Welcome to Moto Guzzi and the WildGuzzi forum. I had that exact bike many years ago. Those tube type wheels are an easy changeover to the EV or early Bassa tubeless wheels.
The tires are Metzeler tubeless both front and rear. They're definitely old (fronts 09 rears 08) despite looking new.

I spent 10 years in crankcase oil additive development & we always 'shook the can' before engine testing/field testing/regular use - with lots of 'competing' additive chemistries, & especially in synthetic base oil, the additives are either trying to stay in the oil, leave the oil, or coat the inside of the oil container ! A short shake & the dispersant additive will hold it in the oil long enough to tip it in the engine.
Do you believe that advice applies to old oil that has begun to oxidize, which in turn affects some of the additives? With your experience, I imagine you’re aware that oxidation is a molecular-level change, meaning the molecules are losing some electrons. Along with the degradation of the anti-foam properties, it doesn’t seem to me like shaking will fix aging issues.

Upon further study of the pictures I have questions about this machine. I am wondering why a bike with 8000 miles has been repainted, seat changed out, mufflers replaced and tail light assembly removed and replaced with cheapo crap?
50 Years is a LONG time to keep something unmodified. I wouldn't assume foul play or problems. I have new Paint, run a Bassa Exhaust, changed out the seat and rear fender. I don't even know if my tail light is the right one. It came with a King/Queen Monstrosity and a second custom Bench seat. The Original seat/rear cowl and wings were long gone, before the guy I bought it from. I bought one of the Original Guzzi Barn Door windscreens, but take it off in warmer weather.

Seems to me a crankshaft turning at 6000 rpm will mix that oil up is short order. Having run my Norton for 25,000 miles with broken piston bits sloshing around in the crankcase and no oil filter I think I have a better idea how much damage old oil with no piston bits and an oil filter will cause. Not much. Go fast, take chances.

The old “just shake it up” advice has always seemed somewhat ridiculous to me. I’m not a highly intelligent man, and I don’t have expert training in the matter, but I do know that the human arm, including the muscles, tendons, ligaments, and energy stamina involved, will not suffice proper mixture of additives back into the oil. We’re talking molecular bonding—maybe dipole-dipole, ionic, London dispersion?—and that type of mixing cannot be achieved just by the human body. Like, much harder than trying to make a good homemade mayonnaise with only a spoon. I brought up Lake Speed, Jr. He’s actually an expert. Easy access to laboratory testing. An academic degree in the very matter. In fact, he even posted a video as a follow up to the one that I shared above in which he addresses the topic of “just shake it up’. Here’s the link: https://youtu.be/QeNLVUdoBU0?is=5o7CGqwcqsrFaJq_When tests/experiments are made with proper control and parameters, I’ll follow that over popular ‘wisdom’ any day. Science wins. My grandfather used to dump his old engine oil out on the ground, despite the fact we had a lovely creek just 40 yards downhill from our barn. He always told me it wouldn’t do any harm…wisdom, right? Or maybe just ignorance. I don’t want my engine to blow, and the test results in Lake’s videos scare me enough. Better safe than sorry, right?

Great info here for all to discern. Luckily mine passed the tests,. clear amber - oxygen foaming test being old Liqui Moly but I have yet to cut the carton up - that will have to wait for a bit. I called the Company and got thru rather quickly and told under no circumstances to use oil older than 5 years from Manu date. Mine is 17 years old I was told.
I knew it! Big oil is be inchoots with big tire and their 5-year expiration date.

Just saw this online. Caption read: Jinzhong, China. Autumn foliage surrounds the Taihang No 1 tourist highway in Taihang Longquan. The route, which passes through six cities in northern China, extends to more than 5,000km (3,000 miles) Looks like almost no one's on it.
