Changed my 2005 Hyundai Accent automatic transmission fluid for the second time at 70k(In last changed it 5yrs and roughly 45k miles ago), I didn't realize the used fluid was so much darker when I checked it on the dipstick.
Did I do good by getting this old, dark fluid out of there?
i know pretty much nothing about cars (+ this is my first car) but i’ve had this engine code on for so long, I wasn’t able to deal with it due to money and personal issues
today i decided i’d finally do something about it, i got an oil change with valvoline maxlife synthetic blend (the one that helps w oil burning & leaks)
i heard that that may help the engine code, and my friend has a reader that can clear it so we cleared the code after the oil change, and it came back on quite quickly, so we drove back home and cleared it again, we drove about .5 mile down the road, and then turned back around, and it turned back on after about .75 a mile, and then we cleared it again, and left it idling for a bit trying to let the oil run
it turned back on some point during the idling
it isn’t making any odd noises and there’s no active concerning issues, but i read my other option is the timing belt but i also read that is a very expensive repair and frequently has loud noise / stalling / rattling which none i have
is there anyway to determine exactly what’s causing this? or should it be good now that the oil change is done?
it had very low & dark oil prior, and the light was on for about 5-7 months, i’m not sure exactly how long because i had a gas cap light for a while and assumed it was that, only issue i have that could be related to this is slow acceleration
