Topic: STP - Gas treatment in new car

[newbee]

Hi everyone

I am driving Corolla Sports 2005, 16k done. I have couple of questions to ask, ur feedback would be appreciated.

1. Is it ok to put 89 grade gas for a while and going back to 87 grade gas ? and
2. Is it ok to put STP - Gas treatment in the car, once in a while....i would say after 5 tanks ?


Need your feedback.
Thanks

I have one question of you - Why would you wish to do either of these things? Are you experiencing any driveability problems?

[articsteve]

Yes, what is the situation.  Just keeping on top of the fuel system?

STP is essentially diesel fuel.  Try Marvel Mystery Oil.  Now available at Canadian Tire. Finally imported into Canada.  Cleans and lubes fuel systems and injectors.  Great stuff.

The 87 Octange Fuel should be alright and a small bottle of fuel injector cleaner about every 5 tankfills won't do it any harm at all. I would try to plan the timing of adding the injector cleaner to when you are going on a trip on the highway. It helps clean it out a little better that way.

Thank you guys....I am having no problems what so ever but I am trying to keep my baby healthy & for that just wana feed her healthy food....
I like Barrie's idea. Thanks guys.....

What is the consensus on Lucusoil's Fuel System additive?  My father and I have used it a few times.  It seems (*seems*) to improve throttle response slightly.

[articsteve]

Marvel Mystery Oil.  Stuff is amazing for sticky valves and injectors.

[mrthompson]

I'll have to give this stuff a try.  It's available at Crappy Tire, you say?  How much per bottle, do you recall?

Just curious - why would anyone need to add gas treatment to a new car? I can see it maybe after a few years or a bunch of kms, but isn't it just a waste of money when the car is pretty new?

I guess I have a similar question - about fuel - is there a problem with using premium fuel (like Sunoco 94) in a car like mine (Aerio) or any other more common runabout?)  I used 94 in the 850, and my father claimed it was probably the reason mine felt more powerful than his although mine was 2 years older with about 100 000 more km (both had the 20 valve engine - Volvo also offered a cheaper version of the 850 with a 10 valve...).  If the really good stuff was good for the Volvo, would it be OK for the Suzuki, if only as a once a month treat?

[sterling]

Sure, why not. It's not going to hurt anything. It's not going to help anything. It's your money.

[ovr50]

It's not going to hurt to run higher octane gas than needed, but it does cost you more; and, in most normal daily commuter-type cars, it does absolutely no good.

In current new vehicles, I would inclined not to switch back and forth between octane levels as the "adaptive" systems in modern vehicles get used to one level and generally perform better if you stay there. It also depends on what your Manual says, some say "use 87 octane", others say "can use 87 octane, but for improved performance, use 91 octane". Clearly wasting money in an 87 octane only vehicle.

...Any thoughts on the validity..LONG TERM..of using Sunoco 94 OR ShellPremium V Power for their "extra" benefits( OTHER than HIGH OCTANE..NO PING for Turbo/Supercharged high compression engines)..in other words is their additive package WORTH the 10cents a Litre EVEN IF YOU DON'T NEED THE OCTANE RATING......clean injectors,10% Etanol wif Sunoco acting as an anti freeze etc..etc...??

[Scaerio]

Wow - I was expecting Saffi's post to mention Beano, or some other gas treatment!

I'll have to give this stuff a try.  It's available at Crappy Tire, you say?  How much per bottle, do you recall?

I just bought a bottle so do you think I could remember the price.   I think its ten bucks, maybe 12.  24 ounces. No mls or metric so you know its gotta be good.

Its a subjective kind of thing; correction of lifter and valve sticking or possible injector sticking.  But I recently developed some lifter noise on my 2.5 litre single Vanos Bimmer motor and I added this stuff to the gas following the instructions and it's gone.  The motor has 196K on it and it is not started for 6 months each year so thats what I though was the cause.

Now the other car, the 87 924S 2.4 Porsche had a very slight hesitation going thru 4500 to 5500 rpm when I bought it.  I assumed it was the injectors.  That was 4 years ago.  Well this year it got horribly noticeable and I've run 2 treated tanks and its essentially gone.  This car has 194K and sits for about 8 months a year.  Previously, I tried all the usual fuel injector cleaners on it.  Zero effect.

I got wind of this stuff about 7 years ago on a 2 stroke engine building BBS (something I used to do) and this Texan guy was a builder supreme of all engines and he used to yell at me to use this Marvel Mystery Oil.  I kept telling him that it wasn't available and my sister claimed she could never find it in her state.  So low and behold I'm in the Owen Sound Crappy and I'm staring hopelessly at all the fuel treatments that have never done a dam thing for any car I've owned in the past 25 years and there it was.  Big red bottle right at the end of the gas and fuel injector row.

It's like a red transmission fluid.  Smells really sweet.  I think it is 4 ounces to every 10 gallons.  Of course I over do it.

Anyone else tried this Mystery Marvel Oil?

[mrthompson]

Cool...thanks artic.   

[newbee]

it seems from discussion sunoco sells good gas than Esso. I use Esso gas 87 and this what is in mannual but don't  you need something extra to clean your fuel tank and injector for new and old cars?

[No H2O]

I use Chevron Techron Fuel System Cleaner. Supposedly highly recommended. I'm not having any issues; just trying to prevent them. I add it twice a year; spring and fall.

I don't know if it is available up here, but I get a few bottles every time I'm in the US.

[maritime_storm]

Actually, I have used it over the years(freed up the lifters in my 1984 Chrysler Fifth Avenue). Now here's the interesting thing, 2 groups of individuals who one won't expect to agree on much of anything swear by Marvel Mystery Oil. Saturn fans swear by it for freeing up stuck oil control rings on  pre-98 Saturn engines and owners of Dodge trucks with the Cummins Turbo Diesel swear by it as a fuel additive, they claim they can scrape about 5 MPG more out of the already efficient Cummins with it. We sell it for $7.99/950ml bottle. Like all additives, some swear by it, some swear at it. Nothing but oil goes it my vehicles, I used Howes Lubricator{Cummins Warranty Approved} in the Dodge, and 3 times a year the ION gets a bottle of fuel injector cleaner. I figure it this way, if GM & Cummins aren't recommending the use of any additives & they spent millions developing their products, who am I to argue with them.
