Picking up a vehicle tommorow (personal driver, not LCO related) and it has 83k miles on it.

When is too late to switch to synthetic?

I don't think it is ever too late. If you have leaks it may get worse.

Correct, and oil consumption may rise if present.

I run it regardless unless the engine is burning it/leaking it...... then I tend to go with the cheap stuff if I am adding oil every month.

There are cars out there with 200k that run synthetic to answer your question. If there are no really noticable leaks then go for it.

I don't think 83K is too late, depending on how it was maintained before. Maybe start by switching to a synthetic blend? Just a thought.

I switched over my Toyota at 113k to Pennsoil Platinum full synthetic. No oil consumption yet, but it's just 100 miles. I granny drive it though too, I don't ride any of my vehicles hard. I take care of them and they take care of me.

every piece of equipment or truck etc that we have has amsoil run thru it, and if we buy it used we run BG products engine flush thru first, you would not believe how much crap that gets out. also run their compression restorer thru it next oil change, once again amazing results.

1k miles later, still no burn or leak.

Runs like a champ, still.

You really should not have any problems with any synthetic. Miles are probably less of an issue than age of the gaskets and seals. Pennzoil Platinum is a Group III synthetic, and I would think it would be less likely to cause problems even with older gaskets than a PAO synthetic would.
