Sorrento Mesa Auto Spa is well known for high quality auto washing and detailing, but they also offer a lube service. But often should you be changing the oil on your car? Well, this depends on a few things of things: whether it is older or newer, takes diesel or regular gas, the type of driving conditions, as well as the way you drive it.
Most auto manuals will tell you that you need to change the oil every 7,500 miles in a car that takes gasoline and every 3,000 in one that takes diesel. Pay attention to the fine print and it will say that these numbers are for optimal driving conditions (slow steady speeds in good weather). Most of us don't drive in such conditions especially if we ever are in stop and go traffic in the city or drive over 60 mpg on the highway.
This is why most oil change establishments will tell you to get an oil change every 3,000 miles no matter what. A new engine with little or no wear might be able to get by on 7,500 mile oil changes. But as an engine gets older, blowby increases. This causes unburned fuel to dump into the crankcase which dilutes the oil. So if the oil isn't changed often enough, you can end up with accelerated wear and all the engine problems that come with it (loss of performance and fuel economy, and increased emissions and oil consumption).
