5-20 oil

Who make 5-20 oil? I have a 2005 T&C with a 3.8 motor. We are coming up on
the time to change the oil. I saw the recommended oil is one I don't recall
having seen in the past. Would a 5-30 be bad?

All the major makers.

Is 5-20w now the recommended oil for the 3.3/3.8? My 1993 3.3 calls for
5-30.

If you live in a hot location 5W-30 might be a good choice. Mobil 1 comes in
both a 5W-20 and 5W-30 selection. That's what I use and I change at the
recommended extended change schedule of 7,500 miles or so.

I'm about to do the first oil change for my new 300C, should I do standard
or synthetic? I've used Mobil 1 for the past 30 years, does it make sense
to continue using it or are modern 5W-20 oils as good or better then Mobil
1?

They aren't as good as Mobil 1.

The UOAs for SL/SM IL-4 dino 5w-20s are just as good as for synth. The
owners manual says you can use synth, but you have to change it at the Sched
A or B intervals to maintain your warranty, so no real savings in terms of
fewer changes. Your call...

Somethin' in the air today that's causing confusion amongst "past",
"present" and "future"?

5w20 is being recommended by lots of automakers in their North
American-market vehicles for fuel economy certification reasons. The same
engines in the same cars often call for 5w30 in other markets. This does
not mean older vehicles should be switched to 5w20.

That is what I was trying to determine. From what I gather, 5w20 is now
being recommended for newer versions of the 3.3 and 3.8, depending on
the market. I will stay with 5w30 synthetic for my 1993 3.3.

Do new 3.3 and 3.8's have tighter clearances than their predecessors,
or is is the 5w20 recommended only for the purpose of improving fuel
economy?

No. Engine internal clearances haven't changed significantly in the last
four decades.

Correct.
