Hi everyone,...... First, let me say how in-lightning ( pun intended) this site has been to me. The vast, real world knowledge base is truly staggering, if one takes the time to look. I live in Ca. and, as you know, our gas octane is limited to 91. Having installed a superchip (Ca. collectively ) we don't enjoy the full performance gaines, noteing that 91 seems to be the cut-off point, relitively speeking, in all the threads iv'e read. Long story short. I was searching the web for a high test fuel outlet near by (fat chance) and I came across this guys page, it's a little long, but I think the L crowd will be most interested. I KNOW, I KNOW, the evils of additives, I read that too, but it's YOU as a forum I post my 1st thread, toss it around,could be an option.

Hi HP,

Actually, you *do* get the same performance gains from the Superchip that all other states do just by using Chevron's 91 octane, as they are still supplying as much as 93 octane to the pump. If you do not have access to Chevron, then try to stick with Texaco or Amoco.

Just thought I'd let you know............

Good luck!

 

Hi Mike, Thanks for the response, but your statement above suggests
Chevron is actually supplying the 93 octane to the pumps marked 91 in the
state of Ca.. Now , I know the MINIMUM can be no LESS than 91, and I
would be surprised if it went any higher than 91.8 , on a good day in the
summer, let alone mid winter. But let me qualify that statement by saying that
my knowledge of fuel is limited, and if Chevron is giving me 93 octane for
the price of 91, then I feel bad, cause I didn’t get THEM ANYTHING for
Xmas.


Ps. good to see you back, and I'm sorry about your loss.
best wishe , Dan.....

 

Hi Dan,

Thanks for your kind response and your humor!

You're right in that the octane sticker is the minimum guaranteed octane, and most oil companies aren't giving anything away, of course we all know that. It's a matter of how many different formulations they have to make, and sometimes it's just more economically feasible for them to supply a bit more octane if that means they don't have to make any changes. That's how it's been explained to me by some people in the business, and I'm certainly no oil company expert. We do our best to informally stay abreast of relative fuel quality in many areas of the country, as it affects performance & tuning of course. What we've found in California is that the Chevron "91" octane is a very good fuel, and we're not having to retune anyone who is using it, people who got their Superchips when you could get 92 & 93 octane at the pump.

Other fuels are not giving the kinds of results that Chevron is in that area, which is why we make that specific recommendation. I don't know if we can say that you're always going to get a solid 93 octane all the time from Chevron out there, but we do hear that a lot, and we've got a number of high-boost Lightnings running very aggressive programs out there. Not quite as aggressive as we can run here in the East, but pretty close. All in all, Chevron is currently doing the best job out there with our California customers.

Happy New Year!

 

Thanks Mike, you can understand my confusion, It says 91, but it's not, or it could be. But if it's not, that's better, RIGHT ! Happy New Year to you and yours, Dan.......

 

Hi Dan,

Sure, it's easy to be confused on this, especially knowing that nothing comes free. Just a little luck working on our side for a change, perhaps!

 

HPsteem,

I just want to add a heads up to the people who might try using Toluene as an additive. It is very flammable and the vapors are harmful. We all should know that.

Now the important stuff: Use a filter to trap the sedament in the can before pouring into the truck's tank. I am trying some combinations and I pore the can into a jerry can using a funnel with a paper coffee filter to trap all the crap. It seems the paint stores are not too concerned about it, after all when painters use the stuff they filter their paint.

Hi JMC,

Good point!

Toluene is present in pump premium gasoline in large quantities already, over 40% by volume in most cases! It is a primary octane-enhancing ingredient, and thus why people try to use it sometimes to raise octane. I find for many reasons, you're better off just using a 98 or higher octane unleaded racing gasoline from the pump at your local drag strip, or from other fuel suppliers, etc., so you get a proper fuel formulation.

You have to be very careful pouring in toluene, just dumping more and more toluene in the tank can make the motor lay down, in addition to all the health risks & other aspects you mentioned.

I'm not a fan of mixing my own fuel, and since I'm not running a funny car or AA/ dragster (menaing, a nitro-bunring motor), I prefer to let the oil companies do my fuel formulating.
