I just bought a used 2013 Dodge Grand Caravan and don't have the user's manual for it, and couldn't find the information looking through the online version of the manual.

I have a 2010 Jetta that, when I got it (also used) was pleasantly surprised to find that synthetic oil is recommended that this increased the time between oil changes significantly. I couldn't find what kind of oil (conventional vs. synthetic) is recommended for the Grand Caravan and also whether using synthetic oil would increase time/mileage between oil changes relative to conventional.


Using synthetic oil in and of itself would not increase change intervals. There are products on the market which would allow you to do this, though, such as Mobil 1 Annual Protection. According to the product literature, it's good for either 1 year or 20k miles. I believe Amsoil has something similar (or their suggestion is for running a longer change interval). (Note: I have no affiliation with these products.) Other than products like these, you should change the oil at the manufacturer's suggested change interval. Synthetic, while being superior to conventional oil in almost every way, is not a magic bullet.
