So my 2004 Jetta has an oil consumption problem with rings that were installed backwards. It's a well known problem of the MKIV Jetta - around 1 quart per 1000 miles during summer. I just did an oil change with 10w-40 weight and also mixed in some 5w-30. Let's call it 50/50 10W40 and 5W30.
Will the 5W-30 part of this blend be consumed at a faster rate than the 10W-40, or does it all just get mixed together. All valvoline. The 10W-40 is the maxlife syn blend. The 5w-30 is dino.
