Yeah, I usually take my car to my nearest Dodge dealership for my oil changes because it's almost the same price if I did it myself with oil and a filter and it's much quicker. I'm pretty sure they're using the right velocity of oil at least it's what it shows on the sticker they put on my windshield, they don't ask what oil type I want but I just figured being a dealership they'd know what to do, someone said I should be using full synthetic oil because of the age and mileage but I'm not sure.
As for the o2's and catalytic converters the person that owned it before me messed with the catalytic converters and the whole exhaust system and messed up one of the o2 sensors post cat on the driver side, the catalytic converters are also messed with pretty bad and welding was very bad, I think it has a slight exhaust leak but I've already had it looked at by a performance car expert and he said I'm definitely losing some power but until I can afford to deal with it I should be fine, I'm planning on having the entire exhaust system redone soon, from new headers to exhaust tips.
As for the knock sensor the code came up on the dash like in the video, but when I took it to a shop they said they didn't see the code on their scanner, the engine runs and drives and idles very smooth and there's only the roar of the engine, not really any other noise, except when it's cold it'll vibrate slightly but it goes away, my acceleration is funny at times and I just had the transmission rebuilt recently so I'm not sure if it's from one of the trouble codes or something else.
I appreciate all your help guys, let me know what you think! Thanks!
