ok so im goin on vacation n since nowaday we r all tryin to save some money in gas, i was wonderin if it was ok to run 91 in it every couple of fill ups, everytime i fill up in town i put 93 in no questions asked, so would it b ok?? also i heard that bp is ethonal free, is that true?? if its ethonal free,would it b better to run ethonal free or run with ethonal. ne thought please

 

your car is tuned specifically for 93 octane. i don't know if there is a huge difference between 91 and 93 octane. so i wouldn't go WOT too much. and BP has up to 10% ethanol. its fine to use

 

but like if im on the highway since im goin to ny as long as i dont WOT it 91 will b ok like every couple of fill ups?

 

yep no problem

 

It's al good because all I use is bp or shell I like that nitrogen **** lol. J/k it's all the same crap. Our cars are tuned for low octane and high meaning if the car see'z kr like alot in a certain amount of time it'll go into low octane. Te high octane I think is tuned for 91 because in the owners manual it says lowest grade u should go to is 91 which means to me it's tuned for 91. Just be careful to only get gas where u know they refill there tanks alot.....

 

ya i only fill up at either mobil chevron shell n hess sumtimes but i dont go to the lil ma n pa gas stations. aslong as i can fill up on 91 once in a while on this trip

 

I know its nice to save money on gas but, really if the price diffrence is like what 10 cents or 15 cents, thats like maybe a buck or two saved on a tank. but its your call buddy! just my opinon

 

you won't save much money
but you'll be alright

 

our cars pcm has different fuel tables just for situations like this. It has a high octane fuel table, and a low octane table. I learned this recently when I accidentally put 83 octane in my car. The pcm will recognize that a lower octane fuel is being used and knock back timing so you don't blow **** up. Hence why you will see significant horsepower reduction if you do so.

Would I make a habit of putting a lower octane in my tank? No. But it helps to know that our pcm compensates for stupidity.

 

well guys he is going on a road trip from south florida(we have 93 octane) up the east coast to NY. thats the reason for the change in octane

 

ohh ok gotcha lol

 

ya im goin from here to new england, n my parents n gf r comin, i always put 93 it n always will but i no they rather put sumthin a lil cheaper in. but as for goin lower i never do
