Consumer Reports: As MPG rises cars using more motor oil between oil changesSubmitted by meekandmild on Mon, 07/01/2013 - 12:52
Even Japanese cars known for their reliability have lately been burning oil. When I took our 2012 Subaru Impreza to Boston for a weekend, it dropped down a quart on my way back, prompting a late-night search for more 0W-20 weight oil.
Auto engineers have told me they see no correlation between today's lightweight "0W-" motor oils, designed to reduce friction and save gas, and excessive oil consumption. But in our admittedly anecdotal experience, both the prevalence of such lightweight oils and the propensity of more engines to consume oil seem to be moving in tandem. And our test cars that have had this problem have all used such lightweight synthetic oils.
Has anybody else seen a correlation? Had a problem with a relatively new car consuming excessive amounts of oil? Do you think "a quart every 1,200 miles" is normal and/or acceptable for a modern car?
