Which fuel?

Old thread i know, but having looked in the owners manual it says you should run your ls400 on 96 or higher which explains the difference i get between momentum 99 and normal 95

Have been using Tesco Momentum for long enough to let the old girl (LS400 Mk1) get used to it, and she is very happy with the performance over the "cooking" grade. By the way, a week ago I filled up at ASDA in Brighton Marina, being a bit short for the journey home, also out of curiosity, as it was dirt cheap (relatively!) at only £1.10(.9) litre. What the grade was I couldn't see - they only sell the one - but the car runs surprisingly well on it! Not too many ASDA fuel stations where I live but if anyone has one near them, there's money to be saved!

yes it will as its still running on the super unleaded map, but it will soon go flat as the ecu retards the timing ect ect
