As a TT Newbee,(sorry to keep repeating this fact but i feel it justifies the naievity of some of my questions) is it worth paying a bit more and putting in Super unleaded fuel?

This isn't quite right. The reason high octane fuel isn't required in the V6 is because it's not a turbo and hence the compression ratios are lower and there is less chance of the the fuel mixture detonating earlier.jimfew said:Actually it makes a difference if you have a V6 or not. Super type fuels, optimax, ultimate and five stars, work well on most except the V6 because it has a power limiter function in the engine management system to protect the DSG box (not sure if this applies to the new V6 manuals though).digimeisTTer said:As a TT Newbee,(sorry to keep repeating this fact but i feel it justifies the naievity of some of my questions) is it worth paying a bit more and putting in Super unleaded fuel?

However, I still use Optimax even with a V6 DSG because I am stupid! :lol:

If you believe Shell marketing :wink:XXMetal said:Even if you have a V6 I thought Optimax was better for you engine, I thought it had a cleaning agent.
.......maybe, but I was loosing 4mph over a tank of Optimax compared to 95RON and the car didn't feel as eager to pull and all this was costing me more money! I gave it up after 6/7 tanks.......XXMetal said:Even if you have a V6 I thought Optimax was better for you engine, I thought it had a cleaning agent.

Due to higher compression in the turbo'd engine, it is recommended to use a higher octane (98)
nothing to do with power limiting. You can put 98ron in your v6 but it shouldn't make any difference...however the extra additives in some fuels i.e. optimax may but in a different way.
My 225 loved the stuff.graham225 said:i definately feel the diff with Optimax 8)
