Ok good stuff. So I am just a basic DIY home gargae oil change guy.
Now some dummy questions? What is MMO?
Is the Mobile 1 High Mileage a good one to use to help some?
I called the guy who got the car for 2 weeks then Sold it to me. He now just a few mins ago tells me he did a Flush with 1/2 can of Motor Medic Motor Flush then changed the oil and filter just 300 miles ago. That worrys me. Said he did because he took it to a Nissan Dealer and they told him it was heavyly sludged. I'm take you guy's advise here. I thought the engine would be ok myself too.
