Does Nulon have an under-bonnet applicator kit for their Lead Substitute?

How often do I need to use injector cleaning products?

For Diesel:

Pro-Strength Diesel Fuel System Extreme Clean should be used once every 10,000km.

Diesel Injector Cleaner (DIC) should be used in every tank of diesel. Treat rates are detailed on the rear of bottle.

I have been told Diesel Injector Cleaner can damage fuel pumps?

This is incorrect. Diesel Injector Cleaner (DIC) is compatable for use with all styles of diesel fuel pumps.

Is Diesel Injector Cleaner suitable for all diesels?

It is suitable for indirect injection engines (conventional) and direct injection diesels (common rail). Nulon recommend Diesel Injector Cleaner (DIC) at higher dose rate for direct injection engines

Is octane booster safe for all cars?

Yes, octane boosters can be used on all petrol fuelled vehicles. Follow the directions with regard to dose rate

Is Total Fuel System Cleaner suitable for diesel powered engines?

No, Pro-Strength Diesel Fuel System Extreme Clean is the recommeded product for diesel engines

My car is pinging. Does Nulon have a product to stop this?

Pinging can be caused by poor fuel quality or carbon build-up in engine combustion chambers. Nulon Octane Boost and Clean (OBC) can address both these problems with one treatment.

My car needs a lead replacement product to protect valves. What can I use?

Lead Substitute Valve Saver (LS) makes unleaded petrol suitable for use in older cars which were designed to operate on leaded petrol. It is also suitable for valve protection of LPG powered engines when added via under-bonnet lubricator kits.

My diesel has a DPF (Diesel Particulate Filter). Can I use Nulon Diesel Injector Cleaner in my fuel?

Yes, Nulon Diesel Injector Cleaner (DIC) is safe to use on vehicles that have Diesel Particulate Filters. It is also suitable for diesel engines that utilise exhaust catalysts and supplement treatment systems.

My diesel is blowing black smoke, what product can help this?

Black exhaust smoke is often caused by fouled injectors. Diesel Injector Cleaner (DIC), Diesel Fuel System Cleaner (DFSC) and Pro-Strength Diesel Fuel System Extreme Clean can remove injector deposits and help reduce black exhaust smoke.

What if I accidently place a fuel treatment in my engine oil?

It will dilute the engine oil, effecting its viscosity and ability to protect vital components. We recommend replacing engine oil and filter before driving.

Will Nulon fuel treatments give my vehicle better fuel economy?

By cleaning fuel system deposits Nulon fuel treatments can restore fuel economy that has been lost due to fuel system deterioration. Nulon octane boosters can improve fuel quality which can lead to increased fuel economy.

Will octane booster make my car go faster?

It will increase the octane rating of the fuel but the increase in performance will be controlled by the engine management system.
