How to Know When to Change Your Oil at John's Automotive Care

How to Know When to Change Your Oil at John's Automotive Care

Today in the John's Automotive Care auto care blog, we're going to talk to San Diego drivers about oil change intervals. It seems that as engine technology advances, oil change intervals become longer for John's Automotive Care customers. For example, recently four of the world's largest vehicle manufacturer's shortened the published intervals for several of their engine models. They originally published intervals that extended out to a much as 8,000 miles (13,000 kilometers).In real world San Diego driving, the oil started to sludge up before the recommended change interval. Oil sludge is a thick jelly-like substance: quite literally petroleum jelly – like Vaseline. This goop was clogging vehicle small engine passages so the oil wouldn't flow to some parts of the engine. This resulted in engine damage. We see it too often at John's Automotive Care in San Diego.The vehicle manufacturers began to offer an extended warranty to cover sludge damage. But there was a c ... read more

Battery Basics for San Diego

Battery Basics for San Diego

It's important for San Diego drivers to know battery basics. First, let's talk about which is harder on a battery – hot or cold CA weather. Most San Diego area drivers think it's cold weather because that's when we call on our batteries to have enough power to start a cold vehicle engine. However, heat does more damage to a battery than cold. Truth is, our batteries start to die a little from day one. Keeping a full charge slows the process, which is hard with short San Diego trips because the alternator doesn't have time to fully recharge the battery from starting the engine. San Diego drivers can top off the charge with a computer controlled battery charger – say, once a month in the summer and every three months during the winter.As far as how long a battery will last, statistics show that 70% have given up the ghost within four years. By that time, they aren't capable of taking a full charge like they used to ... read more

Is Your San Diego Driving Severe?

People near San Diego, CA, often ask John's Automotive Care how often they should have a particular service done. It's a great thing to ask. You can look at your owner's manual or have your San Diego, CA, service advisor at John's Automotive Care look up your vehicle in a service database. What you find is often a surprise to people – there are actually two service schedules.One is the regular schedule and the other is the severe service schedule. Service intervals are shorter on the severe service schedule. When asked, most folks in San Diego will say that their driving is normal and that the 'regular' schedule probably applies to them. 'Severe service' sounds pretty extreme – 'I don't drive like that.'Well, here is what the manufacturers say constitutes severe driving conditions; you can draw your own conclusions. Most of your trips are less than four miles (six and a half kilometers). Most of your trips are less than ten miles (16 km) and outside temper ... read more

Breathe Free in San Diego: Cabin Air Filter Replacement at John's Automotive Care

Breathe Free in San Diego: Cabin Air Filter Replacement at John's Automotive Care

There are a lot of new features, both optional and standard, on San Diego drivers' vehicles these days. One you may not have heard of is called a cabin air filter. Simply put, its job is to keep the air in the passenger compartment of your car nice and clean.A cabin air filter is similar to the filter you use on your furnace at home in San Diego. Cabin air filters can catch particles down to three microns. By comparison, a grain of sand is 200 microns. So cabin air filters are effective against dust, dirt, pollen, mold spores and most pollutants in our San Diego area atmosphere. Good news if you suffer from any types of allergies, or if you live in an area in CA prone to air pollution.Cabin air filters are generally located in the engine compartment or under the dashboard. They can be tricky to access and replace, so you'll probably want to go to your friendly and knowledgeable service advisor at John's Automotive C ... read more

Diesel Maintenance for CA

Diesel Maintenance for CA

At John's Automotive Care we hear from a lot of people who are excited about the new diesel engines that will soon be available in passenger cars and SUV's. But our CA friends are often curious about the preventive maintenance requirements. People may not know that diesel engines have long been used extensively in Europe and Asia. In fact, in some markets, there're nearly as many diesel powered passenger cars as there are gasoline.Here's who's announced or is expected to announce new diesels for North America: BMW, Mercedes, Audi, Volkswagen, Nissan, Honda, Toyota, Hyundai and Subaru. Of course, the US auto makers will be expanding their diesel offerings as well. Diesels will become a very big deal here in CA.You may ask, why has it taken so long getting to CA and North America? There are a bunch of reasons like fuel tax policies and such, but the biggest hurtle was that CA diesel fuel had a high sulfur content – too high for the latest generation of highly refined diesel engines ... read more

Automotive Tips from John's Automotive Care: Air Conditioning Inspection

Most auto manufacturers recommend an interval for an air conditioning system inspection. The inspection uncovers leaks, worn hoses and assesses the condition of the other components.Environmental laws in some around San Diego require leaks to be repaired before refrigerant can be added. Also some parts manufacturers require other components to be replaced along with certain failed parts in order to maintain the new part warranty. This is because a given failure may be the result of another worn or damaged part that will, if not replaced, prematurely damage the new component.John's Automotive Care in San Diego is fully equipped to restore your flow of cool air.John's Automotive Care6267 Riverdale StSan Diego, CA 92120619-280-9315http://www.johnsautomotivecare.com

Stay Headed in the Right Direction, San Diego

Stay Headed in the Right Direction, San Diego

Power steering is standard on nearly every vehicle in San Diego, CA, these days. Now there are some exotic, new types of power steering systems, but for the most part, the general setup is a pump that's driven by a belt powered by the engine. Contact the automotive professionals at John's Automotive Care in San Diego for questions about your power steering. The pump generates power that assists drivers as they steer their vehicle around San Diego, CA. Power steering systems use hoses to move pressurized fluid back and forth. These hoses can develop leaks so it's a good idea to have John's Automotive Care inspect them at every oil change. A check of the power steering fluid level is on the list for every full service oil change at John's Automotive Care because low fluid can damage the power steering pump. And the fluid needs to be compatible with the hoses and seals, so it's important to use the correct type – just ask your servic ... read more
