Это конспирология: «@Admin обесценивает глубинные-МП-идеи LSPI (с особым цинизмом), чтобы вывести LSPI из расчета, чтобы лох педальный...

@Nesae назвал эти «убогие старинные минералки» (забитые побелкой) - типа 10W-40 и 15W-40 - «очень простыми». Без негатива. Я бы назвал...

что это? По каким данным они "сопоставимы"? Не по ppm химических элементов, надеюсь? Ведь по протонам, нейтронам и электронам - вообще...

Да это скорее минус, а не плюс :) Полярность в гидродинамике - минус.

https://oil-glup.ru/threads/obschaja-istorija-pcmo.269/page-3#post-11123 The corporate logo for Lubrizol appears centered on a plain white background in dark gray sans-serif lettering with a lowercase dotless i. A thin blue curved underline sweeps beneath the brand name, slightly tapering at both ends. Below the sweep, the company tagline reads Imagined for Life. Enabled by Science. with a small trademark symbol placed at the end of the sentence.

It lists viscosities at 100 °F, 130 °F, and 210 °F, alongside KVI, pour point, and SAE grade values. Explanatory text below notes that these petroleum oils meet government specs for naval use, while the Ucon fluids and SS-903 or SS-906 polyethylene oils represent early synthetic lubricant development.

A bold red block letter M dominates the center, overlaid with yellow text reading Macmillan Royal Scot and Motor Oil alongside volume details of 32 fl oz or 1 US qt at the bottom. The steel top lid shows embossed text circles and light wear around the rim from past handling.

https://oil-glup.ru/threads/est-li-minusy-u-mineralki.100/page-3#post-11103 An old Shell motor oil print ad features the Shell Answer Man beside three quart cans including X-100 Multigrade 10W-20W-40, X-100, and Shell Super X 10W-50. The bold headline asks whether oils made from Pennsylvania crude oil perform better, answering that refining quality and additive packages matter far more than crude source. Text guides buyers toward meeting SE service classification requirements and selecting proper multigrade viscosity ratings for heavy-duty driving or all-weather use.

The layout maps out a grid of numbered exhibitor booths, alongside specific zones like conference tracks, networking lounges, media lounges, and exhibitor services. Major companies and various smaller suppliers occupy the floor space, with an entrance at the bottom and a dining area at the top left.

https://oil-glup.ru/threads/est-li-minusy-u-mineralki.100/page-3#post-11077 A vintage promotional text asks and why does it have all these qualities before explaining that Macmillan Ring-free oil gets its unique performance from specific crude and a patented refining process. Instead of blending standard neutral and bright stock like competitors, Macmillan uses fractional distillation to split hydrocarbons for different SAE viscosity grades. The page concludes that this method yields a pure, unadulterated lubricant completely free of chemical dopes, additives, or compounding.

https://oil-glup.ru/threads/macmillan-ring-free-motor-oil-sae-20-unikalnoe-naftenovoe-mineralnoe-maslo-1940-goda.309/#post-11073 A 1942 print advertisement for Macmillan Ring-Free Motor Oil lays out a seven-step fried egg test to prove the lubricant removes carbon deposits. The black-and-white layout pairs numbered instructional panels showing evaporating dishes with promotional copy explaining that the patented refining process dissolves carbon binders. Honestly, it is a brilliant piece of marketing that turns basic bench chemistry into a compelling pitch for engine longevity.
