AR6900-D MAX delivers a modern ester-based lubricant helping to protect high pressure injection systems and fuel pumps from today’s low lubricity, low Sulphur (USLD) fuels. Energy produced by the combustion process can be lost due to internal friction in the engine between the piston rings and cylinder walls. AR6900-D MAX lubricates these areas resulting in improved engine performance and protection, making it the perfect additive for poorly-additized bio-diesel blended fuels. ## Features - AR6900-D MAX converts low-quality supermarket diesel into high-performing Super Diesel Fuel using a carefully selected blend of pure 2-EHN cetane improver, multiple detergents, ester lubricant, stabiliser and combustion catalyst. - Suitable for all diesel engines and delivers ongoing Fuel System, Fuel Injector, DPF, EGR, CAT, Turbo and Exhaust cleaning. - Maintain engine performance and fuel economy.

For example, a 60L tank would require 60ml. **Q: can anyone tell me the mpg increase they got using this if any ?** A: I have been using this now for 8 years. My MPG has increased from 23 to 28 with a 1996 Fiat 2.5 in a 3,400 kg motorhome. That is equivalent to about 20% improvement one free gallon for every five. The first couple of doses saves the price of the complete bottle. You are effectively paid to use it. Performance is also enhanced with down gearchanges nearer the top of hills or not at all. Fuel consumption is calculated on full-tank to empty-tank miles. I can achieve 50MPH by the time I reach the end of a motorway downhill slip-way where before it would be about 40. If you're sceptical, try it - I was but I'm glad I overcame that. I've just ordered another bottle. I've just bought a Fiat Doblo 1.9 diesel - I'll try it in that next. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent diesel additive, improves performance & starting. *by on Reviewed in the United Kingdom 7 July 2026* Excellent additive, been using Red x diesel in every tank since I bought my car, was recommended to by dealer. Was an ex demo SUV, had car 10 years, 2.2d turbo intercooler, 178PS , usually get 48 mpg per tank, car can do 0.60 mph in 9.9 seconds though rarely have I attempted that!! lol Keep car serviced annually as per manufacturers service schedule.Kerb weight is 1700kg without driver, a fairly heavy car, performance & economy has always been outstanding, in my opinion, hence decided to keep this car until it starts costing too much for servicing. As Red x seems too expensive now, thought I'd try something else, read reviews on here, and decided upon Archoil AR6900-D and I'm not disappointed.Archoil AR6900-D is exceptional, in my opinion, whilst I wasn't looking for more performance, I've got it, feel like I've suddenly got a sports car. For my car it worked instantly, been overtaking everything in sight. So easy to use, was going on a 200 mile journey, so thought a good test for this. So simple and easy to measure via a cap within a cap, I.E., the outer cap unscrews which is essentially a cover for a nozzle, pour it in then add fuel like I used to do with Red X.As this is my first use of this over a fairly decent journey, I'm ditching Red X, that's for sure, I used more fuel, as was enjoying the overtaking and acceleration so much. The journeys economy dropped to 45 mpg, still acceptable to me, as enjoyed the extra performance, and the engine feels more smooth and quieter.As some other respondents have mentioned, starting a diesel can be an issue, that's been the only downsideof this car, it's never liked starting from cold, always starts first time after engine warmed up, had similar issue on all previous diesels, though not as bad as this one. Usually takes at least 2 attempts in summer, 3-4 in winter.Was same when new, was informed about this by the dealer, have to let car idle for 5 mins also before driving also to allow oil to lubricate the turbo, have started from cold several times since adding Archoil, and it starts first time every time.As of writing this in UK in July 2026 it is hotter than usual for us in south England,and it did used to start better when hot outside, but it has never started first time before. The real test will be winter, but any improvement will be helpful. Rather than needing a new costly battery every 2 years, if this helps starting as much has it has already, I'll be saving loads of money, it's also possible this additive may even extend the life of the car. ### ⭐⭐⭐⭐⭐ Great product *by on Reviewed in the United Kingdom 3 September 2026* Works well. My car initially had some more frequent DPF regenerations when I first added it and had now gone back to normal frequency. The regenerations don't seem to last as long either, which is good. The car is running smoother and quieter too. The bottle is a little confusing to use and if you need to put two treatments into one tank, it can be a pain to take the nozzle off, invert the bottle and put it back on again. It means you get the product on your hands, although it's pretty easy to clean it off. Overal a great product though, and great value for money given the amount of treatments you get out of one bottle. ### ⭐⭐⭐⭐ Diesel DPF cleaner *by on Reviewed in the United Kingdom 17 September 2026* A good product has improved performance on my vehicle easy use clear instructions quick delivery --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hu/products/50719139-archoil-ar6900-d-max-advanced-diesel-additive-concentrate-500ml](https://www.desertcart.hu/products/50719139-archoil-ar6900-d-max-advanced-diesel-additive-concentrate-500ml) --- *Product available on Desertcart Hungary* *Store origin: HU* *Last updated: 2026-09-29*
