Is it true adding transmission fluid to the oil will help my 88 cadillac run better?

Answer 1

If your friends jumped off a cliff would you?

Where did you hear that? If it was meant for transmission fluid to be in the oil, then they would build cars with the engine and transmission compartments connected...so the fluid could disperse between the two.

Answer 2

I own a shop, and have heard this same thing. What they are talking about is; Transmission fluid is a very high detergent oil, and by adding some (such as a half of a quart) to the engine oil will clean sticking lifters, and make an engine run better. Rather than doing this, I would suggest (if you are going to do this anyway) purchase some stuff called "Risilone" from the parts store, and follow the instructions on the bottle. This is some very good stuff, and I have used it on many occasions with good results. Transmission fluid will do the same thing, and may even be cheaper, but somehow I wouldn't feel good about using it in the engine. One must be careful as to what they put into the engine now days, and especially pay attention to the fact it may not do too well with your sensors. If you use anything, make sure it is something made for the job, or you could do more harm than good.
Part 2:
It's funny everyone on here has been voted bad answers, how can that be? Someone must know what they are talking about, or else they wouldn't waste their time answering these questions. Transmission fluid WILL NOT harm your engine, but running this fluid "only" might. I haven't seen one single engine damaged by using a high detergent lubricant in small quanitites. I have a vehicle with 250,000 miles on it, and it still runs good, so somewhere along the line I must have done something right. I change the oil every 3,000 miles, and if it startes making any valve noise, I will put something in it (probably Risilone) to free up the lifters & rings. Both of them will stick some when they get a lot of miles on them. If I were you, I would stick with people who are real mechanics, and use products on the market that are designed to do the job. Take advise from people who know, and have experience, not from some guy who used to work for some dealer in town. We all know dealers are out to make all the money they can, and will tell you that you need everything done to your vehicle, when it only needs the oil changed. No one gave me my certification, and I have to pass a test each year to maintain my certification, so people who work on their wifes car in the back yard on week-ends, doesn't hardly meet the criteria to be a real mechanic. You asked a question, and got some good honest answers, so no one cares if you vote for someone who is the brother of a cousin who used to work at a dealership years ago, but it would make sense to take advice from experienced people who take time to answer questions to help you. For the people who "claim" transmission fluid harms engines, what web page is the proof on? That's right; there is none.
Glad to help out, Good Luck!!!

Answer 3

No.

Apparently the engine is not running well, or you may not have asked the question.

No matter what you add to the oil, the engine will not run better, but if you can make a few repairs, such as installing a clean air filter and fresh spark plugs, it probably will improve.

If you must add something, then add two cans of fuel injector cleaner to a full tank of gas and do not add more fuel until most of the mixed fuel/cleaner is used up. If you have not done something like this on a regular basis, or paid to have it done by a shop. then the engine will likely perk up noticeably before the tank is fully used.

Answer 4

not the greatest idea, but, if you have problems like, valves sticking, or excessive muck built up internally, you could drive the vehicle for the standard 3000 miles, and fill the engine back up to full with AFT (it will be a little low) start it up and let it run for about 10 - 15 minutes, then do the oil change.
now be careful, i work in a lube shop, and i have seen some one grab the wrong gun and fill an engine with AFT. left in too long , you can run into some issues.

Answer 5

helloooo... if you are using a heavier viscosity oil than what the factory recommends, transmission fluid will change the viscosity to a lighter state and the engine will use less power to turn itself. this is why you feel it runs better. it has more power to use elsewhere. but no, its not good for the engine mixed with xmission fluid. it will cause carbon build up and harden seals and who knows what.

Answer 6

no it is not peolpe do that right before they change there oil to clean the motor do not run ATF in your engine it was made to run on motor oil not trany fluid
