Engine and Transmission Flush



AMSOIL Engine and Transmission Flush (FLSH) helps restore fuel economy, increase operating efficiency and reduce emissions in gasoline and diesel engines, and automatic transmissions. Its potent, detergent-based formula cleans sludge and deposit build-up, promoting reduced oil consumption. AMSOIL Engine and Transmission Flush is safe on parts and can be easily disposed of with waste oil.

Restores Vehicles to Like-New
New engines and transmissions run more efficiently, but over time they gather harmful deposits that cause power and performance loss. Stop-and-go driving, prolonged idling, short trips that do not allow the engine to reach full operating temperature, towing, the ingestion of air-borne dirt, fuel dilution, water condensation and oxidized oil all can promote sludge build-up in motor oil and transmission fluid. As it settles, sludge clogs narrow oil passages, restricting oil flow to vital parts, especially the upper valve train area.

In transmissions, deposits can form on clutch plates, causing hesitation and erratic shifting. Ultimately clutch glazing can set in, reducing the life of the transmission. Deposits in engines and transmissions can accelerate wear, causing power loss and increased fuel consumption.

  • Prepares engines and transmissions for new oil
  • Removes deposits and sludge for improved efficiency, fuel economy and lower emissions
  • Prolongs equipment life
  • Detergent-based formula is environmentally friendly
  • Compatible with seals and gaskets
  • One-treatment results
  • Easily disposed of with waste oil

AMSOIL Engine and Transmission Flush Benefits
Unlike many flush products, AMSOIL Engine and Transmission Flush features a multi-use formulation that dissolves and disperses sludge, varnish and deposits in both engines and automatic transmissions. Due to its detergent-based formulation, it can be easily disposed of with waste oil, making it more user-friendly. Its advanced formula of light base oil technology, powerful detergents and dispersants provides safe cleaning action. AMSOIL Engine and Transmission Flush is compatible with both petroleum and synthetic oils, preparing poorly maintained equipment for installation of new oil. It represents the first step toward restoring neglected equipment to top-notch performance. AMSOIL Engine and Transmission Flush provides the following benefits in only one treatment:

Gasoline and Diesel Engines

  • Helps loosen sticky valves and rings, minimizing blow-by and reducing emissions
  • Helps quiet lifter noise
  • Promotes lower operating temperatures through sludge removal
  • Easy disposal

Automatic Transmissions

  • Cleans deposits in oil cooler and ports
  • Helps unclog fluid passages
  • Cleans deposits and varnish from clutch plates, helping improve efficiency
  • Promotes smoother operation and transmission life through reduced shift delay

Applications
AMSOIL Engine and Transmission Flush is recommended for diesel and gasoline engines, and automatic transmissions. Do not use it in differentials.

Directions for Use
Though it works in one treatment, AMSOIL Engine and Transmission Flush is safe enough to be used at every oil change. If using a flushing machine, follow the manufacturer's recommendation. Otherwise, use the following guidelines:

Engine: Add entire bottle of AMSOIL Engine and Transmission Flush to engine oil fill port. Idle the engine for 10-15 minutes, then immediately drain the oil. Ensure enough time for the system to completely
drain. Remove and replace the engine oil filter. Refill engine with new engine oil in the viscosity grade recommended by the manufacturer.

Transmission: Engage emergency brake. Add entire bottle of AMSOIL Engine and Transmission Flush to transmission oil fill port. Idle for 10-15 minutes; shift through drive and reverse. Do NOT place vehicle under heavy load. Drain entire transmission and torque converter of fluid. FILTER MUST BE CHANGED prior to refilling with new transmission fluid.

NOTE: It is not recommended to flush transmissions that do not have a removable pan or access to the transmission filter.

    Awesome engine cleaner for sure!
    By  Derek,  a  Verified Buyer  from  PA  on  June 01, 2021

    Describe the issue

    I've never used this in my transmission but I've used this to prep two engines for Amsoil Signature Series. It is great for cleaning out pockets of sludge in the engine! The oil that came from my oil change in the 1987 Ford 300 was very thick and dark. I have maintained that truck engine since it was my daily driver for six to seven years.
    Bottom Line
    Yes, I would recommend this to a friend.
