|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
lower operating temperatures and reduced oil consumption.

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 airborne
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.

• One-treatment results
• Easily disposed of with waste oil
Installing new oil or transmission fluid into a dirty
vehicle may not be enough to remove deposits and
increase efficiency. The detergents and dispersants in
some lubricants may not be able to handle leftover
sludge and deposits, and the new lubricant soon
becomes unfit for service, accelerating the formation of
even more harmful deposits.
AMSOIL Engine and Transmission
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, used AMSOIL
FLSH 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 FLSH 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
• Easy disposal
• 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
AMSOIL Engine and Transmission Flush is recommended for
diesel and gasoline engines, and automatic transmissions. It
is not recommended for CVT transmissions or 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
Engine: Add 16 oz. 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 16 oz. 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.
