Tec4 Technically Advanced DIESEL SYSTEM CLEANER

My Jeep 2.8crd was going into limp mode on hard acceleration with over and underboost faults recorded. I put a bottle of Tec4 in a full tank of fuel and the improvement was soon noticeable. I did follow up with a 2nd dose but I believe the initial treatment was sufficient.

My old saab estate 1.9tid diesel was giving me a problem; it seemed to be permanently regenerating the dpf, also when I started the engine in the morning, blue smoke everywhere, and a whooshing noise when I pressed the gas pedal, oh, and yellow engine light. A mate said the turbo's had it etc.I've used dpf cleaners before, some work some don't, then I saw this stuff, can be fatal if swallowed, hmmmm, it must be strong? I put it in with £20 of diesel, day one no change, day two I thought I had a new engine; engine light off, no smoke when starting, smooth power delivery, no whooshing noise, even the fuel economy has increased by 2 to 3 mpg, no regeneration smoke everywhere, fan bloody tactic!I'm only on day 5 but still great, I highly recommend it

….cleared my yellow warning light and‘cleaned’ the DPF but not much improvement in mileage and the good effects didn’t last long. That said it’s worth the money.

Probably one of the better products I have purchased for my diesel car.

Did it's job...car performing well
