Just inherited a 2012 civic 1.8 from my aunt, and she always had it serviced at the dealer promptly when the maintenance minder came on. It has 92,xxx miles, I switched to Mobil1 and a Honda filter and ive been burning about a 1/2 quart every 700 miles since the oil change, about 3400k since last oil change. No leaks and it runs beautifully. I didn't see any mention of low oil during any previous dealer oil changes which has me wondering if M1 is causing the burning(im sure they may not even check)? Should i try switching back to Honda's oil? Very strange, not sure what the next step is.
