is powered by the timing belt instead of the serpentine belt.) So you can see the serpentine belt does a lot of work. And it if breaks, it affects a lot of systems. That's why your vehicle manufacturer and your service advisor at John's Automotive Care have recommended that it be changed every so often so that it doesn't fail.Your friendly and knowledgeable John's Automotive Care service advisor can perform a visual inspection of the belt to see if it has any cracks that signal the belt could fail soon and will m ... read more

Automotive Tips from John's Automotive Care: A Broken or Damaged Timing Belt

The timing belt rotates the cam shafts which open and close the valves that allow air, fuel, and exhaust to flow through the engine as it powers your car when you drive around San Diego.An old timing belt can lose a “tooth” in the belt allowing it to slip. The engine could stop or misfire. Timing belt slips – or a broken timing belt – can be disastrous on some engines. In “interference” engines, open valves can get in the way of the piston when the timing belt breaks or slips. When that happens one or more valves can be bent requiring expensive engine repairs.It is important for San Diego drivers to replace their timing belts as recommended in their owner’s manual to avoid unnecessary breakdowns. Ask the team of professionals at John's Automotive Care in San Diego if it’s time for your timing belt to be replaced. John's Automotive Care6267 Riverdale StSan Diego, CA 9212061 ... read more

John's Automotive Care Service for Your Exhaust System

John's Automotive Care Service for Your Exhaust System

Your vehicle's exhaust system is more than just a tailpipe and a muffler. In fact, it is one of the most complex systems on your vehicle. The manifold is attached to the vehicle engine. It collects exhaust from the cylinders and directs it into the exhaust pipe. Gaskets seal the connection of the manifold to the engine and to other joints. A cracked or loose manifold or a leaking or damaged gasket can allow dangerous gases to enter the passenger compartment of a vehicle. One of these gases is carbon monoxide, which is colorless, odorless and deadly. For this reason, it is important San Diego residents keep their exhaust system in good repair. The pipes that connect the various parts of the exhaust system can rust or be damaged by rocks or other road debris. Such damage can cause dangerous gases to leak into the air.The catalytic converter is the next component of your vehicle exhaust system. It sort of looks like a ... read more
