'I'm using Aeroshell 120 AD (bought a 55 gal drum of the stuff so I wouldn't
have to look at all the empty quart containers in the trash).

I'm wondering if I can mix 100 AD with this? the 100 is available almost
everywhere, but I'd have to take the 120 with me. I'm planning a trip from
Texas to California in a few months, so you can see that I don't want to
take a hugle lot of oil. I don't know a thing about oil formulas, but I
figure some of you guys can advise me on this. Maybe the best answer would
be to change back to 100 AD before the trip.

'Robert,

As for oil coming out the exhaust, don't worry nature of the beast. I keep
coke cans on the stacks when idle. Running it up to 1000 rpm will not hurt
anything. May help it scavenge better, depends on condition of pump.

As for Oil mixing and cross country. I am still running Mineral Base
(non-Det). I sometimes have to mix in some AD when I am on the road and no
Non -Det around. It will not hurt anything. I would not go to AD oil
completely due to sludge would be become loose and plug up the galleys. As
for mixing 100 and 120 press on, will not hurt anything.

Thanks Jamie for the reply. I'm trying to think how oil gets into the
cylinder head in the first place. Can that much oil find its way between
the piston and cylinder wall? In order for it to come out of the exhaust
stack, it has to be at the bottom (top) of the cylinder head. I'm scared to
death of the dreaded "hydro-lock" that could happen if I tried to start the
engine without turning it through at least two full revs. Also, I assume I
pull the prop through in it's normal direction of rotation.

'Robert,

The oil will normally pool in the rear cylinders. As for Hyd lock. Be
concerned.... You should pull the prop thru at min 12 blades in normal
rotation. Treat the Ranger just like a Round engine. Sometimes I will get as
much as a 1/2 pint out of the rear cyl. I sure love when it starts up and
blows out black oil and blue smoke when that Ranger comes to life.

'Robert,

Forgot to answer your other question. The oil will get by the rings and past
the valve guides. When the engine cools the clearances get larger, which is
normal for an Air Cooled engine. The tolerances must be looser on an Air
Cooled engine compared to a water cooled.

'Bob....glad to see you got your PT-19...still missing mine. Anyway,
there's no problem mixing 120 and 100. I'm not sure there's really a
problem in mixing different types of oil, but I know there's no
problem mixing different weights. When I would go on long cross
country trips I would often have to use the lower weight oil.
However, I found I could carry a case in quart bottles under the front
seat(in a cut down oil box) and more in the rear baggage compartment.
If you're travelling alone you can use the back seat for oil or for
your duffle bag. If you've got a companion you're out of luck.

Another option, if you're travelling in hot weather and want to stick
with the heavier weight oil, is call ahead and plan a stop at a strip
that services dusters that may be able to restock your oil supply.
You may have problems though, as many have switched to Phillips
25w-60. I did for the PT as I liked the multigrade for the cooler
mornings and days we have in the Northwest, but still afforded me the
heavier weight when it got warm or I headed east or south. It was
also more convenient as I could get it in 2.5 or 1 gallon jugs vs
having to buy a drum.

'I agree with Curt. The Phillips 25-60 is all we use. We have friends running 75 hours between changes. We also buy the 2.5 gal jugs. Works great on trips. Our oil consumption went down 3/4 hour on the Ranger just switching oil.

For what it is worth.

'I'm using the Phillips also. Quite acceptable so far!
