Reviews
Here are some reviews from satisfied customers who have experienced the benefits of using this fuel system cleaner:
“I used this in my Camry that had a jumpy idle at stops and start-up. With a couple revs, it was gone and hasn’t come back since. I run a bottle at every 4th tank or so as a maintenance thing. Most Chevron gas stations have this in stock and they sell pretty well. I noticed my average gas mileage increased slightly as well.”
“Last summer, I bought a shiny, brand new $300 lawnmower! I was stoked! Well, this year, it wouldn’t start! After some Googling, I learned that apparently gasoline goes bad! Who knew?! Well, I didn’t (obv) & so this was no doubt the reason why my new lawnmower wouldn’t start. Coincidentally, my car hasn’t been getting the greatest gas mileage, so I had already purchased 2 bottles of this stuff (which is showing substantial improvement in that category, btw). I pumped the old gas out of my mower, put in one tablespoon of this stuff along with half a gallon of gas, said a prayer, pulled the cord & VIOLA! She started right up! I couldn’t believe it! Saved $50+!”
“Great awesome, love it. I use this twice a year in a 2017 Honda Pilot. You can feel the difference after the first tankful. Works well, been using this for years in the past and will continue to.”
“I added a bottle of this when I had the oil changed. It seems to have improved the mileage a little bit. I will continue to do it at every oil change every 5000 miles.”
“I used half a bottle for my wife’s 2016 Honda Accord and the other half for my 2021 Honda CRV. The product itself is great; the cars run smoothly on the road and at idle. The only problem I have is that the bottle is bigger. With the big bottle and small gas tank opening of the CRV, the liquid ended up overflowing into the little hole on the side and ending up on the ground. I regret I didn’t use a funnel.”
With these positive reviews, it’s clear that the Chevron 65740 Techron Concentrate Plus Fuel System Cleaner is a reliable solution for optimizing your vehicle’s performance and fuel efficiency.
Fuel Level Malfunction in Corvettes
Common issue with GM Corvettes
If you are a proud owner of a GM Corvette, you might be familiar with the frustrating fuel level malfunction that plagues these vehicles. It seems that GM has been unable to rectify the problem, despite its prevalence in both the C5 and C6 generations from 1997 to 2013. Corvette enthusiasts have voiced their disappointment over the malfunctioning fuel level senders, particularly on the passenger side fuel tank. Once the gauge reads half a tank, it suddenly drops to empty, triggering a Check Gauges Message and a Low Fuel Warning. This misleading reading poses a significant inconvenience for drivers, as they are left with half a tank of fuel but the gauge fails to reflect it accurately.
Impact of malfunctioning fuel level senders
The malfunctioning fuel level senders in Corvettes not only cause frustration but also result in unnecessary trips to the gas station. The inaccurate gauge reading may lead drivers to refuel sooner than necessary, wasting valuable time and money. Additionally, the faulty readings can be misleading, causing drivers to run out of fuel unexpectedly. Overall, this issue can greatly impair the driving experience and become a constant source of annoyance for Corvette owners.
Use of Chevron Techron as a potential solution
In search of a solution to this persisting problem, some Corvette owners have turned to the Chevron 65740 Techron Concentrate Plus Fuel System Cleaner. This fuel system cleaner boasts a range of benefits, including the ability to reduce rough idle, engine surge, hesitation, and spark plug fouling. Moreover, it claims to improve cold start performance and fuel stability for up to one year. These features make it a promising product to address the malfunctioning fuel level senders in Corvettes.
Corvette owners who have used the product report mixed results, but many have observed positive outcomes. Some have noticed a significant improvement in the accuracy of their fuel gauge readings and have been able to resolve the issue without costly repairs. Although Techron may not fix all of the associated issues, it has proven to be an encouraging solution for many Corvette owners.
If you do decide to use Chevron 65740 Techron Concentrate Plus Fuel System Cleaner, it is important to follow the manufacturer’s instructions and not exceed the recommended usage. Excessive use of Techron can thin the oil, leading to potential complications. However, when used correctly, this product can potentially save Corvette owners from expensive repairs and provide a more accurate fuel level reading. So, if you find yourself grappling with a malfunctioning fuel level sender in your prized Corvette, it might be worth giving Techron a try.

Recommended Usage and Precautions
Proper usage instructions for Chevron Techron
When it comes to using the Chevron 65740 Techron Concentrate Plus Fuel System Cleaner, proper usage is key to ensuring optimal results. To begin, it is recommended to use this fuel system cleaner twice a year in your vehicle. Many users have reported feeling the difference after just one tankful of gas.
To achieve the best results, it is important to follow the correct procedure. First, make sure your fuel tank is low on gas. Then, add the Techron Concentrate Plus directly to your fuel tank. Finally, fill up your tank with gasoline. This will ensure that the cleaner is thoroughly mixed with the fuel and able to effectively clean your fuel system.
Importance of running TOP TIER gasoline
In addition to using the Techron Concentrate Plus, it is highly recommended to use TOP TIER gasoline for your vehicle. TOP TIER gasoline contains a higher level of detergent additives compared to regular gasoline. These additives help prevent carbon buildup in your engine, which can lead to rough idle, engine surge, hesitation, and spark plug fouling.
By consistently using TOP TIER gasoline in conjunction with the Techron Concentrate Plus, you can enhance the overall performance of your vehicle, including improved cold start performance and fuel stability for up to one year.
Preventing oil thinning with smart usage
Using the Chevron Techron Concentrate Plus Fuel System Cleaner can also help prevent oil thinning in your engine. Oil thinning occurs when fuel mixes with the oil and reduces its viscosity, leading to decreased lubrication and increased wear on engine components.
By taking proactive steps to maintain a clean fuel system with the Techron Concentrate Plus, you can minimize the risk of oil thinning and ensure that your engine operates smoothly for years to come. Adding a bottle of the cleaner during each oil change, typically every 5,000 miles, can be an effective way to prevent oil thinning.
With proper usage and the use of TOP TIER gasoline, you can enjoy the benefits of the Chevron 65740 Techron Concentrate Plus Fuel System Cleaner. Improved performance, increased fuel efficiency, and a smoother running engine are just some of the benefits reported by satisfied customers. Give your vehicle the care it deserves and experience the difference for yourself.
