Juggalo Posted October 10, 2015 Author Share Posted October 10, 2015 How do you know it was down to fuel octane? Quote Link to comment Share on other sites More sharing options...
Stutopia Posted October 10, 2015 Share Posted October 10, 2015 (edited) I'm confused, that bloke is on about power and torque, I was under the impression octane rating of fuel is all about delaying detonation under compression. This looks like bad science. Edited October 10, 2015 by SuperStu Quote Link to comment Share on other sites More sharing options...
brillomaster Posted October 10, 2015 Share Posted October 10, 2015 surely the summary is pretty clear 'While it's true that some car makers recommend putting premium fuel in their high-end models, what about most of us who drive regular cars?' the zed isnt a regular car, its a sports GT where the manufacture specifically states 98ron or better. yes, putting premium in a car thats not designed for it is a waste of money, but if your car says to use premium only, you'd be wise to do it! 1 Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted October 10, 2015 Share Posted October 10, 2015 (edited) The simple answer is that fuel octane among other things denotes knock resistance,, so using a fuel with a lower knock resistance when the manufactures specify a higher one is asking for trouble.

Ricey Posted October 11, 2015 Share Posted October 11, 2015 How do you know it was down to fuel octane? Best guess.....you'll never really know but we've enough forum cars having problems and the most common and consistent way that people could be causing the issue is through use of wrong fuel. Don't forget a knock sensor has to detect a knock first before altering its mapping which means detonation has already taken place. If the car says use high octane then you need to use it.....period. If your mousing round in a Nissan micra that doesn't need it then yes there is practically no advantage to sticking high octane fuel in.

I'll have to try and find some of those threads, sound interesting. And apologies guys, I didn't mean it was a con for performance cars, I meant it was a con for the regular car driver; that it does anything useful for them. I'll still be running premium in my Z.

Ricey Posted October 11, 2015 Share Posted October 11, 2015 Absolutely pal. The manufacturer's do give the average car driver the snake oil treatment about 'more power' and 'better fuel economy'. Essentially it's all about not blowing your high performance engine to smithereens. That said plenty of sports cars don't need high octane either Sent from my SM-G900F using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
