Engine Oil Leaking problems of the 2012 Chevrolet Silverado

Efm issue: life-time chevy Silverado owner, currently own 2003 & 2012 1500 Silverado 1/2 tons. Ever since gm started using efm chips, for some unknown reason the engine will lose several quarts of oil for no reason. Without warning the check engine light comes on. Pull-over & check the oil level. On every occasion, (several incidents now), much to my surprise the oil level barely registers on the dip stick. Where did 3-4 quarts of oil go? yesterday the oil level was full, today the oil level is almost non-existent - without a drop of oil leaking anywhere? I now have to carry 3-4 quarts of oil with me everywhere I go just in case the check engine light comes on. Gm should do the right thing and issue a recall. Warning: if you drive a chevy you better keep 4 quarts of oil with you at all times in the event this happens to you. Not immediately pulling-over & filling the oil level back to proper level may destroy your engine. Fix this efm issue > loss of oil, as it has been going on for years and still persists after 2 complete model changeovers. This major malfunction is the result of the efm system dumping the oil into the exhaust & the catalytic converter burning it away. That is the only plausible explanation for losing so much oil without warning and without a drop of oil being found anywhere outside the engine or underneath the engine compartment or chassis.
