при 140 градусов масла мотор клина словит
Если верить маслянному фанатику то он тестирует масла на 135С и вплоть до 167С - его очень трудно читать но тем не менее
In addition to the testing at 275*F, I also tested a couple of those oils at a much higher 325*F to see how their wear protection capability might change at that temp. It turned out that their load carrying capacity leveled off and stayed approximately the same between 275* and 325*, and their ranking relative to each other did not change.
Ford Motor Company changed the motor oil spec on their 2021 High Performance V-8 Mustangs from 5W20 which had been the spec for years, to 5W30 which readers of my Blog know that I have been recommending for most water-cooled, gasoline engines for years. So, Ford has either been reading my Blog, or they independently arrived at the same conclusion I did years ago. Either way, I am proud to see that Ford and I are now on the same page.
Иногда бывает и наоборот
5W30 Valvoline Advanced Full Synthetic, GM dexos1-Gen2, ILSAC GF-6A, API SP = 115,255 psi
This oil was tested in Spring 2021.
The psi value of this new oil, which came from testing it at the normal operating test temperature of 230*F, put it in the INCREDIBLE Wear Protection Category. However, I went on to also test this oil at the much higher temperature of 275*F. At that elevated temperature, most hotter and thinner oils typically experience a drop in Wear Protection Capability. But, this was one of the few motor oils that actually produce a better psi value at that elevated temperature. This oil produced 119,289 psi, which was up by 3.5%. And that kept this much hotter and thinner oil in the INCREDIBLE Wear Protection Category.
Вообщето мы чего-то с ЕГР на масла отклонились
