Just thinking aloud…maybe too much…but go down the rabbit hole with me if you will…
1974 Mobil makes M1 5W-20 oil. From what we know of this oil, it was ‘basically’ a straight 20-weight PAO oil that met 5W requirements.
Back then, J300 wasn’t the same, and cold-temp cranking tests were 5 degrees higher than today, so a 5W was tested at -25, not -30…so by todays standards it would be a ‘10W-20’ in a way.
So, HPL’s 10W-20 oil, although using different base oils and additives, is somewhat similar to the original M1 5W-20, and has similar viscometric properties.
Would love to hear some thoughts on this, especially from HPL.
