PREVENTIVE CARE

Keep caring for a car that runs well.

XADO wear-protection treatments can be considered as part of routine care for suitable, mechanically serviceable systems. Choose the product for your engine or transmission and follow its instructions alongside your vehicle's maintenance schedule.

Protect working surfaces

Explore engine or transmission wear protection even when there is no noticeable symptom.

Clean at the right time

TotalFlush is an oil-system cleaner used before an oil and filter change, when cleaning is appropriate.

Use the right interval

Treatment cycles and repeat intervals vary. A long-term wear treatment is not automatically needed at every oil change.

Preventive care questions

What about electric and hybrid vehicles?

Electric and hybrid vehicles can have oil-lubricated gears. EX120 for gearboxes and reducers may be considered where the component uses compatible gear oil; confirm the exact unit, fluid and supplied instructions. ATF, e-drive fluids and shared motor-cooling circuits need separate compatibility checks. A hybrid also has a combustion engine: suitable XADO engine wear protection can be part of its maintenance. Select by the system being treated, not just the powertrain name.

Can I use XADO if my car has no symptoms?

Yes, suitable XADO wear-protection products have a preventive-care role. Check the exact vehicle, system, fluid specification and supplied label. For a new or rebuilt engine, also check running-in instructions and the vehicle manufacturer's requirements.

Should I add it before or after an oil change?

TotalFlush is used in the old engine oil before changing the oil and filter. Plan an AMC or EX120 wear treatment so its full treatment cycle can finish before the next oil change. Follow the instructions for your exact product; do not use one timing rule for every additive.

Do I need another treatment at every oil change?

Not automatically. Follow the repeat interval on your product label. XADO's AMC Maximum 225 ml reference instructions describe a 1,000–1,500 km treatment cycle and recommend repeat treatment after 100,000 km. Check that the supplied version matches those instructions. Continue normal vehicle servicing.

Can an additive replace servicing or mechanical repairs?

No. Keep using the specified oil and normal service schedule. Severe slipping, loss of drive, overheating or an oil-pressure warning needs diagnosis before treatment.

Product Selection by Problem Solving

Tight wheel

The distinctive features and probable reasons for a tight wheel may be the following:

  • Problem: tight wheel when turning in both sides.

    Probable reasons:

    • Mechanical wear of the pump in the power steering booster system

    • Insufficient level of the fluid in the reservoir in the system

    • Mobility loss of the overload relief valve in the system

    • Low tension or wear of the drive belt in the hydraulic pump

  • Problems:

    • Steering wheel force disappears in the central position

    • Screech occurs when turning the wheel

    • Steering wheel force disappears when turning into one side

    • Steering wheel turns back into central position with difficulty

    Probable reasons: occurrence or progress of defects of the steering rack or steering mechanism gear unit.

  • Problems: tight wheel when changing the direction of wheel turning quickly.

    Probable reasons:

    • Air in the system

    • Pump productivity decrease because of wear

    • Low tension or wear of the drive belt

Recommendations

  • When the productivity of the system is decreased because of the mechanical wear it is recommended to make the complete change of the hydraulic fluid (we recommend using corresponding fluids XADO: XADO ATF III; XADO ATF III/IV/V; XADO ATF VI; XADO CHF or LHM). After the hydraulic fluid is changed the treatment of the system with one of the following XADO products is recommended: Revitalizant EX120 for power steering booster, Revitalizant for power steering booster, Atomic Metal Conditioner Maximum Diesel Truck for power steering booster.

  • When the fluid level is insufficient, it needs to be filled up. The cause of the leakage needs to be determined and eliminated.

  • When the drive belt has a low tension it’s recommended to determine the reason first: if the problem is in wear, the belt needs to be replaced; if the tension is loosen, the proper tense needs to be made.

    Note: To keep the belts in proper conditions and to provide them with the correct maintenance it is recommended to use Verylube Belt Reconditioners.

  • When occurrence or progress of defects of the steering rack or steering mechanism gear unit is found it’s recommended to repair or replace defected parts.

    Note: For a preventive maintenance of the steering wheel system in diesel trucks it’s recommended to treat it once in 30-40 000 miles with XADO АМС Maximum Diesel Truckfor power steering booster.

  • When there’s air in the system, it’s better to turn to the experts to remove air from the system and to eliminate the cause of the air inleakage.
