Wynn’s Pre-Emission MOT Treatment – Cleaner Exhaust and Sharper Diesel Performance
If your diesel’s chucking out more smoke than it should or you’re sweating over that MOT emissions test, Wynn’s 31964 pre-emission treatment might just be your new best mate. It’s crafted to give your entire diesel fuel system a proper clean-up – from the injectors right through to the Diesel Particulate Filter (DPF) and catalytic converter. The upshot? Less exhaust muck and black smoke, which are the usual headaches diesel drivers dread.
How Does It Work?
This clever concoction zeroes in on the usual suspects behind grimy emissions – think soot and leftover fuel gunk – breaking down those pesky deposits that clog up your fuel system and injectors. By bringing fuel atomisation back up to scratch and fine-tuning the air-to-fuel ratio, it helps your engine burn fuel more completely. The result? Less black smoke puffing out the tailpipe and a smoother, nippier drive.
Why You’ll Want It
It’s not just about squeaking past the MOT. A cleaner engine means you’ll likely notice a bit more pep under the bonnet, better acceleration, and even improved fuel economy – which is always a blessing at the pumps. Plus, keeping your fuel system in tip-top shape means less wear and tear, potentially saving you a pretty penny on repairs down the road.
Simple to Use and Totally Compatible
Just pour the 325ml bottle into your fuel tank before filling up, then carry on as normal. It’s safe for all diesel engines, whether you’re running a modern common rail setup or an older pump injector system. No need to worry about it mucking around with your DPF or Selective Catalytic Reduction (SCR) systems – it’s designed to play nicely with all your emission controls.
When Should You Use It?
Whether you’re gearing up for an MOT or just want to keep your diesel ticking over nicely, this treatment is a handy tool to have in your garage. Using it regularly can keep your emissions down and your engine running sweet – especially handy if you spend a lot of time in stop-start traffic or on short runs where soot tends to build up quicker.
