Recently, I had an engine light come on my vehicle display. Next, I took it to my local auto garage to check the code on the engine light. States, [P2191 is an OBD-II generic code for the engine control module (ECM) detecting that the fuel control has reached its rich limits when the engine is under load on bank 1.] Information from . It was nothing serious and my vehicle was still able drive. I had not noticed anything different about driving my vehicle with the current fuel in the tank.

It is believe it might be a fuel sensor, bad quality of gas, or needed a engine flush. The next process was trying Lucas Upper Cylinder Lubricant and Injector Cleaner into the mix of current gasoline. Even if you don’t have any problems with your vehicle it is recommended to add to your fuel supply after 25 gallons on a full tank.

Next, I visited my local Advance Auto Parts in Central Florida and purchased a 5.25 ounce bottle of Lucas Upper Cylinder Lubricant and Injector Cleaner for $3.99 plus tax. The product UPC code is 0-49807-10020-9. This product can be used for gasoline or diesel fuel as stated on the product label.

On the product front label is says it is a “Tune-Up in a bottle, the complete fuel treatment.” Plus, use every fill up for “Maximum” power & fuel economy, eliminates need for higher-octane fuel, safe for any engine. Plus, product claims to counteracts negative effects of reformulated gasoline.

Then on the back of the label it says, [Before-After fouled injectors can cause: 1. Loss of fuel economy, 2. Loss of power, 3. Burned pistons, and 4. Premature overhauls. Cleans and lubricates carburetors, injectors and valve seats.]

I poured the entire bottle Lucas Upper Cylinder Lubricant and Injector Cleaner into my gas tank. My tank was three-quarters full. I had notice any changes yet on the first day. The engine light is still on.

Because the engine light never went off, I decided to take it to my auto repair shop. There they conducted a diagnostic on my vehicle and found it needed an engine flush. It was due for it for a while. This task should be done around 50,000 miles.

It was the right choice and now the vehicle engine light is off and my vehicle is running even better now.

Finally, I highly recommend this product to all vehicle owners and operators. I will continue to buy Lucas Upper Cylinder Lubricant and Injector Cleaner to keep my vehicle at top performance. You should too. For more information on this product please visit .
