Top Testimonial | from 3 DPF Doctors

Chay Blyth, Fife AutoTech Ltd

JLM Lubricants’ products are an integral part of our service. I used the DPF cleaning products with the professional DPF cleaning toolkit (100% success) on the first two vehicles. I know from experience that had they been taken to a dealership, a new DPF would have been recommended at huge cost to the customer and completely unnecessary. For example, I had a Nissan Qashqai with a severely blocked DPF. The garage referring it had removed it for cleaning. During the road test the car broke down again.

We had to work backwards on this job, cleaning the DPF before the full assessment. We used the JLM Professional DPF Tool kit and after the 3 stage process the DPF pressure came down from 2500mbar (with back pressure sensor disconnected) to 2mbar – an unbelievable result. I also use the JLM Petrol Catalytic Exhaust Cleaner, the diesel version and, the oil flush on every service.
I use the Diesel Extreme Clean for more severe issues, sticking turbo vanes and engines that are running rough due to poor quality fuel and carbon build up and am now using he JLM Extreme Air Intake Toolkit.

Whilst we have been involved in DPF cleaning with different products and brands it hasn’t always been successful. I have used many products in the past from the top brands to the cheapest. I started using JLM Lubricants’ products several years ago and after Darren’s training am
now using their Extreme Air Intake Toolkit. I was very impressed with the outcome and now I’ve gained knowledge of their products I know how to use them and can see the benefits to our business and our customers.

We’ve seen more vehicles with DPF faults during lockdown. But the DPF is not always the problem. For example, a 2012 Ford Fiesta 1.4 CDTI car that had been used for short journey driving was producing excessive white smoke. We carried out a DPF assessment which showed the DPF filter was in good health, but the injectors were sticking. We used one dose of JLM Extreme Clean followed by an extensive road test. Problem solved.

We use a wide range of JLM Lubricants’ DPF products. Which product to use comes down to what we find during the assessment. If a DPF is slightly outside of its specification, a can of the JLM Diesel Particulate Filter Cleaner added to the fuel tank along with an extended road test is an excellent way of bringing it back in line to the specification. It’s that simple.

We get vehicles in non-start conditions because the DPF is badly blocked. Here we use the JLM Cleaning Flush Pack. This is injected directly into the DPF using the JLM DPF Toolkit. This saves on labour costs because the DPF doesn’t need removing. No investment in special DPF machinery and it works every time. The products and toolkit are simple to use and little training is required.

We always advise customers on the importance of prevention. For this the JLM DPF Regen Plus is a good in tank additive to use every 7-8 weeks.
