I'm not in any camp / group that would adhere to using VRP so early in the engine's age. But that's just me - my opinion. I suppose you could, just for preventative maintenance reasons and even use it for the lifetime of your ownership. But I wouldn't -not this early in engine life..
I replied, thinking you may continue with the Valvoline Advanced or jump into Valvoline EP. 4k would be a good OCI timetable on your 'now' mostly city-driven 1.6 TGDI. Many of us here at BITOG preach short OCIs with the Korean four cylinder TGDIs.
In any regard, be sure to keep that engine relatively clean while you own it and keep all oil change receipts, including date, brand viscosity / grade and mileage numbers on the receipts. In case of any engine troubles, dealerships may question you in regards to having them. You don't have to produce receipts, unless they prove you neglected or abused the engine.
They cannot deny you warranty work otherwise. Many folks driving these Korean-mades don't seem to realize that. They just cannot make you produce receipts out of the blue. They must identify to you a good reason, like proving to you that you should have been adhering to Severe Service Mileage recommendations. BTW..... I own a Kia and a Hyundai...... five and six years old and religiously did 3k OCIs until I recently fed these engines Amsoil and HPL.
This will be the first time I extend to an at-least 5k OCI with either. I changed to improve wear protection, not to seek extended OCIs. I have no bills at home and can easily afford to buy expensive oils that protect engine metallurgy better every 5k. But I won't discuss that opinion with anyone here inside your thread.
Here's hoping you have three nice Holidays coming right ahead of us. Cheers!
