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. 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. One of the unique features of stp ultra 5 in 1 is its versatility. It can work in any modern gasoline engine such as turbo, direct-inject, hybrid vehicles, etc. Yes! If you want to improve the performance of your car or even your lawnmower, this one product is all you need.

Well, stp ultra 5 in 1 has some cleaning and lubricant agents inside of it. Here, the cleaning agents help to clean the deposits of ethanol. And, the lubricant agents end up reducing friction. Compression test after was 100psi, 105psi, 105 psi, 100 psi. And the idle was drastically improved. The treatment and clearly cleaned the valves and the crowns of the piston(s) levelling out the compressions to somewhere more reasonable. The owner of the car returned to the garage the following day commenting how it was like a different car to drive. The other similar products in the market generally need a refill after every 3,000 miles. However, the usage frequency for stp ultra 5 in 1 is 4,000 miles. 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. Now, you may think, if the ingredients are so common why should you buy stp ultra 5 in 1? The reason is quantity. The stp ultra 5 in 1 contains 3X the amount of cleaning agents and that simply makes it a better option. Versatility:Improved Fuel Economy– A good quality fuel injector cleaner will help the ensure to run in an efficient manner and deliver the exact amount fuel needed without over-fuelling. The fuel injection and fuel system will also be cleansed of all carbon buildup and solid deposits which will result in a vast improvement in fuel economy. Cold Weather: In cold climates, diesel fuel can gel and cause problems in the fuel system. Some diesel additives include anti-gel properties to prevent fuel from gelling at low temperatures. Because, unlike PIB, PIBA has the ability to remove existing deposits. However, it does not have the durability to survive in the combustion chamber. No worries cause that’s where PEA comes into action. A. Our best fuel injector cleaner is the STP ultra 5 in 1 fuel injector cleaner. It’s extremely effective and also offers exceptional value for money. The Best Fuel Injector Cleaner 1. STP Ultra 5 in 1 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.

One bottle is good for up to 35 gallons, so I was able to add half the bottle to my car (12 gallon tank) and half to my wife’s (13 gallon tank) and keep us both good. It’s recommended to top off a tank that is at least half full, so I just added the cleaner after filling up the tank. The new bottle is also compatible with cap-less systems, which my wife’s Ford Focus happens to be. But, here’s where the magic happens! The cleaning agents of the product help to keep the fuel system clean by preventing further gum formation. Diesel fuels may form waxes or be contaminated with water that can plug the fuel filter. These conditions may result in poor starting, rough idling, poor combustion, hesitation or power loss under acceleration, stalling, loss of fuel economy and increased emissions. Hope that helps some of you make an informed decision, for me if I ever leave the company I work for I would go out of my way to buy it and use in my vehicles.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. 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. The next thing you need to look out for is the key ingredients in the product. Here, the two key ingredients in stp ultra 5 in 1 are PEA and PIBA. Now, let’s see why should you take them under consideration-

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. I suggested a compression test. Results were, cylinder 1 was 80 psi, 2 was 120psi, 3 was 60 psi, 4 was 105 psi. The car had around a 1/4 tank of fuel. We added an injector cleaner and a fuel treatment to the tank. The injector cleaner does only what it says and then burns off, the fuel treatment starts at the tank, cleans the injector and inlet valve, turns to gas and cleans the combustion chamber exhaust valve EGR and Lambda of contaminants and carbon build up. The garage then road tested the car for 15 mins keeping the revs up.Redex specialise solely in producing fuel system treatments and have years of experience throughout that process.

Our advice would be to use a fuel injector cleaner on every tankful. If you strictly use premium fuel at every fill-up, you can probably reduce this to every second or third tankful. Standard fuel has a much lower cetane than that of it’s premium counterpart and has been known to create oily deposits within the fuel system so we would definitely advise using a fuel injector cleaner at every fill-up if you often use standard fuel.
