Why do I need Synthetic Engine Oil?
This is a question that the consumer has asked us at the shop or we have even heard from people in the automotive field that they don’t know why…
There are a lot of misconception about synthetic oil. The most common one is “I heard once I use synthetic engine oil I cannot go back to conventional oil” that statement is a complete false statement! As your auto mechanic my answer always is “How do you know what the people used before you bought the car?” As a statement we have also conducted this test on our personal vehicles and have seen no issues.
Pennzoil states on their website: “You can switch back and forth at any time. In fact, synthetic blends are simply a mixture of synthetic and conventional oils.”
Mobil states on their website: ” Synthetic oils typically provide better protection than conventional oils, but switching back and forth between full synthetic and conventional oil will not damage the engine.”
Since we have that myth squared away, you might be asking “Ok awesome but why do I need synthetic oil when my car takes conventional oil?”
Synthetic oil has been proven to provide a lot of benefits:
- Better engine wear & protection
- Better engine performance
- Longer Oil change intervals
- Less fuel consumption
- Higher viscosity index
- Better chemical and shear stability
- Resist oxidation and thermal breakdown
- Resist engine sludge
- Less waste oil created
Most newer cars today come with synthetic oil from the factory and also require synthetic oil for service. This is a critical thing to remember as putting in the wrong oil in your vehicle will not only potentially damage and shorten the life of the engine! When using the wrong oil in your car while at first it seems to create no issues, in the long run it will potentially create sludge, carbon build up which will lead to a poor running engine, engine oil consumption and also potentially damage emissions components like the catalytic converter.
