Motul 300V 5W40 racing oil

JB911

I've been doing my oil changes on my 997.2 GT3 for almost 10 years, and after draining for a reasonable amount of time, replacing filter etc, and then adding 9.5 quarts is always just about right. The Service manual info I posted above offers more info. If you wait hours with the drain plugs open, you can get more oil out, but I think that's just unnecessary.

Caution-some people and even shops(happened to a friend's turbo in a "reputable" shop):
Check the oil the correct way-fully warmed engine, level surface horizontally. Some people panic with a semi warm engine and the indicator shows what appears to be a low level, a bit over half way, and then add a quart. Once the engine is fully warm, the indicator confirms you end up with too much oil which is very dangerous-
So filling between 9 and 9.5 quarts is it-
