Better grade 89 or higher octane vs 86-87 "regular" octane

chevron techron gas only contains 1oz of techron for 55000 gallons of gasoline might as well not be there. however if you want to clean up your engine something fierce, I recommend using the whole 12oz in your tank, it wont hurt your engine.

there is also a cleaner that will clean out your entire engine of carbon buildup better then techron or any of the popular brand cleaners, was designed to be clean for marine use, cant remember the name at the moment. It requires some knowhow though, You put it into the engine directly through a vacuumme line at about 3k rpm then when it drains the can you instantly shot of the engine and let it sit for about 30 - 60 minutes.
after this you are good to restart the engine, there will be lots of white smoke, dont worry your engine is fine it is just the product and carbon buildup exiting out the exhaust. After the procedure change your oil withing the next 100 miles.
once again this is the most intense and best method to get rid of the carbon buildup in the engine, but I wouldnt recomend it for any car with less then 150k miles on it, unless your car has been running rich and you are now failing smog for high NOx

Seafoam...

BG makes a great product that the Toyota dealership uses. I have used them various cars with favorable results. Ask your parts guy about the BG fuel system cleaner (runs through the gas tank).

lucas is amazing stuff. I use the gas treatment off and on to keep everything clean. The car runs smoother and I get better mileage.

I also used lucas oil stabilizer for the engine and transmission in my older corolla - it smoothed out rough idling and shifting. I haven't put any in the yaris because I've been running synthetic oil since day 1.

My friend couldn't shift his old beater into gear, poured some lucas in the tranny, and drove off...

As for gas I like chevron and shell. There is a noticeable difference in power and mileage over pretty much everyone else. I avoid arco like the plague.(I know about 10 people who have gotten "bad gas" and had to drain their tanks)

I think what you are thinking about is seafoam. My auto shop sells those services for 60 dollars. I can tell it makes a massive difference before and after. Also you can simply add a can to your tank of gas and it will clean the injectors and pistons still. I put one in a friends car and the exhaust started to smoke after a few minutes from the carbon being removed.

I would reccomend doing that service every 30k miles. To keep your engine running clean as possible. I have noticed every time the car has very minimal amount of smoke i ask them what kind of gas they use. They always say chevron. One car had 180k miles and there was no smoke. Well just one baby puff. One car with 30k miles who ran only cosco gas the car stalled out so many times from the massive amount of carbon the smoke traveled out past our shop into the street and nearly caused a pileup as it was so dense. We had to drive it around the local neighborhood trying to to get it to clear up but it was smoking for atleast 15 minutes. When we got it back to the shop we had to let it idle for a hour before it stopped smoking. I have never seen anything like it in my life. Since then i made it my mission to advise all my customers to stay away from discount gasoline. ANd belive me this customer after witnessing himself the effects will never use it too. Man did that car run smooth afterwards though. Idle went perfect the car had a lot more pep.

Right on. It's cheaper than I thought, too. I got a 32 ouncer for $10. At 3-4 oz./tank that's only $1 a dose or so.

Using premium is like throwing $ out the window.

I notice this too...i used the highest octane but i get poor mileage
why is that... going to try this lucas additive and see

[NJBob]

Some on board computers will accomdate/adjust for a different octane...perhaps our Yarii does not. My '98 Neon R/T required 89 octane and DID get better mileage with higher octane. It was a DOHC high performance engine however.

sounds like a spam... is he advertising...
