any of you guys heard of this?
so i was talking to my neighbor the other day. hes a backyard mechanic and the dude knows his ****.
he was tellin me that a buddy of his used tranny fluid to clean his engine.. like to flush dirt out and stuff and that it worked really well.. he explained to me that automatic tranny fluid has so many detergents and cleaners that it cleans out pretty well..
he just told me that if i were to use it to drain the old oil. put in the ATF and just let the car idle for about 10 min and then drain that and then put the oil in there...
any of you guys heard of this? or anything like it?

It's actually pretty common especially among older mechanics/car guys. I've never heard of REPLACING engine oil with it, I've only ever heard of adding a quart or so to the engine oil before an oil change..
I probably wouldn't do it personally, though.

Yeah my homeboy uses it as an engine degreaser on his Honda Passport. He uses a toothbrush to get into some of those incorrigible spots and a bunch of old tshirts to wipe it off. I take the same approach but use vinegar instead. Vinegar works wonders. Just be sure its dry before warming the engine up. It carries quite a scent when hot. Its not a terrible scent but its one that doesnt belong in an engine bay.

i always added a little seafoam before an oil change if i felt it was sludgy. i had a motor i seafoamed blow a headgasket (not the seafoam) so i pulled it apart and it was clean on the inside. but hey, if you use decent oil and change it on time i dont think this is much of a concern. unless you own a mercedes. every time i change the oil in one it's extremely sludgy. maby it's just dumb rich people not changing oil
#5
im kinda thinkin about doin it next oil change.
ive already done the seafoam oil treatment.. and idk.. i dont rele notice a difference in the feel of the car. the oil is staying clean. i mean. it looks normal. haha. im not even sure. im just kinda curious to see if it does anything..
i think that ATF isint any thinner then motor oil.
#6
eh, personally i wouldnt do it. if you want to flush your engine, you can go to a oil change place or flush it yourself. they have a flush liquid made from soybean or some other bean, i had to get it done a couple years ago when i had some engine sludge and there was a huge difference after
#7
Do a search on engine flushing and you'll see that its not a good idea.. I dont know about that tranny fluid thing, but I wouldn't bother. Change oil on time, a little seafoam once in a blue moon, and leave it at that.

Personally, the only people I've come across who still do this are hillbillys with dirt track "race kawz"...

Yeah my father in law (40+years automotive pro. exp.), has suggested putting 4 oz. in crankcase to get rid of lifter tap. It really works good and everyone knows these Max's are known 4 lifter tap at start up in cold for about a couple of seconds. Flushing out crankcase/tranny is never a good idea on anything with high mileage, I don't believe in using seafoam in the crankcase either, seafoam works well for intake cleaning though. Try just 4oz.'s of tranny fluid before you dump your oil, just 4oz.'s though, no more.

I only speak the truth
VEvolution.. yeah, I wouldn't personally do an engine flush, as I know none of my cars are in need of one. I was just saying if somebody was dead-set on doing an engine flush, they could just use an actual engine flush product rather than some "trick"

is the soybean one bad though? i looked it up after i got it done and theres no harsh chemicals, just natural flushing stuff.
i barely remember when it happened, but i think i was at 390,000km at the time and i rode out regular oil until 5000km, after the flush i switched to full synthetic every 3000km

Here's the skinny guys...If you change your oil regularly, then you don't need to flush/clean your engine with anything...
If you neglect your oil changes, then yes, a flush here-n-there may help keep it clean..
If your oil is unusually black/dark colored after 3000 miles...then you have other issues going on, most likely some blow by due to worn piston rings..

My $.02
The seals and gaskets in the engine are not designed to withstand the chemicals in the transmission fluid. There is a risk of damage to the seals and then developing a leak. I have witnessed more than one engine developing a leak around valve seals after using a flush before oil changes. Granted those were older V8's and technology has improved over the last 20 years.

I've used ATF for years....
for older cars, then I drive the car until it's a quart low (usually about 3000 miles), then add a quart of ATF and change the oil at 5000 miles. do that for a couple changes and all is well.
For newer cars, just change at 5000 miles and don't worry about it until the car has at least 100k miles on it.

the problem with flushing out an old engine or transmission is that the seals are worn but its all the old gunk & junk that keeps them from leaking. Everyone likes to blame the flush but all it did was its job. I use ATF on a lot of things as a penetrating oil (both automotive and non) because of all the detergent chemicals.
.
As to its "weight", I've never heard of one but I seriously doubt that it is like SAE 30. Give this a try - put some engine oil and some ATF in your freezer for a few hours and then try to pour out some of both. If ATF was like 30 weight, your transmission wouldn't shift.

When was the last time you drove a 3 gen auto when it was below freezing? that sucker does NOT want to shift until it's run for a few minutes to warm up.
If I had to guess at viscosity, I'd say more like a 5w20 or 0w20 or something like that.. It's pretty thin when it's cold, and still about as thin when it's hot.

My bad, I was thinking of gear oil.

Viscosity
Esso ATF DEXRON®-III / MERCON® is
available in one grade. Compared to SAE 5W-20
engine oils and SAE 75W-80W gear oils, it has
about the same high temperature viscosity with
approximately a 5°C fluidity advantage in the low

hahah.. just when the car is cold it dosent want to shift..
i guess if matt does it then it cant be THAT bad..
ill prolly let it ride until it burn a little more oil.. i just put some oil in her today and since i dont have an odometer.. lol.. i cant tell if ive hit 3000 or 5000 miles

I wouldn't do that myself. (and I'm the Maxima GOD, so listen to what I have to say or :matt93se: )
How long has it been since last oil change? and how much do you drive a day? just do some guesses... (my work is 40 miles each way, so that's 400 miles a week. add 100 for random crap cause I live in the sticks and I drive 2000 miles a month..)
also keep in mind oil lasts roughly 4-5 months on its detergends package once it's placed in an engine and exposed to operating temps, unburned fuel, and oxygen. as soon as it does that, the detergents start breaking down and they last 3-4-5-6 months depending on weather and conditions.
if it's been more than 3 months since you last changed it, I'd stick a quart of aTF in it (hell run it a quart high if the pan is full... you won't hurt anyhting. my engine didn't run weird until I had 10 qts of oil in it... ) run it a week or so of daily driving (500 miles or 2 tanks of gas or whatever), and then change it.
howzat? we're dealing with opinions, horseshoes, and hand grenades here.

i dive maybe 8 miles to work and back. prolly not even that.. wich is prolly not the best for my engine.. its always warming up... when it gets to operating temp im already halfway to my house. lol.
but alright matt.. ill put quart of atf in a few weeks when i change my oil

well these past few weeks ive barely been riving. i change my oil about last month maybe.

yep its good to get on the highway every once in a while to get nasties out of your engine and such, i usually go on the highway Sunday nights and get it up to 150 for 15 minutes since i as well only do city driving and rarely go over 100

wtf.. lol. u must be ****tin me..

now that the engines rebuilt im comfortable going around 160, before i wouldnt do more than 120

just use good oil and chg your oil regularly @ 3000-4000 and the oil will clean you engine as it should anyway......buying a used car that has been neglected and has sludge buildup maybe a little ATF could loosen and clean it but I wouldn't make it a habit doing that.......I'm a big Pennzoil and Royal Purple fan ...all the engines I disassembled and inspected always really looked good on the interior and it's bearing surfaces that were using Pennzoil....

of course km/h lol. theres a highway here with no speed limit so i just let er rip. i rip nearly every night on city roads for a hour or two and just cruise to see whats good as well. in the last 2 years, ive put 42,000km on it
