Is it normal?

[Stepper]

Is it normal for a car to take longer to warm up( my engine vibrate quite a lot when cold start) when engine treatment( a blue bottle, dont know wat brand) is added.

 

My mech say it will thicken my engine oil and it will make my engine quieter.

Your mech said half ture that older car uses thicker engine oil but not for quieter. Change the enigne oil frenquetly will help only.

But I dun think the vibration all came from the new engine's treatment. U should adjust the fuel air mix ratio. possible the idle speed not enough.

Clean your carb & also check whether your engine oil is due for change, assuming other parts on the engine are ok! Used 50 weight oil instead of 40

[Stepper]

but b4 the engine treatment everything is ok.

engine oil change due next month, maybe will bring forward and also do carb cleaning at the same time.

[Vtim]

I assume you are using mineral oil Mineral tends to break down when it's about due to change, ard 5000km, so I think a change of your oil (try using Syn, weight 50 oil) will clear your problem.

[Stepper]

I using semi syn shell oil, maybe i buy the oil from jb that why breakdown easier

Stepper,

 

I dun think it is due to the fact that the oil was was JB..

 

The treatment you added could have created some residue....

[Stepper]

if it really really create residue what can be done? flush the engine?

 

thks.

[Vtim]

Was told that there are some syndicate using recycle oil and past it off as new in Malaysia . Don't know whether it's true or not

[Stepper]

heard of that before too

[Gadgeter]

Just change your engine oil more often. It will "flush" off the residue.

 

It happens to my friend civic too... Understand it was because the ex-owner added some engine oil treatment..

[Mondeo]

If can DIY, just station the car and let the engine oil drip overnight, then put some new engine oil next morning but dun screw back the oil tray screw but need changed the filter, start engine and run for 20 seconds and off it, and let the oil drip for another hrs, screw back, should be better.

I hope you did not add the STP engine treatment (comes in a blue metal can, opens with a ring tab like those on a coca cola can)

 

that sxxt is vile, man! Long time ago when I just got my 1st car, backside itchy added a can of that sxxt.... end result, engine oil cooked off leaving black gooey mess in my valvetrain, had to do top overhaul.....definitely not for high revving jap engines

if ur car vibrate like a boneshaker, check if your carb is properly tuned (which most mech dunno how to tune properly) If u are kiasu enuff like me, take out the spark plugs every 2000km and observe the characteristic

 

As for engine additive, forget it.

 

Why dont u try pulling the choke on ur GL? I remember 5-6 clicks total travel, pull about 2 clicks during cold start, unless your GL is a later model with auto-choke

Yeah, that's what I try to say on my earlier post.

[Turbobrick]

Check your choke and make sure it works, also consider checking out your thermostat since it's taking longer than usual to start.

 

Also, oil change is definitely due for Ur Civic.

[Stepper]

where can i get a reliable mech to have my carb tune?

b4 i add the engine treatment, i already use the choke(3 clicks, 1st 2 clicks no effect) when i start my car in the morning, the rpm will be at abt 1700-1800 rpm, now only abt 1400-1500 rpm(no vibration) ,when i push the choke back(after abt 30-45 sec) the car is like dieing off and coming back.

[Stepper]

not using stp. the one, my mech use is a blue plastic bottle one.
