Here's the short version...
2002 VW Passat 1.8t, 57k miles. 5-6k OCIs. Only oils ever used MI 0w40 or U.S. Syntec 5w40.
Saw sludge deposits on oil filler cap. Asked dealership to check it out. VW has 8 yr./80k mi. sludge warranty, right?
Tech. wrote "Inspection found some build up, if customer has been using synthetic oil throughout the life of the vehicle the sludge issue may take awhile to cause oil pump failure."
This OCI, I brought in my own 0w30 GC. I want to use an oil that not only meets VW 502.00 spec, but also has highest deposit-cleaning ability. Is GC the best choice? I will ask about using Auto-RX in a separate thread-I just want to know now what oil is best to use straight.
Thanks...
