Everyone in San Diego, CA, knows we are advised to go to our San Diego dentist twice a year.  Oral-conscious San Diego residents have a teeth-cleaning and examination. Once a year, we get x-rays to look for problems that can't be seen with the naked eye. When our dentist is done, he/she tells us what was found – "Everything's fine, see you in six months." Or "You've got a small cavity starting, let's schedule an appointment to take care of it." By the time you leave, you have a plan for addressing any necessary issues.This system works so much better than waiting for a painful problem before going into the dentist. Small problems are fixed before they turn into big problems. And you avoid those huge bills.If San Diego folks understand the wisdom of using this system for handling dental care, why do many resist when facing the same system for our vehicle maintenance? Following the vehicle manufacturer's recommended intervals can be confusing. First ... read more

If you've been paying attention, you've noticed that vehicle engines are getting more and more powerful in San Diego. At the same time, they are getting better and better fuel economy. I've gotta tell 'ya, most of that's because of technological advances in transmissions. To get a better understanding of why that is, let's talk bicycles.You've probably seen plenty of cyclists on San Diego roads. Perhaps you ride yourself. Then you know that a cyclist's cadence is the number of times per minute he or she pedals. The ideal pedal speed is the zone where they can most efficiently generate power over a sustained period of time. The experienced CA cyclist uses her gears to keep her pedal speed in the ideal zone whether she's climbing a hill, cruising on a flat stretch or killing a downhill.Think of it this way: if you have a 1-speed bike, you really have to pump hard to get up to speed. Your top speed is limited by how fast as you can pedal. And if you're climbing a steep C ... read more

Today, we are talking about your PCV valve. Unburnt fuel is forced into the crankcase as your engine runs.  The PCV (positive crankcase ventilation) valve vents this unburnt fuel and oil vapors from the crankcase and sends it back into the air intake system to be burned in the engine.  A clogged PCV will not allow these vapors to escape. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause vehicle engine corrosion, something we see occasionally at John's Automotive Care. At high speeds on CA freeways, the pressure can build up to the point that gaskets and seals start to leak. Back in the old days, vehicles were simply installed with a hose that vented these gases out into the atmosphere. But starting in the 1964 model year, environmental protection laws required that these gases be recycled back into the air intake system to be mixed with fuel and burned in the vehicle's engine.This is much better for air qu ... read more

When asked, most people think they are good at multi-tasking. Scientific studies, however, reveal that only around 2% of the population can truly demonstrate the capacity to effectively multi-task. For the rest of us who are not so biologically wired, no amount of practice can increase our effectiveness at multi-tasking. Turns out, multi-tasking is almost a superpower. Think of fighter pilots: capable of maintaining their orientation in three dimensional space and performing specific and highly complicated functions while accessing life threatening situations and coming up with an appropriate response. Admit it – you can’t do that. Yet when it comes to driving, we seem to think we are very capable of safely operating a motor vehicle with myriad distractions. 77% of young adults feel somewhat confident that they can safely text and drive while 55% claim it’s easy to text and drive. Can they possibly be right? Let’s look at some statistics. Nearly 23% of all accid ... read more
