Gentlemen; 
I wish to let you know that the 
oil which befouled ray spark plugs was not 
your oil. I used MOBILOIL going to Phila¬ 
delphia and had no trouble. Owing to mis¬ 
understanding, I was supplied there with 
some other oil, which caused the trouble 
resulting in my descent. Had I used Mo- 
biloil on my return flight, I should, un¬ 
doubtedly, have made the trip home without 
a stop.
