I just recently purches a 1997 Es300 With 123,000 miles on her...The car looks Imaculant ..Timming belt was done at 80,000miles. I have been use to the 92 series and I am not to fimilar with this generation. I have searched the forums and seen there is a promblem with engine sludge. Unfortantly I dont have the maintance records for oil changes.I Had my mechanic put oil cleaner through the engine and plan on changing the oil Every 1,500 miles for the next 10 oil changes. My Question is if there is sludge in there , would this process help clean it out??????The Engine purrrs like a kitten , No abvious signs of mechanical failure.
Another Question is, if the backlighting in the cluster unit should fail , is it servicable ? Meaning is there bulbs that can be replaced ?
