Anyone tried Fuel or Engine Additives?

[Pisces69]

Most of the Starlets just go and have their carburetors stripped down and cleaned. Starlet owners go and have them cleaned once they buy the COE Starlet.

 

Most of the old Starlets have new twin webbers installed.

u gonna make him miss his TC-ed ol' ride pretty badly.........

Dosen't matter. Those r all good memories.

 

Now got more choices & better looking with more power too.

 

But as our age catches up, cannot go too fast anymore. Have family to think of.

Usually no but if they are using the Aisin's, highly modified. Those with SUs are maintenance free. Webers need to be tuned occasionally. Single carburetors all of them.

Some of us use STP injector cleaner whenever on long drive to north and it seems to help.

 

Know of people change injectors. But dismantling and clean then might be a precision job not sure if OEM workshop will agree to do. Have you ever got them cleaned the way you said if I may ask?

[Genie47]

Brother did with his old 164. Regular thing every year. I have not even clocked a year's mileage with this car yet. My first EFI car. Previous was carburetted and it saw carburetor tear-downs twice. Didn't use these additives in fuel even with the carburetted car.

One big advantage with webbers is that u can easily change the jettings to suit driving conditions. Another is the beautiful sound it makes when angry. Yup, I think u r right. It's a single carb but DCOE if i'm not mistaken.

 

Agree they used to need more tuning then others. Jap carbs r more user friendly. But I think the newer webbers r also less troublesome. My fren put one in his AT171 without much fiddling a few years back.

Not DCOE lah. DCOE is side draft. Damn F***ing angry and loud. Usually with a adaptor plate it is a DGEV progressive (rare) or a Maserati/Ferrari sourced DCNF which are both top draft. A recently decommissioned Starlet had a single 45DCOE installed. The car was faster than the turbo Starlet when it took off. Incited many stares because its was louder than a prime mover. All in all, a bold experiment to prove that power and economy does not mix. It averaged about 200km for a full tank.

 

The SUs on the other hand got this "shuck shuck" induction sound. Practically maintenance free but the jetting needle is the beauty. Can actually machine it down to the size needed for your engine.

I missed this post by you. STP's engine oil treatment is nothing but viscosity index improvers. Cook them too much and you get sludge. More like your regular snake oil.

 

If there is any additive for engine oil you need, it is is Valvoline's Synpower Oil Treatment. This stuff is selling at Autobaccs but if anyone can suggest a cheaper source it will be great.

 

See the archives here on it and the post by me contains a link to the analysis results from BITOG. The thing is thicker than pudding and has loads of moly in it.

 

Now if you know your oil has no moly in it and would like to supplement it, this additive will be it. The bottle instructions say to dump 1bottle for every 4qts of engine oil. DON'T! The whole idea is to supplement and not reformulate. BITOG members have been suggesting 1oz/qt of oil.

[Genie47]

Fuel additives can do potential harm, like increase engine oil oxidation and nitration.

 

Yep, more power and at the same time make your oil's life shorter and in the end harm the engine. Terry whom I send my oil for analysis always ask if I am using fuel additives because my wear is rather high. Actually boiled down to the Si that is sucked in.

So you think your brother dismantles and cleans injector would mean only stupid people in the world use injector cleaner.

 

Have you heard of on-car and off-car injector cleaning? The latter is usually meant for those badly clogged injector when normal injector cleaner doesn't help.

 

Since you believe only in off-car injector cleaning, your brother must be using ultra sonic bath for cleaning, flow bench machines for static and pulse testing for leak and flow after re-assembly, dielectric test for the coil after cleaning. Personally cleaning injectors unprofessionally can compromise injector performance unless your car electronics are coarse tuned. Guess you probably will disagree, thinking injectors are just like any nozzles except for their wiring.

 

When injectors are seriously clogged, most would think the couple of hundred dollars spend for proper cleaning would almost pay for another new injectors unless they are special to type or the cars uses exorbitant injectors.

[Genie47]

For crying out loud that is an Alfa 164. The fuel lines are changed every year and cleaning the injectors by the professional is just too good to pass up. FYI, that is a COE Alfa and like anything Italian, fire is somethng you consider on the back of your mind.

[Pisces69]

An old friend used to have a RWD Starlet with a DCOE and done up to 3/4 race.

 

Used to eat Alfa's for breakfast.

 

When he entered races at PG he drove a full race RWD Starlet which he shared with friends. I always enjoyed taking a ride in his car. Always got the blood flowing.

 

If he stopped at the traffic lights & TP pulled up beside him, he had to switch off the engine.

hmmm ic .. heng ... almost bought it today ...

 

No V power over here ...

I went with his hunch about fuel additives in my petrol. Lo and behold, the spark plugs were covered with a rust red-brown deposit. Tell tale signs of fuel additives. Must be the Caltex Gold RON97 across the Causeway. They must be using additives to bump up the RON number.

[Viviobluerex]

That's Great! But so far have not received a cool response from a petrol car user yet...

[Viviobluerex]

Mr.Fuel? A new brand? I hv not heard anything before for this brand.

 

Next meet up bring the bottle let us see see leh..

 

[Viviobluerex]

No wonder lah! Aiyo. sounds like my engine soon will up the car..
