My daughter has a 2009 Honda accord with 85k miles on it. It goes through 3 qts of oil between oil changes. We submitted a claim even tho the warranty was out by one week but not out on mileage. They told me to take it to a honda dealer ( Ray Price ) to do an oil consumption test. Which consist of a oil change (i paid for) then bring it back in around 1000 miles , they check level then report to Honda USA. Here's the problem, i took it back it lost 3/4 qt by the calibrated eye of the mechanic looking at the dip stick , he didn't drain and measure. Also they didn't use the same weight oil as in the owners manual. The real misconception here is that it loses at the same rate. It doesn't between the first 1k miles and the 2nd 1000 miles it loses faster !!! and so on. some time between oil changes I'll put in 4 qts.!! Also this is highway miles, if she has around town miles she'll use 5 or 6.
Banging my head in Bangor what can i do?
