[T2] Oil Change - which "style"

[John Burneskis]

Vehicle:

'78 camper. Engine was refreshed 4,000 miles ago; rebuilt heads, new P&C.

Engine was rebuilt by California firm,subsequently suffered water damage as
a result of 2 years neglect after a minor engine fire. The case was 'split'
by my mechanic, in front of me, and bearings were measure, and our opinion
was that no other machining was necessary.


Situation:

Oil / filter was changed @ 2,000 miles, after break-in, with 30wt oil, as
recommended and performed by mechanic in Holiday Florida.

Now the '78 is sitting in Virginia, at 4,000 miles with the 30wt oil.

I will take AMTRAK AutoTrain from Lorton VA to Sanford FL this Sunday, and
drive around Florida (East coast) 10 Feb - 9 Mar, probably 2,000 miles.


Question:

Before my trip, I want to change the oil. What oil should I put in?

(1) Castrol 10-40wt

(2) Shell Rotella 30wt

(3) Penzoil 10-30wt

(4) Other?

Thanks  Barry Burneskis sends
