I was waiting for You Travis and and You hit it right on the nail I did started using wvo and amsoil at about the same time. I do leave it idling for very long periods most of the time. I just don't feel like turn it ON and drive so I let it warm up for 30 hour some times (bad habit) but even with no knowledge of this I started to shorten the idle time a while back.
Well I'll need more oil and filters, will run it for 3k and see what difference it makes.
BTW some times when I turn it to oil, it will not be at the recommended 150f for a long time, maybe that could affect it since the fuel wont burn completely.
Thank you all guys
, I'll change the oil and bad habits and post back on this one.
