Is there anything to unclog oil? Options

[MeMoe]

I'm just wondering if there is any additive you can add that can clean the oil and unclog pipes.

I read in one of the threads that the celicas from 96 had a problem with oil clogging - any more info on that?

Thanks =)

once i heard some time ago, of people using diesel instead of oil to clean oil circuit in car.
Dont ask if it works or not, i dont have the slightest idea and wouldn't try it myself

I heard that running some kerosene through your engine will clean it up as well, or maybe some acetone (heard that too)....dont know cause Ive never really wanted to attempt this, but maybe one day when I have a spare engine and some fire extinguishers laying around I will....just for fun.

be careful of using acetone or diesel fuel to clean out your engine. In concept it works but you run a high chance of doing more damage then good.

Diesel+ kerosene + acetone all can break down oil. They are great degreasers; however they will break down oil in a molecular level removing its lubrication properties. Its similar to pouring dish soap into your engine.

If you poor in a quart of ATF it will help clean your engine without running the risk of breaking down the oil. ATF has a viscosity of 5w. So when your flushing your engine its best not to run the engine for a long time or under a load.

As a mechanic I strongly discourage flushing engines. Synthetic oils have all the detergents needed to keep an engine clean. Why run the risk of thinning down your oil and causing extra wear. Changing your oil every 3k miles when its hot is the best engine flush you can do.
