Why worry? According to many people here the oil can't void the warranty, the car maker would have to prove the oil is at fault if the engine takes a dump and dies.
Since synlube is such a fantastic oil, and Kirk pours into his new vehicles with no worry, and runs extended drains in new cars, why should you worry? Go for it if you have that much faith in the product. A Shipmate pal of mine dropped the Factory Fill in his new F250 and went with RL 5W20, a non certified oil w/o any fear. Oh yea RL is a real company with an actual street location.
AD, a touch of sarcasm. Easy there...
Well, bully for you friend. That's his truck and he's welcome to do what he wants, just like me. Nope, makes no sense to not change the oil for 10, 20, 30, 40, 50 thousand miles. The numbers get real big when transforming to metric. Believe me, the Ford crowd up here are not into very long OCIs. If something with wrong with the motor or driveline, they would laugh me out of the service department if I go in there looking for warranty and can't prove that the oil had been changed every 5 000 kms. Not worth the risk. I can wait. It's unlikely that I'll have a warranty issue with the engine. I've not has one in more than 20 years. Can't remember having an issue ever with the engine or tranny. Mostly recalls over the years.
