I’ve been using Hybrogen every tank on my old 2004 Merc ML270CDI and I am very impressed.
It does all the things you say and has more power for sure. I decided to change the glow plugs last week and on my engine they are renowned for sticking in and breaking so I was somewhat nervous - but I had been giving constant doses when refilling of about 1:2000 so a bit rich maybe but all the glowplugs came straight out and were clean as per photo. The liquid on the glowplug were from dosing the threads with deblock fluid.
So, clearly my engine is a lot cleaner inside.
Hi, I would just like to say I was a bit sceptical about the Archoil additives but as my wife's Astra 2.0 DTi with 18,700 miles on the clock needed a fair bit of work, engine management lights - EGR problems, Injector problems, flat spot on turbo and a loud diesel knock I thought what the hell give it a go and purchased your Diesel Service Pack. No immediate improvement, however after 7 days - WOW! No flat spot on turbo, no more engine management lights - EGR fine, Engine really smooth and no diesel knock! The old girl is driving like NEW, no hesitation and loads of torque.
Can't believe it especially after using the likes of STP and Wynn's. You definitely get what you pay for, and I have recommended it to my friends and family. I will be ordering another service pack shortly for my trusty Peugeot work van.
