Mobil 1 History ?

[Tom NJ]

Hi Toocrazy,

Yes I am familiar with aircraft turbine oils - I formulated them at Hatco. I just never heard of a "blue" one.

Like most any independent lubricant manufacturer, they need to purchase their raw materials from some source. If it were ever confirmed beyond word of mouth that Amsoil gets ALL of their raw materials from Exxon/Mobil, or any at all, then that would be interesting.

The difference would be in the SEAL CONDITIONERS that are now employed.

Yep, the oil used in GE turbine engines in our F/A-18 jets is colored blue. I suspect it's merely a dye intended to help spot leaks just as our hydraulic fluid is colored bright red.

Maybe I could try it out in an old lawnmower.

Hi Allen,

All of the aviation turbine oils will appear to have a bluish tint when viewed in sunlight or under ultraviolet light due to one of the common additives, and if left in a clear bottle exposed to light will develop a permanent redish blue color. That said, no fresh sample should appear blue under normal room lights. Perhaps you are viewing the color while pouring in sunlight? I would be interested to know the label information if available.

I'll see if I can steal a can from the mechs.

You are correct in saying that the original Mobil One was a 5W-20. It was said to be the equivalent of 10W-40 in a regular oil. I only remember the 25,000 mile OCI claim, with the one year limit on time. I took them at their word, and used it in my vehicles at a one year or, usually, 18,000 to 20,000 mile OCI. Never had a problem from the 70's until I retired in 2001. Always changed my oil in January. Usually had to add 2 or 3 quarts in 18,000 miles.

This is, I heard, the reason they quit advertising the 25,000 mile OCI. Some people were not checking their oil level and letting it get low and ruining their engines. As far as I know, they quit advertising the 25,000 mile OCI many years before GM began using it in some of their autos.

A question I have added to several of my posts here on BITOG is: What has Exxon done to their M1 to make their extended OCI version good for only 15,000 miles?
