Never anything other than 5w-20, and 5w-30, 5w-30 is the best choice, consider using an oil meant for car with more miles, I use valvoline high mileage and it finally stopped my oil burning. Using a heavy oil will cause high oil pressure, improper lubrication especially during warm up. 10w-30 is the high you should ever go and only if you can't find anything else.What oil viscosity should I use on a 99 accord w/ 200k miles?
at 200,000 miles you do not have to worry about warranty limitations. i will tell you this much, i own a honda with almost 250,000 miles on it and i run 1030 in mine with no problem at all.
High mileage oil. It's the right viscosity.
