Greetings: The Toyota dealer customer service rep (the person who show you the how to operate the car, warranty, go over some document etc at delivery time) told me that it is recommended to use Regular unleaded; however, the owner manual recommend Premium unleaded. So who is right? Personally, I always use Premium for my Camry and Altima. So I don't know if there will be any difference for an SUV. My driving type is mostly highway and local, no off-road or towing. Your insight thought or additional comment is greatly appreciated. 11-04-2003, 09:30 AMBanned iTrader: (-1)

Octane was a poll last week and here is the link: https://www.yotatech.com/forums/show...light=gasoline You might try the "flashing green button of death" above to find more helpful information regarding fuel octane levels. From an engineering standpoint, I think it is all a scam to make people pay more money for gas that really does few engines any good. To increase the performance and eficiency of an ordinary engine there really isn't a whole lot of lattitude with the octane level, not enough to make a significant difference. The only way to significantly increase performance and efficiency levels for ordinary gasoline engines would be to add lead again, but that ain't going to happen for obvious reasons. I just burn plain old 87 octane. I have got to have gas, so I just swipe the credit card, fill it up, and go about my way and pay the bill at the end of the month. I couldn't even tell you what I paid for gas the last time I bought it. My 0.02

Im guessing you got a 03/04 4Runner, V6 or V8 does not really matter cause they both use regular 87 octane, reread your owners manual cause it does not recommend Premium, it recommends regular 87 and for added performance Premium can be used. I've used both and since I drive with a lead foot I only noticed my gas consumption increase with premium, with regular it runs the same and does better MPG wise. Please amuse me and tell me you have both a V6 Camry and a V6 Altima cause if your running Premium in to 4bangers I need an explaination why, I know on Altimas.net the V6 guys are big on premium but 4bangers run regular, the compression ratio is like 8, 10 and above need premium 11-04-2003, 10:26 PMRegistered User

If I know I'm going to be towing, I'll fill up with 89 or 91 ahead of time. I tend to notice a very minor performance increase with the higher octane, but that could either be a real "seat-of-the-pants" sensation or just in my head. 11-05-2003, 10:11 AMContributing Member

Despite what everyone says, the 93 gives me better pep getting on the highway and better gas mileage. I calculate the gas mileage every week. I average about 16 mpg city/hwy all week. On straight highway shots at 80 mphI'll pull 18-19 mpg. Pretty amazing for the V8! I used the 87 octane for a couple weeks and I pulled a little over 15 mpg during a normal week. So for me, the 93 works. Plus, it's only $1.61 here locally. Much cheaper than other parts of the country. 11-05-2003, 04:07 PMRegistered User

Toyota's HP and torque ratings are based upon premium unleaded fuel and the engine compensates for lower octane by retarding the timing and changing the cam timing maps, producing slightly less HP than when on premium. There is an engineering handbook on the V6 engine that shows the HP and torque outputs at various levels of octane and the related changes to the VVTi map and the timing map. My dealer has it but indicated it is not available for purchase (it would take an engineer to understand the thing anyway which leaves me out). Toyota, like all manufacturers, wants to be able to advertise absolute maximum HP and apparently the V6 with its sophisticated valve timing responds better than most autos to the octane differences. Personally, I notice no difference whatsoever unless I'm towing about 2200lbs and then it will downshift less often on premium and gets slightly better gas mileage (<1mpg difference). With a 15% price differential for regular versus premium, it isn't even close to worth it, IMHO. 11-05-2003, 04:12 PM

Join Date: Sep 2003 Location: Parrish, FL Posts: 139 Likes: 0 Received 1 Like on 1 Post I run 87 at all times. Even when I'm towing with my 3.4 liter. A higher octane rating does not give you more power. In contrast it loses power because when it burns, the combustion isn't as efficient. On newer vehicles there will be a felt increase in power because the the computer will advance the timing. So unless your vehicle requires premium you are wasting money.

Join Date: Nov 2003 Location: Denver, CO, US Posts: 1,434 Likes: 0 Received 1 Like on 1 Post Does 4Runner need premium fuel?The best gas to run in your 4runner is whatever your owner's manual recommends. If your specific model calls for premium, that will be the best performing fuel for it. Most 4runners can safely run 87 octane though – they just won't make as much power or be as fuel-efficient.
Can I put 89 gas in my 4Runner?The fact is no Toyota, (Other than the Toyota Supra that has a BMW engine) uses a grade of gasoline above higher than 87. The electronic control module of most Toyotas is tuned to 87 Octane. Many people believe that opting for a higher grade gasoline will improve the performance of your car, but this is not so.
Can I put 93 gas in my 4Runner?You must only use unleaded gasoline. Select octane rating 87 (Research Octane Number 91) or higher. Use of unleaded gasoline with an octane rating lower than 87 may result in engine knocking.
What kind of gas does a Toyota need?Thankfully, filling up your new car couldn't be simpler. The kind of gas a 2021 Toyota Corolla takes is regular unleaded gasoline. There's no need to purchase premium fuel for your Toyota—it doesn't need premium and its best to save your money. Regular unleaded will keep your car running in great condition.
