I want to thank everyone for their input and help.
Since my wife's Yaris won't be seeing 25000 miles for nearly 3 years, maybe it is best for me to focus on the Accord at this time.
The owners manual for the Accord recommends "Genuine Honda Motor Oil" or "Premium-grade 0W-20 detergent oil with an API Certification Seal on the container". The manual also says "You may use synthetic motor oil if it is labeled with the API Certification Seal and is the specified viscosity grade".
As for changing the oil, the manual wants me to change oil when the "Maintenance Minder" tells me to, or per the fine print, "If a message SERVICE does not appear more than 12 months after the display is reset, change the engine oil every year".
Does the "Maintenance Minder" go off when I reach a certain amount of miles or engine hours or does the engine have some sort of sensor that monitors the condition of the oil?
In the past I have averaged anywhere from 10,000 to 15,000 miles a year on my car and if I would only need to change the oil once a year, well that would be a bonus for me.
Will the "Maintenance Minder" give me credit for using synthetic oil or will it want me to change it at the same intervals as dino oil?
When I bought the Honda, the dealer was really pushing a pre-payed oil change package that included a synthetic blend oil (I didn't buy it). Would the "Genuine Honda Motor Oil" or their "Synthetic Blend" be any better, worse or just the same as any other of the shelf API motor oil that I can buy?
If the Honda oil will give me better protection and quieter engine operation than other oils, then I'll watch for a deal and pick up a few cases when I see a good deal. On the other hand, if another oil that will only need to be changed every 12 months will also give me better protection and quiet engine operation, well then that is the way I would prefer to go.
Another thing to keep in mind. I have seen some discussion online questioning the new Honda "Direct Injection" and some wonder if it will be raising the oil contamination level with fuel like some other D.I. engines have.
If it turns out that my new D.I. engine does indeed add higher levels of fuel contamination to the oil, will any certain type of oil give me better protection than another or will I just be faced with more oil changes a year?
If there is an oil and a filter that will give me better protection and quieter (I hate cold start engine noise) engine operation that will resist fuel contamination (should this turn out to be a problem) and will only need to be change once a year, what combination would be best for me?
Thanks again
