ATF in a motor,30wt oil in the fuel WAS OLD advise by the guy working on them for the last half century.At one time ATF was considered the ultimate cleaner when no others were out there.Injectors and pumps,clearances were not as critical as today.In another words THINGS CHANGE.Bows and arrows and muzzle loaders are NOT used by our armed forces any more.

 

Wow, you're pretty easily amazed. This one will REALLY amaze you. When you wake back up from fainting, tell us what you think:

I don't just put my old engine oil into my fuel tank-I dump EVERYONE ELSE'S old used oil in there too! I go collect the oil from shops, and I run it through a 10 micron hydraulic filter. Then, into the tank it gooooooes... Now keep in mind, this is in a p-pumped 12v, but still...

So far as the fuel filter, the only thing I've noticed is that it won't pass quite as much oil as ordinary diesel fuel, probably because the oil is thicker. It shows up as sputtering on the very top end, well above the rpm to which the engine was originally governed. I know it's not actual clogging of the filter, because I got caught without oil one time on a trip and had to fill up on diesel. The fuel starvation sputtering went away for that tank, and came back again when I was able to get back on oil. That fuel filter currently has about 4k on it, so the jury is still out on total filter lifespan. In any case, even if I had to change filters every single tank, it would be worth it financially. As it is, even if the filter plugs solid tomorrow, one filter every 4k vs enough diesel to go that far is basically free by comparison.

 

LMAO!!! That doesn't count. A p-pump 12V will run on Canola oil right out of the fryer mixed with left over bacon grease.

 

Geez , I am almost afraid to tell. I have a 78(I think) Ford 9000( straight truck for use on the farm) with a Detroit Deisel. It has 440000 mi. and has had a quart of trans fluid in both tanks every fill since new. My uncle bought it in the late 70s and we got it from him when he retired 8 or so years ago. I have never used it in the new cummins but it was and is a very common practice with the older diesels. It cleans the injectors and lubes the pump. (so they say) Other than leaking about a gallon of oil a day the old Detroit keeps on ticking.

i don't know of any vehicle that you can drain the auto transmission without dropping the pan

 

I don't know about Nissan's but Chevy transmissions had drain plugs in the transmission pan. I just put a TH-350 trans in a jimmy and the old and new trans had drain plugs.

 

A 78' Ford with a Detroit is no where near the same as 3rd gen HPCR Cummins. I think I am just gonna start telling people, hey, it's your $12,000 engine if it goes, do what you want! Why would you wnat to use the stuff they make for the HPCR fuel system, heck just dump some ATF through that puppy! Those $600 injectors probably won't mine a bit!

 

All Nissans have drain plugs in the tranny pan. They also do not use a paper filer. They use a metal screen. The things people do these days. Only engines I know of with a sludge problem is the ones the people don't change the oil in like they are supposed to regularly. I have seen my share of sludge buckets. Take the drain plug out and the glob of oil just plops out. Then the laughing begins.

 

I know a guy who did the same to his truck (non-Dodge).

He was the same one that drove around in 4 wheel drive for a couple of days on the pavement because he forgot it was engaged. 75-80mph down the highway for miles and around town.

He's torn up a couple of trucks.

 

That is exactly why folks continue to do it. They know it worked for dad and grandad so they figure it's OK for them too. They don't realize that the fuel system has much higher presures along with much closer tolerances. (this is my guess anyway) Hell,if it was not for boards like this who knows I might be pouring it in mine.

I know people that years ago use to pour atf in the intake of gassers to burn the carbon off the valves.

 

I Run a Can of weed Eater 2 stroke oil in every Tank ! Also In My VW Diesel.

Luke S,

Not meaning to hijack the post, but your gallery shows a nice Mopar performance tranny pan. What's it fit and how much?

Thanks
Pete

 

Pete, I got it right out of our annual Mopar performance catalog. I am going to put it on my 93' D250. The book says it'll fit an A518/46rh. Don't know about anything else? I'd think it'd fit the newer one's also? My dealer cost was around $170 and some change, retail is just over $210 if memorey serves me which it rarely does!

 

I'm not a common rail but I prime my filter housing with whatever I have available at the time. I have used lucas, kerosene, two stroke oil, power service,10-W30 mixed with kero, Red Line, Amsoil, Sheafer, WVO, STP, ATF, all kinds of nasty stuff.

I have even seen guys dump gallon jugs of water into the old Detroit two strokes to clean them out.
