Just a survey of how much oil your flat four consumes.  Mine's at 95K on this engine and I just topped off a little at my last fuel stop, oil change about 800-miles ago.  I think I have a small leak (oh, really on a bug?) at the rear main seal.

MY72BUG will use somewhat under a half litre in about 1000 miles of summer driving.  I start the season with new Castrol GTX 20W-40 and will top up with Castrol 20W-50 as the summer heats up. ( tough to think of that when we now have about 2 feet of snow ! )  I use new valve cover gaskets every year when I set the valve lashes.  The gaskets go onto the valve covers with a high temperature silicone sealant.  The gasket side to the cylinder head gets a smear of vaseline petroleum jelly. This makes for easy removal of the valve covers.  Nothing there leaks and I virtually never see a drop of oil on the ground where the bug parks.  If you want to see an oil pig, check out my ' 93 Grand Voyager 3.0 litre V-6.  At least two litres per oil change from when the car was brand new!  The van really marks its territory.  I think of it as cheap rust proofing and it's hard to complain when the poor old thing has 345,000 km. on it without any engine work other than two water pumps.  Dan (MY72BUG) in Goderich, Ont.

I consume to much oil. my piston rings on No. 3 are bad so it leaks threw and smokes so bad and there goes all my oil. :-( good thing im putting not only other pistons in there but bigger. i use 20-50 in there cause it doesnt get to cold here or to hot.

Hi,
Castrol GTX2 20W 50 is used by Many VW owners in Australia.
some engines use more oil than others, but You do need to check VW engines more often, as they don't have a lot in the sump...
so nothing in reserve...
 
You could do a cheap overhaul, and replace that cylinder/piston etc
with a good used one...
 
cheers

VW's don't leak, they mark their territory.

If you're looking for a little more volume and cooler oil temps there's a couple things you can do.  First of all, get rid of the cooler inside the doghouse, which will cool the left side cylinders better.  Put an external cooler on it, and use the fan to pull air through it.  I mounted mine just slightly above center of the opening for the fan on the doghouse so as not to obstruct too much air intake on the fan.  These things have extreme head temperatures on the mildest of engines, and need a top quality oil (such as the Castrol GTX 20W50) to keep 'em slippery inside.  Along with the cooler, add on an external filter, and swap the wimpy stock pump for a high volume pump.  This bumps the volume from 3 quarts to 4 (33% increase in volume) and helps with the cooling in a larger cooler.  It also adds additional filtering which will make the internals last a lot longer.  One other thing, if you're running an undersize power pulley (degreed pully), expect it to run hotter.  Smaller crank pulley = lower fan RPM.

If you live in warm climes as I do, lose the baffles in the bottom of the doghouse too, along with the "thermostat" bi-metal spring that operates them.  I sacrificed a newly rebuilt 1500 to a broken thermostat which let the baffles close while running down the interstate.  Those things are about as useful as a screen door on a submarine in Alabama.  It takes a little longer for it to warm up in winter, but it WILL warm up.

Hi,
If You go for an external oil filter...
I would mount it near the gearbox...
where the air flows...
Having the external oil cooler over the air intake fan
means the intake air is Preheated with the hot oil cooler...
I've never seen one of these in Australia...
 
I have an external oil cooler with which I added two electric fans..
 
but I have never fitted it or the thermostat or oil filter...
 
Taking the baffles out is a bad thing, VW designed them
and they distribute the air where its supposed to go..
a thermostat cannot over heat an engine if it fails
as the spring pulls the flaps OPEN....
 
I have added everything excepting the new thermostat...
as I'm having second thoughts whether its needed
even in the winter months...
 
the doghouse oil cooler works on engines up to 2 liters....

Hi Patrick,
Change your engine oil every 1000 miles as recommended by VW Mexico...
We have been doing that in Australia for over 30 years...
Your engine will last longer...

I've been changing oil between 2500, and 2900 miles.  In Mexico they recommend 1000-miles, aye Chihuahua!  The Valvoline Racing 20/50 I use is almost $4.00 a quart.  Oh, I guess that's pretty cheap at only 3-quarts.  Unlike my Dodge Cummins Diesel that takes 12-quarts .  I'll be at 100,000 on this engine in 20-miles.  I don't think the oil is even dirty at 1000 miles, I'll keep an eye on it, thanks for the valuble information. Hey, how many miles do you think I can keep her going?

Hi Patrick,
 
its been common practice to change engine oil every 1000 miles in Australia since the 60s...
 
Your engine should last 150,000 miles... possibly more...
especially if Your engine oil is clean...
 
back in the 50s, Volkswagenwerk used to give a medallion to any Volkswagen owner who had done 100,000 kilometers..
 
They stopped giving them out when too many owners were doing 100,000 miles...
and oils are much better than they were back then...
 
cheers
