[67 Convertible]

If you want the best for your car......no one will care as much about your car as you.
If you know how to turn a wrench, you can change the oil on your car yourself. The V6 is extremely easy, takes less than 30 minutes from start to finish. My car has not been at the dealer since delivery day 15 months ago.

I check my oil every couple of weeks, and change it every 5,000 miles, no matter what the DIC says. The V6 comes with dino from the factory. Maybe overkill, (I'm old school) but I changed my oil at 1,400 the first time with dino, and changed again at 3,000 with Mobil1. I have 16,000 miles on it now, and have changed the oil every 5,000 with Mobil1 and NAPA GOLD oil filter #7090. If you go by the DIC, you can get 8,000-11,000 between oil changes, depending on how you drive. (there are many different opinions on this)

As far as the other fluids, I check them occaisionally, but have not changed out any. I run 87 octane (there are many different opinions on this) and use no fuel booster, my car runs fine.
