I have the UPR as well... definitely makes fine-tuning easier! I do remove It completely during an oil change, however, because if you don't there's still some oil that won't drain. The Bronco is definitely a vehicle that you can't do a quick oil change on and trust whatever reading you initially get...I imagine that there's going to be a lot of overfilled Broncos if owners take them to quickie oil change places.It Sat for a couple hrs before I drained, removed the filler cap and oil filter. I let it drain for ~30 min. I filled with 6 qts per the manual. Ran it for a few min, took it around the block and checked again…at bottom hash. I let it sit for 20 min and checked the oil again, it was at the bottom of the hash still. I thought maybe it really does need 7…?!
The next day I was running errands, stopped by to get Another quart just in case. I got home let it sit 10 min, checked again and oil was still at the bottom of the hash, so I added .75 quart and it was at the top of the hash…
I had let it sit over night and checked per your post @broncorik (thanks man) and sure enough it’s above the top dot… I’ve never seen an engine take this long to drain and be able to properly check levels…
I had read through this thread and this one on the SSM. There has been so much back and forth on this subject, it’s ridiculous. It seems it’s still fine to fill to 7, but I decided to drain a bit so it was down to the top of the hash… Luckily I installed this UPR plug and it was pretty easy to drain just the right amount.
Given all this, there’s no way I’ll let anyone else change the oil…! So everyone just fill with 6qts and let it sit over night before you check levels again and add anything else…
