My car was built 6-01-12, so no XL-18 was added at the factory, could I request my dealer to add it under warranty? I baby my car till it warms up, but I do get the 1-2 synchro crunch at times.
No, BOSS MAN 13. Any service/repair you’d like for your dealer to perform (per your request) on your vehicle will be customer pay.
If you’re having a concern, you will need them to fully diagnose your vehicle. They will then advise of any repairs needed, and if the additive is necessary. I can also get this escalated for you if you’d like. PM me with your VIN, dealer, mileage, full name, and best daytime number.
