Not really. The Legend is up to around 700 miles since adding EC30 and the lifter tick still hasn't been eliminated, but it ticks for significantly less time than it used to. I'm planning on pulling the front valve cover this weekend just to see how a reduction in lifter tick translates to visible valvetrain cleaning.
I had to order a second quart of EC30 for the Legend because I have added about 2.5-3 quarts of oil since adding the first quart of EC30 and need to maintain approximately the recommended ratio.
My friend with the CRV is about 500 miles into the EC30 experiment and the it has used about half a quart, so the rate of consumption hasn't changed yet.
