ALERT ENGINE AIR INTAKE COKING CLEANING AND Gasoline Direct Injection Engine damage

​IMPORTANT NOTICE
      GASOLINE ENGINE PREVENTIVE SERVICE

    ALL GASOLINE ENGINE CARS ARE PRONE TO "COKING" THE INTAKE.
ESPECIALLY
  GASOLINE  DIRECT INJECTED ENGINES ARE AT RISK OF ENGINE DAMAGE.
To see it click on GDI ENGINE DAMAGE  and fast forward to minute 10:00 and watch for 5 minutes.
Post-2006 ALL vehicles: "INTAKE CLEANING SERVICE"  every 24 months

G D I  VEHICLES
AN INCREASING NUMBER OF GASOLINE ENGINED CARS AFTER 2011 ARE GDI. THE FOLLOWING IS RECOMMENDED TO HEAD-OFF MORE EXPENSIVE WORK AND THE DOWN TIME:
IF GDI VEHICLES ARE PAST 40,000 MILES

BACK STORY
Pre-1991 GASOLINE fuels were not completely refined (grossly loaded with non-fuel junk) that loaded up the intake and valves with carbon, enough so that if the engine started it would be unable to be driven until fully warmed up. Premium was the cleanest, Regular was the dirtiest. Routine cleaning became a necessity and was sufficient.  In 1991 the EPA mandated all gasoline to be clean. Problem solved. Then starting in 2014 or so, rapidly worsening from 2020, the problem was (is) back due we think to increased ethanol. And worsening by the year. We have seen an ever increasing occurrence of this coking condition.  The more short local drives the sooner the onset.  The more advanced the condition, the more difficult to remedy. THE ISSUE IS THAT WHEN Gas Direct Injected (GDI) ENGINES ARE EXPERIENCING ENGINE DRIVABILITY AND OIL CONSUMPTION ISSUES, THE DAMAGE LIKELY HAS ALREADY OCCURED..  
The root of it is the degraded motor oil.  Properly timed oil services will dramatically reduce the cause of this coking condition.  The high precision of the engine requires a high standard for the lubricating oils.  There was a time when low compression tractor engines were OK with just about anything like an oil. 
 
BOTTOM LINE: We much prefer to keep your engine healthy with a simple service.  With the limited time we have, it's the maxim "make many people happy doing simple things", instead of "make one person very un-happy doing ONE EXPENSIVE thing" .
