Oil Thursty Caddy
By Tonyl on
1996 Cadillac Seville STS 4dr Sedan
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"!!
Favorite Features
Heated seats & 8-cylinder engine (when it is not "using" oil)
Suggested Improvements
Design a new Northstar engine, call it The Northstar II, and do away with the "using oil" option.
