Sure, you're using an oil that's thicker at ambient temperatures (5W vs the OEM 0W), so your oil pressure will be higher when the oil's cold. Your oil pressure should be similar when the oil's fully warmed-up, though (both oils are 40-weight). The 0W-40 Mobil1 shears a bit through use, too, so the old Mobil1 was probably thinner when hot than your new Motul oil.Question I have is I notice my oil pressure goes up faster now when I hit the accelerator. Almost to max. Then settles down to 20-22 again. Is this normal? I used Motul 5w-40. I live in Las Vegas so I like to go a step up in viscosity.
Now that wasn't the slightest bit disparaging.....Its going to be a bit slow in seeing DIY'ers this time around since unlike the Cayman/Boxster as we knew it attracted more of that crowd. 718 attracts more of the take it to the dealer crowd - not that there's anything wrong with that.
Thanks and interesting on the 6.75 qts. The manual states around 5.7 liters I believe.Hi Fellow 718 Cayman S Fans, I'm a DIY guy and just successfully changed the oil and filter in my 2018 Cayman S w/PDK&PDL. I have to say its the most difficult oil change of any car I've ever done. I've never had an oil filter that couldn't be removed unless other pieces of the car (other than an undertray) were removed. I watched both of the helpful videos I could find and the one that required the removal of the headlight level sensing mount was the one that I needed. I actually never removed that level sensing potentiometer - I only disconnected the bottom ball joint bolt to drop the connecting arm down. I still couldn't remove the filter housing - there simply wasn't enough room to get it out. That headlight sensor thing, the position of the bolts on the driveshaft, and some cabling in the space in that area all conspired to really restrict the removal of the filter housing/element assembly as a whole. It was like it was 'in a cave' and the filter housing itself was bigger than the 'entrance to the cave'!!!!! There was much labor involved just to get access to the filter and not much room with which to work.
There is plenty of room to rotate the filter housing in the space above where it is mounted once it is unscrewed and I was able to point the open end towards me (ie towards the "entrance to the cave") to remove the filter element and clean the inside of the filter housing while the filter housing is still 'trapped in the cave entrance". There is also room to move the filter housing up in the space above and effectively clean the mounting point and wipe the area clean. Removing the o-ring on the filter housing was also not easy with the filter housing trapped, but it was doable. Once the new filter element is installed and the two o-rings are lubricated, it relatively easy to screw the assembly back into place by hand.
I drained 6.75 quarts of oil and replaced it with 6.5 and after a drive to warm up to oil and coolant operating temperatures, the level was green and indicated a complete fill - I'll monitor this over the next few day.
If this car wasn't such a TOTAL BLAST!!! to drive - this oil filter access nonsense would really give me pause in ownership. I look forward to other DIY-ers posting better tips on how to do this...Be safe out there....
Many thanks for your account and insights. I agree - even with a manual 718, this was the most difficult oil change I've ever done.Hi Fellow 718 Cayman S Fans, I'm a DIY guy and just successfully changed the oil and filter in my 2018 Cayman S w/PDK&PDL.

I have heard that the iCarsoft POR-II can do this on the 718 models. It is available on Amazon, so you could return it if it does not work for you. There is one review that says "I also tried it on my buddies 718 Cayman to reset his major maintance warning and it worked like a charm. The unit plugged into his OBD port much easier than mine". This device was also mentioned here on rennlist.I can't find anywhere how to tell the computer you've changed the oil. anyone?
