Gday guys.
Something iv been trying to understand for the last little while, done a bit of a search but still a little unsure.
I don’t usually pay a whole lot of attention to where I fill up - generally go to the cheapest place but it always confuses me when I end up at bp or shell and they have the bp ultimate diesel or shell v power diesel or whatever it is. What’s the go with these fuels? Is it just another hyped up name for diesel? Generally the blokes behind the counter are little to no help at all.
Correct me if I am wrong here but I have read that in the last ten years or so the sulphur count of diesel has been significantly reduced hence lowering the lubrication of diesel. So my question is what should I be putting in my 06 4.2tdi?
Is the shell and bp stuff ok or should stay clear? Should be adding like a valve lubrication (similar to what I used to run on my lpg vehicles)?
Sorry if these are dumb questions, just hard to find the correct answer!
Cheers
