I have an 02 VW GTI 1.8T...here's my quandry... Ok, as the topic states, I think I may be...is this possible? This morning, while getting on the highway I kind of laid into the throttle in 3rd gear, looking behind my in my rearview I swear I saw blueish smoke up until about 5500 RPM when I shifted into 4th. Now, I pretty much baby my car, I never realy drive it hard at all...mabye on the highway once in a while I get on it, but for the most part I pamper it, I love my car too much. My oil history is: first change with conventional at 500 miles Penzoil 5W-30, then again with conventional Penzoil at 2500 5W-30, switched to synthetic at 5000 (valvoline synpower 5W-40), 8000 Mobil 1 0W-40, 12,000 LubroMoly Vollsynthese 5W-40, 18,000 Mobil 1 0W-40...which I'm still running at 23,700. Each time I used a new oil filter, either the stock filter or a Mobil 1, and I add maybe a 1/4 quart for every 5-6K. Anyone know what this could be, or had something experience? Is it blow-by, the turbo, breather valve/PCV...any ideas? This kind of worries me, this car is meticulously maintained and as I said I rarely beat on the car...just get on the throttle every once in a while. Shouldn't be happening with only 23,700 on the clock. Any help, info is appreciated. Thanks.
