Ultra 5 in 1 Diesel Fuel System Cleaner, STP Concentrated Cleaning Power, Car Accessories, 400 ml

Product Information

A normal car that does not have automatic start-stop can be anticipated to go through around 50,000 start-stop events during the car’s life; however, with the start-stop being activated every time your car comes to a halt, this figure rises significantly.

All of our recommendations above are suitable for both diesel and petrol cars and they simply pour into the fuel tank. However, for the best results, it’s advised that you pour the cleaner into the tank before filling the tank up. Fuel System Issues: If you’re experiencing symptoms like rough idling, poor fuel efficiency, excessive smoke, or reduced power, it may indicate issues with the fuel system, such as clogged injectors or a dirty fuel filter. In such cases, a diesel engine cleaner can help clean the injectors.As the name suggests, a fuel stabilizer must have a strong stability game. Stability is one of the primary reasons to use such a product. I was recently sent a bottle of STP Ultra 5-in-1 Fuel System Cleaner to try out, and it couldn’t have been better timing with a Southern California heat wave hitting; our already pretty crummy 91 octane “summer blend” fuel is working extra hard to help fuel my turbocharged inline 5 cylinder Audi TTRS. STP has developed a 5-in-1 solution designed to deep clean the fuel system; it also contains friction modifiers that lubricate engine parts such as piston rings and cylinder walls, and keep on top of the negative impacts of the ethanol blended into the gas. Based on STP engineering tests, it’s been proven to remove an average of 60% of ethanol deposits from engine parts and restore 95% of original injector performance. While our friends in Canada have ethanol free gasoline, it’s pretty much impossible to find here in the States, so it’s a good idea to use this once every oil change. Biofuel Blends: If you’re using biodiesel or other biofuel blends, a diesel engine cleaner can help mitigate issues related to water and microbial growth in the fuel system. Our company only sells to the garage industry and sell over 100,000 bottles a month to people who know what they are talking about.

To rate the fuel injector cleaners, not only did we test several formulas (as shown in the image above), but we also based our recommendations on the latest research and a number of factors. Some of the factors that we considered included the additive’s cleaning abilities, brand reputability, treatment duration and value for the money. Best Fuel Injector Cleaner Overview

\n\t\t\tSTP Ultra 5-in-1 Petrol System Cleaner 400ml

This STP Diesel Engine Oil Treatment is specially formulated to clean, protect and look after the key parts of your engine that are susceptible to these deposit build-ups created by start-stop engines.

A diesel engine produces more particulate in the system as a result of combustion that can create deposits in the fuel system and can lead to reduced fuel economy and power. Short stop and go trips are more susceptible to this build-up of deposits, typically due to the diesel particulate filter not getting hot enough to regenerate. STP have a rich history of providing excellent car care products at an affordable rate and their Ultra 5 in 1 fuel injector cleaner is no different in this regard, it’s the best fuel injector cleaner. Designed for use in petrol engines, STP Ultra 5 In 1 cleans the fuel system and the fuel injectors too. As well as thoroughly cleaning the fuel injectors, STP ultra 5 in 1 also prevents the buildup of harmful deposits.

When should I use a diesel engine cleaner?

Unfortunately, start-stop engine technology is more susceptible to deposit build-up - once these have built up in the fuel intake system, you’re more likely to experience power loss, driveability issues and exhaust emissions. Redex specialise solely in producing fuel system treatments and have years of experience throughout that process. Their products are extremely affordable and have been proven to have an excellent impact on engine performance and efficiency. As well as this bespoke diesel version, there’s also a specific petrol version available too. This product is specifically designed torestore performance and reduce emissions and Redex claim it’s effective after just one tank treatment. Due to it’s excellent price point, our advice would be to use this on every single tank fill up, particularly if you aren’t buying premium diesel or petrol.
