2007 Chevrolet Silverado 1500: excessive oil consumption

Filed Feb 18, 2022 · Engine, Transmission · PA

This 2007 Chevrolet Silverado has only 73,730 miles . The vehicle in question has an oil consumption issue and is available for inspection upon request. An oil consumption issue will lead to low oil and low oil pressure which can lead to a fire. Problem has been confirmed by an independent service center. Vehicle has been inspected by a certified automotive technician. Vehicle loses oil close to 100 miles and the add engine oil display on the Driver Information Center. Every trip that is close to 100 miles will cause oil consumption and the Add Engine Oil Will display. Vehicle was taken to a repair shop and i was informed that some Chevrolet Silverado Trucks engines will consume oil due to excessive amount of oil going to the pistons. The pistons result with damage to the piston rings and will need to be replaced. In the long run the engine will lose power start to smoke lose oil pressure and low compression which could lead to a fire .No recall was ever posted concerning this issue. I thought the consumption was due to viscosity breakdown until i noticed it got worse. I did some research and asked several silverado owners and they all had the same issue. I confirmed the issue when i took the vehicle to the technician.This vehicle only has 73,730 miles and i am the first owner.

Motor and excessive oil consumption

Filed Oct 16, 2014 · Engine · 71,000 miles · VA

Bought this truck used had 54000 miles on it. Still had warranty left on it. At 71000 miles started using 1 to 2 qts of oil between changes. The dealer has done all changes on this truck every 3000 to 4000 miles. Asked them why it started using oil and they said they checked and could not find any leaks and didn't know why it was using oil. Have had to add 1 or 2 qts between changes every since the truck now has 107000 miles on it. Their are hundreds of reports of this problem on the internet. Need help in getting this repaired.

Every 2500 mile after a oil change I get a low oil engine light and have to add a quart in a half of oil to top it off again. After doing gm's oil consumption test three times gm tells me that the dealer that I was bring my truck to for the oil consumption test stated that I was drive my truck to hard are I was pulling something.

Around the time my truck hit the 42000 mile mark the oil low indicator warning illuminated on my instrument panel. I took it in to the dealer since it was well under warranty. The dealer began an oil consumption test and the truck continued to go through oil regularly. Sometimes just half a quart but sometimes as much as 1 1/2 quarts. The dealership did work on the engine 6 months into this issue but that did not stop the oil consumption. After dealing with them for over 12 months, and the low oil light coming on 2 more times, I was told there was nothing wrong with the truck and according to gm specs, consuming 1 quart of engine oil every 2000 miles, was acceptable. I called and complained to the gm corporate offices but was told that they could not contradict the dealership since they were the ones monitoring the oil consumption issue. I told them that by their "specs" if I took my family on a road trip from ca to ny and back, I would have to replace at least 3 quarts, or half the total in the crank case, during the trip. I know of no other automobile manufacturer that would find this acceptable. Gm says it is. In my opinion, this is a safety issue that gm is well aware of and failing to address, even when an owner has followed the recommended maintenance schedule and reported the issue in a timely fashion. I will not own another gm product. Their customer-no-service is terrible and contrary to the television ads, they do not stand behind their products.
