Abstract : A determination by GOST 12275-66 of mechanical impurities in oils containing and lacking additives was accurate according to electron micrographs of the ppts. and evaporated filtrates when the oil and additive were removed from the residue on the No. 4 mitrocellulose membrane filter (pore size 0.9 mu) by washing it 3 times with 30 m liter portions of 'Kalosh' gasoline. Determinations by GOST 6370-59 were inaccurate.
