You dont want to learn... All you want to do is prove your dick is bigger then mine.
The way, in simpleton speak, of how a 5-30 can be thicker then a 10-30 is this..
The window for SAE to call a 5-30 is huge.... In fact, the top end of SAE spec for 5-30 overlaps the SAE spec for 10-30...Depending on brand.
Lets say brand X 5-30 is at the Top end of thickness for a 5-30
And Brand Y 10-30 is at the bottom of the spec for 10-30..
The 5-30 WILL be thicker.
