Just to follow up on this thread, I got into it BIG time with service
manager. He claims that using 5W20 oil will void my warranty. So I took a
trip over there to show him my manual. Now the manual does also say that
10W30 oil is acceptable down to 0 degrees F, but that 5W20 or 5W30 is the
preferred oil viscosity for my 3.3L motor.
He still did not believe me and said that was a misprint. So in front of
me he called Hyundai directly. Well, he at some nice crow that afternoon.
He also was nice enough to apologize for his rudeness and sent a helper to
get 6 quarts of Synthetic 5W20 for my car. When the helper returned, they
changed my oil and filter again (while I watched).
So that was probably about $30 worth of oil, plus a retail $18 oil filter,
AND they threw in another free oil change for my troubles.
After learning that I had purchased 5 cars from this dealer, and referred
people that purchased another 4 cars, the service guy completely changed
his tune. Amazing what that will do.
Anyway, even after all this, I will be doing all of my own maintenance
myself from now on. My car will see the dealer only for warranty items and
