After getting lost searching this topic am now being lazy and going to ask instead (sorry).

I have had my GS300 for just over a week now and still getting to know it. Has anyone worked out the best fuel to use and whether there are any pros and cons to using unleaded or super unleaded?

What is the average mpg you are all having? mine is the 1998 model (mk2?)

hi
i've noticed that 99ron from tesco lasts longer than 95. the car also feels faster

V power. I use 10% less fuel with this product.

Hopefully not a silly question, but does using 99ron or vpower have any detrimental effect on the engine?

not a silly question, and in my opinion it has no ill effect on the engine. the ecu adjusts the timing to cater for higher ron.

What is the price difference between V Power and regular unleaded?

About 4 or 5% more to buy.BP now have a 102 octane petrol,but no idea about how it would perform.

Have you seen the price of it tho????
Plus the car would need to be re-mapped to make the most of this fuel

I wouldn't pay the extra. Mine has run very happily on ordinary unleaded--normally from Morrisons.

I use Vower in my other cars but my GS came with a full tank of petrol and would think that it was 95ron but was wondering the same thing, if V Power would be better.
