Hi All,
In the few months i've owned my T4 I have used both premium and standard unleaded in the van with no discernable difference in economy or performance. My Serviceman suggested every 2nd or 3rd fill be premium, so that is what I do. Still averaging 11.5 l/100klm (2.5 manual) mainly city driving. Would be interesting what other owners fill up with and why or why not.
Regards
