MrO Posted November 20, 2006 Report Share Posted November 20, 2006 Do the likes of Shell Optimax and BP Ultimate really make a difference to your cars performance or is it just advertising guff? Before I took delivery of my new wheels over the weekend I know the car had been sitting on the forecourt for a while. Will the likes of Optimax and BP Ultimate really clean out the engine or just my wallet? Link to comment Share on other sites More sharing options...
patently Posted November 20, 2006 Report Share Posted November 20, 2006 Opinions differ. My experience is that it did make a difference when I switched - I felt (subjectively) as if the accelerator pedal now went slightly further, and the trip computer reported 28mpg instead of 25 mpg. Others disagree. What do you drive? It seems that V-power (new name for Optimax) etc only really help with a higher performance engines. Link to comment Share on other sites More sharing options...
MrO Posted November 20, 2006 Author Report Share Posted November 20, 2006 I have a Celica, so far I have only filled it with Optimax/V Power (the dealer paid). Other than the two I have mentioned do any of the other fuel companys offer performance fuels of note? Link to comment Share on other sites More sharing options...
drpellypo Posted November 20, 2006 Report Share Posted November 20, 2006 Tesco offer a 99 ron. I usually every three or four tankfulls, stick optimax in the GTI, and it makes little difference to the performance, but the engine does sound less 'clattery' and mpg seems to go up. You never really know how much of a placebo effect this is though. Link to comment Share on other sites More sharing options...
AvantSE Posted November 20, 2006 Report Share Posted November 20, 2006 I had an Impreza WRX that pinked like mad until it was fed Optimax or similar high octane fuel. So yes, on highly-strung cars like the Impreza running slightly higher boost, it did make a difference. Link to comment Share on other sites More sharing options...
sufu Posted November 20, 2006 Report Share Posted November 20, 2006 Mines only the old 1.8T, but it does make a difference, both in terms of smoothness and mpg,. both of which are improved. Don't expect big improvements unless you've got a highly tuned car Link to comment Share on other sites More sharing options...
xkjaguar Posted November 20, 2006 Report Share Posted November 20, 2006 i used to work for shell uk on tankers and we regularily delivered petrochemicals (various) from a bp field to texaco refinerys and other combinations basically all the fuels are about the same Link to comment Share on other sites More sharing options...
P_G Posted November 20, 2006 Report Share Posted November 20, 2006 If your car is designed for a using a higher Octane fuel I imagine you will get the gains. I know in my car V-Power does make a difference in responsiveness and slightly better mpg as well. Link to comment Share on other sites More sharing options...
a4andy Posted November 20, 2006 Report Share Posted November 20, 2006 I 'think' I get slightly better performance on V-Power / Optimax (as was). It's so marginal though that I might just be imagining it. I have a 2.0 FSI so you can't really expect too much. What is measurable though is the extra 1 to 1.5 mpg I get from it compared to the regular juice. It pretty much cancels out the premium you pay for it, plus it supposedly cleans the engine so it's all I use. Link to comment Share on other sites More sharing options...
Ian_C Posted November 20, 2006 Report Share Posted November 20, 2006 [ QUOTE ] V-Power / Optimax... supposedly cleans the engine so it's all I use. [/ QUOTE ] Same here. Probably doesn't make my car any faster - my 205 is too old to have knock sensors to advance or retard the ignition. On my fourth tank now - incidentally from a fourth different Shell garage on my adventures. Just 90.9p in Milton Keynes! Ian Link to comment Share on other sites More sharing options...
sayerbloke Posted November 20, 2006 Report Share Posted November 20, 2006 I used Optimax because my MPG averaged about 24, instead of 21, which I used to get on 95ron fuel. It also seemed a little more refined and quieter at idle, but I can't be sure. However, over the last couple of months, I've found out my car doesn't like VPower or Tesco 99. Back to the drawing board, I guess Link to comment Share on other sites More sharing options...
