Special Notations:

Viscosity:
A 5% application of NNL 690 in typical SAE 30 to SAE 50 weight oils results in little or no change in viscosity or viscosity index of the oil.
Pour Point:
NNL 690 is formulated to have a negligible effect on the pour point of typical engine oils.
Alkaline Reserve:
Power Up NNL 690 is blended with an acid scavenger to neutralize blow-by gases and acidic oil degradation products. The addition of 3% NNL 690 will increase the base number of engine oils by about 0.5 mg KOH/g.
Application:
NNL 690 is intended for use in engine crankcases at 3% of the oil volume, each time the oil is changed. It can also be used in automatic transmissions at an application rate of 1%, power shift transmissions at 3% and in circulating systems at 3% to 5%, depending upon operation conditions. NNL 690 is compatible with all mineral oils and polyalphaolefin and diester based synthetic oils. NNL 690 is not recommended for use with water based fluids, phosphate esters or polyglycol fluids.

Power Up NNL 690 is a unique boundary lubricant which is specifically formulated to solve many of today's tribological problems in the boundary lubrication regime. NNL 690 works by forming a wear reducing, protective film which is capable of withstanding extreme pressures. NNL 690 provides critical engine parts, such as the ring zone, cam lobes and turbocharger, with boundary lubrication protection far exceeding that of conventional oils. NNL 690 is a carefully balanced, complete additive package which contains anti-wear and extreme pressure additives, detergent/dispersants, viscosity index improvers, corrosion inhibitors and acid neutralizers.

Boundary Lubrication Protection:

In independent Contact Gamma wear tests, NNL 690 significantly reduced the amount of wear generated when an engine oil alone was used. The results are provided graphically in Figure 1 below. Calculated estimates based on wear reduction (up to 86.9%) suggest that the use of NNL 690 can extend equipment life over 7 times by reducing wear up to 86.9%.

Diesel Engine Field Test:

A series of dynamometer and ultrasonic noise tests were carried out by an independent consultant to determine the effect of Power Up NNL 690 on a diesel highway tractor engine. The application of 3% NNL 690 increased the horsepower and torque, while reducing fuel consumption, ultrasonic wear noise and emissions. Some of the computer controlled and corrected dynamometer results are given in Figures 2 and 3.
