Is Silverado 6.2 Reliable?
There are five types of engines in the new pickup. It’s worth your attention to each of them.
One of the most popular choices is the 6.2-liter V8 engine which is not new in terms of technology.
We know a lot about this engine, but we have to admit that it has been altered to fit modern requirements.
Problems, longevity, construction, gas mileage, etc. are some of the issues with the 6.2L V8 gasoline unit in the 2021 Silverado 1500 engines.
We want to know if it’s the best engine for a new truck, or not. We want to make sure the Chevy trucks are good competitors for other trucks.
Let’s get started!
What Do We Know About the Silverado 6.2l Engine?
This is one of the engines available.
There is a 4.3L V6 that is a base engine, a 5.3-liter V8 that is a top engine, and a 6.2-liter V8 for top trims. The last gasoline option is the turbocharged 2.7-liter L4.
You can choose a diesel engine that has a 3-liter capacity. The choice is wonderful, but what should you do with it?
The 6.2 V8 is one of the best engines in Chevy’s lineup and we would go with it. This engine was manufactured by the company for a long time.
The technologies that are used in this series have been around a long time. There are some weak and strong points in the engine.
- The engine is a 6.2L V8 EcoTec3 and it is important.
- This engine is in the Chevy lineup and is called the LS-series or small-black.
- There is a wonderful 10-speed automatic transmission that comes with the engine.
- The engine has 8 cylinders and has a Torque of over 450 lbs.
- Light-duty and heavy-duty trucks have the 6.2-liter V8 engine modified for use.
- The engine is used in Silverado, Tahoe, Escalade, Suburban, and also in GMC Sierra, and Yukon.
This is a high-quality engine that has been around for a long time. There are still some problems that it has.
We know a lot about its good and bad sides because of its popularity. In this article, we will try to reveal both of them.
The engine from this company is even better than many similar engines from other companies.
The engine under the hood of the Silverado 1500 would be perfect for us. It’s easy to repair and it’s relatively inexpensive to maintain.
Gas Mileage of a 6.2 Silverado
According to our investigation, the Chevy Silverado 1500 with the 6.2 EcoTec3 engine offers 20 miles per gallon on the highway and about 16 miles per gallon in the city.
The engine is a V8 and it has more than 6 liters of displacement. It’s powerful and so you can’t expect a lot of miles per gallon of gasoline.
If you compare this with a 5-liter Ford F-150 that has less power and Torque, you will see that the F-150 offers more mileage on the highway.
The fuel consumption of the Silverado with the 6.2 is not that bad. It will prompt you to go to the pump more often.
We don’t know if a powerful gasoline truck would be able to do that. If you don’t want to spend a lot of money, the 2.7 turbo is the better option.
On the highway, it will offer 23 miles per gallon and 20 miles per gallon in the city.
The Longevity Silverado 6.2
These engines are very reliable. The manufacturer knew that not all drivers would service the engines as they should, so they made the engines for light-duty trucks.
The engines have no major problems up until the 250,000-mile mark, and that’s because of that. They can show some trouble after that, but they are still economically acceptable.
We’ve seen a vehicle with over 400,000 miles on its odometer. The average lifespan of the 6.2 Silverado V8 engine is 300,000 miles.
The engine starts dying after that and you have to be careful.
It depends on many things:
- Conditions of Use.
- Yearly Mileage.
- Driving in Dusty Areas.
- The Quality of Fuel.
- Understanding Minor Problems.
- On-time Repairs.
If you know that there is a problem with the 6.2 V8 engine, you shouldn’t drive the truck. You should not buy fuel and oil that is bad.
You can use the truck for a long time without having any problems and it will be more economical than buying an air filter or something like that.
There aren’t many serious issues happening with these engines. Some people still write in their reviews that they don’t like injectors.
We believe that it’s not about the manufacturer’s mistakes. The bad quality of the fuel this person buys is what it’s about.
Big-displacement engines aren’t the engines that can burn fuel right now. Good premium fuel is the only thing that can make them work well.
Here are some issues:
- There are Engine mounts that are malfunctioning. You will probably have to replace at least one or two months after 100,000 miles. Replacement of the mounts will help if the engine vibrates or shakes too much.
- There are problems with the fuel pump. It’s always bad for the fuel pump when the direct injection needs high pressure. If the pump doesn’t work one day, you’ll have to do something quickly. The cost of the fuel pump is related to that.
- The consumption of fuel is excessive. The first thing you should do if you have this problem is to check the spark plugs and coils. Sometimes one of the engine sensors is broken and the standard Chevrolet problem can be solved with the help of engine diagnostics.
- The amount of oil consumption is excessive. After 100,000 miles, this engine will start burning some oil. And it’s all right. If the consumption is excessive, you will most likely need to replace the engine heads or the piston rings. It was expensive, that’s what we should tell you.
- There have been overheating problems. The engines aren’t made to do much to rev them up a lot. They are big-displacement engines that give good power at low revolutions per minute and they don’t like rotating like crazy. It will be necessary to repair your engine if it is overheated.
- There is a problem with overloading. You can use your truck to tow a trailer if you own one. You should always remember the restrictions that the manufacturer gives in their instructions. Get to know the max amount of cargo your vehicle can carry.
When driving a truck with a 6.2-liter V8 engine, there are several issues you can encounter.
We don’t think the issues say anything about the problem with the engine. The problem with driving conditions and servicing is what most of them are talking about.
If you maintain it well and don’t kill it when driving, you will be able to drive your Silverado 1500 6.2 V8 for many years without problems at all.
Catalytic Converter Problem
The biggest engine in the truck has the largest cat converters. At 100,000 miles, they could start malfunctioning. It’s not possible to get a cat conversion for 300K miles.
If you want to pass the fog test sooner or later, you’ll need to replace a cat. There can be a problem with this.
Depending on the year, the system has two or three cats. If you want an aftermarket option, you will have to pay over $1,200 for each cat conversion.
The positive thing is that you can make some money selling your scrap cat converter to a recycling company.
The engine of the car is really good. It’s one of the best V8 engines in the Chevrolet lineup and it’s fun to drive.
If you drive the vehicle carefully, this engine is not very bad for fuel mileage. There are only a few common problems that are easy to deal with.
We have to acknowledge that repairing and maintaining this engine is not cheap.
If you notice that your 6.2 engine is malfunctioning more often, you should consider buying a different vehicle.
