I suspect the marketers would rather have you rely on their claims and approvals than try to dissect the oil properties for comparison to competitors, so the less said the better. I agree I would like to see Noack instead of flash point, but splitting hairs in Noack comparison is also not very...

Flash point is a useful test for internal quality control, and is a standard reported property on SDSs for safety reasons. It is not of much use for end users for the reasons noted in posts above (except for BITOGers who use it to try to predict base oil composition 😁) .

Changes that large are most likely the result of a formulation change, but some of the difference could also come from other factors. In addition to batch variations, who reports the flash points also plays a role and that person may change from time to time. From my old post: The flash point...

Condensed from my old posts: Noack and flash point are quite different. The flash point test gathers oil vapors in the space above the oil surface, mixes the vapors with air and attempts to ignite the vapor/air mixture with a flame, so it is affected by both volatility and flammability. Test...

IMHO, the three hardest words for people to say are not "I am sorry" or "I was wrong" or "I love you", but rather "I don't know". Humans are curious and imaginative creatures with a hunger to learn and a need to know, even in the lack of valid evidence to support their theories and beliefs. This...

I have observed that people seem to have a problem comprehending three essential elements of reality: logic, probability, and time. This leads to "false facts" and a distorted sense of perspective. Without a clear understanding of facts derived from scientific methodology and logic, people...

The micro side is just as mind boggling. There are more water molecules in one drop of water than grains of sand on all beaches on earth.

My wife and I saw Disclosure Day on Tuesday. I suppose if you believe that aliens are walking among us and our leakproof government has been keeping it secret for the past 79 years, you'll probably love it. My wife does and did - I don't and didn't. I must admit though that it was well made...

"Wholesale motor oil prices are rising rapidly, and some industry executives are warning of imminent shortages caused by the war with Iran. Damage to key facilities in the Middle East and the shutdown of the Strait of Hormuz have combined to create a perfect storm in this tiny but critical...

As I understand it, manufacturers use 0W-20 oil in their fuel economy testing to get maximum CAFE benefit, and therefore must also recommend/require this grade in their owner's manual. Exceptions may be allowed for specific driving or environmental conditions, or for top-off with a return to...

I believe this video is highly sensationalized and misleading, as so many are to gain views and thereby income. Lawyers always write patent applications as broadly as possible, but that does not mean all claims will be approved, commercialized, or implemented, not to mention the flood of legal...

Those graphs look impressive, until you have a look at the X-axis.

And of course to, too, and two.

My firearms are intended for home defense, and for that purpose I consider our Ruger SP101 (DAO, .38 SP/.357 magnum, 2.25" barrel) to be the least effective. My concerns are its low capacity (5 rounds), blinding flash in a dark room, deafening blast, and heavy recoil that impacts accuracy for...
