Looking for some collective wisdom from any newer VW owners who have models that need the new vw508 specd oil. I am approaching 5000k in my 2019 GTI so I began tracking down supplies for an oil change and found out that the 19 GTIs are supposed to get the new vw508 spec oil in 0W-20 weight. No problem finding full synth 0W-20 oil but have only found three types that currently meet the vw508 spec: Castrol EDGE Professional LL IV FE 0W-20, mobil 1 esp x2 0w-20, and motul specific 508 00 509 00 0w20. Unfortunately NO retailer (even online) I have found sells any of them except the Motul which I can get from Europarts for $75 for 6 quarts + $17 shipping. For that price I can just go let the dealer do it. My question is has anybody purchased any of this liquid gold from anyone other than their dealer? Seems ridiculous not to be able to find oil for a car. Before a bunch of folks start suggesting just use something out of spec I have 5.5 years worth of warranty left and am not interested in getting into a battle with the dealer or VW if I need a repair because they don't like the oil I used. May not happen but rather avoid a potential headache. Any help with this is appreciated!!
