Review: Excellent diesel additive, improves performance & starting. - 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 downside of 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.
Review: It works, thank goodness saved a fortune - I was putting a bottle of wynes dpf diesel cleaner in my car every week but dpf light came back on. I’d only had the car 3 weeks 2019 low mileage Took it to a specialist and said they could do for 2 k but may be add blue and may not solve the problem, so may have to fix that, but still not be that. felt like as a women, that garage were they taking advantage, my husband said no as not confirmed and they said may be may not be!Thought I’d give this ago. So say fill your car with 40 ltrs fuel in car, add 40ml of this stuff, every time I fill up and so far so good no light has came back on. So you may think pricey but a bottle that size will last you ages. I try I take my car out for a good run now and again. Can’t rate this stuff enough and please if you have add blue top it up as well. Never had a car with that before, so I did feel like an idiot when all the lights came on and panicked a bit. So 4 month of using this so far so darn good, so what you got to loose give it a try but make sure you wear gloves as strong smell and I keep the nozzle in a sealed bag in my boot. Hope this review helps. Just came across this old review of mine, so thought why not update it, it’s now July and still using it and can honestly say no problems since. Still on the same bottle, still loads left.

### ⭐⭐⭐⭐ Undecided if works
*by B***E on 4 April 2026*

I like the bottle and how to fill, unsure if it made much difference. Good for occasional use with a tank of diesel. Use better diesel in the first place and you won't need this.
