What year did GM FIX 5.3 oil consumption?
2014
As we pointed out before, GM redesigned its 5.3-liter V8 engine after the 2014 model year, using different piston rings and adding a shield to deflect oil away from the piston skirts. The newer versions of the engine also feature a true oil level sensor and new valve covers.
Why does 5.3 Vortec burn oil?
The Vortec 5300 engine is equipped with low-tension piston rings that do not maintain enough tension to keep oil from leaking out of the crankcase. The leaked oil finds its way into the combustion chamber where it burned off or turned into a carbon deposit.
What is normal oil consumption between oil changes?
As a rule, most engines with fewer than 50,000 miles shouldn’t use much more than a quart of oil between oil changes (unless the manufacturer says differently).
What years did Chevy have oil consumption problems?
The Chevy Silverado 1500 has had its share of complaints from Chevy drivers, but none as bad as the oil consumption problem it experienced for their 2007-2011 model year pickups. For quite a few years, consumers brought their trucks into the dealerships over and over for the same issue.
What oil does a 5.3 LS take?
If your 2020 Silverado is powered by a 5.3-liter V8 engine, it’s important to use SAE 0W-20 viscosity grade motor oil.
Is DOD and AFM the same thing?
Active Fuel management (AFM) and Displacement on Demand (DOD) are the same thing: a system developed by General Motors that deactivates cylinders during periods of low engine load.
Can I use 10w30 instead of 5W30?
According to API motor oil guide [1], If you are using 10W–30, you can safely switch to 5W–30 (in car engines). 5W–30 is thinner than 10W–30 when cold. (you must follow the manufacturer’s recommendations). However, switching from 5W–30 to economical 10W–30 is not always recommended.
What causes excessive oil consumption in a Vortec?
These 5.3 vortec’s are prone to excessive oil consumption, significantly above standard oil consumption levels. Excessive oil consumption is thought to be caused by the “Active Fuel Management” or AFM system. The AFM system is a fuel efficiency system that selectively “turns-off” certain cylinders while driving for optimum fuel efficiency.
Are there any problems with the GM Vortec 5300?
The lawsuit says GM 5.3L oil consumption problems are caused by defective piston rings, PVC systems and “active fuel management” (AFM) systems that cause the spark plugs to wear out prematurely and the engines to experience all kinds of malfunctions GM made changes to their Vortec 5300 engine design in 2007 in an effort to improve performance.
What are some common oil consumption problems with GM engines?
In December 2016, a Minnesota lawsuit accused GM of selling an engine with multiple defects. The lawsuit says GM 5.3L oil consumption problems are caused by defective piston rings, PVC systems and “active fuel management” (AFM) systems that cause the spark plugs to wear out prematurely and the engines to experience all kinds of malfunctions
What’s wrong with the Vortec engine?
The Missouri based class-action is the latest in a series of suits saying the 5.3L Vortec engine churns through oil because of defects in the low-tension piston rings. The problem is compounded by GM’s questionably designed oil life monitoring system which doesn’t warn owners when oil levels get dangerously low.
