Concerned about running engine in... but only fuels up with cheap stuff when the car wants Super.

You'll get better protection long term using a premium fuel and more power per gallon.

If I am not using a limited rev range, no need for the super unleaded. Now the engine is bededed in a bit, Yes super unlraded when I can get if. True you can get slightly better mpg. My wifes i30 loves super unleaded, she is amazed at the increased mileage per tank- and so am I.Just strange the torque dip is more noticeable. Have got between 125-175k from my other cars, so I expect the 86 to breeze through 100k. Hell make that 150k. Talk from the dealer 'don't habe to run these in', I will take with a packet of Saxo.

You realise that it's not just about better mpg? Our cars have a high compression engine. On regular unleaded, that causes knock, so the engine adjusts the timing which reduces power - it'll run like a bag of nails, in essence. (Edited to add, the loss of the torque dip could be because you've reduced the torque peaks)

Feel free to correct me someone, but I'm not aware of any Hyundai engine where super is necessary, particularly in the i30. It's most likely a placebo effect if your wife thinks there's a difference.

It's your train set of course, but I don't understand the logic of buying a comparatively expensive performance car and then taking away some of that performance by trying to save yourself a couple of quid on a tank of fuel (especially when the saving is diminished by worse mpg).

I use Shell V-power everytime I fill up, obviously if I'm stuck I'll stick some 97/98 octane in it, but only a small amount. The GT86 runs a lot nicer on V-power and I personally can feel the extra performance especially on the higher RPM's. Plus V-power also helps clean your engine and keeps it heathy. So it's a win win situation!

My wife has noticed serious fuel consumtion beneifts on a long journey to and from her folks. Fills up there with standard fuel and gets back home with 1/4 of a tank (going by fuel gauge). Super unleaded, returns home and it reads just under half a tank. As mentioned using limited revs running in but now using more of the rev range super unleaded it is. With my other cars, supermarket fuel diesel and petrol, feels rougher. I try not to use if. Have not seen momentum fuel.will look out for it.

Tried the momentum fuel, but I feel the V power maybe better. Very little fuel consumption difference compaired to stanfard 95 fuel. Maybe 1+ mpg. Finished the sound proofing, and it is now up to a standard which makes the 86 just OK. Up to 50mph fine. 60 mph OK and above that acceptable. Remember rhese are cruising speeds no just at the sped for a few minutes. Main thing, The noise of the engine in the torque dip was annoying, and I found myself short shifting. Withe the added sound proofing in the floor wells, I find I am not unconsciously short shifting and using the rev range more. Sound deadening sorted, audio sorted. Maybe torque dip next!

I actually find the Esso premium stuff best. Using that for a few weeks and the fuel pump chirp goes away completely as well (if you don't have this yet, you will). Back to V-power and it comes back.
