This shouldn't be a revelation for anyone here, we know that there's a specific way that these grades are supposed to be written, but we tend to be a bit loose with how that's executed on here, which is fine, casual company/discourse and all that.

Why do we see oil companies not following this?
For example, Redline appears to omit the dash per @Phishin's case pic in this thread:

And my cases and bottles of oil from @High Performance Lubricants all are setup the same way, SAE xW-xx:
Now, I know we've seen fudging of the grade format for grades that don't exist, like 0W5 for example, but, are there any consequences for not using the proper designation for those that do, or is this sloppiness just tolerated, despite the requirement?
