This is only required if using 100LL more than 30% of the time.

If someone is using unleaded fuel nearly 100%, then it is not necessary.

I installed a Curtis-style quick drain on my RV-12. No fit problems and it is simple to attach a short drain hose and open the drain valve.

Safe air has a fitting that lowers the valve to allow it to open with the domed tray. I have it installed in my Rans S19. Makes it easier to drain the oil and even keeps it neater if you are going to remove the tank for cleaning.

Some aircraft oil tank installs leave no option to access the oil tank drain plug so they do remove the tank to dump the oil which is perfectly acceptable.

There is no access issues at all with the oil tank on the RV-12 so not relevant here in this forum.

The funnel idea I mentioned above I got from one of your RV12 users, works well and seems to keep everything clean. I forgot who told me about that idea.

I guess they do their oil changes out in the open with the wind blowing?

I have never had any problem with oil getting on anything while draining the RV-12 oil tank, and would prefer to not have one more tool to clean up afterwards.....

Lockwood sells the fitting you need if you have the newer tank. It works great.

I do my oil changes in the hangar, so no wind. I do see some oil draining on the firewall flange. I just put in the Curtis drain valve, and I am looking forward to a cleaner drain next time.
