The easiest way to tell if your 5.3 is flex fuel, is to look at the engine itself. If there is a yellow sticker that says “FFV” on it then your engine is indeed flex fuel. Other ways to tell include looking in your vehicle’s owner’s manual or contacting your local dealership where you purchased the car.
They will be able to tell you for certain whether or not your car has a flex fuel option.
If your Chevrolet Silverado 1500 has a 5.3L engine, then it is flex fuel capable. This means that the engine can run on either gasoline or E85 ethanol. However, you will need to have a few things in place before you can start using E85.
First, you will need to have an E85 compatible fuel system installed. This includes the tank, pump, and injectors. Second, you’ll need to tune the engine computer to accommodate the different fuel mixture.
Third, you may want to install larger injectors to account for the higher volume of ethanol in E85.
Once everything is installed and tuned properly, you’ll be able to fill up with either gasoline or E85 without any issues. Just remember that E85 has less energy than gasoline, so your mileage will suffer somewhat when running on this fuel.
Flex Fuel Vin Table
Flex Fuel vehicles have become increasingly popular in recent years as a way to save money on fuel costs. However, there is still some confusion about what exactly a flex fuel vehicle is and how it works. In this blog post, we’ll clear up some of that confusion and provide detailed information about flex fuel vin tables.
A flex fuel vehicle is one that can run on either gasoline or ethanol (a type of alcohol). The percentage of each that the vehicle can use depends on the specific model; most can run on up to 85% ethanol (E85).
To find out if your vehicle is flex fuel compatible, you’ll need to check the Vehicle Identification Number (VIN).
This can usually be found on the driver’s side door pillar or inside the glove box. Once you have the VIN, you’ll need to consult a flex fuel vin table.
These tables are available from a variety of sources, but we’ve provided one below for reference.
It lists commonflex fuel vehicles by make and model year. If your vehicle isn’t listed, that doesn’t necessarily mean it isn’t flex fuel compatible – it could just mean that it wasn’t manufactured as a flex fuel model originally. However, you should still double-check with your dealership or car manufacturer to be sure.
Make Model Year Percentage of Ethanol Compatible
Chevrolet 2010 85%
Ford 2006-2010 85%
GMC 2007-2010 85%
Nissan 2011+ 100%
What Vin Number Indicates Flex-Fuel?
What is a VIN?
The Vehicle Identification Number, or VIN, is a 17-digit code that uniquely identifies your vehicle. It’s usually located on the dashboard on the driver’s side, and it can also be found on your car’s insurance card or in the owner’s manual.
The VIN can tell you a lot about your car, including its manufacturer, year of production, assembly plant, and more. For example, if you know how to read a VIN number, you can find out if your car has airbags, anti-lock brakes, or other safety features. You can even use it to check for recalls.
One thing the VIN won’t tell you is what kind of fuel your car uses. However, there are some ways to figure it out. Here’s what you need to know about finding a flex-fuel vehicle by its VIN number.
What is flex-fuel?
Flex-fuel vehicles are designed to run on either gasoline or ethanol (a type of alcohol made from plants). Most flex-fuel cars and trucks sold in the United States can use up to 85% ethanol (E85), while some newer models can handle up to 100% ethanol (E100).
How do I know if my car is flex-fuel?
If you’re not sure whether your car is flex-fuel, there are a few ways to check. First, look for an “FFV” badge on the outside of the vehicle or in the owner’s manual.
You can also check the doorjamb sticker for mention of E85 compatibility, or look up your car’s specifications online using the VIN number.
How do I find my car’s VIN number?
As we mentioned before, the Vehicle Identification Number (VIN) is typically located on the dashboard on the driver’s side — near where the windshield meets the hood — or on your car’s insurance card or in the owner’s manual .
In most cases , it should be easy to spot without having to get down on your hands and knees . Once you’ve found it , take a look at this infographic from HowStuffWorks that explains how to read a VIN :

How Do I Know If My Ls is Flex-Fuel?
If you’re unsure whether your LS is a flex-fuel model, there are a few ways to check. First, check the vehicle identification number (VIN). If the eighth digit of the VIN is a “3” or a “4,” then your LS is a flex-fuel model.
Another way to tell is by looking for the flex-fuel badge on the rear of the car. If it’s present, that’s another indication that your LS is able to run on E85 fuel.
Finally, you can check the owner’s manual.
Flex-fuel models should have mention of the capability in the manual.
If you determine that your LS is indeed a flex-fuel model, congrats! You have a car that can run on either gasoline or E85 ethanol fuel.
Just be aware that if you do choose to use E85, you’ll need to fill up more often since it has lower energy density than gasoline.
How Do I Know If My Engine is Flex-Fuel?
If you’re not sure whether or not your car is flex-fuel, there are a few ways to check. The easiest way is to look for a yellow sticker on the inside of your gas door. If you see one that says “E85/Gas,” your car is flex-fuel.
Another way to tell is by looking up your car’s VIN number. Every car has a unique VIN, and you can usually find it on the dashboard, driver’s side doorjamb, or in your insurance documents. Once you have the number, plug it into an online VIN decoder (like this one: http://www.decodevin.com/).
This will give you a rundown of all the specifications of your car, including what type of fuel it takes.
If neither of these methods works for you, consult your owner’s manual. It should have information about what kind of fuel your car needs.
Generally speaking, if your engine is designed to run on E85 gasoline, it will be able to run on any blend of ethanol and gasoline—from 0% ethanol (regular unleaded gasoline) up to 85% ethanol (E85). That said, it’s always best to check with your manufacturer before using anything other than regular unleaded gasoline in your flex-fuel vehicle.
Is 5.3 Vortec Flex-Fuel?
Yes, the 5.3 Vortec is a flex-fuel engine. This means that it can run on either gasoline or ethanol (or a mixture of the two). The engine has been specifically designed to run on flex-fuel, and as such, it includes certain components (such as an Ethanol Sensor) that are not found on other engines.
The 5.3 Vortec is a powerful and efficient engine, and the fact that it can run on flex-fuel only adds to its appeal. If you’re looking for an engine that can run on both gasoline and ethanol, then the 5.3 Vortec is definitely worth considering.
Conclusion
If you’re driving a GM car or truck from the early 2000s onward, there’s a good chance your vehicle is capable of running on E85 gasoline. But just because your car can use this biofuel doesn’t mean it’s necessarily a flex-fuel vehicle. So, how can you tell if your 5.3 is flex fuel?
The easiest way to tell if your 5.3 is flex fuel is to look for a yellow sticker on the gas cap or door jamb that says “E85/Gas.” If you see this sticker, then congratulations! Your vehicle is indeed flex fuel.
If there’s no such sticker, don’t despair. There are other ways to determine whether or not your 5.3 is flex fuel. One method is to simply check your owner’s manual; if it mentions that your car can run on E85, then it’s definitely a flex-fuel vehicle.
Another way to tell if your 5.3 is flex fuel is by looking at the engine itself. If you see a black hose connected to the intake manifold with a quick-disconnect fitting, that’s an indication that your engine was designed to run on E85.
So, there you have it!
These are just a few of the ways you can determine whether or not your 5 . 3 liter engine is actually flex fuel . Now get out there and start saving money at the pump!
