92 5.0 supercharged mustang oil choice

[Vegasguy]

Buddy has a stock motor supercharged 5.0 mustang and wants to know what oil to run in it. It's driven sometimes in the summer during summer heat here in Vegas and is driven hard when used. He just got it and has no idea what previous owner used. Any suggestions?

You'll get some great replies, that vehicle is a favorite of many here.

Mobil 1 10w40 high mileage

We talking stock right down to the E7TE heads and factory intake? Any idea of how much boost he's running?

I typically recommend a 0W-40 for these engines when naturally aspirated. Forced induction, I'd probably got with an HDEO like Delvac 1 5W-40.

This will be a once a year only oil change. Not driven enough to accumulate alot of miles

5 lbs of boost. Stock everything

I'd probably just use regular 5w30 in that case if it was mine. I have owned one of these cars in a similar configuration but I had heads/cam/intake as well, I had an S trim on it.

If it was tracking it or something I would probably use the 10w40.

The old A-trim! Am I right? That was a popular add-on "back in the day". OK, so, definitely not a high HP application, Delvac 1 5W-40 should be more than adequate. I would also suggest he runs the Fleetguard LF3487 oil filter.

M1 0W-40 or M1 5W-40 Euro oil. once a year oil change interval. A HDEO will work as well.

Another for Mobil 1 0-40 or 5-40 Euro. A lot like a stout 30 weight for that engine auta provide all the protection needed for 5 lbs boost.

I run Schaeffer 9000 10w30 oil in a Vortech Renegade / TFS aluminum heads setup.
