My wife and I went to Tennessee over the weekend and I had to get back to Lexington before 7:00 pm last night for a meeting ,so I had to haul ass after getting stuck in road construction.
I averaged around 80 mph on I-40 and I-75. At times, I was driving over 90 and just under 100 mph. There's quite a few large mountains to get through 75 N through Tennessee near the Kentucky border. Almost straight up hills at times.
Here's what happened........once in Kentucky, I noticed in the rear view mirror that when I punched the accelerator, a small cloud of smoke seemed to come from the exhaust. The engine never overheated. I didn't smell anything "hot", or "sweet" like it was coolant; I didn't have smoke coming from under the hood once I stopped; I didn't notice the small burst of smoke when not pushing down to quickly accelerate past someone. The smoke was gray/white. It definitely was not under performing or running rough, nor did it make any odd pings/noises.
Total drive time of driving that fast, and up mountains, was around 3 hours. The car was driven pretty hard. Once we got home, the car wasn't hot at all. I changed quickly and got to my meeting and had no issues with the vehicle and didn't notice the smoke clouds again even though I purposely tried to recreate it.
Was this smoke simply from carbon deposits being burnt off while driving that hard?
