I have a 1997 2.5L Boxster and I have run through several forums, browsed my owners manual, technical manuals and read many different capacities for the engine oil with filter change. My owners manual states Approximately 8.7 quarts. At exactly 8 quarts I am showing at the low side of the dipstick and the display shows low. At 9 quarts I am showing at the top side of the dipstick and the display still shows low. Is there a consensus on how much to add to the 2.5L version? I have read as low as 8 and high as 10.
I do not know whether to trust the dipstick due to its poor design or should I trust the display level. Just want some input from you guys who have been around awhile ...
