how much ???????????????

[nitro_freak_123]

hey guys jst wanted to ask a simple question about after run oil ... how much do i need to put in my car (carb and head ) and would i have to put it in after every bashing or race session ?? i got a thunder tiger ssk pro 15 pullstart engine any commets would b much apprecited thanks nitrohead !

 

[SpitFireV12RR]

It depends...if you're going to go bashing in over a week, yes. If you're going to run in a day, than no, but me(And probally alot of guys) do it every time, just out of good habit. I just squirt a few drops in the glow plug hole and a little spray of WD40 in the carb opening. Also remember to put you piston at BDC*

ok nice1 spit bro ill bear it in mind

 

[nitro_freak_123]

spitfirev12rr :::
when u say bottem dead center is that when it is at the bottem of the stroke so u dnt put any after run oil down the carb then keep me posted

 

[SpitFireV12RR]

No...these cars have tapered cylinders and if you leave it at the top of the stroke while it cools, you can have premature ware. You would still have the ARO in there. Just a tip...there are a bunch of topics on this. The search button at the top of the page can help out.

awww rite thanks mate

Well, what Spit forgot to mention is that, after you put a couple drops in the glow plug opening, you need to yank the pull starter a few times to work the oil around, then put the piston a BDC.

One other thing, I would not suggest putting ARO directly into the carb. Sometimes the oil can have a negative affect on the O-ring. I tend to not put any type of oil into the carb myself, but that's primarily my preference.

Isn't WD40 considered a "Degreaser?" I thought it was supposed to lubricate also. I wouldn't consider WD40 an oil, but I guess people would.

 

[Monkey Wrench]

OK then, let me clarify. I tend to not put any oil, degreaser, solvent or likewise directly into the carb to avoid any damage or premature wearing of the O-rings. This is my personal preference. My theory is, if I add ARO directly into the P/S and turn the engine over enough to spread it around, I don't need to add any directly through the carb.

WD40 is a lubricator. Thats why it loosens bolts. (What it was made for). Its a good lube and can be used as ARO (traxxas even recomends it) but my own preferance is just regular ARO. Its alot thinker.

 

[nitro_freak_123]

ok thanks guys thank monkey i have put after run oil dwn carb recently but i prob just put dwn the glo plug hole insted init keep me posted guys

 

[SpitFireV12RR]

What? It helps if you talk in complete sentences and spell the stuff out! Sorry if I'm mean, but it takes me about 5 minutes to deciphure your sentences.

first off a few drops may not be enough...I squirt a buttload of it (MMO/tranny fluid) it down the carb throat myself....I've heard of the O-ring thing too but find it's alot safer and easier to clean off the filter and carb throat than the glow plug hole after running at the track......like MW said my prefference.....then I bump it on the box w/ the ignitor on til it won't start.....unless I ran it dry...which I do alot and you really shouldn't

 

[dannyd]

i use it after every run. i use about 3-5 drops in the head and carb. i also used it when i was rebuilding my .15fe (testing myself on rebuilding a mill)

 

[Monkey Wrench]

Nitro, it's purely a preference as to adding it via the carb or not. The key, in my opinion, is moving the oil around after you've put it in. You'll get the best results by turning it over after adding it, work it around a bit.

I understand what your telling us, no worries.

 

[racin_38]

as these guys have standed using ARO after every outing with your nitro will greatly extent its life ,simply because it is adding a layer of oil for the next start up and rids the motor of moisture that is caused by the fuel .

and i also understood what you were saying

A degreaser is a solvent by definition, a lubricant is dissolved by a solvent/degreaser,, no single substance can be a lubricant and a solvent.

WD40 is a rust breaker/low surface tension penetrant, and in general a solvent that lingers longer than most solvents, it is only a very temporary substitute for a lubricant in as much as it has a very high evaporation rate.
Once it evaporates, oxidation accelerates which is the main thing that a lubricant should prevent,,,But, overall, it isn't really a lubricant at all.

I should add I use the long nozzle on my old ARO bottle to get it down in the crank....I do try to miss the whole carb....mostly because I heard the O-ring thing and figured it wouldn't hurt any to try and miss the carb since it really doesn't need any ARO....turn the Flywheel til you see the port and I basically fill the crank real fast...then it slowly runs into the case......and then bump it over.....

No fair, Jeep! You read the can!

I tend to not put any oil, degreaser, solvent or likewise directly into the carb to avoid any damage or premature wearing of the O-rings.

For the benefit of those who have come by this idea from the OS Engines manual, I should probably point out the following:

We recommend application through the glow plug hole or through the air inlet. When O.S. states to not put after-run oil into the carb, they are referring to the fuel inlet. If you introduce the oil into the air inlet, you will have no problems.

When administered through the air inlet, there will be no effect on the O-rings due to the use of petroleum-based oils. You can only damage these by pulling off the fuel line and squirting oil down the fuel inlet. Stupid, I know, but the manuals are unclear.

Agreed, and in addition there are low levels of acids in WD-40, and acids etch. I don't want any etching going on inside my engine. Lot of people use it though, and for the record the WD in WD-40 means water displacement, which is the main reason for ARO, I just dont think it's best for this application.

My pref: per the OS Engines linkie above, half a teaspoon down the carb air inlet, crank the engine over, no need to pull the plug because by cranking the engine the oil finds it's way to the P/S the same way the fuel does. 4-5 drops is just a simple waste of time and oil. Removing the plug for the purpose of putting ARO in there 1) only gives you one more opportunity to wash dust specs down there, 2) further distorts/scratches the copper gasket, leading to compression loss, and 3) any oil put down the glow plug hole blows rightout the exhaust as soon as you crank the engine over.
