I just got one and I love it!! it's soo roomy, it's tornado red and DSG auto. I'm so excited, I wanna drive all the time. What kind of gas do you guys use?
This is not correct. Your car will run on any grade of unleaded fuel. Your car is set up to perform the best using 91 octane (stock). If you use a higher octane you will reep absolutely no benefit unless you alter the compression to handle the additional octane. Using a lower octane fuel will not harm your engine, not on the Mk5 anyway. However, you will notice a decrease in performance when you are really pushing it.06TRMKV said:Its gotta be 91 or 93 octane. its the only thing your Fast will like everything else will cause problems down the line.
I was correcting MicMoor77, Thalo. Thanks for your pointless post.Thalo said:Next contestant - UnitedGray from Delaware, special subject the bleedin' obvious.
Where do you see that the Mk5 is meant to run on 93 octane? I am looking inside my fuel door and it recommends 91 octane [(r+m)/2]. Also, the added octane won't benefit you unless your engine is tuned to use it. Octane is what prevents your fuel from spontaneous combusting at lower compression ratios. Tuning your engine will typically result in a higher compression ratio, therefore requiring a higher octane fuel. Without this tuning, you are just wasting your money.UnitedGrayGTi06 said:93 octane is the best, not 91. Your car will perform better and be more efficient on 93. That is what is is meant to run on.
If you're referring to what is written inside your fuel door then the number 95 is for the euro customers where the fuel is graded by RON only.GranTurismoInjection said:I thought it said that you can use 95 at the highest, and 91 at the lowest (although we all know u can go lower with no problems).
