Unleaded or LRP on WBX?

Re: Unleaded or LRP on WBX?
ok now I am too scared to put fuel in my bus :shock:

It's been ages since I had to worry about petrol, been driving a Nissan Diesel for the last 10 years

When I got the Caravelle I threw in a few litres of unleaded, I thought this was the only type of fuel I should be using.

do I continue on unleaded fuel? I have no idea if my 2.1 wbx was already running unleaded and if the timing was retarded, how do I tell?

Re: Unleaded or LRP on WBX?
Let me check on the degrees as i haven't done this in a few years. 4 degrees rings a bell but my memory likes playing tricks on me.
I know all 2.1's even the older CU 2L aircooled engines in Europe had the harder valve seats fitted. All these parts that were used in SA were made in Germany so i
would say they are the same.
Now if along the way your engine has had a seat or 2 changed then you will need the dark arts to tell.

Hi all
I hope you are all well
Any further update regarding how far we need to retard the timing for unleaded fuel use?
what should the timing be for LRP and by how much must we retard it? (for WBX 2.1)
thanks

Bad planning on your part does not make your issue an crisis to me
Bad workmanship by other garages does not entiltle you to better rates at me
Syncro, syncro , syncro and more syncro, this is the syncro way of life

The internet say the 2.1 WBX with engine codes .GW and .DJ were designed to run on 98 octane unleaded.
So the 98 octane runs at 10 degrees and to run on 95 unleaded the timing must be retarded by 5 degrees
I hope this helps
