Signature Series Battles Sludge

The health of your engine depends on motor oil circulating quickly and efficiently through the system, but sticking components and obstructed passages inhibit motor oil from lubricating, cooling and protecting your engine. Engine “sludge” occurs when oxidized oil and contaminants build up on engine surfaces. It can restrict the flow of oil to the point of engine failure and costly repairs.

Sludge: Where It Starts & How It Ends

  • The valve cover and oil pan are generally the first areas sludge appears.
  • The oil pick-up tube screen is often the next spot it accumulates, impeding oil flow through the system.
  • What begins as a thin film of lacquer or varnish deposits eventually bakes into an expensive mess.

 

The Sequence VG Engine Test

Engine failures due to sludge are often caused by a clogged pick-up tube screen – the motor is effectively starved of oil. The Sequence VG Engine Test determines how well an oil resists sludge formation and keeps the lubricant flowing freely throughout the system. The test is required for API SN PLUS – a specification recommended by most domestic vehicle manufacturers.

TEST PARAMETERS

 

Engine Ford* 4.6L V-8
Duration 216 hours
Measures Sludge and varnish deposits, piston ring sticking, clogged oil pump screens and roller pin wear
Simulates Taxi, delivery or commuter vehicle service
Requirement Oil pick-up tube screen limited to 10 percent blockage

 

The Results

Signature Series Synthetic Motor Oil was subjected to the Sequence VG to measure its ability to prevent sludge. As expected, Signature Series produced an oil pick-up tube screen virtually free from sludge (see image). Our unique combination of detergents and high-quality base oils control oxidation and sludge to keep engines clean and efficient.

 

Signature Series has 50 percent more detergents1 to help keep oil passages clean and promote oil circulation. It provides 90% better protection against sludge2.

Noack Volatility

Low-Volatility motor oil helps unlock vehicle performance   To meet today’s strict motor oil specifications and adequately protect modern engines, motor oils must demonstrate increased resistance to volatility. Nearly 30 years ago AMSOIL became the first oil manufacturer in the United States to use the NOACK Volatility Test (ASTM D5800) as a measure of performance […]
