background: my 64k mile 2013 passat has the old non turbo 2.5 liter, 5 cylinder, non turbo engine, which i like. just after going over its cpo warranty i had to spend $500 and three long trips to the dealer to fix a cel issue involving a cai valve. while there i wandered over to the sales floor and looked around. i was offered a lowball $5700 as trade in value, and combined with the dealership’s “easy, stress free, no haggle” actually high car sales prices, convinced me to keep my otherwise fine passat for awhile. i have religiously serviced my passat at this dealership. and i realize that a trade in will always be worth less than how the owner values it, especially an older passat. question: with this non turbo engine am i wedded to vw spec oil changes? im kinda p.o.’d at the dealership now with its high prices, and treatment like an off the street schmuck. in other words what are my options for high quality non vw spec oil grades and makes, and intervals, typically available outside of a vw dealership? i am not in a position to change oil myself. im not looking to cheap out but i am looking for other reasonable oil options at either 5k or the usual 10k intervals. caveat: this is the only vw dealership nearby, i have been to the next further one and it deserves its an unstelllar reputation. there are a couple of independent vw mechanics around but they look like junkyards. thanks in advance for your suggestions. and if there are no non vw options, so be it, please just let me know what you think.
