What is the definitive answer here? The VW engine has alloy heads and the petrol companies tell us that anything with alloy heads will already have hardened valves and seats therefore can use unleaded, yet they sell kits for ULP conversion on VW engines, plus almost everyone talks about using valve saver.

So what is correct? Do you need to perform a conversion to run on straight ULP?

been covered a few times. you wont get a definitive answer as its all opinions
heres the pervious discussions

and thats just the first page of the search for valve saver

No, they don't need valve saver. Unleaded is fine.

If you want proof, then here's a letter from the UK's Civil Aviation Authority authorising VW-engined aircraft to run on unleaded fuel. If it's safe enough for an aircraft engine, then it's safe enough for me!

selling 'unleaded' heads for the VW is just a sales ripoff.

Basically since the mid 50's the valve seats fitted to VW heads where made of hard enough material to not require lead in the petrol. Earlier than this would be OK for a few thousand miles but would end up suffering if a lead replacement product wasn't used.

What else is there besides unleaded?

Was it after 1967 that ALL VW engines had hardened seats for unleaded?

If you still have a 45 plus year old head in your VW, then it has done well.

I read that it takes about 80000 to 100000Ks to see valve wear.
Whos going to do that many Ks these days in the old VW

What are you doing driving Smiley's car, Jeff?

Smiley, I am married - I am used to 'not leaving footprints', otherwise I wouldn't be allowed to do anything. lol
