Red Flow Diesel & Petrol Additive | Injector Cleaner (300ML), Treats 60L Diesel & 150L E20 Petrol, for All Cars, Bikes, Scooters. Keeps Engine Clean, Improves Engine Smoothness, Fuel Economy.

I’ve been using Red Flow Petrol Additive in my Royal Enfield Himalayan Scram 411, and the results have been genuinely impressive. After a few rides, I noticed the engine running smoother with better throttle response, especially in low and mid-range RPMs where the Scram is used the most. The bike feels more refined, with reduced engine knocking and vibration, making both city rides and longer highway runs more comfortable. Cold starts are smoother, and the overall combustion feels cleaner. There’s also a slight improvement in fuel efficiency, which is a nice bonus. What I really like is how the additive helps keep the fuel system clean and maintains consistent performance, which is important for a bike like the Scram 411 that’s built for mixed riding conditions. It’s easy to use and blends well with regular petrol without any issues. Overall, Red Flow Petrol Additive has been a great addition to my Himalayan Scram 411. It enhances performance, protects the engine, and makes the ride feel more refined. Highly recommended for Royal Enfield owners who want smoother performance and better engine health.

Good Product must buy.

The Reflow Fuel Additive delivered a clear jump in mileage, which was the biggest and most noticeable improvement. Fuel efficiency increased enough to reduce refueling frequency. Engine performance also improved. The car feels smoother, and pickup is quicker and more responsive. Verdict: Strong mileage boost with better overall driving feel. Worth it.

I am riding Speed 400 and covered 11,000 km so far. I was having missing issues and less throttle response. And I was getting some vibrations and sound from bike. Fuel pump was never cleaned before, I was planning to clean it during second service. I thought I will give this try before that. And it is absolutely amazing! Value for money 5/5 You are getting 300 ml of the product, you only need to use 3ml per litre of petrol, that means this will last for 100 litres of petrol. And you don't need to use it very often. Very straight forward to use, I just filled my tank fully, whis 13 litres. 13×3=39ml for one use. And I am seeing results very quickly.(Within the first 30km) I have no missing issues now. Throttle response is like how I had it when I received the bike brand new! Also the vibrations are gone now! While idling bike is smooth. And engine sound also gone! Also I have noticed slight increase in mileage too. These guys are living upto their word. I am 100% convinced that this protects my bike from buildups in fuel lines and filter Packaging might look cheap, but This is a PREMIUM PRODUCT!! So happy with my purchase!! 5⭐

My Experience with This Diesel Additive (2015 Skoda Rapid TDI): I dumped a full bottle of this stuff into my full tank and here's what happened: The Good Stuff: - My car instantly felt smoother on the road - The engine got WAY quieter (like, seriously noticeable) The Not Great Part: - Here's the big issue - my car lost its punch - You know that quick boost you need when overtaking? Yeah, that's gone - Thought it would get better after driving a while, but nope... quarter tank later, still the same problem About the price - it's definitely on the expensive side. Should you buy it? Honestly, if you're tired of engine noise and want a smoother ride, maybe. But if you like your car's power (especially for overtaking), I'd think twice. I'm giving it 3 stars because while it did make my car run smoother and quieter, I really miss that power. Plus, it's pretty pricey for what it does.

Honestly, when I first read the reviews for this product, I wasn’t fully convinced. Still, I decided to give it a shot—and wow, I was wrong to doubt it. This product is genuinely impressive. It doesn’t boost mileage drastically, but you will notice the difference. The engine feels smoother, and after using it two or three times on a full tank, the improvement was clear (if you pay attention to how your car runs). I tested it on both my cars—one Honda and one Hyundai, both petrol (one automatic, one manual). My dad drives one, I drive the other, and we both felt the positive change. What I also like is that it’s cost-effective—you don’t need much of it per full tank, so it feels worth the money. I’d recommend using it especially if your car has crossed 40,000 km, and then repeating it every 2,000–3,000 km or whenever you fill up. With the new E20 fuels, I think this is almost a must-have since it seems to clean the engine from the inside (I can’t confirm scientifically, but the difference is noticeable). And the best part? Even if you stop using it, the mileage improvement stays. Overall, I’d definitely recommend this product.

Best work on bs6 car still it works on bs3 bike. Pick up improves. Also positive effect on mileage. 4 star for its high price. Price shuould be @400 max

I’ve been using Redflow petrol additive for the past 6 months on my Royal Enfield Himalayan BS6 (non E20 compliant), and the results have been genuinely impressive. Before using it, I was facing multiple issues unstable idle RPM, frequent stalling in bumper-to-bumper traffic, noticeable throttle lag, and engine overheating. An OBD scan showed no errors, which meant there was no need for expensive replacements like the throttle body or fuel pump. Interestingly, the bike never stalled under throttle it was purely an idle-related issue, making city riding quite frustrating. Since I started adding Redflow consistently (around 2 ml per litre at every refuel), these problems have almost completely disappeared. The idle has stabilized, stalling is gone, throttle response feels smoother, and overall engine refinement has improved. The biggest proof came during my Mumbai to Ratnagiri ride (around 375 km), where the bike delivered an impressive 37 km/l excellent for a 411cc air-cooled engine running on E20 fuel. Overall, Redflow has been a simple and effective solution that saved me from unnecessary part replacements and significantly improved my riding experience. Highly recommended for BS6 bikes facing similar issues.
