I have a 2007 Dodge Charger with 119k miles.. My engine randomly just seized and died while I was driving.. I towed the vehicle to dodge dealership for diagnostics, and they told me I've been poorly maintaining my oil because there is oil residue all over my oil filter, and it also clogged the screen which prevent passage for the oil which cause my engine to seized. But I have been routinely doing oil changes at this large franchise oil change company. I change my oil every 5k-8k and I do synthetic.. And before my engine seized my oil and oil filter was change about 3k miles prior. My question is can oil build up happen that fast within 3k of driving miles in my oil filter? Because my filter is full of gunk. Or is this poor workmanship?
And also, can oil build up happen if Oil changes were made routinely?
