Polo GTI - Do you have to use 98 RON?

[clone_tk422]

Hi,

Just a general question about the fuel. It recommends using 98 RON.

Now I probably will use it as its only about $4-$5 difference a tank and for the amount of money i budgeted each week for fuel, I will have enough.

However I have noticed you cant always get 98 RON everywhere so theres going to be times on the road when I cant or maybe if theres a crazy price different of $10+ more per tank to fill up, I might start thinking twice

so question is, will using normal unleaded or 95 still be ok, will it be ok now and then or what about if you only use unleaded..

I'm assuming using normal probably gives you less km's per tank and not as much power but will it void warranty not using it? Also I'm guessing it would leave more fuel deposits in the cylinders as it cant burn as hot??

Thanks

Inside the fuel cap it says its fine to use 98 and 95 fuels

I noticed a power difference between 95 and 98, and you wont get many k's out of the 95 tank

Thanks, so probably shouldnt even use normal regular 91 unleaded then?

No mate, certainly not....
The car will cope but you shouldn't be doing it.

Its confusing but 91 = 95 ron and 93 = 98 ron

My car is tuned to 93, which is 98ron

I have no idea why its like this, but someone might care to explain what the hell im talking about, cause i have no idea

US (as normal) measures everything differently to the US & Europe!

Thanks and I just thought 91, 95 and 98 meant the percentage of octane in the fuel ie

regular unleaded being 9% ethanol and 91% octane and so on for the others

Then what is 150ron fuel ?

Very expensive

Use 98 always. 95 on the rare ocassions you cant get 98 and 91 never. 100 octane is sweet too, you do find it sometimes

I reckon you go heaps further on 98 than on 95.

As mentioned previous I wouldn't use anything else besides as you could potentially damage your car in the long run.

I've only ever used 95 once when I had know other choice in Berry on my way back from a Kanga V & Macq Pass sprint. Other then that it's always been 98. Mostly Mobil and V-power, but Vortex is OK and a lil bit cheaper.

only used 98

found some 98 with 10% ethanol, was desperate... put in $5 until the next server came along

ethanol isnt bad for ur engine in small doses (higher doses require tuning for great fuel to air mix.)
ethanol actually cleans ur engine because of its low carbon content and it doesnt build anywhere as much carbon up in the engine as normal petrol... 10% is completly harmless if not helpful for ur engine
(correct me if im wrong)

Yeah not too sure, I just thought I'd stay clear of it to be on the safe side.
