Just before the warranty ran out, I
noticed the car "using" oil. I was
told that it was normal for a Northstar
engine with over 50,000 miles on it
to "use" oil at a rate of 1qt. per
1,000 miles. When I asked them to
define "using", they of course could
not. I understand that the car may
actually be burning that oil and that
it is not immediately noticable because
the tell-tale blue smoke that is
usually associated with burning oil is
captured in the catalytic converter.
For those of you who are being sold a
decarbonization process for $500, don't
agree to it unless GM is paying for
it. The process does not do a thing
for the oil "usage"!!
Heated seats & 8-cylinder engine (when
it is not "using" oil)
Design a new Northstar engine, call it
The Northstar II, and do away with
the "using oil" option.
