Im betting on the regular oil and 5000 mile changes. If it were necessary to use synthetic oil to avoid costly repairs down the road dont you think toyota wouldve recommended it FWIW over the years Ive run a number of cars well above 100000 miles without problems on conventional oils and the only 2 engines that have suffered any lubrication related failures (a bad timing chain and excessive oil consumption)

- ok 10) Modifying your vehicle for FE. - cost of modifications will probably outweigh fuel savings. 11) Switch to synthetic oils. - Ive done this and it probably works to save fuel. However if one stays on the same change schedule the higher cost of the oil may outweigh the fuel savings. For this to lead to actual savings one needs to go beyond the 8000km between oil changes recommended by toyota.
guys... keep in mind that higher octane fuel might have cleaning additives and possibly less E85 than regular fuel. This is just some reasons why you get better fuel economy with higher octane in an economy car like the yaris... that do NOT require premium.

I think high octane fuel will not help on fuel economy because the octane is the measure of the self evaporation of the fuel in comparison with the compression. Low compression cars use regularly regular fuel because the octane is low. If you put high octane fuel into a low compression combustion chamber when the piston is compressing the air and the fuel the fuel will not turn into gas stage completely.

PSyour premium gas may only be 4% higher than regular but over the life of the car that will
that has developed a product that installs in-line with the fuel system and pounds the fuel with high power electro-magentic pulses to break the long hydrocarbon chains into smaller more combustible sections. This product produces gains of 12-15% on diesel (and fuel oil based) systems and 8-12% on gasoline engines. I have been testing one of their gasoline units on my completely stock 08 red yaris
So let me put it this way. Does anyone here regularly change their yaris fuel filter and if so how hard is it If not what is the logic behind not changing it thanks
A piece of advice that someone would give you if I didnt anyway... do not let your yaris run down to fumes regularly if at all if you can help it. Doing that will help extend the life of that fuel filter youre worried about. This is why the manual says do not let the car drop below two bars of fuel.

All toyota automobiles use lifetime fuel filters. That means by design it will outlast your car. However filter media become clogged prematurely from contamination through the filler either by dirty refueling equipment or simply dirty fuel (like from a jerry can that has been sitting in your garage). You should not change the filter unless you or a technician have diagnosed unequivocally that the fuel
I see But if calculate is it worth it I think it is.....though I havent done the calculations The 98 octane in Australia is 6c more than the regular fuel 6c more doesnt make a big difference in the total price for the yaris and having the 4c discount receipt _ Jaspie
87 octane with 10.51 compression is the major advances in computer controlled management head valve design chamber quench design timing and fuel delivery. The whole idea is to prevent detonation higher octane fuel means more cylinder pressure higher temperature before detonation happens. Its kind of like adding antifreeze to coolant to allow the water to boil at a higher temperature. Since the yaris

Some missunderstanding about this may come from its overly abundant use in auto publications where multiple aftermarket parts are tested over a range of gasolines to develop baseline performance figures. Its a lot more involved than just pumping gas - 07WyarisRS is correct and obviously has some (or probably a lot) of previous engine building tuning experience. This might make things slightly clearer

Wouldnt toyota simply recommend premium if that were the case Premium only costs roughly 10% more yet according to you it improves fuel economy by 30%. That means

The following service was done to the vehicle. 50 miles at purchase installed K&N washable air filter. 500 miles oil change standard Valvoline 5w30. 2500 miles oil change with standard Valvoline 5w30. 5000 miles oil change with Semi synthetic Valvoline 5W30 cleaned air filter. 10000 miles oil chance with
want to test the authorities) the car got 42-44 mpg. The only fly in the ointment might be the percentage of alcohol in the gas which might be greater now. Oh and the 5200 miles to AK the engine used regular Walmart oil. On the trip back Mobile 1. There was no difference in mpg. you cannot compare an echo to a yaris. They do not compare at all. The yaris gearing and final drive is different. toyota
in my experience the higher octane is useless and a waste of money for the yaris. I just finished a tank last week with 91 octane ( here in Canada we have 87. 89 and 91) and i got a lower MPG than usual. Stick to regular and you will be fine. True it will be zippier but doesnt burn off as well as the regular in the yaris.

In the yaris the first two tanks were regular. I felt the acceleration could improve. Since premium
The octane specified in the owners manual is a MINIMUM requirement not a recommended octane rating. Your warrenty will NOT be voided by running higher test fuel. I see higher ignition advance under all conditions (via scangauge) with 91 than I do with regular which tells me that the car is actually taking advantage of the higher octane. The people that mention their warranties being voided on this forum would do well to learn about octane ratings and meanings.

I reset it every time I fill up and always fill the tank right up so whats going on here Is it boosted
I use cheapest regular fuel i can find why would u use premium

Quote Originally Posted by .Kevin. Shell gas any good I heard chevrons techron runs well Im one of those people who think premium is best no matter what lol. Have you noticed the wrx will burn quality fuel quicker than ethanol fuel aswell I use regular 87 10% ethanol (CT). Premium wont do anything extra for you. My fussiness is that I only use top tier gas which is either Shell or Mobil in my area. I also heard that Chevron is the best but its not available here.
by TLyttle Sure. They left it to the owners before 1974 and look at what we got gas guzzling scary handling ugly pigs and we were happy for them because of the chrome ashtrays. Be serious. And who was selling all that crap to the American public Cmon guys I remember the ads. I also remember buying a couple of Brit cars that wouldnt take two bucks of fuel on a dead-empty tank. Now I drive a yaris
Theres certainly been tons of talk of this with Hyundai Kia Honda & Ford. They are earning 40 mpg ratings are most consumers are reporting much less on the highway. All the while lower rated toyotas like the 36 mpg Corolla get better mileage than the 40 mpg models. In fact most toyota owners regularly report higher than rated mileage. We yaris owners can attest to that. 2936 I get 3241 oddly enough matching the pre-2008 EPA rating.
Research Octane Number (RON) 91 is regular unleaded fuel.. ie 87 in North America. You probably get better mileage out of 95 because it is ethanol free you can see it this way.. regular unleaded may contain up to 10% ethanol which increases fuel consumption. So you do the math see if paying premium for ethanol free fuel is monetary more economical than using regular but getting worse mileage.

ive mentioned this in another thread on one of my regular drives i go past a fuel truck re-filling station and ive noticed trucks from all of the major fuel companies filling up from the same tanks. that would tell me that this is the exact same fuel they are using and selling under different brand names. are any addities specific to companies added at the actual stations i would doubt it myself. ive
E10 is a bit cheaper here in Germany about 3%. I tried it once when I had to fill up in Germany and the loss of power was unbearable to me. Sad that toyota didnt add a sensor that detects the mixture of fuel like Ford does ( However I usually go to Luxemburg to fill up its only about 10km and standard fuel is 15% cheaper than here (but still almost twice what you pay)
