frequently asked questions

Being the best in the industry comes with the responsibility of knowing the fine details of the job. So, whatever your question, we have the answer.

We don't see many 2-Stroke Motor Cycles, Scooters or Mopeds these days, why?

While 2-Stroke engines provide an attractive Power to Weight ratio, simple in design and cheaper to build, their Fuel Efficiencies are awfully low. They are bigger culprits of polluting the environment. Hence, they are being phased out.

Do I have a crankcase oil in a 2-Stroke Motor Cycle / Scooter / Moped?

No. Since a 2-Stroke Engine employs crankcase compression, it is not feasible to have crankcase oil for such engines. Instead, the lubricant (called a 2T Oil) is introduced along with the Fuel in the form of a lube pre-mixed fuel or injecting metered lube into the fuel stream entering the engine combustion chamber.

How is a 2T Engine Oil so different than a 4T Engine Oil used for bikes / cars etc?

A 2T Oil is designed to lubricate the engine components, mix-up with the fuel completely, burn and go out in the exhaust. A 4T Oil is not designed to do so. As a result, when a 4T Oil is put into in a 2T Engine, it causes spark-plug fouling, exhaust port blockage, smoke emissions etc.

Which Engine Oil should I use in my Motorcycle / Scooter / Moped?

HP RACER 2 LOW SMOKE. It is an oil meeting API TC and JASO FC to best suit your 2T Engine.

What is the oil dosage, which has to be added to the petrol?

If your motorcycle/scooter has a separate oil tank, you have to just fill the tank with HP RACER 2 LOW SMOKE. The Oil injection system in your vehicle will take care of the right dosing. In case of a premix system, 20 ml of HP RACER 2 LOW SMOKE is to be added with every litre of petrol.

What is the frequency of change of oil for the gear box of my motorcycle/scooter?

Please refer to the recommendations given in the owner’s manual as the Oil Drain Interval changes from model to model. On an average the oil should be changed every 4000 kms.

Why should not we use engine oil for diesel or petrol vehicles in my two-wheeler?

They are not designed for a 2T Engine. Hence, they will cause Spark Plug Fouling, Pre-ignition (to cause knocking), Exhaust Port/Tail Pipe blockage & would emit heavy smokes. Moreover, engine oils for other 4T Vehicles like Cars, Busses, Trucks etc., do not contain a diluent to help the oil to mix-up with petrol easily.

We have heard about some enforcement by Govt. of India for 2 - stroke oils. What is it?

In order to combat the serious pollution caused by a very large number of two wheelers in the country, the Ministry of Environment and Forests vide a GazetteNotification has stipulated the minimum level of 2 stroke engine oil as JASO FC and API TC, which is a Low Smoke Oil.

What is JASO FC oil?

JASO is Japanese Automobile Standard Organization and JASO FC is a specification issued by them for 2 - stroke 2 - wheeler oils. Over the years, a specification issued by JASO has gained importance because of its special emphasis on controlling smoke.

Why is HP Racer 2 Low Smoke is so called. How does it help controlling pollution?

HP RACER 2 LOW SMOKE is formulated with a Synthetic Component (namely a Poly-Iso-butylene) to improve lubricity and burn clean. This has resulted in avoiding Spark-plug fouling, Exhaust port/Tail Pipe Blockage, exemplary reduction in Smoke Emission, besides giving a better protection to the engine. The low smoke formula helps controlling pollution.

Which oil is recommended for the gear / transmission of my 2T motorcycle / scooter?

Generally a SAE 40 Engine oil does the job. You can use HP Laal Ghoda 20W 40/HP Gear Oil EP 90.

How is lubrication different in a 4-stroke 2-wheeler as compared to a car?

A car employs a dry clutch that doesn’t need an oil. Engine and Gearbox are lubricated with dedicated Engine Oil and Gear Oil respectively. However, in a 4-Stroke 2-Wheeler (also called 4T Motor Cycle) you have a wet-clutch, Engine and Transmission all lubricated by a common oil. Moreover, the 4T bikes operate at a far more engine rpm and power density than the cars and are generally air-cooled unlike car engines which are water-cooled. In other word, the 4T MCO is exposed to higher temperature and much more operational severity than a Car Engine Oil.

Do I need a special oil for my 4T Motor Cycle?

Yes, you need a 4T Motor Cycle Oil. Such Oil will have JASO Clutch Friction Credentials like JASO T 903 MA, MA1 or MA2 to work satisfactorily with the wet-clutch. An oil having API SJ/SL with JASO T 903 MA/MA2 would be the best bet for your Motor Cycle.

How is lubrication different in a 4-stroke Motor Cycle as compared to a 4-Stroke Scooter?

Besides lubricating Engine and Transmission, a 4T Motor Cycle Oil also lubricates the wet-clutch. Hence needs some friction in the oil to avoid clutch slippage and ensure smooth clutch engagement.

A 4-Stroke scooter generally employs a CVT belt drive and a centrifugal clutch. Hence, the oil’s work is limited to Engine and Transmission lubrication. In other word, we can have an oil with as little friction as we can.

Do I need a special oil for my 4T Scooter?

Yes, you need a 4T Scooter Oil. Such Oil will have JASO Clutch Friction Credentials like JASO T 903 MB (indicating a very low friction in oil) to yield maximum fuel efficiency. An oil having API SL with JASO T 903 MB would be the best bet for your 4T Gearless Scooter.

What is the correct way of checking Engine Oil in my car?

It is important to keep the engine oil at the correct level, to ensure proper lubrication of your vehicle's engine. Check the oil level with the vehicle on a level surface. The oil level indication may be inaccurate if the vehicle is on a slope. The oil level should be checked either before starting the engine, or at least two or three minutes after stopping the engine. Pull out the oil dipstick, wipe off oil with a clean cloth, insert the dipstick all the way into the engine, and then remove it again. The oil on the stick should be between the upper and lower limits shown on the stick. If the oil level indication is near the lower limit add enough oil to rise to the upper limit.

What is the correct way of changing engine oil in my car?

Drain the engine oil when the engine is still warm. You should change the engine oil at intervals recommended in your vehicle manual. Remove the oil filler cap. Place a drain pan under the drain plug. Using the correct spanner remove the drain plug and drain out the engine oil. The engine oil temperature may be high enough to burn your fingers when the drain plug is loosened. Wait until the drain plug is cool enough to touch with your bare hands. If possible, wear moisture proof gloves. Recycle or properly dispose of used oil as a good citizen.

Why a car needs a coolant?

When you Fuel is burnt inside the run your car engine, it produces a lot of heat. Only a part of it gets converted into power. Out of the rest of the heat, some part rejected out of the engine through the hot exhaust gases, while the balance keeps heating the engine parts. We need a radiator to keep the engine cool and continue performing.

Apart from cooling the engine, a coolant performs the following functions:

What is the correct way of changing the coolant in a car?

When the engine is warm (NOT HOT) open the radiator drain plug or remove bottom hose.

  1. Ensure your car is parked on level ground with the hand brake applied

  2. Set heater control to 'hot'

  3. Replace drain plug / radiator hose

  4. Remove radiator cap. Use a water pressure hose to flush out old coolant

  5. Put recommended quantity of HP Koolgard into radiator. Top up with water and replace cap

  6. Run engine for 5 minutes. Check water level and top up if necessary

Complete flushing and renewal of your engine coolant should occur at least every two years. Once every year engine coolant changes are desirable, if concentration is not well maintained. Most car engines have a coolant system which requires a glycol based coolant mixed with water. The glycol base acts as an anti - freeze and maintains the physical characteristics of coolant, which continuously protects your engine parts from corrosion and damage. The concentration of HP Koolgard in water should be minimum 30%, or as per vehicle manufacturer's recommendation, so as to attain complete protection.

Please check: Keep a close watch on radiator hose and fittings. A damaged radiator
hose or a loose fitting may result in leakage and overheating. Check the pressure of the radiator cap. Keep observing the change in colour of water being drained from the radiator; it can give you an indication of your engine's health.

Which coolant is recommended for my car?

HP KOOLGARD, a concentrate is recommended at 30% - 50% concentrations with water. HP THANDA RAJA is a ready to use coolant, which can be used as it is.
