A Check Engine Light can be caused by many factors, such as:
Loose gas cap
Emission control device failure
Mechanical problem with the engine
Up to 100 direct or indirect causes
Normal occasional brake squeal
If you’ve had your vehicle repaired for a Check Engine Light and it comes back on soon after the repair, it may or may not be related to the repair. Remember that the Check Engine Light indicates a failure of up to 100 different causes.
Because a Check Engine Light has so many causes, it is extremely important to have it repaired. Only by having your vehicle repaired each time the Check Engine Light comes on, can you safely operate your vehicle and be assured that you are not causing additional damage and expense to your automotive repair budget.
Note: DEQ will not test your vehicle if your Check Engine Light is on.
For the vast majority of drivers, oil should be changed every 3 months or 3,000 miles. So why do many owner’s manuals recommend oil changes every 5,000 to 10,000 miles?
This recommendation is based on what the manufacturer calls normal driving conditions. Unfortunately, the term normal is very misleading. The vehicle manufacturers definition of normal is a vehicle that is driven long distances, and more than 30,000 miles per year (Most of us drive 10,000 to 15,000). Most people drive their vehicle under severe conditions. If you drive in extreme cold, dusty conditions, or stop and go traffic (most of us) then you are driving in severe conditions and should change your oil every 3 months or 3,000 miles.
Our goal is to not only prevent costly breakdowns, but also reduce your overall cost per mile vehicle expenses. Regular oil changes are the cheapest way to protect your automotive investment.
