Oil Change Interval
This question is ask over and over again as it is hard to get folks thing over the 3,000 mile oil change before it was not this low it could be every 6,oo miles, depending on your driving conditions and habits of driving….
Synthetic oils have really change this.
The Los Altos Town Crier says:
New cars don’t need oil changes as frequently as older vehicles

Q: At the last place I had my oil and filter changed, I was told I should come back after driving another 3,000 miles or three months, whichever comes first. Is that really necessary? I have a 2009 Ford Explorer SUV.
A: This recommendation is actually a carryover from years ago, before engines were built to today’s exacting standards.
Today, the fuel and ignition systems and, in some cases, the engine camshafts, are controlled by sophisticated computer controls that contribute to a longer life for engine lubricants. Many of the lubricants are also built to much higher standards.
The three jobs of the engine oil are to lubricate the moving parts, carry heat away from the moving parts and carry any debris away from the moving parts to the engine oil filter.
The higher quality of many of today’s engine oils allows them to lubricate the moving parts for a longer period of time and carry heat away with a slower degradation of the oil. Both the computer controls and the higher mechanical standards of the engine reduce the amount of debris the oil has to contend with. The debris is mainly the product of the combustion process that takes place in the engine and gets past the pistons into the bottom part of the engine where the oil resides.
Why does this make a difference in the oil-change interval? How frequently do today’s engine oils and filters need to be changed?
It differs depending on the type of oil – petroleum- or synthetic-based. Generally, petroleum should be changed every 5,000 miles or every five months. For top-of-the-line synthetic-based oils, change intervals can be as long as 25,000 miles or one year.
