BARDAHL 142023 B2 OIL TREATMENT 300 ML - Engine Oil Additive, reduces oil consumption and blue exhaust smoke

Capacity: 300 ml

BARDAHL 142023 – B2 OIL TREATMENT 300 ML

Bardahl B2 Oil Treatment is an engine oil additive that Bardahl classifies as a "curative treatment". It is added to the engine oil when a petrol or diesel engine burns too much oil, produces blue exhaust smoke or loses oil pressure when hot. It suits both drivers who want to treat their own car and workshops that offer it at service time.

What it is for

Bardahl recommends B2 for these problems:

• Excessive oil consumption and blue exhaust gases: the engine is burning oil.
• Low oil pressure: hot oil loses viscosity.

Among the possible causes, Bardahl lists oil getting past the piston rings and fuel contaminating the oil, which lowers its viscosity.

Benefits

• ✅ Increases engine oil viscosity at high temperature.
• ✅ Helps the oil maintain pressure at high temperature.
• ✅ Increases the load-bearing capacity of the oil film.
• ✅ Improves engine efficiency and the oil's anti-friction and anti-wear properties.
• ✅ Reduces exhaust smoke caused by burning oil.
• ✅ Exclusive Bardahl Polar Plus formula.

Dosage and directions

Add B2 directly to the engine oil at 5% to 10% of the oil capacity (Bardahl's guidance). For example, a 4-litre sump needs 200 to 400 ml of product, so the 300 ml bottle covers most car engines. Do not exceed the maximum oil level on the dipstick.

Technical specifications

• Bardahl code: 142023
• Product: B2 Oil Treatment, engine oil additive
• Size: 300 ml bottle
• Dosage: 5–10% of the oil capacity
• Engines: petrol and diesel
• Technology: Polar Plus formula
• Treatment type: curative

Compatibility

Bardahl states that B2 is suitable for all petrol and diesel engines. It works on the oil, increasing its hot viscosity and the strength of the oil film.

When it is not enough: B2 does not fix mechanical faults. Broken rings, a damaged head gasket, a turbo leaking oil or external oil leaks (seals, sump) need a workshop repair. If oil consumption is very high or appears suddenly, have the engine checked first.

• Bardahl 147023 Engine Tune-Up 355 ml, engine cleaner
• Bardahl 140018 T&D Additive 250 ml, gearbox and transmission oil treatment
• Bardahl 160023 Radiator Stop Leak, radiator leak sealer

Frequently asked questions

What is Bardahl B2 Oil Treatment for?
Bardahl B2 is a curative engine oil additive. It increases oil viscosity at high temperature and reduces oil consumption and blue exhaust smoke in engines that burn oil.

How much Bardahl B2 should I add to the oil?
Bardahl indicates 5% to 10% of the oil capacity. With 4 litres of oil you need 200 to 400 ml; with 5 litres, 250 to 500 ml.

Is Bardahl B2 suitable for diesel engines?
Yes. Bardahl states that B2 is suitable for all petrol and diesel engines.

Does Bardahl B2 stop blue exhaust smoke?
Bardahl states that B2 reduces exhaust smoke caused by burning oil. If the smoke comes from a mechanical fault, such as broken rings or a turbo leaking oil, the additive will not solve it and a repair is needed.

Does Bardahl B2 raise oil pressure?
Bardahl indicates that B2 helps the oil keep its pressure at high temperature by increasing its hot viscosity. If the oil pressure warning light comes on, stop and have the engine checked: the cause may be the oil pump or the oil level.

Does B2 repair a worn engine?
No. B2 improves the oil's properties but does not replace worn or broken parts. It helps engines that burn oil; it is not a mechanical repair.

What is the difference between Bardahl B2 and Engine Tune-Up?
B2 (142023) is added to the engine oil to increase its hot viscosity and reduce oil consumption. Engine Tune-Up (147023) is an engine cleaner. They meet different needs.

Can I use B2 in gearbox oil?
B2 is formulated for engine oil. For gearboxes and transmissions Bardahl offers T&D Additive (140018).

When should I add B2?
When you often have to top up the oil, when you see bluish smoke from the exhaust, or when oil pressure drops with a hot engine. You can also add it at a service together with the new oil, keeping to the 5–10% dosage.

Is the 300 ml bottle enough for my car?
With a sump of up to 3 litres, 300 ml is the maximum 10% dosage. With a 4–6 litre sump it falls within 5–10%. For larger engines check the oil capacity in the owner's manual.
