Fuel

Just to honor this thread... Yesterday was going on a all day demanding drive up mountains down mountains on some of the areas most demanding roads. 2000 plus feet elevation changes and over 500 curves in total. I have Driven nothing but 87 since my second tank of gas. But my last tank before this one I filled up 87 but also put in a bottle of tekron which is rated as one of the best fuel additives (same stuff as in pump gas) ran it out. Then with clean slate filled up with 93 pure non ethanol gas. Had a good 20 miles before the days hard driving for everything to adjust to the gas. Everyone asked me if any difference? Honestly no... I seriously can't see or feel any difference. I mean sure on paper there is a few hp or some other numbers but it's not enough to spend the extra money.

I still say just use good 87, then maybe once every 5k miles put in a bottle of top tier additive, Not cleaner but the stuff the gas companies sell bottled that is the same additives they put in the pump gas. And your wallet will thank you at the end of the year.

Yes that sounds like an awesome drive regardless of octane. If your running Top Tier 87 you probably do not need the Techron but since its cheap enough why not? You may also need more than one tank of 93 to actually feel anything. I'm still running 93 only since my car is basically a weekend cruiser. My wife spends more at Starbucks then I do on gas.

Is the price of 87 top tier vs non in your area the same price? In my area it varies from one price on one side of downtown to $.15 difference on another...same fuel. However almost every station next to another has the same priced fuel to a T even a top tier station vs the non top tier. So I figure just throw in the top tier since it's the same price.

Honestly though when I ran the Shell Nitro 93 it seemed like it lost MPG vs the Citgo 91 I now use but maybe it's my imagination. It should be the reverse. One day when bored I'm gonna reset the gauge and drive the same speed for the same miles to the other station reset the gauge and drive back.

On a side note just threw a coat of TW seal and shine on the entire car and wow does it shine. Gonna throw the Meguiars Ultimate wax on top tomorrow. Already has Jade ceramic underneath. Just thought I'd throw that in because man o man do I love that car. So purty

93 octane Shell, high compression motor needs higher octane gasoline. Also use BG 44k fuel treatment every 6 months in all my vehicles.

Yeah gas prices here are fairly the same across the board. No matter if top tier or not. Right now across town the prices are all 2.43 to 2.53 for 87. Now I don't know if the place I got my 93 from was "Top Tier" and from what I have read and researched "Top Tier" isn't about the gas it's about the additives in the gas. So The station I got it from is called quality plus its all they do is sell gas and I think they are nationwide not sure. But they are the only people in town sell pure gas and at regular prices not marked up. Their gas is fresh because they typically have lines all day at the pumps. So not knowing who they get their gas from is why I chose to experiment and put my own top tier in it LOL. Technically I made my own gas top tier since top tier is about the additives

They'd have a sticker on the pump if its top tier. I'm no expert either still doing tons of research and learning. Here's the sticker for top tier(not all top tier stations have their pumps marked).

Well did some research and the stations I get non ethanol fuel from are local to North Carolina and buy their gas from shell. Interesting because they are anywhere from 10 to sometimes 30 cents a gallon cheaper then shell. hummmm well I guess I use shell gas too them LOL

Just because your stations source their fuel from Shell it doesn't mean it is the same as the gas sold at Shell stations. It may or may not have the same detergent package as they may keep this gas for themselves. Also adding 12oz of Techron every 3k miles is not the same as the detergents that you get every time you fill up. It is not a substitute. As always do what you want but on a regular basis I would recommend making sure your gas is Top Tier. If you want to Techron, go right ahead, it will not hurt.

Yeah...after all the research I've done and engineers I've talked to on a few different forums they all recommend top tier. So that's what I've been doing. I used to think fueling up all my vehicles and equipment at the newest station with the newest tanks meant I was getting the best gas. I was wrong.

The Coyote although high compression does not "need" 91/93. It may want it if you are doing constant high RPM WOT pulls. If you are please go ahead and put in 91/93. For everyday driving, Ford recommends 87. It will do no harm. I've never read about a blown engine (NA) on here due to gas octane.

What's funny that with all this talk about gas most of us will not own their car long enough for it to make any difference. Our cars can go over 100K with little maintenance. We're just a bunch of car guys who over obsess about everything. Not that there is anything wrong with that.

You're exactly right...likely trade my baby for a GT500 but hoping they come out with one last KR model. I've made up my mind. Its GT500 or bust with Hope's of a KR model release

No...they don't have to have a sticker. Like you mentioned all shell stations are top tier as well as many many others like Phillip's 66 etc...

Yeah but that system is iffy. I dont think they have to be stickered. according to the top tier web site ALL shell and listed stations are top tier. And I figure if I buy from a local station that buys their gas from shell then well its all good.

Right now across town the prices are all 2.43 to 2.53 for 87.

Lucky you. That's about CDN$0.87 per litre for 87. When I was out and about last night, I saw prices in and around CDN$1.15 per litre. In round figures that's about 25% cheaper. The other thing I have to watch is the differential between the 87 price and 91. I know in many areas of the US the stations have the price of all grades on the pylon sign. Here we only show the price for 87. The typical price difference to 91 at the Mobil station I usually use is around $0.18 but I have pulled into other stations showing a cheap price for 87 with $0.25-0.27 extra for 91. I think they figure if you've pulled in and gotten out of the car you'll fill up anyway. So now I pull past the first pump slowly and look at the pump prices and if the difference is too much, I just pull out and don't fuel.

My wife spends more at Starbucks then I do on gas.

I buy Shell 93 and Starbucks.

I need rethink my spending habits....

Gas prices are so strange. I guess we pay less for 87 here in south east cause we get stuck on 93. I have seen lots people post "well 87 to 93/91 isn't that much so why not" But here its as much as a dollar difference 97 to 93. Its a 16 dollar per tank difference and why I am so typically against premium. Here anyway it's just not worth the price difference for the little bit, if any, of performance difference. It's Not uncommon to see 87 at 2.20 to 2.35 a gallon here. And with a loyalty card I also get 10 cents a gallon off every fill up.

Just checked Gas Buddy as I need to fill up today. Costco is $2.16 for 87 and $2.69 for 93 (both top tier). So $0.53 a gallon difference. I’ll probably take around 13 gallons so an additional $6-7 dollars. So four Costco hot dogs.

I only fill up a couple of times a month so what do I do? I’ve never put anything but 91/93 in either of my Mustang’s. I’m not about to change today!!

wel there are plenty of websites and forums explaining what you are talkign about and they all say the same thing. using fuel lower than that what is required will cause knock and cause the system to over compensate. but the one fact EVERYONE elects to ignore is the owner's manual with a big old stamp says design for 87. These same sites will also tell you that using octane ratings over the required...NOT recommended but required is a WASTE of money. I find it interesting the power of popular perceptions. There is literally thousands of websites telling you gas is all the same for everywhere from every manufacturer in fact most gas is held in comunal tanks before delivery to separate vendors. yet peopel will swear there are differences in gas by maker. Only differences are additives the gas itself is all exactly the same quality. There is also an equal amount of studies, website, forums all saying engines made to run 87 get zero benefit form running higher octane fuels yet people swear that is also not true. The whole top tier fuel and recommended fuels thing is all marketing backed by gas companies and auto makers in bed together. If you look at a list of top tier fuel sellers it's basically them all. believe what ya want I'm not really arguing with you. I am just passionate about people not wasting money as these companies already get enough of our hard earned money. Matter of fact it only takes a quick google search of is premium any better and you would be hard pressed to find a website that says yes... so not sure why people still hang on to this idea. The info is out there and not exactly hard to find. Now info supporting its better is actually hard to find. 91/93 is for cars that require it like high compression force induction cars. But big v8 NA cars don't need or benefit form it in stock form. But again not here arguing and I swear I just like to see people keep their money on things that simply aren't worth it or do nothing.

So what is the threshold for high compression? I would say a Mustang GT with Gen 3 Coyote which has 12:1 compression is a high compression engine and does benefit from the higher octane gasoline
