Mine don't use a drop... unless I go over 70mph for a bit... then it just churns so hard, it throws some out... (I don't think it's burning it,... it's just violent seas in that little box)...
Synth oil is so good... it can sneak past places that dino wouldn't...
It's almost a good penetrating oil...
... and again,.. I'm going to agree with WD... a cone filter is out in the open... you may hear whistles of suck that would be masked in a airbox...
It's like you riding a bike with no helmet and yer' mouth wide open...
You gonna' make some weird noises...
...
I know some guys that did oil changes,.. but forgot the oil part, or the plug part... and their engines gave up in 50 to a few 100 miles...
... or they didn't...
If it does,.. just get a another low mile engine... and put it in...
Trying to fix what got toasted is just a waste of time...
What you can't see damaged, is just damage that hasn't shown symptoms yet...
Fingers crossed...
