15W-40 means it's gotta be 3.7 or higher, it's somewhere in the 4.1 - 4.2 range if i remember correctly, which is about the normal for a 15W-40 HDEO.

Thank you, it seems that most oil companies won't give HTHS specs for their oil.

Is this the same for API certified oils?

ACEA has hths >3.7 for the 15w40....

Ocording to VOA subforum here....oils from over the pond all tend to have lower hths numbers...

I'm quite sure? 3.5 for 0W,5W,10W-40 and 3.7 for 15W,20W,25W and SAE 40 correct?

Ofcourse they don't.
We, those who know what HTHS among other things, are 0.1% of their customers, not even that probably, why disclose it if 99.9% of people don't even know what it is.

Your generator will love it.
Generators run at constant rpm or close, in consistent environment. Just about anything will be fine in there. If it's fine in a turbo charger diesel for 10,000 miles it's fine in a generator for 80-100 hours.

Found these stats online. Unfortunately, many popular oils aren't on this list:

HTHS - High temperature High shear A relatively new oil test/specification, the oil is subjected to high temperature 150C and is mechanically sheared at 1 x 10^6 per second. A value of 2.8 or is considered the minumum for normal bearing wear. Here are some HTHS numbers on well known oils, the higher the number the more shear stable the oil; 4's and 5's are excellent numbers and demonstrate basestock quality e.g. Silkolene and Motul.

Mobil 1 0W40 HTHS 3.6

Castrol RS 10w-60 HTHS 3.7

Castrol RS 0w-40 HTHS 3.7

Silkolene PRO S 5w-40 HTHS 4.07

Motul 300V 10w-40 HTHS 4.19

Motul 300V 5w-40 HTHS 4.51

Redline 5w40 HTHS 4.6

Redline 10W40 HTHS 4.7

Mobil 1 15w-50 HTHS 5.11

Silkolene PRO S 10w-50 HTHS 5.11

Silkolene PRO R 15w-50 HTHS 5.23

Motul 300V 15w-50 HTHS 5.33

Redline 15W50 HTHS 5.8
