PRODUCT DESCRIPTION

AMSOIL Shock Therapy Suspension Fluids are formulated for maximum stability and high performance. High quality synthetic basestocks and high viscosity indices provide unparalleled shear stability. AMSOIL Shock Therapy Suspension Fluid controls friction and heat, reduces wear and scuffing and prevents fade more effective than conventional fluids can. AMSOIL Shock Therapy Suspension Fluid has been tested in the lab and against the competition and proven to be of the highest quality at a wide range of temperatures and applications.

Controls Dampening and Rebound

With AMSOIL Shock Therapy Suspension Fluid, viscosity remains constant and aeration and foam are greatly reduced, significantly limiting shock fade and inconsistent dampening. AMSOIL Shock Therapy Suspension Fluid (STL & STM) is formulated for fade-free dampening and smooth rebounds in many racing and recreational applications, reducing rider fatigue and enabling the driver to ride longer and harder while keeping focused on the terrain ahead.

Reduces Friction and Wear

Constant friction in a shock body decreases suspension performance while causing scuffing and wear on the inner walls. AMSOIL Shock Therapy Suspension Fluid contains friction modifiers to reduce frictional energy loss and heat buildup. Anti-wear agents protect against premature scuffing and wear, while maintaining proper suspension absorption.

Temperature and Performance

AMSOIL Shock Therapy Suspension Fluid features high pour and flash points, maintaining its ability to provide superior protection in both high and low temperature extremes. It is highly resistant to volatility, avoiding breakdown and resisting the buildup of sludge and deposits. 

Maintains Seal Pliability

AMSOIL Shock Therapy Suspension Fluid includes seal conditioners, keeping seals soft and pliable and extending their service life.

Recommendations

AMSOIL Shock Therapy Suspension Fluid is recommended for front forks and shocks in snowmobiles, motocross and cruiser motorcycles, ATV's and other racing and recreational use vehicles. Two different formulations are available: The lightweight grade (STL) is recommended, but not limited to, Showa, Kayaba, Bilstein, RydeFX, Penske, WP forks, RACETECH (US1) and Custom Axis suspension systems that demand quick rebounds under extreme hot and cold weather applications, while the medium grade (STM) can be used in Ohlin, FOX, RACETECH (US2), Koni, WP shocks and Harley-Davidson forks that recommend type "E" or "B" fork oils, as well as other applications that require more dampening and slower rebounds. Refer to the owner's manual for individual capacities, proper disassembly and further recommendations. Owner's manuals may refer to weights when recommending suspension oil. These weight numbers are arbitrary because no industry standard exists for classifying suspension oil. The numbers can range from 2.5 to 30, depending on the manufacturer. AMSOIL STL correlates closely to a 5 weight, while AMSOIL STM is close to a 10 weight.

Compatibility

AMSOIL STL and STM can be mixed together based on individual requirements and applications, and they are compatible with most other suspension fluids.

Product Availability

AMSOIL Shock Therapy Suspension Fluids are available in quarts and 5-gallon pails.

Peter Virgona of Merrick, NY is a self-proclaimed oil enthusiast.

“I do a great deal of reading and research, always looking for the best oil,” Virgona said. “The more I read the more I realized AMSOIL was the best ‘true’ synthetic I could buy. After using Mobil 1 since 1986, I made the switch to AMSOIL.”

Virgona drives a 1999 Ford Crown Victoria with nearly 98,000 miles on the engine. He switched from Mobil 1 to AMSOIL 5W-30 Synthetic Motor Oil.

“The difference was immediate and signifi - cant,” Virgona said. “The idle became much smoother. There are times I can’t tell if the car is running. It also became much more responsive to the gas pedal, so much more responsive my wife asked me what I did to the car.”

He has owned the car for almost nine years. “Not surprisingly, the gas mileage improved signifi cantly,” he said. “This car always averaged 15 mpg going back and forth from work. It now averages 16.5 mpg. That’s a 10 percent increase. I truly didn’t expect such a big change.”

He waited to report his fi ndings until after he had driven the car at least 5,000 miles “to confi rm that the numbers are average and not just a fl uke.”

Virgona also installed AMSOIL 5W-30 in his sister-in-law’s 1996 Dodge Caravan with a 3.0 litre V6 engine. She had always used conventional motor oil with regular oil changes every 3,000 miles, Virgona said.

“Nonetheless, she had a signifi cant amount of sludge that was obvious under the oil cap,” he said. “She also experienced a very loud lifter noise that would come and go with the engine either hot or cold. Presumably the sludge was affecting the oil circulation to the lifters.”

Oil consumption in the van was increasing, using about one quart every 1,500 to 2,000 miles.

“I switched her to AMSOIL and put in a new fi lter,” Virgona said. “Within 1,000 miles the lifter noise was all but gone. By 3,000 miles, virtually all the sludge was gone. I drained and refi lled the oil a second time with AMSOIL 5W-30. The oil consumption is now down to one quart every 3,000 miles, with no more lifter noise. And, except for a little yellow varnish, all the sludge is gone.

“I am very happy with AMSOIL and plan to use it from now on. I recommend it to anyone who wants a great synthetic oil.”

Virgona just had a case shipped to his father-in-law in Florida because he believes in AMSOIL products, he said, and wants others to experience their benefi ts. In fact, he’s considering becoming a Dealer. The more I read the more I realized AMSOIL was the best ‘true’ synthetic I could buy.
