San Diego Drivers: Is Nitrogen Right for Your Tires?

San Diego Drivers: Is Nitrogen Right for Your Tires?

Should San Diego drivers use nitrogen in their tires? Air’s air, right? Well it turns out there is a difference. At the heart of the matter is maintaining proper tire inflation. When your family car tires are properly inflated, they last longer, handle better and more safely and they save money at San Diego gas pumps.

The problem is that tires filled with air can lose a pound and a half of air pressure every month. This just happens as the oxygen in the tire seeps out as you drive around San Diego. So if you don’t check your pressure for a month or two you can be significantly low – low enough to affect handling, shorten tire life and waste money at the fuel pump. Tires filled with nitrogen will take about six months to lose as much pressure as regular air does in a month. So it’s more forgiving of those San Diego drivers who don’t check their pressure every week.

Also, oxygen at higher temperatures – like those inside your tire when you’ve been driving for a while – oxidizes the inside of your tire. Getting the oxygen out of your tire means that it’ll last longer.

So who’s using nitrogen? Let’s start with NASCAR and Indy. These racers like nitrogen’s ability to maintain consistent tire pressure and reduce tire temperatures under very demanding conditions. The U.S. government requires all commercial aircraft to have nitrogen in their tires. NASA and the U.S. Military use nitrogen. The mining industry has been filling those ginormous tires with nitrogen for years. CA Semi-trucks and trailers are starting to use nitrogen extensively. These guys chart everything they do and they invest in the benefits of nitrogen.

The good news is that nitrogen fill doesn’t cost very much or take long at Mission Hills Automotive in San Diego. It doesn’t affect your tire warranty. If you decide that nitrogen is right for your family car tires, remember that it’s still important to check your tire pressure regularly. You might have a leak that needs to be fixed. And you can always top your tire off with regular air if you need to.

Brake Service At Mission Hills Automotive In San Diego

Filed under: Power Brakes — mission394 @ 7:47 pm

Brake Service At Mission Hills Automotive In San Diego

Most San Diego drivers know that braking means slowing or stopping a vehicle. The mechanical aspects of the brakes themselves are just one issue. There’s also the power brake system and brake fluid. And then there are the tires, which are critical to the effectiveness of the brakes.

Let’s step back. A car or truck rolls brand new off the showroom floor at a local San Diego dealer. It has brand new brakes with brand new brake pads. The brake lines and the power assist are filled with fresh fluid and are completely clean inside. And the family car tires are brand new, with full tread. Naturally, braking power is at its peak performance.
 
Now, as your drive from San Diego to Chula Vista and back, the miles start to add up. Most San Diego car owners tend to focus on the brake pads. In the San Diego automotive service community, the pads, and shoes on drum brakes, are called the friction material. That’s because they provide the friction used to stop the family car. The pads are designed to be effective throughout their useful life – it’s not until they are worn so thin as to be out of spec that they lose stopping effectiveness.

The mechanical parts of the brakes have pistons and springs that get quite a workout while stopping the family car. Over many miles, these wear and get gummed up. They start to lose effectiveness gradually and could even fail. That’s why a regular brake inspection is important. At Mission Hills Automotive, we can test the operation of the brakes and see if any parts need cleaning or replacing.

That leads us to brake fluid service at Mission Hills Automotive. Some of the critical additives in the fluid that lubricate and clean the family car fluid system are depleted over time. That and moisture building up in the system deteriorate the performance of the brake fluid. Brake fluid replacement at Mission Hills Automotive includes flushing the brake system to clean out deposits, water and dirt. Then the system is filled up with fresh fluid.

The tires are what connect the family car to the road. The stopping force is ultimately dependent on the traction provided by the tires. The better they grip the road, the quicker you’ll stop as you drive around San Diego.

For questions about brakes, brake pads, battery service, transfer case service, or tires, talk to Mission Hills Automotive  manager Laralynn, George, & Keith Begin.

Air Conditioning Maintenance At Mission Hills Automotive In San Diego

Filed under: Air Conditioning — mission394 @ 4:46 pm

Air Conditioning Maintenance At Mission Hills Automotive In San Diego

Most San Diego area car owners don’t service their air conditioning until after it fails. Maintaining your family car air conditioning system means that you always have enough refrigerant to properly do the job. Small leaks in the air conditioning system allow the refrigerant to escape and the system can’t cool the air as well.

Along with the refrigerant, a special oil circulates in the system. The oil lubricates air conditioning components, and keeps the seals resilient. Low refrigerant and lubricating oil means that the air conditioning parts will wear out prematurely, and we all know that air conditioning repairs can be costly in Chula Vista.

Air conditioning service at Mission Hills Automotive in San Diego starts with a visual inspection of the components for signs of damage or leaks. The compressor is driven by a belt from the engine, most often the serpentine belt, so it’s inspected for cracks or wear.

The air conditioning compressor and other components are checked for proper operation by your Mission Hills Automotive service advisor. Then comes the leak test. If a leak is detected, often in a hose or connection, it’s repaired and the family car system is retested. Your Mission Hills Automotive technician will also perform a temperature drop test.

If needed, the old refrigerant is evacuated and the system is recharged with clean, fresh refrigerant. A final test insures that the air conditioner is working, and you’re on your way.

How often this should be done at Mission Hills Automotive varies from vehicle to vehicle. Your family car owner’s manual will have the manufacturer’s recommendation and, of course, your understanding Mission Hills Automotive service advisor can tell you. It’s typically every two years.

Wheel Alignment Service At Mission Hills Automotive In San Diego

Filed under: Alignment — mission394 @ 6:39 pm

Wheel Alignment Service At Mission Hills Automotive In San Diego

When all of a vehicle’s wheels are lined up exactly with each other, your wheels are in alignment. Hitting a road hazard in San Diego or even just the normal bumps and bounces of everyday CA driving can cause your family car wheels to be out of alignment. This can lead to expensive premature tire and suspension wear.

Here are some alignment basics from Mission Hills Automotive:
The first angle is called toe: do the wheels point in towards each other or away from each other at the front of the tire.
The next angle is called camber: do the wheels tip in or out at the top.
And finally, there is castor. Castor measures the angle where the front axles attach to the vehicle.

The ideal alignment for your family car was designed by its engineers. Mission Hills Automotive alignment service starts with an inspection of the steering and suspension – so see if anything’s bent, broken or worn out. Then the Mission Hills Automotive technician will look at tire condition. From there, the family car is put on an alignment rack and an initial alignment reading is taken. The wheels are then aligned to manufacturer’s specifications.

Your owner’s manual probably has a recommendation for how often your family car alignment should be checked – usually every couple of years. If you suspect an alignment problem with your family car, get it checked at Mission Hills Automotive before you suffer expensive tire or suspension damage.

Viva la Differential At Mission Hills Automotive

Filed under: Differential Service — mission394 @ 9:52 pm

Viva la Differential At Mission Hills Automotive

With front-wheel drive being so common in San Diego these days, the differential is just taken care of during a transmission service, so most San Diego folks don’t even have to think about it. And most rear-wheel drive family car differentials don’t need to be serviced for many miles, so it’s understandable that it’s not something on the top of mind. So it’s not uncommon for CA people to not know they have a differential let alone know that it needs service.

To better understand what a differential does, think about a high school track. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That’s to compensate for the longer length of the outside lanes. Staggering the starting lines means that each runner has the same distance to run.

The differential compensates for the difference in speeds on drive wheels between the inside wheel and the outside wheel in a turn, because they have to travel together through slightly different distances.

Many family car differentials do a lot of work and require very heavy duty parts. And those parts need protection. The differential fluid lubricates the gears in the differential and keeps them cool. The fluid eventually gets dirty and worn down. Some kinds of differentials require special additives that break down over time. So manufacturers and Mission Hills Automotive technicians recommend intervals for replacing your differential fluid.

Your Mission Hills Automotive service technician will drain the used fluid and check it out for metal bits, which could be a sign of excessive wear on the gears. He’ll then replace the fluid and install the additives if necessary.

San Diego four wheel drive family cars need special attention to their differentials because they have a differential on both the front and rear axles that work at different times and sometimes under heavy loads – so they may need to be serviced at Mission Hills Automotive at different intervals.

Your San Diego service advisor can look up the manufacturer’s recommended service interval or you can check your family car owner’s manual.
