Similar to many it seems, I run 87 as well and it seems to do just fine. I am definitely more interested in seeing if I notice any differences between brands now, but for better or worse, cheapest is almost always going to win for me.

 

E85, 87, 89, 91 and 100 oct. race fuel out here in Nevada
I mix it up every once in awhile. run 87 Acro crap gas on long hauls or when i know im going to wheel and just burn up gas, then chevron 91oct. to clean her up, or 100oct but runs rich fuel but cleans up carbon & boy does it make great power. and normal get gas anywhere but shell 89oct when she tows or reg DD.

 

Thats interesting,whys that? here in the UK alot of our service stations now stock LPG,its half the price per litre than unleaded.my truck runs great on it and was converted from new at the dealership.

 

I use 93 oct in all of my vehicles. it produces better mileage and is simply higher quality fuel. I don't even run 87 oct in my lawn mower.

 

That is a good site for information. I think Sunoco might be on it too.

It's crazy how much more premium fuel is here in Canada then in the US. I live 15 minutes from Buffalo,NY and premium is only 20 cents a gallon more than regular. In Canada, it's usually 10-15 cents per litre more (that's like 40 cents per gallon). Another rip-off from lack of competition.
Another rip off is advertising gas mileage as 34 mpg when the g is a Canadian gallon (4.545L) versus a US gallon at 3.78 L. So my '87 Cherokee would get 18 mpg in the US but miraculously it would also get close to 22 mpg in Canada.

 

Yup, I use seafom every once in a while. Believe it or not, I don't ever get much smoke out of it after running half a can through the intake. I'm poor and run what's cheapest. Now, if I start having a problem with the gas, I will change stations for a while.

 

Hard to say about Sunoco since they purchased Petro-Canada. Apparently some of the fuels are the same now, but there are still station-to-station differences (such as 94 octane)

 

I recommend shell, 76/philips, chevron etc. The better quality fuels are better and usually see improvement. 76 fuel is from the same plant as shell but shell is slightly better, both are good tho.

 

Well those were some interesting answers. Thanks everybody. Next time I fill up I just might try 91 to see if I get better milage. Not that it will matter because Ill probably stick with the lower cost fuels but I'll try it!

 

What does gas cost where ya'll live. Here in WY its about $3.55 a gallon

 

Many states have laws against taking LPG gas into tunnels and on certain roadways. The valves must be shut off, at least.

The concern seems to be about possible leaking tanks and valves. LPG is heavier than air. They appear to be worried about possible explosions.

Aside from bulk propane distributors and some RV campgrounds and service centers, LPG is not well supported here.

Its main use is as a heating source for furnaces in rural areas that are not served by natural gas pipelines.

 

lol, so brand whoring never stops does it? here in the states, im not sure about you silly canuks, our fuel is federally regulated, so while you think you are getting something different, you arent. it is all the same! if you really think that you are paying more for a better product, you are a fool! while their companies have flashy names for additives, understand that the next gas station has the same stuff just with a different name! so if you go to chevron vs arco, you are paying extra for that fuzzy feeling of lining someones pockets. the only thing you can do is make sure you get gas from a station that is always moving fuel to make sure its fresh.

 

Ah, yes, yelling on the Internet makes you so convincing! Yes, the actual gasoline is regulated, but the additives themselves are not.

Why don't we look at some actual facts?

I run 87 with the monthly treatment of 91. Fuel around here ranges from 3.89 in town with it being 3.65 by the interstate 8 minutes outside of town. I get 22 mpg out of my comanche, 18 mpg out of the Cherokee. With them both being renixs they seem to run better on 91. Haven't paid attention to mpg changes. Haven't tried shell gas around here. I stay away from chevron. The one time I tried there gas I got 13 mpg in my cherokee. I never saw a tank of gas go so fast. The jeeps seem to like bp fuels. Haven't even bothered trying e85 since there's none around here. Only diesel stations in town are the chevrons.

 

Yeah, a lot of those laws go back to the 70's and 80's when LPG conversions were more common. Plenty of us got the carb spacer plates and rolled our own. Unfortunately some of the conversion jobs were kinda scary, leading to some restrictions. I had a car wash rip the regulator and safety valve off my bed-mounted tank in a GMC pickup. It's a shorts-changing moment, praying that nothing sparks before you get to the tank shutoff.
