umm. ok. my car has had no oil change for at least 20,000km's. lets just say it was my bros car and he is not mechanically minded.

and also. are the 1600's able to run premium or even unleaded?

i run standard unleaded with flash lube or lead replacement fuel with no additive. i actually dont know what oil is in there ATM becuase the last oil change wasnt done by me however i will do an oil change before valla which will be GTX2.

so if u run unleaded you should run this flash lube stuff?

flash lube is just one brand of valve lube.......it replaces the extra lubricants that are in lead replacement petrol so u can run unleaded through your engine......i dont know if it helps alot but i use it.

not all vw have hardened valve seats only the ones that have ether new performance heads or heads that have been converted to unleaded. cause the original style valve guides were softer due to the lubricating effects of lead in the fuel. with the new fuels lead has been replaced by ethyl benzine which does not lube valve seat and shafts

I run a 96 octane gas with no additive and 32 degrees total advance with 9:1 compression. Never had any pinging. I have never run any additive in any VW engine, and never had a valve recession problem.

As for oil - my understanding is all the additives that modify an oil to make it multigrade break down pretty quick, so you may as well buy a standard 30 weight oil and call it quits. Put the money into something else - like beer.

Youll find that many of those dudes are just dazzling themselves in science.
VW's are just not rocket science. With such low specific power outputs and low rpm's the damned things will happily run on about anything that feels oily.
There is so much verbal diahorrea regarding oils for VW's as to what one particular dude reckons is better than an other and some almost preposterous claims made by some dudes as to what may or may not happen if you run some fancy jungle juice or other. I find it laughable when some oil is the next great thing and "my engine runs smoother, starts easier, gets better fuel economy and bloodywell detonates a whole lot less than before"........bah!
These claims are often based on recollections and anecdotes from their mates who"had a ""mate"" that knew some bloke that ran some fancy multi-vis, ipso-facto, chechomahoota minus 10w-330 oil in his engine and the engine simply disintegrated in a puff of logic".
Usually heresay and the bulk of the failures attributed to lubrication (or lack of it) may well be traced to a big end cap bolt failure or some other far less sinister metalurgical failure.
gawd, i remember when I bought my first bevel-drive Ducati Vee-twin.
All the nay-sayer came out of the woodwork with the tiresome and repetitive accounts of one of these mysterious "mates" who "had a mate" who spent more time pushing his Ducati than riding it due to, big end failures every six months or electrical gremlins in the old italian electrics...........................
When quizzed more closely, these said "mates" can never be found, if they ever existed and indeed most of them had never even had a mate that owned a Ducati......
All of it is bullshit and the failures are almost always a result of bad or non-existent maintenance.

Hey Tassupervee,

I am no expert on oil or petrol and only try and make educated decisions on what I read. The comment I made earlier about the synthetic oil rejecting heat was firstly from an article on 4 dyno tested 2000cc+ aircooled engines. All of their head temps went up with the use of synthetic oil. I then read this ......

OIL10-ND Non detergent 10 weight for break-in of new engines in cold weather.


OIL20-ND Non detergent 20 weight for break-in of new engines in normal weather

OILR/30 Racing 30 weight


OILR/40 Racing 40 weight


OIL-GR Gear oil 85/90 weight


OILM-GR Synthetic gear oil 75/90 weight.


Note 1: Synthetic gear oil will provide the best fuel mileage, smoothest shifting and longest life. For all standard transaxles. Do not use with a ZF limited slip.


Note 2: We do not sell or use synthetic engine oil for the air-cooled VW as it rejects heat. The air cooled VW depends on the oil to soak up the heat from the head and carry it back to the oil cooler. With the synthetic oil the head temperature goes up and the oil temperature went down.

I am doing some testing on a new development in the synthetic engine oil that is advertised to pick up heat from the oil and take it to the cooler without viscosity break down. I will let you know in the future if it lives up to its claims.

Dude
Be assured I was not pointing the acid tongue at you or any other dude on this forum, generally just some of the claims and stuff I have read ( and laughed out loud at) over the years regarding oils and fuels, and not just on this forum.
The "rejecting heat" claim is a very curious one as this flies in the face of the very properties of nearly any decent, FULL synthetic oils.
Remember, that up until relatively recently, many so-called "Synthetic" oils were not full synthetic at all. Just blends of minerasl oils with synthetic compounds/polimers/molecules/atomic paticles :blah added.
Mobil 1 was one of these despite the claims of being a "Full Synthetic"
How they were getting around this blatant mis-representation is beyond me but probably runs along the same preposterous lines as the old "Made in Australia' & "Product of Australia" both which qualify for the green triangle and both infer being australian made but in fact are not even closely related......other than available in Australia..............go figure

Again, the science of tuning a kraut is not a rocket one. Low specific power output, low RPMs and low bearing loads. Compare a kraut to any of the air-cooled Nipponeeze big inch bikes of a few years ago. These things were producing around 130 Hp/litre (some more, some less) at 12000rpm and well beyond and seemed to survive for many tens of thousands of kilometers on anything from straight 30 weight deisel oil right thru to the very best synthetic stuff from Redline and Amsoil.

These things are asked to perform in a hideous environment of varying airflows over/around the engine, hidden away under a blanket of fibreglass rather than having the luxury of fan forced cooling and survive well enough on whatever happens to be put in them.

So, the moral is for most of us not to get too bent out of shape over the (supposed/claimed) quality of a given oil and its supposed heat rejecting properties (I notice that the article did not quote what oil it was actually running) How old is the article?

Anyways, good luck with your new toy.

If it burns it goes in my tank. If it's slippery it goes down the oil filler.

What's this about VW's having hardened valve seats? I was (i'm no expert here) under the impression that they didn't have them and a additive was needed. I've been using flashlube for more than 2 years had no problems.

I'm not trusting the people who put the seats in my heads to have put a specifically hardened metal in there. they could be cheapies... they could be kickass titanium or summin..how do you really know? one way to find out is not to use an additive that costs about 12 bucks for every 500litres of fuel you use. but that could work out realll spensive, so I'm sticking to flashlube. don't use valve seat protection, by all means, but check your clearances every so often and watch for the telltale signs. for those of use running dual valve springs and even triple valve springs I'd think it would be a good idea too. flashlube. mmmm. tasty.

Bwaaahaha a man after my own heart.

A point to ponder is that flashlube and other lead substututes are not there to lube valve guides and other parts but purely as a cushion or shock absorber between the valve face/seat.

Sadly, spring loaded poppett valves dont close with a neat single click as we would imagine (hope for (dream about)) but with a nasty, uncontrolled and ever decreasing buzzing consisting of a multitude of tiny openings and closings.
This nastiness can be (sort of) demonstrated by gently bringing the faces of two hammers together.
(Dont do this hard tho children as hardened hammer heads have been known to shatter when hit against each other hard enough)......

These nasty and uncontrolled repetitive closings result in high wear rates and the dreaded valve recession, not to mention in extreme cases removing the heads off valves, collet and retainer failure, broken springs and so on.

This fun and games is a result of the combined harmonic properties of the valve spring and the valve train components.

A very common way to deal with these harmonics is to employ double or even triple valve springs as the different resonant frequencies of the different springs, combined with the other valve train components act agains one another effectively cancelling/reducing/eliminating this destructive bouncing of the valve on closing.

The seating pressure of the valve is but one condition that affects valve seat wear and what will really do the job on valve train goodies is destructive valve bouncing and badly profiled closing ramps on cams resulting in the valve slamming shut.

All that mega seating pressure and multiple springs clobber will actually prolong seat/valve faces, rather than contribute to seat recession.

Seating pressure alone has little to do with valve control and springs can be wound in a variety of linear and progressive tensions and simply upping the seating pressure may not control a valve at high lift.

As a matter of interest, in F-Vee, some guys are using springs seated at as little as 55Lb seating pressure and controlling the valve at up to 6500rpm. Mind you this is on a stock camshaft.
I personally use 65-68 Lb seating pressure on box stock springs and my engine will happily run to 6200rpm
Pandy's F-Vee will top 6500rpm with the same seating pressure.
Everything sure changes when very aggressive cam profiles are used but the basic rules apply right across the board.

Happy oiling.......FWIW I use Castrol Synthetic 0w30 in the F-Vee as it is cheap and available everywhere. I change it twice a year.

Come on people everyone has ther own opinion, one says this one says that.. at the end of the day we drive volksies and as much as we all love them they leak the oil right back out on our nice driveways and shed floors... they dont call them oildrippers for nothing hehee..........at the end of the day as long as it runs and gets us where we want to go it works... Myself i add a small amout of castrol tts 2 stroke bike oil into my tank.. why?? well i use it on my motorcrosser and i always have some fuel left over from a days racing so it goes in the beetle :P:thumb:P

Yeah theres nothing wrong with a bit of 2 stroke oil mine gets a bit of motul 800 mix after each ride
