So it says on the can of seafoam that you can add some (a little, 1 ounce / quart) to the crankcase prior to an oil change to help clean out some of the sludge. I'm planning on changing the oil this week-end at the latest, it's time, so I poured a little under an ounce in there this afternoon (I think it's under the recommended dose since there is about 1.6 qt of oil I believe), knowing that I should use my bike at most 4 times this week to go to work. That's about 80 miles. Is that too much running the engine with slightly more fluid oil than normal? Should I change the oil before that? Or is it OK? I haven't done the math but it doesn't seem like it's a huge % of the total volume so viscosity should not change that much, but I'm not 100% sure... actually I just did, 1.6 quart ~ 51 ounces. So I guess there's 2% of seafoam in there...
