Just wanted to say thanks to everyone so far for the input. Its been very helpful and I appreciate it. I think what ill do is monitor the oil usage, if any, as well as the gas mileage and see how it goes. So far I do not notice any issues with a lack of power, so I do not believe it is plugged.
P.s., yep it made it to 572k on bulk oil changes at the dealer every 8-10k
