New oil for the GT engines

Right - but 5W-40 was previously approved for C40 applications… then the 5-weight suddenly fell off the approval list from Porsche. Wondering if Mobil paid Porsche for that too… buying oil from the dealer is a total f*ckjob.

That's hilarious. I remember specs for the same-marked oil from different years were slightly different but here it is all the same year with different datasheets. I think the only reasonable option here is to stop worrying and just do exactly what the manual says.

Shares a motor with the 991 Speedster (might be tuned for 10hp more or something, 520PS like the 991.2 RS but newer motor with ITB's and OPF housings). Just the end of RoW-spec 991 GT3 RS production - last revision.

I do not believe 991.2 GT3 RS has the 6 individual throttle bodies and updated Speedster engine. Please provide your source — I’m pretty sure Speedster was the only 991 that got the updated engine, as it happened at the very end of 991.

Here's one thread, but there are many others if you search "991.3" on 991 GT3 Board here:
