Unsure on wear.. haven't heard any "horrible" noises yet. lol
You should contact Blackstone Labs
for an oil analysis kit. Draw a sample on your next oil change to see what the wear is like. It'll cost you about $22.50 plus some postage to send the sample to them. They will email and snail mail the results to you.
