There have been a few threads lately about the best dino oils, or the oils you would never use, etc.

It got me thinking, what are some of the strongest, most robust oils out there? Synthetic or dino, it doesn't matter. Let's keep HDEOs out of the discussion though. We all know the Delos and Rotellas of the oil industry are pretty strong.

Mobil 1 TDT/Delvac 1 5w40. Doug Hillary was doing 90-100,000Km OCI's on Delvac 1 in 500HP OTR trucks through the Aussie Outback.
 
In 30 grade:
Mobil 10W-30 HM.......................3.66 HTHS, HD add pack
Valvoline MaxLife synthetic 10W-30....3.60 HTHS, HD add pack
Valvoline MaxLife blend 10W-30........3.30 HTHS, HD add pack

In 40 grade:
Mobil 1 10W-40 HM.....................4.1 HTHS, HD add pack
Valvoline MaxLife blend 10W-40........3.5 HTHS, HD add pack

Both the Mobil 1 and the Valvoline oils have heavier base oils, extra boron, and extra antioxidant. The Mobil 1 oils have 1000 ZDDP and about 100 moly. The Valvoline oils have 800 ZDDP and 300 moly. Both advertise extra cleaning, but both have the same calcium, magnesium, sodium as their non HM oils. It has been guestimated that it is ester or amines.

Amsoil 10W-40 XL is most certainly a robust oil and an inexpensive oil. Valvoline 10W-40 Durablend, Valvoline 10W-40 Premium Conventional. All these would qualify, are not HDEO/diesel, and you can get all but the Amsoil at Walmart.

On up there is Mobil 1 15W-50, 1200 ZDDP, lower pour point than some 30 grades, fantastic 40C of 131.2, 100C of 18.1 and HTHS of 4.5. I use it in all road vehicles year round.
 
High-Temperature High-Shear viscosity, which is resistance to flow in the main bearings. That value is important in severe service like trucks towing/hauling heavy loads at highway speeds, and racing.
