Results: Does Wynn’s Total Action Diesel Cleaner Really Work? Before & After Results!

[@StephenHunter-r3v]

Hi, thanks for posting 😊. To add some info for your test of this product - I have used this on a very smoky VW T4 (2.5TDI) and it works. The Wynn's cleaner works, some of the others, not so much. For the T4 I ran 3 bottles through over the course of about 6 weeks and it made a big difference. I have also used it on ford turbo diesels, again it seemed to work. It wont fix a knacked engine but if its just getting a bit clogged it helps . Wynn's works best when used regularly, put some in your tank occasionally and it should help keep the gunge clear. Unless you have a DPF then its gonna clog up entirely at some point anyway😜.

Thank you for your comment and watching 👀 I’m putting together another video on the Wynn’s Noise Reducer and measuring the results with a noise level tester. Out soon.

good video for the dummies like me...watched all 3 ..and would say YES to that ..enjoyed your video..and PROOF that its a prventative measure worth doing ...thanx again for taking the time to share this with dummies like me..

😂Well from one fellow Dummy to another thank you 🙏 and thanks for watching 👀

Almost all diesel engines do not have a fuel pump in the tank, they have a low and high pressure fuel pumps directly driven from the timing gears or cam shaft

Over generalisation. Vw for exam have produced a gigantic amount of popular tdis all with a fuel pump in the tank (along with a tandem in the engine bay). These are shared in a vast number of audis and skodas.

Doesn’t matter where the pump is located. You'll typically find the fuel pump located in the fuel tank. If your car has GDI, there will also be a high-pressure fuel pump located near the fuel rail in the engine compartment. My drawing was simply to illustrate that it’s not a good idea to suck up the deposits at the bottom of the tank running it on empty, diesel or petrol they still have filters that can block by dirty fuel, rust and other contaminants. Primary filter between the tank and the fuel supply pump. A finer secondary filter between the fuel supply pump and the cylinder head with unit injectors. The supply pump and the high pressure pump all can be affected. Thanks for watching 👀

It's the exact opposite, almost all diesel engines DO have a fuel pump in the tank. Your information is about 25 years old, might wanna refresh it

[@03056932]

Old myths about low fuel and the pump. The sock filters any debris at the bottom. And then pickup tube is so low you're either going to be pulling fuel through, cooling the motor, or out of fuel.

[@rustyrestos]

Not so sure, maybe with really new modern car designs. But older ones and classics I have had experience of pump failing due to blocked filters. Leading to new pump and tank replacements. Thanks for watching 👀

[@03056932]

@rustyrestos I won't rule it out. I ran a couple of cars on maximum 1/4 tank for a decade and no issues. On One I pulled the pump and the sock was very clean still. Immaculate even. Anecdotal examples but hey. Thanks for the video

@ Thanks for watching and commenting. Lots of viewers don’t leave comments. It all helps the channel grow 👀

[@dan8789]

I don’t believe that low fuel will suck up more debris as pump is always sucking from lowest point of tank

[@rustyrestos]

@dan8789 Dirt, rust, and debris can enter the fuel tank and accumulate in the filter. Bacteria and fungi can grow in fuel, particularly diesel, creating a sludge that clogs the filter. Google it! Also I have had first hand experience of it.

Worst diagram Totally wrong Fuel doesn’t fill the tank via the pump Fills through a large bore filler pipe directly to the tank Fuel pump has a feed pipe to the injection pump via a filter also has a return line for unused fuel

[@rustyrestos]

Thanks for commenting, although that’s not the point to my diagram it was simplistic yes, to show the concept of the filter becoming blocked by debris etc. Not to demonstrate how it’s filled. And Yes and No to your comment: Yes, in certain vehicle systems, fuel can be returned to the fuel tank via the fuel pump. This occurs primarily in vehicles with a return-type fuel system, where excess fuel supplied to the engine is sent back to the tank. Here are the key details: 1. Return-Type Fuel Systems • In these systems, the fuel pump delivers fuel under pressure to the engine, but any fuel not used by the injectors returns to the tank through a return line. • This process prevents fuel overheating and maintains consistent pressure in the fuel rail. 2. Models Using This Setup • Older vehicles with mechanical fuel pumps often utilize return lines. Examples include many carbureted cars and early fuel-injected models, such as: • 1980s Toyota Corolla and Camry models. • Pre-1990s Ford and GM vehicles with throttle-body injection. • Some modern vehicles with high-performance engines may also employ return-style systems to stabilize fuel delivery during extreme conditions. 3. Modern Adjustments • Most modern vehicles have switched to returnless fuel systems, where the fuel pressure is regulated inside the tank or along the delivery line, removing the need to return fuel. However, in specialized cases or modifications, return systems still exist. These systems reflect different design philosophies regarding fuel efficiency, cooling, and emissions control. Let me know if you’d like more specifics about a particular vehicle type!

@JamieMerchant-w8b Thank you for taking the time to share your opinion. My drawing was intentionally simple and focused on capturing the overall idea rather than intricate details. While I can see how it might not meet everyone’s expectations, I appreciate constructive feedback and will use it to improve my future work.
