2002 Chevrolet Prizm Q&A
2002 Chevrolet Prizm Question: oil consumption
Are there any cheap/reasonable/simple options to reduce oil consumption such as using a onetime/long-term oil additive or convert to synthetic? I’ve owned the vehicle since it had 108,000 miles on it. Oil consumption then was 1 qt. every 3,000 miles. The engine now has 157,000 miles on it and currently uses 1 qt. around 2300 miles on a fresh oil change. It uses the 2nd qt. by 4000 miles which is when I change the oil & filter. I always use a quality conventional oil that meets API SM, SL Service Classification and manufacturers' U.S. warranty requirements. It also meets or exceeds ILSAC GF-4. I’ve tried several different brands but consumption continues to increase. There are no leaks. I use this vehicle for an 80 mile daily commute with 98% highway speeds. I want to avoid costly (internal engine) repairs. Would using full synthetic help after a few oil changes? If so, what are the precautions I should follow for the conversion to synthetic? - doconn9918

Most car manufacturers will tell you consuming 1 qt per 1000 miles is acceptable for a new car. So technically yours falls well within that limit averaging 1 qt per 2000miles. IMHO even 1 qt per 1000 miles is a bit high for any car. My 1999 Camry also a Toyota like your Prism (Corolla)any uses less than .25 qts. per 3000 miles. Just be glad you use less then these people, high oil consumption is a know problem with your car: http://www.carcomplaints.com/Chevrolet/Prizm/2001/engine/excessive_oil_consumption.shtml - Pvt-Public
