Ive been running 93 octane in my sr for about 4-5 tanks now. Is that good for the engine?

u can and should only use premium gas in an sr to prevent knocking n pinging. i live in ga and all we have is 93 oct for premium. there are no harms whatsoever to your motor.

93 is hard for me to find, my car is tuned on 92 and runs great

The 180 and silvia can run on 91 stock. Anything higher is better

 

[driver11324]

alright thanks, 93 smells the best anyway:rotflmao

last time i tried to buy 100 the nozzle was too big to fit in my gas tank (that's what she said... oh!)

 

[gtp420]

Are you sure that wasnt diesel. lol

 

[S13Point5]

they put bigger nozzles on the higher octane/race gas so people dont put them in your car directly,...atleast around here thats what they do,...i always put it in a portable gas tank and then put it in my car

 

[gtp420]

Ya thats what your suposed to do. Its illegal to pump it straight into a car.

Thats what I was gonna say, same by me.

this may be a dumb question but why? more combustable?

I figured they had a problem with people pumping $100 worth of gas by mistake thinking they had the 93 nozzle.

 

[gtp420]

Ya its for saftey. Thats y the pump is far way from the other ones.

 

[ladiesman8527]

not around here...we have 93 right at the pump with 89 and 91.

F.Y.I.

Higher the octane number, the more it resists burning. AKA less combustable AKA harder to burn. :thumbsup

well see thats what my understanding was but then someone mentioned it being a risk to pump straight into the tank and i didnt know why. then i thot my understanding was backwards. but here where i live they have 93 right at the pump with 89 and 91. i pump it right into my tank, and so does everyone else. i had no idea it was illegal and the nozzles on our pumps arent oversized.

93 is not considered "race gas",,...i pump 94 at sunoco in my 240,....the 100 octane and higher pumps are the ones with oversized nozzles

 

[ladiesman8527]

maybe where u live, but not here....every gas station ive gone too in TN, if u pull the 89 nozzle out, and the 93 nozzle out, there i dentical, and both nozzles fit. thats why i was confused. but i dont think ive ever seen 100+ at any gas station around here. maybe TN is just wierd.

he was saying that the 100 oct nozzle was oversized not the 93 oct nozzle.
