Let me preface this with the statement that there are no oil leaks. The car is parked in a garage with a painted garage floor 23.5 hours every day, and there isn't a drop of oil on the floor. A dealer inspection also indicated this was oil consumption and not an oil leak.
My wife has a 2005 (new body style) Jetta with the 2.5L I5 engine. She has a little over 20K miles at this point. We forgot her 3rd (15K miles) oil change by 4K miles and when we took it in, oil wasn't registering on the dipstick and she was 4 quarts low according to the dealer. I was quite surprised to see oil consumption like that for full synthetic oil and a fairly new car. My 100K+ truck may consume 1/2 quart over 10K miles. The dealer we took it to, MAG - Midwestern Auto Group, seemed to imply we had possibly destroyed the engine and that if it continued to have problems, VW would not honor the warranty. Needless to say they did not get on our good side by those types of comments. So they changed the oil and we drove off with the understanding that we would bring it back after 1000 or so miles for a checkup on oil consumption.
When my wife took it back this week, they said she had lost 1/2 quart of oil over her 1000 miles. The dealer then said this was NORMAL! They said 1 quart every 2K miles is what they expect to see in oil consumption. Maybe I'm missing something, but I expect roughly no oil consumption after 1000 miles on a car with 20K miles. Additionally, synthetic oil manufactures are now recommending 10K and 15K mile oil changes unlike VW's 5K mile recommendation.
So I wanted to get the r.a.m.vw.w group's thought on if this is normal or not. Should it consumer 1 quart every 2K miles? Did going over 4K miles on an oil change destroy the engine?
