What weight oil do you recommend in a stock Type I with outside
temperatures ranging from
42 to 68 degrees F
or
5.55 to 20 degrees Celsius ?
This vehicle is used mostly for short 3 mile trips, to the grocery
store usually once a week, going about 35 miles per hour/ 56.3
kilometers per hour.
Several old timers keep telling me to keep using straight 30HD in it.
Thanks in advance!
If your car has a full flow filtration system I'd think seriously
about running one of the lower priced synthetics, say Pennzoil Platinum
which can be found on sale at some really great prices. Pennzoil
Platinum is a highly refined Group III (hydrocracked/hydroformed) oil
that sticklers will contend is not a true synthetic (which is true since
it does start with crude oil) but these modern Group III's give you 90%
of the advantages of a full synthetic (Group IV or V) at a substantial
savings in cost. Since the Type 1 motor has a vented crankcase you
really can't go with the extended change intervals that a full synthetic
will run even with a real oil filter in the system. If you don't have a
full flow filtration system I'd probably stick with a good conventional
oil such as Pennzoil in the yellow bottle and go with 2k to 3k mile oil
change intervals.
There is absolutely no rational today for using a straight weight
oil. Modern multi-viscosity oils are vastly superior to the straight
30wt oils that were in common use when these cars were new. If I'm not
mistaken even Muir in his "idiot book" recommends multi-viscosity oils
and the multi-vis oils available today are vastly improved from the
muti-vis oils that were available in the late 1960s/early 1970s when he
wrote his book.
It used to make the creamy, frothy foam on the bottom of
the oil cap when I was using a 1.5 quart bolt on oil sump.
But, it hardly ever does that.
Would it be OK to drive it around the block until it idles at 900 rpm
and then let it sit and idle on the driveway to let it warm up before
driving it?
...thanks again!
The flaps and thermostat help the heads warm up, but don't really do
much for the oil. Might be different for a non-doghouse engine.
Better to take it for a nice 30-minute drive where you can put some
load on it.
Max
The aircooled Vw engine should not be left idling when cold at all..
Drive away after after 30 sec or so and drive it a modest load and revs
until warm.
This is per factory recommendations.
I Have original Owners manuals from 1954, Aug.-66 and Aug.-72. They all
list single-grade oils.
If you choose a 20-30w or 20-40w of decent quality you are good to go.
Originally listed is:
Tropical areas:
Hot season: SAE 40
Cold season: SAE 30
Moderate climates:
Summer: SAE 30
Winter down to -15 Celsius: SAE 20w-20
Winter down to -25 Celsius: SAE 10w*
Winter with temp. sustained below -25 Celsius use SAE 5w.
*: Avoid long trips at high speed using SAE 10w above -10 Celsius and SAE
5w above -20 Celsius.
Cut, paste and save.

use as a guide, maybe, but not gospel... the newest information you have is
based on what was available 37 years ago.
Soon, I will change over to Castrol 10 W30 for the cooler weather.
....thanks again!
----------------------------------------------------------
Not gospel, hence personal advice of 20-30w and 20-40w.
Merely listing the original recommendations.
I understand that they are the original specs, just throwing it out there
that oil technology has improved a little over the decades for those that
may take the factory specifications(at time of manufacture) as gospel...
There is another often(always?) overlooked issue with modern oil in an
aircooled Vw engine.
The single-grade oils where formulated to not keep contaminants/debris
suspended in the oil, but to allow them to sink to the bottom of the sump.
This should be considered when running a stock setup without an oilfilter.
A modern oil will keep contaminants/debris suspended to be filtered of by
the oilfilter, which you don't have on a stock engine..
If you look into tech manuals for the Citroën 2CV this is clearly lined
out as the engine at a certain stage where fitted with an oilfilter, and
they list different oils before/after this change.
So in short, a stock Vw aircooled engine will se more wear running a
modern detergent oil..
Not at all correct. All grades of oil started adding detergent in the
1950s and only non-detergent oils do not suspend contaminants. None of
my VW books recommend non-detergent oil not even the often wrong idiots
guide.
Tony
The term detergent was wrongly used, yes. But I had already hit Send..
The bit about suspension of contaminants and debris is very much correct
though.
Jørn
Yes, I know all about the Zink bit.
The Diesel single grade(or multi grades for that matter) oils are the best
bit for the aircooleds these days, unless you go with Rabys findings and
his local/small producer.
Cant remember the name now, the info can be found on his pages.
Returning to the matter of flat tappets,(which are not flat..) a well
broken-in engine will not suffer cam failures because of lack of zink. The
tappets and cam have been hardened over so many years..
It applies to new engines built with a new cam and followers.
I would still go with a single grade oil as these are less prone(these
days according to some) to suspend contaminants and debris.
Must admit I ran my engines on new formula oils myself before being made
aware of the non filter vs. filter and suspension of contaminates.
To cut short, non stock setup with filter you can use whatever type(not
weight) you want, non filtered, go with tractor type oils.
There is a reason for the large oil drain plate and screen at the bottom
of aircooleds.
J.
VW seems to have disagreed with this point of view.
From the 1965 Type 1 Owner's Manual (page 36):
HD oils are prescribed for the engine lubrication. HD oil is an oil
with proven oxidation stability, bearing corrosion preventive properties
and detergent-dispersant characteristics which tend to hold in
suspension foreign contaminates which would normally deposit on engine
parts. These foreign contaminates will drain out with the oil at the
periodical oil changes. The detergent properties of HD oil will make the
fresh oil darker after a short time of operation. This is quite natural
and there is no reason whatsoever to change the oil earlier than called
for in the Lubrication Chart.
When I removed the sump plate, four of the six small studs came out.
The holes are not stripped, the studs just came out with the nuts on
the ends.
I plan to get a new set of these studs, well at least 5, and red
Loctite them in on the next oil change.
By-the-way, I read somewhere that the zinc additive is mainly
necessary for use with high revving performance engines.

you can't get the oil that was around back then... you even acknowledged
that in your post.

You can come pretty close...30wt HDEO. Again, these motors were
designed when 30 and 40 wts were the norm. Just about all of the
"typical" oils (i.e. Castrol GTX, HD, Valv. Penn, etc.) are nothing
like they were even 5 years ago. Also, my experience with 4 & 6cyl
Porsche motors is that some of the multi visc. oils, when heat cycled
a couple of times in a comparitively high-temp aircooled motor, tends
to revert to it's original state (a 20-50 for example, tends to revert
to a 20 wt, losing a good part of its viscosity additives.)
If you haven't, go to Bob is the Oil Guy . com and check out the
thousands of posts on this specific subject. You'll find that a
substantial number of the posters prefer a very low viscosity
multiweight in a performance, aircooled motor - even under track
conditions. Now look at the cars they list as owning: Saturns, Toyota
pickups, etc. Always easy to give "cutting edge" advice when someone
else is out there picking up pieces of a fragmented motor.
Bottom line is the choice is up to the individual owner. At the risk
of being oldfashioned, I'll stick with a one-piece crankshaft.

yep, I've always said, folks are only "set in their ways" because it has
"worked" for them... that said, i've run 10-30 castrol in my aircooleds for
many years... and I, too, like my crankshafts in one piece...<G>
one is a type one powered John Dear lawn tractor about half done its
to much fun. and riding around on a Motocomp siutcase scooter. This
one was shiped from Japan.
stay tuned for our next exciting episode where we talk about how a 16
yr old hit me on the way to the lake.
what I get for typing while bidding for stuff on e-bay
I use castrol diesel oil in my 64 and change it often

of course not, sanding blocks and spreaders come in bulk...
