Makes all the sense in the world, I knew there was more to it, just couldn't remember all the talking points when I replied yesterday, thanks for the additional info.O875 wrote: Sat May 30, 2026 11:29 pm Part of the changing the oil before it's stored idea is that if you've used up the anti-corrosion additives then leaving the old oil on the bearings in that state isn't helping the engine. Better to store the engine with fresh additives, including the anti-corrosion ones.
Been enjoying this discussion. I'm trying to work out the best option at the moment, for a climate that sometimes exceeds 35℃. I'll probably go up to the over 35℃ range with the oil, just in case.
From my simplistic "regular guy" point of view, oil changes are relatively inexpensive and DIY friendly in most cases, so anything we can do to stack the deck in favor of minimizing long term issues is worth exploring.
Of course, when it comes to the 997, I pay "the guy" to do the oil change simply because it is a little bit of a PITA to get right. As much as people talk about the 997 being the "last mostly analog 911" the one thing they should have left "analog" was a damn dipstick, it doesn't have one. It relies on a digital readout on oil level and it takes a long time to get it to actually read the level correctly as the oil has to drain all the way down to the pan and everyone fills to just under the fill line for a million reasons I cannot recall but overfilling the slightest bit is like touching the third rail.......so I'll pay the guy with the 911 and DIY for the 924S........again, first world problems.
