Yes, you can with no problem. Virtualy all oils, synthetic & conventional, are interchangeable.
A used Honda Odyssey will probably run you about ten thousand dollars, depending on just how used it is. If it has under 50,000 miles, it should be about 10K.
Light weight vegetable oil or olive oil is best used on an odyssey. *edit* Randomize: (alternatively; if you aren't intending your vehicle for the preparation of food for human consumption, Castrol 5w-20 or 5w-30 synthetic will be sufficient also...)
Honda Odyssey's cost around $25,000 to $30,000 in the United States. Depending upon your options and upgrades, the price can increase greatly. Honda Odyssey's can also be bought used. In which case you could pay much less.
Use 10w30 Synthetic.
Yes
5w 20
There are many different sources to find a used car such as a Honda odyssey. Newspaper ads, websites and even tv commercials can give you insight on the best location to find what you are looking for.
You can determine the value of a used Honda Odyssey by looking it up in the Kelly Blue Book. You input data about the car, such as the mileage and area where the car is, and it provides an accurate estimate of the worth of the car.
