I have a 2005 nissan sentra with 70k miles that I bought from a grandma for $800 with 45k miles. I have put 25k miles on it in the last 5 months and according to the carfax the fluid was never changed. Is it risky to change oil on a car that is over 20 years old? The car runs flawlessly and shifts great.

I am feeling overwhelmed as I keep switching back and forth between what I want to do for my fiance and I's honeymoon in november of this year! I have 450k Amex points and 240k Chase points (150k pending once I hit my sub this month) so 390k. With the hyatt devaluation happening next week I am trying to get something figured out this week to lock in some rates, if I can not then it is what it is, or book a couple days now and the rest when I hit my sub. I will be flying out of Miami, and am stuck between a couple options for our honeymoon. Option 1 is an all inclusive resort somewhere south/tropical, I want it to be the absolute best and luxury I can get with my chase points (impressions/secrets) in that realm. Option 2 is PH Maldives. If I were to do that I would like to go all out and get a first class flight with my amex points, but I heard that is not possible with emirates anymore. Also going to the maldives sucks that it is not inclusive so does anyone know how much i should expect to pay cash for everything? Need some insight. Sorry if I am being confusing lol.
