here's your Monday Morning Usless information

from your Mudflap Wearing insider :

1.0 General Information On Final Drive Oil

Final Drive oil or hypoid gear lubricant must conform

with the following requirements because of the high

loads which occur on the profiles of the hypoid gear teeth:

— Load carrying capacity.

— Sufficient protection against seizure.

— Good wear protection.

— Optimal friction and temperature behavior.

— Seal compatibility.

— Aging resistance.

These and other properties are already contained

in brand-name hypoid gear lubricants because of

the high content of EP additives (EP = extreme pressure).

Oil Additives

The factory has not approved oil additives for hypoid

gear lubricants. All final drives are designed in such a

manner that they do not require any type of oil additives.

Any type of additives is fundamentally rejected by

the factory. BMW NA cannot accept any liability for

follow-up damage resulting from the use of additives.

2.0 Approved Final Drive Oils For Front And Rear

Axle Final Drives With And Without Limited Slip Or

Viscous Coupling

Mineral based final drive oils are no longer recommended

due to the release of synthetic final drive oils for all vehicles

with or without limited slip differentials.

Limited Slip Differentials

With the introduction of the Z3 roadster a new synthetic

final drive oil for all vehicles with a multi-plate limited-slip

differential has been released. The new BMW final drive

oil SAF-XJ will replace the old final drive oil SAF-XLS.

The SAF-XLS final drive oil is not to be used in the final drive of the Z3 roadster.

Use only the SAF-XJ in the final drive of the Z3 roadster.

Note: If a non-limited slip differential

oil is used in a limited slip differential a whining or chattering sound

can be heard on very tight turns and will eventually result in

a failure of the differential.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
