87 octane for me, QuikTrip gas \m/

 

91 octane from chevron...or else I ping. I tried 76's 91 octane but my engine didn't sound too good. And I won't support mobil gas because they rip you off, no matter where they are located.

 

So despite published scientific articles that state over and over again that "high performance" gasoline is just hype for engines that do not require it, you are going to give this advice?

Am I missing something?

 

88 cuz I feel better not using 85!

 

why not buy octain booster for the difference? personally i run 87 and no problems, premium or regular, it's the same, just less $$in my wallet for premium

 

you may get some ping at lower loaded rpm. when i notice pinging i move the octane up. when the temperature outside falls, i lower the octane until i hear pinging. generally i run 85 in the winter and 91 in the summer. (for you low-altitude people that's equivalent to 87 and 93 respectively).

i think it should be easier to start with lower octane. octane is the measure of resistance to burning. so higher octane fuel is less volitile and so it's harder to vaporize. this can make cold (that is winter temperatures) starts harder because the fuel can't get vaporized. that's why it's usually advisable to run lower octane in the winter.

 

Just going form my experiences. If they are different the anybody's studies, they are willing to contest me.

Ps: A scientist would be classified as anybody with a Bachelor of Science (BS as I prefer)......
Therefore, this could be some person that took 2 years of university, tried the same test as I, with a different vehicle, and noticed no results.
There are many variables as to what will effect a motors performance (any mix of the following: Temperature, oil's grade, motor's condition, modifications etc. etc.). It's just like people that are allergic to peanut butter, animals, etc.

Sorry, I don't mean to come across as an a-hole, it's not intended.

 

Regular unleaded here. No need for more either.

 

I'm glad I don't know what pinging is or sounds like.

Nothing to worry about, at least not at this particular moment.

 

190 hp pick up truck.....guess what octane I run....I'd run higher if I ever heard any ping....but since I havent I wont....

I ran 93 once and the MPG were worse, but I only ran 1 tank so my calc. may not be very acturate....

 

I run 89 oct. Seems to be smoother with the mid grade.

 

87, my truck doesnt need more, and gas is expensive... $2.31 today

 

87. Why?? Try $2.65 per gallon.

 

damn maui is expensive. I wonder how much they are paying on Lanai. Im guessing almost $3.00

 

here in wv 87 = $195 89= $205 93=$215 I remember a few years ago when I was paying 95 cents a gallon for Sheetz regular! WTF happened... I would like to personally thank a few people in Washington DC but wont mention any names... :cry: :cry:

 

i remember sheetz! i use to live near altoona, the headquarters for sheetz. now that i live in colorado i really miss sheetz. there's nothing like filling up your tank and then getting an MTO!

 

Here is my experience, 2003 v8:
I run 87 octane most of the time but I will run the 93 from time to time. When I run the higher octane this is what I notice: Fewer downshifts when encountering hills, especially when towing. I also notice slightly better gas mileage. Not sure why? But the downshifting, or lack of downshifting, is consistant (same hill, same speed, same conditions). Running the higher octane seems like the engine does not have to work as hard.

 

I said I would never put 87 in my truck, but since 87 is now $2.21 that's all my truck drinks.
However, I can tell the difference between the three grades. The truck is deffenatly more punchy with the higher grades of gas. But whatever, it's not like i go around stomping the gas.
One more thing. with 92 the truck doesn't seem to run as smooth.

 

I run 89 in mine, it will ping on 87 when I try to pass or on uphills. 93 is a waste of money for most.

 

ok yota has given me the courage to run 87.
