I have used this in oil using engines in the past with some success:

Engine Restorer

You add it at every oil change. You could also try going to a higher viscosity oil such as 10W40 or 20W50 to slow the usage.

The 2009+ is a different engine, 2.5l vs 2.4l. I've no idea if the existing electronics would work with the newer engine. Even if it did the overall expense would likely exceed the value of the vehicle.

My first thought was to use thicker oil also. Since he's in NC, shouldn't be a temperature issue.

......Vehicle now has 175,000 miles and I'm putting 1 quart very 300-500 miles. It's not the end of the world. Recently I switched to full synthetic and Jiffy Lube is topping me off for free, so I'm getting my money's worth in synthetic oil, that's for sure (5 quarts in the first 2000 miles).....

Jiffy is topping you off with synthetic, for free, because it's burning it??
How did you get them to do that?

I'm in the same boat. Adding a quart every 6-700 miles meaning every other weekend. Someone said Toyota will lose customers. They lost this one in July. Bought a 2019 Tiguan. By by Toyota.

Glad VW has never had any "issues", right?
