Use the oil grade and specification in your owner's manual. Synthetic oil resists heat breakdown better than conventional oil, which helps in Bakersfield summers, but the manual decides what your engine requires.
Key takeaways
- The manual sets the grade.
- Synthetic handles heat better.
- Severe service means shorter intervals.
Read the manual first
It lists viscosity, such as 5W-30, and the required specification. Many newer engines require synthetic.
Why synthetic helps in heat
It resists thinning and oxidation at high temperatures, so it protects better during long hot drives and in traffic.
Severe service
Short trips, towing, dust and extreme heat count as severe service in many manuals and call for shorter intervals.
Oil life monitors
Many cars calculate oil life from driving conditions. Trust the monitor, and do not stretch it.
Change and smog
Fresh oil helps a smog test. Ask for both.
What synthetic grades mean
Oil grade numbers such as 5W-30 describe viscosity when cold and hot. The first number is cold flow and the second is hot thickness. Using the grade your manufacturer specifies matters because tight tolerances and variable valve timing depend on it. Using a thicker oil than specified can cut fuel economy and slow lubrication at startup.
Filters and the rest of the service
An oil change is only as good as the filter. A quality filter holds particles through the interval, and a cheap one can bypass dirty oil. During the service we also look at fluid levels, belts, hoses and tire condition. If you only change oil and ignore the rest, you miss most early warnings.
