What do you all think is the most robust/stout off the shelf oil in a 20/30 weight, excluding HDEO.
Thought that come to my mind...ML Syn, ML Blend, M1 HM..
your thoughts? Interested to see what everyone has to say!
Castrol HM 10W-30. Starts at 12.1 cst, and goes on in adds about how it 'resists burn-off better than other oils' etc....
Have seen at least one UOA where it held a thick 30-weight visc. over 4.5k miles and one year.....
Robust in what way? There are racing oils that are robust in anti-wear additives but weak for longer drains. There are oils that are good for long drains but are SM rated so lower additives.
Are you meaning in terms of long drains, additive wise or some middle ground not yet defined?
Amsoil is a bit pricey but their Signature Series (SSO), is the the cream of the crop in my opinion. I really like their products and extended drain intervals that are possible. I don't run it as long as they claim it's good for, but I always get fantastic UOA's from it.
I'm thinking of trying PP after I use up my Amsoil stash, to see what the numbers are in comparison to my Amsoil runs, because if I can get as good of UOA's as others on this board but with a cheaper-cost product then I will switch.
Just my 2 cents! :)
Redline 5W-20 is the best 30 weight oil I've used.
That gem is quote-worthy!
Here's a recent one from my cam grinder:

There is a right way which requires work or the wrong way for those who simply don't know.
