For years I've used t6... The last time I poured it in my rig, I screened chunks of junk out of it. Had I not been using a funnel with a screen, I'd never have known it. Add to that the silly high aluminum counts the uoa return, and that ought to be enough warning for me.. so.. t6 is out.
Searching for a new oil that will suit my needs, and my God are there choices and all grades of places to fall into a rabbit holes never to return.. but, I pulled the trigger.
The final four choices were amsoil 15/40, red line 15/40, mystik 15/40, and Schaeffer 15/40.9000...
The mystik, though a bargain brand, is apparently highly regarded and works really well in an engine that doesn't have emissions crap... It meets required ratings, and supposedly has shear strength of some group three oils... It's a good buy, and something I wouldn't hesitate to put in a fleet truck I intended on stacking hard miles on, running strict service routines on.
The amsoil, no matter how prestigious, doesn't have a certifying rating... And that worries me.. it's all about consistency from batch to batch, and with nobody looking over their shoulder, maintaining that consistency is solely up to them..
Red line was my second choice.. it's high dollar stuff, and great for extended intervals. It has a magnesium compound that provides ridiculous shear strength (film) which is great for protecting hot spots such as rings and rocker tips.
I went with the 9000 Schaeffer's. It has all of the finer points of the others, plus 3 free oil analysis's..
I'll report back what my engine thinks of it in 5k miles... I think, on paper, this is the better choice for me. I should have added in royal purple as well, as that one (believe it or not) was on the final list too.
Point is, though, watch your reports on the T6... If you see high aluminum counts, you can thank the jerks at she'll for reformulating w/o announcing such, and the QC gang for letting product through with whole chunks of whatever those chunks were in their final packaged product... I find that supremely disappointing, as I thought ibhad an oil for the life of the truck.
