Worst case 996 turbo overfill experience
Group,
Several months ago I purchased a 2001 996 turbo with 35,000 miles and love it!
This is my first post here but I have posted on Planet 9 related to my 2009 Boxster. When at the dealer to get my spare key programed, I talked with the mechanic who worked on my 996TT with the previous owner.
He walked me into the shop and showed me a 997TT engine completely torn down. The owner had the oil changed at a shop not familiar with the car, added 9 quarts, and only drained from one drain plug. They started the car and oil actually shot out of the exhaust. They quickly turned off the engine but it was too late
. The engine rebuild cost was 20K at the dealer (2 year warranty) and the inexperienced shop's insurance paid the bill.
It was a very enlightening experence for me and I now measure the oil that came out before adding oil when doing a change. Just my 0.02 cents.

I am really surprised that a shop could overlook the main tank! I can see overlooking the drains on the turbos, but not the OIL tank!

Probably not, if you are running 5-30 m1 try switching to Rotella T6 or m1 TDT 5-40 for a couple of oil changes. Mine stopped smoking on startup cold or hot since

I also use 0W40 Mobil 1
Several weeks ago I changed the oil in the 996TT measuring the amount of oil coming out and initially putting in 1 quart less. I then checked the oil gage and slowly added oil in 1/3 quart increments to show full but not over full on the bar gage.
My 2009 Boxster was another story. I added one quart less than spec and attempted to slowly fill to top off per the gage reading. I ended up being one bar over full. I knew I was not over 1/4 to 1/3 quart over full so I checked online and the majority of people said it was not an issue. I did notice more periodic exhaust smoke during start up. After a few partial day trips the gage finally ready "full" which was a relief.
