I’m just telling you all, it was noticeable when I took the cap off and was pouring it. It smelled like a dirtier, less refined product. This was the Supertech Synthetic 0w20 marketed as 10k miles. I didn’t even know ST had an”advanced” 20k indicated synthetic. Oil might test out just fine, but I’m betting it would leave more deposits than a Mobil 1 or Valvoline Extended Protection. Any concrete tests to back that up? Nope. But next time you need an ultra cheap Dexos oil (in this case for a rental car) get you some ST regular synthetic and see if it doesn’t make you think its a lesser quality product.
You've been here more than a decade, and your takeaway after all that time is judging virgin oil on smell?
Look - it's time for some tough love ...
Lubricants have a job to do; that of reducing wear. This is achieved in many ways:
- reducing friction
- controlling contamination
- managing thermal loads
There are many, many industry tests to see how well a lube does these things. NONE of them involve a sniff test.
Further, the lube in question (any lube, for that matter) is just one consideration of several when it comes to controlling wear. These must also be considered:
- application (what equipment is it? engine? trans? gearbox? sliding door hinge?)
- specifics of the equipment as a known history (does the equipment have a known good or bad reputation well earned? Is is sensitive to anything?)
- environmental concerns (is it hot or cold where the equipment is operated, as a generality?)
- operational norms (short cycles? long cycles? intermittent cycles?)
- what is the OCI plan? (you can either underutilize or overuse a lube relative to its capabilities)
Simply put, don't judge a book by its smelly cover. For the unwashed masses, they follow the OE manuals and that will suffice well. But for the BITOG faithful, you ought to know better by now.
