This is a terrific product. I purchased a 76 series land cruiser that had the usual lifter noise at idle. I flushed the engine with oil flush, then added the heavy duty diesel treatment with new oil. The vehicle has 50,000 km on it. There is now a noticeable increase in both fuel economy and power right through the RPM range, and the engine is purring nicely. A top rate product that I will continue to use at every oil change.

Bought a Mazda 2.2 litre diesel, with some pre-diagnosed engine issues such as timing chain, & diesel to sump oil dilution. Put this in and, like with a previous Suzuki Grand Vitara 2.5 V6 petrol (also with noisy chain), this stuff smoothed out the engine, making it noticeably more quiet and powerful. I'm not big on additives but this stuff is a miracle. I'm not sure I even have to do the timing chain straight away now... just got to keep an eye on that dilution. Nice to know that nulon is in there since these things can wreck themselves at the bottom end with oil starvation, from things such as the oil pump filter-gauze getting clogged. Thanks to evil dupont and their PTFE, but mainly thanks to Nulon!

FAQs

Do I add Nulon Engine Treatments to my old engine oil or new engine oil?

Nulon anti-wear Engine Treatments based on PTFE can be added to engine oil at any time but are best added to new engine oil after an oil change. Please follow directions of use for the Nulon Engine Treatment products to ensure your engine receives the best possible protection from wear and friction.

What Nulon engine treatment suits my vehicle ?

This depends to the fuel type (petrol or diesel) and also the age and mileage on the vehicle. Worn Engine Repair (E10) for high mileage engines with some wear, Modern Engine Treatment (E20) for engines in good condition, Pro-Strength Extreme Performance Engine Treatment as a long term treatment. Diesel engines should use Pro-Strength Heavy Duty Diesel Engine Treatment.
