Is it better to put premium petrol in my fasty rather than unleaded? And should I be adding the lubricant to both types, or just unleaded? Im new to the car scene so any advice would be great :-)

Premium unleaded in my 2.0 Bus mate for sure. LRP is shite. Had no hassles at all with it in 4 years.

I use premium unleaded with no additive in my fastie and beetle, and have had no problems so far. My fastie has had it for the past 2 years.

premium in my beetle no additive, I get more kms out of a tank so it works out about the same $. been doing so for about six months with no noticable valve problems

I have been using standard unlead since 2001 in my superbug.
No additives at all.

I may try the premium unlead just to see the results.

Dave try the premium mate.
the regular unleaded hasn't got enough octane rating.
just go the premium with or without aditive your choicenn[ Edited on 7-7-2005 by manx_xtc ]

Their was a dedicat speal on this subject some time ago by someone who new heaps about this stuff.
But the basic gist is the VW started running hardend valve seats in the 60's so don't need the lead in the petrol to lube them and it depends on your compresion ratio as to how much octain you need. Modified engines generally run higher CR's so be safe and run 98ron fuel. Were std 40hp motors should be able to run regular unleaded.

This is just a basic understanding of what I have read on this forum I am by know means an expert on this subject.

Seats can be OK -it seems to be guides that are problem without additive,
I use premium in 2 litre Kombi and 280E MB with splash of additive occasionally.
No problems in 2 years. Vortex does not seem to be as good.

so, you might as well use the 98 RON? not 95 RON?

what he said , remember vw specify 91 octane(ron)which coincedently is what aus produces as standard unleaded,this will suffice for stock engines .
