Toyota Gasoline?, Preference Options

[JoKeRkId613]

I'm about to supercharge my car and know that I will be using premium grade fuel. Is there any Toyota-preferred gasoline company? I did a search and it seems Ferrari recommends Shell. I'm no Ferrari, but I usually fill up at BP (Amoco). I remember seeing a list a while back with a few gas companies that are better for Toyota engines because of something in the gas. Does anyone have that? or does anyone if there is a recommended company by Toyota?

I know this won't make a noticeable difference, but figured since gas prices are pretty mcuh the same around town I might as well fill up at the best place.

Thanks.

Shell is the best quality gasoline there is period.
The detergent and addative aspects are better than others

shell > all

[LewFX]

its no longer shell, they got bought out by americagas

[Valo666]

i use shell and sunoco all the time. I seriously wont fill up at any where but. Even if Im gonna run out of gas, i will push my car to find a station. Ive only filled up at 1 other type of station once in 2 years because i was in the midel of no where and ran out of gas.

[lagos]

gas is gas. brand names are just clever marketing to get you to think there is something magical in that tank of gas you just overpaid for.

[LewFX]

i use chevron, its on toyotas recommended list

[playr158]

gas isn't gas....I'm accquantences with a very experienced, rider, racer and employee of BG. Very Very knowledgable man, they are different...

but AMEN for overpriced....wtf $3.19 a gallon....thank god for 3.5 gallon tank!

the top three companies with the best addatives are:
SHELL/CHEVRON

must be nice. lol.^

so shell it is.

edit: anyone know if shell is on the list?

its like motor oil and oil filters. youll always see people swear by one or another based on brand name and marketing, not really based on what they are really buying.

i was just watching a commercial on tv about how shell gas would reduce gunk built up. they showed the top of a valve covered in oil sludge. anyone who knows a thing or two about cars would be able to tell you that something like that has more to do with oil then it does with gas. or there is a commercial for quaker state motor oil that will help you unlock all 300 "horses" from your sti. its all bull**** marketing.

[Valo666]

My imput shouldnt count though, cuz gas here is different than gas in the states. We have different additives, and also we are only legaly allowed to have a certain octane rating to be sold as daily fuel. If you wanna get any thing over 100 octane you have to buy special race fuel from a race fuel supplier. Like just regular 100 octane gas, or C12 has to be bought some a liscence dealer. Theres apparently some subtil differences between our gas and the US gas.

That sludge build up is because of oil and gas mixing and the oil breaking down. So it does have something to do with gas, if you have crappy internals. Also oil can free up HP if you use the right formula for the weather and operating conditions. Also some oils like royal purple have been tested and show HP improvments..not majour..like 5 or 6HP on a Z06, but nothing majour.

[Bitter]

top tier fuel isnt all bull. some fuels really do have manufacturer recommended amounts of additives while others really do not!

i'll tell you one thing tho, you can tell alot about fuels and oils by running them in a 2 stroke. penzoil 2 stroke oil and some random brand 93 octane made some HARD deposits which built up FAST. mobil1 2T and shell 93 left almost no deposits and what was left is very soft and easy to clean.

go put your car on a dyno. youll see + or - 6hp just between runs without changing anything.

the engine would have to have very bad compression for gas to ever mix with the oil. and if thats the case, engine oil sludge would be the least of someones problems.

a little gas always mixes with your oil, but most of it vaporizes again and is burnt (what the PCV does).

[GTS13]

I try to only use Shell.
Gas is not gas when places like Arco add water to it.

[Kwanza26]

Hehehe... you guys sure buy into "gimmicks" pretty easily. Granted the fuels are slightly different due to processing differences and additives, but it's not gonna matter to the engine unless it has something to do with octane. Even still, higher octane only makes the fuel more resistant to pre detonation. It has nothing to do with power really... and the ONLY cars that REQUIRE high octane fuel are those with higher compression... say 10:5 or higher... or if they're heavily boosted and generate a LOT more heat...

Cheap fuel ftw!

Do you really believe what you are saying? Octane has a lot to do with power even if it's just to keep the ECU from pulling back timing. Also diff gas manufacturers use diff additives which does have an effect on deposits and such. Are you actually saying you can't feel a difference between Stop And Go or Grocery store gas and say Chevron or Exxon? There isn't that much difference between the major comanies though.
Just because you haven't paid that much attention doesn't mean there isn't a difference or it's a "gimmick". And isn't your car turbo?
We could go back and forth about this all day but I swear by Chevron and Exxon and I've actually had a mechanic years ago ask me if I ran Chevron gas all the time and he was right. He said I had some of the cleanest used valves he had ever seen. Plus I can feel a difference on the butt dyno and I'm pretty sure I've seen studies on it before using a real dyno. may not be huge differences but they are differences you can feel and that's enough for me.
BTW - I work in the gas refining industry also. Not that that makes me an expert or anything.

Did you READ what I wrote? Additives and such are just gimmicks... All of that crap they feed you about "reducing deposits" and such are all just gimmicks. Why? ALL fuels do the same thing. There is no "cleaning" element to fuel because it's already mixed with air and in a split second, already vaporized and burned. The reason for deposits and such form is almost always because of dirty PCV systems. As for octane... learn what octane does to an engine before you claim it can affect power. LOL. Octane just makes fuel more resistant to pre detonation. That has NOTHING to do with how an engine makes power. It however... alleviates a negative side-effect of tuning. In other words... octane itself doesn't "improve" performance... but because it makes fuel more resistant, the engine can in turn be tuned more agressively. Higher compression, more agressive fuel maps, more agressive ignition curves... things that typically generate more heat.

FYI 6gc GT's are 9:5 compression. A FAR cry from 10:5. If you wanna discuss this... know your facts. You can swear by whatever you want... but seriously... fuel is fuel. Like I said previously, additives are just gimmicks. They do not adversely affect the way an engine works etc. Octane can potentially affect an engine's performance based on the tune... BUT... will do NOTHING for a stock motor that isn't designed to run on higher octane fuel.

[Bitter]

lol additives are not gimmicks at all, but buy the cheapest non branded grocery store gas you can get and then after a couple years have your injectors flow tested and take a look at your piston tops.

[Kwanza26]

Maybe if you guys made an argument about "WHAT" additives do and "HOW" they can affect performance... then the discussion can go on. So far... it's like trying to convince Christians that God in fact did NOT create humans (*GASP*). People can believe whatever they want... but at least have a good reason. "Dirty engines" as you're trying to argue here is almost always caused by the PCV system... you know... excess oil and pressure bleeds off into the intake... which combines with the air/fuel mixture and gets burned. Yeah...

"Will you take the Red pill?.....or the Blue pill?"
"Which one is the placebo?"
"The red pill."
"Fork it over."
"/sigh"

[dagreat1]

so which octain should we be using?

[Insanity-74]

Petrol octane ratings and additives, This is is a hugely complicated subject.....Octain rating...this is the petrols ability to resist pre detonation, where the heat of the engine components ignites the petrol before the spark plug does. This can decrease the power of a car because if the petrol ignites before the piston reaches the top of its compression stroke, then the engine is fighting against the detonation of the petrol/increased pressures = reduced power, broken pistons etc etc, So Octain rating can/does improve power.

Petrol companies use different methods to produce the "Octaine rating" in petrol.....Shell does this in there V-Power by making a higher grade of fuel, ie there 99ron petrol is produced as 99ron petrol.

Companies like Greenergie which also makes a 99ron petrol use a different method, they get fuel from either themselves at 95ron or buy it from any other compay at 95ron and add aditives to increase the ron rating synthetically.

Obviously the Shell petrol should be better being origionally designed as a 99ron fuel, but most companies add detergents etc to the fuel to help clean the engine etc...this does nothing to improve power, but can improve overall performance by maintaining the engines internal workiing parts, keeping them cleaner etc.

If you look in Evo mag from late last year they did a fuel comparison.

BP`s 98ron Ultimate came top in both HP gains and torque gains over regular 95 ron petrol. Greenergies 99ron came second and Shells 98 ron came third so I guess its whatever petrol suits your car....Petrol isnt just petrol though there are many differences caused by production techniques, types and percentage of addatives ron ratings etc etc

Now we get 99ron shell and 102 ron BP ultimate plus both of which give a noticable increase in performance over regular 95 ron petrol.

Normal engines (non turbo) do not produce much heat so dont need the pre det resistant properties of high Octain fuel, so you wont need to run anything beyond 95ron...turbo cars should run 98 ron or higher unless mapped to run on the lower grades of petrol.

Note - Petrol in the states is produced usually at a higher grade than elsewhere, also the grade is rated in a different way...RON......PON etc

[Steevo]

http://en.wikipedia.org/wiki/Octane_rating




The detergents are more for the FUEL system than for the intake system. And the fuel is not fully evaporated or intermixed by the time it reaches the back side of the intake valve, partially allowing a 'wash' of the valve. As a fact you can check with engine manufacturers and the direction of swirl on test engine scan be determined by what side of the bore is worn more, the un evaporated fuel hits the side and washes the oil off partially causing slightly accelerated wear.



But to be honest, unless you NEED the extra octane, it is a waste to use higher octane fuel.


But it does seem to me as well that shell has a better formulation than other brands, based on personal experiance, and many trips to see my parents 1,600 miles away. Both in fuel mileage and in performance "feel".

hows wawa gas stand on the list?
x2 on shell is best.

[Jeremiah]

Anyone have any real evidence, or is this all just opinions and conjecture? If shell / chevron fuel is REALLY that much better, how come evidence of it is so weak?

And, Kwanza26 is correct about the octane thing. Unless you have an engine that REQUIRES more pre-detonation resistant fuel (over-sensitive knock sensors, high compression, forced induction etc), it won't make you go any faster.

[GTS13]

True, it's not going to make you go any faster. My only complaint is the cleanliness of said companies, so I prefer Shell due to the perceived quality of the gasoline over others.

Took a tip when my lawn mower starting dying regularly and when serviced they asked what kind of gas I was using. Turns out multiple people were having theirs serviced as well due to Arco gas being used. Switched to Shell and never had a problem with it again.

Oh and uhh, Air Five all the way from Washington! Shell kicks ass!

I filled up with gas from QT and my check engine light came on lol.

NEVER AGAIN.

I thought it was the additives adjusting cuz it went off after a while.

And in my opinion, different companies do affect the car diffferently..

My brother put walmart gas in my car (i ought to kill him) and my car had a rough idle until i ran out of gas and filled upwith another company. And when i did fill up with was with shell....I noticed a power difference with acceleration and when i'm at 4000 RPM and the 2nd came kicks in.

I notice the difference and i do believe discounted and cheap gas don't have a short term effect (such as filling up once and MAYBE twice). If you use it all the time, i reccommend fuel injector cleaner and etc. etc. Because it does affect your car.

I use shell all the time. If not its chevron, and sometimes BP.

now.. tell me this.. doesn't any one here LOVE the feel of fresh gas in your car?!? I love it! The acceleration is amazing ).

[GTS13]

Yeah I noticed the same thing with my Camry. I let my friends mom borrow it and she had filled it up after using it. When I drove it I noticed that it just didn't feel the same, until I filled it up again with Shell and it accelerated my better. Not to talk up Shell but more so talk down about the gas she put in.

[Negative]

All these people with the same experiences yet people will still get on here and laugh because they think we are falling for "gimmicks". WTF ever.

[Kwanza26]

*sigh*

People let this sh!t die unless you have something productive to add. Gas is gas (minus octane ratings of course)... additives is what makes the gas different... but do they affect performance? NO! The additives are specifically designed to maintain the fuel system, ie: less fuel filter clogs, etc... but that does NOT affect how the engine burns the gas. Shell is NOT a miracle fuel that makes a car significantly better. That's just ignorant. GAS is GAS. If your car has trouble from pumping some cheap indy fuel... well... it's either placebo or your car has problems.

Something you all might want to know... indy gas stations across the united states buy whatever is cheapest. One week they might have Shell, one week exxon, one week BP. The tankers all get their fuels from the same refineries, it's just after they buy it, they put in their own stuff.

In the end... if you wanna fork over more cash to keep the rich pigs happy... be my guest. Just don't preach cluelessness.

Do you really think people here are an accurate sample of the general population? People here are enthusiasts who are willing to spend for performance. If that alone doesn't tell you something... then sorry you just don't get the fact that you've been bought by a gimmick. Kinda like Starbucks coffee is magically better so it's OK to spend twice as much... yet Consumer Reports's blind taste tests show consumers picking McDonalds' "cheap" coffee over Starbucks. Heheh... yeah. In the end... it's your money... do as you will. If these other "cheap fuels" were that bad... why/how are they even still competing?

I find it hilarious that you get so upset over it. While their may be no difference in the fuels, you sir are still defending what you prefer to use just as the rest of us do. Your preference just happens to be the cheapest; so while we preach ours your just as guilty for preaching yours.

[lagos]

gas is gas. the only thing i would worry about with cheap shady looking stations is that they might have 87 in their tanks but lable it as 93 to try to make a profit. but that wouldnt matter much for most na celica owners. the car was factory tuned and designed to run on 87 octane.

[Hanyo]

I admit it. I'm a fuel sucker.

I've dont mpg test on my own and deterimined that shell gas give more MPG then arco... ect.

This and I have a shell card, so i get a slight discount on gas.

However, i do not believe the advertising strategy of gasoline cleaning my fuel system.

[Sinyk]

Esso

Their points are exchangeable with visa points so I can rack em up faster That's my only reason (and it's on the way home from work)

87 octane here. Gas prices are high enough, I don't need to pay more for my daily commute to work. You won't find me drag racing around town anytime soon.
