[W126 Coupe] LOW COMPRESSION

[AZTECPILOT at aol.com]

My 1990 SEC (110,000 miles) has been using Mobil Delvac 1300 in 15-40 Wt  
for the past several years. I usually run 6000-7000 miles between oil 
changes.  There is negligible oil consumption in those miles, not enough to notice 
on the  dip stick. Haven't checked the compression, but the engine idles 
extremely  smooth, no vibration what so ever. When the compression begins to be 
a bit  uneven, one can usually feel it at idle RPM, even though the engine 
still makes  good power. About twelve years ago, when I first bought the 
car,  Kendall  brand oil had been used. You may think I am crazy, but when I 
check the oil or  ATF, I always sniff the stick. One can tell quite a bit 
about the condition of  the oil or ATF just by the smell. If the fluid is 
becoming contaminated or  has a burned odor, it's time to get it drained and 
flushed even  though relatively few miles may have accumulated since the last  
change. 
 
Just my two cents worth.
