Direct injection vehicles

There is a new fad on the market.  It is called direct injection.  This means the gasoline is injected directly into the combustion chamber using diesel technology.

True, the fuel burns more efficiently.  It starts better.  And emissions are reduced.  And the engine has better performance.  But there is always a draw back.

If you have one of these vehicles you need to be aware of something.  Carbon build-up in the intake system.

As we "advance", in our technology of burning fuel cleaner, we take some steps backwards.  The old 1976 Lincoln that your grandpa drove used a carburetor and washed lots of the carbon out of the engine.  Next, we started using electronic fuel injection and our cars started better, but carbon build-up in the intake system reduced the performance over time.  Now, we are using direct fuel injection and guess what?  The performance of your direct fuel injection vehicle can be reduced, not in several years, but in months.  Because of carbon build-up on the valves, intake system, and in the combustion chamber. 

I understand that this is just motor head talk to some of you, but take note.  Ask your mechanic how often you should be treating your engine for carbon build-up.  Some direct injection engines should be treated every third oil change.

Something to ponder when you "move up" in automotive technology.
