Did the oilchange on my lawn mower today, took off an STP S3512 and it had synthetic 5W30 in there.
there were noticable gold/metallic particles in the engine
I'm not quite ready to be alarmed, even though it's 2-3 years old I would estimate that it doesn't even have 100 hours on it.
However, I thought I would pickup something better to the effect of a Napa gold 1348, but, looking up the beta ratios for the wix exchange;
Beta Ratio: 2/20=21/37
you can see that it's effenciency is pretty horrible, and that's for an $8 filter mind you.

questions;
I'm planning on using M1 Ep 5W30 for all my combustion engine service needs(I threw it in there for the OCI today), makes things simple, and I believe I used something similar last time. I would think that it would be very much overkill for a 600cc 1.5quart sump motor-- is that about right(being overkill) or could it be causing some extra wear? Or is the metallic oil a simple fact of the poor filter filtration & capcity as well as the fact that it's lawn mower engine.
Thanks.
