Ok, I've put about 2,000 miles on this 2007 Accord I picked up used a few months ago. At first I was really getting nervous b/c the oil level kept going down. But, I removed and cleaned the PCV, and did an oil change with 5-20 M1 & Napa gold. It's held the level perfect, so I'm feeling a lot better now knowing that. This car has that oil % meter... and I've never had a car with one. Normally I do 5k OCI. So I'm tossing up the idea of either running Dino every 5k, or PP/M1 and follow the meter which says to change it around 20% left. Which comes out to aobut 8,000 mile OCI's. Opinions on either option? I'm down in FL, so extreme cold is not really an factor.
