At 131,078 miles, 500 miles after my first Mobil 1 “advanced full synthetic,” 5W-20 oil change, along with a Motorcraft FL820S oil filter, my oil dipstick is nearing the add mark 😢. Should I go back to 5W30 conventional?

It's not uncommon for an engine to consume a little oil right after a change to a different grade and/or formulation. Keep driving and checking the level periodically and I'll bet the consumption slows or stops.

Update: after driving it from work 6 miles this morning and letting it sit in the leveled garage floor for 40 minutes to eat my breakfast, I rechecked the oil level and its full 🧐. Was I supposed to check it after the engine is warmed up or what? Per Scotty Kilmer, its best to check it cold and parked on level surface which I did this morning before going to work which appeared to be low 😱. When I refilled it new during my first Mobil 1 AFS oil change, I put in 5 full quarts and checked it a few minutes after filling. Didn’t start the engine and let it run for a minute, just filled it and check. To make sure I was safe, I checked the owners manual for the correct capacity before refilling.

Scotty Kilmer is good for a laugh a diversion but I wouldn't consider anything he says as tech.

My 2000 GM required 5.5 quarts of oil to be at the top of the crosshatched section ("full"). Once I got to 250,000 miles or so I would do 5.5 quarts because in 5000 miles it would use about a quart, but I wouldn't have to add.

Hot or cold shouldn't matter, what matters is that it sits for 15-20 minutes first. I suppose if it was ran but not brought up to operating temp then shut off that cold oil might not all return to the pan in that amount of time, but if the car sat for quite awhile cold shouldn't be an issue.

I never really saw any difference in consumption between 5w20 or 5w30 but I did go to 5w30 towards the end. If the car sat for a few days or more it would smoke a little at start up. Nothing real bad and 1 quart consumption in 5000 miles at that point wasn't a deal breaker for me.

I try to check the oil level with the vehicle parked on level ground … and always with the engine OFF. I just eyeball "level", I don't care if the engine is hot after a drive or cold from being parked all night where it sits. Hot oil will find it's way to the sump in a hurry in a hot engine, cold oil has had all night to find the sump. I pull the stick, I wipe it clean, I re-insert the stick all the way, then I pull it again and read it.

Next oil change I'd probably use 5w30 synthetic.

I never used full synthetic on any of my vehicles till recently. Been strictly ford semi-synthetic 5w20 oil in my 04 marquis,03 marauder and 08 F-150 5.4 3v. I switched to 5w30 ford full synthetic in the F-150 and after 4000kms it was halfway down the dipstick. Never used oil before. It also developed the dreaded startup rattle shortly after switching to synthetic. Could be coincidence cause the 5.4 3v is known for problems but I switched to 5w30 semi-synthetic and no tensioner rattle since. I do mostly short trips and change oil frequently so I don’t see any advantage using synthetic in my case.

I check with oil with engine cold and on level ground. I prefer to check it after it has been parked for a while like overnight in the garage. Out of all the panthers I've owned, I have never had one run even a little low on oil. I'm also in CA with mild weather so I only use 5W-30 full or semi synthetic depending on whats on sale at Wal Mart. With San Diego weather, 5W-30 should be just fine.

On your 98, conventional should be fine but just require more frequent changing compared to synthetic. Main thing is just to change your oil at a regular interval.

Another thing to note is with these dip sticks, I notice that one side always runs "high" on the level so I check both sides of the stick to see which is the full correct one.

Did you change the filter with the oil? If so, that's where that partial quart went. After a change, you should always run the engine at least enough to fill the filter, then check and top off...

I always do when I can...when the vehicle isn't retarded like ours are with the oil filter mounted horizontally.

I also fill the filter. In our case, I fill the filter all the way, then swish it around a bit so the oil soaks through the filter media and into the outer part. The ADBV holds most of the oil in while I tilt the filter to screw it on. Probably OCD, I know, but I'm retired and have nothing better to do. gene

Many will disagree but I've seen this again and again: if it's been using conventional or semi-synthetic for a long period, don't bother switching to synthetic. If it's been on synthetic since new, stick with it.

Conventional and synthetic oil have different philosophies on how to protect an engine. For conventional it's just varnish up like a mofo and that'll keep everything tight. Synthetic keeps it clean and lubricated. Once you switch to synthetic from a long-time conventional engine, the synthetic starts eating away the conventional varnish and problems ensue.
