I use Volkswagen's own brand semi-synthetic 'Quantum Synta' in my 84 Golf 
GTi, and I and the previous owner have been using this since 1989, when he 
bought it with 50000 miles on the clock. Quantum Synta costs $10 a gallon, 
and we have both changed the oil every 5000 miles (at $10 a gallon this is 
no hardship - Mobil 1 here costs $45 a gallon!).

It has now done 230000 miles, and it has no bore or bearing (or any other) 
wear, and the only engine work it has ever had was valve stem oil seals at 
210000 miles (that's how I know there's no bore wear - it's a head-off job).

Does this tell me that VW's semi-synthetic is great oil, or that more 
expensive synthetic oils are a waste of money, or that fully synthetic isn't 
worth bothering with over semi-syn, or that it was a good idea to buy a car 
whose interior and exterior fitments, and its wheel bearing and driveshafts, 
etc (3 out of 4 bearings and all the CVJs are still original, despite our 
stringent inspection regs) were of the same quality as its mechanical ones 
(so that everything else can last as long as the engine - which is is 
doing) - or just that VWs are incredibly well-engineered?

I kind of figured that a company with a reputation for durability like VW 
has would not put oil in its engines from new and at services unless it was 
exceptionally high quality - and I seem to have been right. So far, anyway - 
I am shooting for at least the 1/4 million mile mark, and I would like to 
get to half a million!

Cheers

Alan

On more letter on synthetic oil.
My first new car was an 85 Ford Tempo, used Mobil One from first oil change. 
Nine years latter was time to retire it.  Engine was still good but 
everything else was failing.
Changed oil twice a year, (10,000 miles).  Only needed to add oil once in 
between oil changes from when it was new to when it had 180,000 miles.  It 
had lots of one mile trips in Minnesota  winters.  My Neon was similar but 
over 215,000 miles and the car was in much better shape.  Now would cheap 
Wal Mart oil have given me the same results, no way to know with out a 
scientific double blind test.  So which oil to I use on my new car?  I just 
don't know. My conclusions are people change oil way to often and
there is now way to tell quality of motor oil until it's too late.
