So I started filling my car up with Optimax a few wks ago after advice on here and a few other places and have now seen a massive difference !
If you;
1) Do the speed limit on the motorway
2) Put 99 Octane in your car
3) Have a stage 1 remap
You will get a decent MPG !
I'm averaging around 38 - 39 MPG now and when I check the trip computer it says my tank when at 3/4 full is worth 335 Miles.
I'm adamant that when I was on 95 octane that when I filled up full it said 340 or 345 miles I was good for. I reckon with a full tank it'll prob read somewhere around the 400 miles mark !
Many of you will undoubtedly know this but I thought I would share the knowledge !
