Is an Engine Flush Good or Bad?
An engine flush volition oft better engine performance, but you may desire to skip it with old, high-mileage engines.
Permit'due south get right to the signal: Is an engine flush good or bad?
Spend a few minutes perusing online forums and y'all'll notice a range of answers to this question, often involving an onetime Trans-Am,* Camaro* or other auto that someone thrashed on for years, parked in a pasture for a decade and at present wants to revive with an engine affluent.

What is an Engine Flush?
An engine affluent is an aftermarket chemical additive designed to clean accumulated deposits, sludge and other gunk from your engine.
You pour it into your engine's oil-filler port and idle the engine for about 10-15 minutes. It mixes with the oil and circulates through the engine, helping dissolve sludge and make clean deposits.
Then, you drain the oil (along with much of the gunk, in theory), modify the oil filter, add fresh oil and return to the business of driving.
How Deposits and Sludge Grade Within an Engine
If it did its job, your engine's operation will return to the heady days of its youth, when information technology delivered maximum power and efficiency.
Over time, still, harmful deposits and sludge may have accumulated, causing ability and operation loss.
Deposits and sludge can form for several reasons, including…
- Frequent short trips that don't allow the oil to fully warm up and evaporate wet
- Ingestion of clay
- Fuel dilution
- High estrus breaking down the oil
Equally information technology settles, sludge can clog narrow oil passages or the screen on the oil pickup tube, restricting oil menses to vital parts, peculiarly the upper valve railroad train.
Deposits can crusade the rings to stick, reducing engine compression and horsepower.
The tiny openings in the oil pickup tube screen tin can easily plug with sludge, starving the engine of oil.
Tin can Engine Sludge exist Removed?
Yes. The proper detergents in the correct concentration tin dissolve engine sludge, deposits and varnish.
Ideally, sludge won't form at all; however, sometimes mechanical bug arise, such as a leaking head gasket, and the formation of sludge occurs.
If sludge does form, the oil's detergents assist dissolve and disperse sludge to clean the engine.
This is more than challenging than it sounds.
For starters, the oil must perform several functions, not just help prevent engine sludge.
For that reason, oils incorporate a limited concentration of detergents (compared to an engine affluent product) to ensure room in the formulation for other additives that protect confronting clothing, fight oxidation, gainsay rust and more.
An engine flush product, on the other paw, is designed solely to clean.
AMSOIL Engine and Transmission Affluent contains nothing but potent detergents, making it a more effective cleaner than motor oil.
Plus, it cleans at the molecular level, ensuring deposits are dissolved and properly exit the engine with the oil when information technology's tuckered. This is important since some motorists fear that an engine flush volition free large chunks and crusade an barrage of debris to clog passages inside the engine. AMSOIL Engine and Manual Flush guards confronting this scenario.
Is an Engine Flush Necessary?
A good engine flush tin assist loosen deposits and deliquesce sludge, helping return your engine to like-new condition.
Nevertheless, in old engines with high miles, sludge may be the only bulwark keeping oil from seeping through worn or cracked seals.
Removing the sludge exposes the seals for what they really are – junk. Soon, your engine begins leaking oil, and your mind instantly associates the engine flush product with an oil leak.
In reality, the seals were already bad; the flush simply revealed their true condition.
If you lot suspect your vehicle falls into this camp, get out well plenty alone and skip the engine flush.
It'due south probably not worth trying to revive an engine in such poor condition without first fixing the bad seals or other defects.
In effect, you're choosing your problem: either sludge and deposits robbing performance or, if you make clean the engine, the seals showing their truthful condition.
An Engine Flush is Part of a Good Maintenance Regimen
But that's not to say an engine flush is never a expert thought.
In fact, information technology's often the first footstep in helping restore a neglected vehicle to top-notch functioning. And, often when y'all buy a used vehicle, that's what yous're getting – a vehicle whose owner plant antiquing on Sat afternoon more enjoyable than irresolute oil or dropping the transmission pan. Consequently, your "pre-endemic" ride, while not consummate junk, may boast a sketchy maintenance tape.
In these cases, a stiff, detergent-based affluent can aid prepare the engine for new oil, loosening mucilaginous valves or rings and helping remove harmful sludge.
While not a required stride when switching to AMSOIL constructed motor oil, we do recommend flushing your engine if yous want to give your vehicle a fresh starting time.

5 Benefits of an Engine Flush
1. Prepares Your Engine for New Oil
An engine affluent helps loosen viscid valves or rings and remove harmful sludge and other contaminants.

2. Helps Increase Fuel Efficiency
Contaminants circulating throughout the engine can lead to oil breakdown and increased viscosity – and higher-viscosity oil requires more than energy to broadcast throughout the engine.
Sludge and deposits on engine parts can also increment resistance, which wastes fuel to overcome. Cleaning the engine helps ensure parts move efficiently, maximizing fuel economy.
3. Helps Reduce Emissions
If deposits in the piston-band lands cause the piston rings to stick, oil tin drift into the combustion chamber, where it burns.
This not only leads to harmful deposits, information technology too increases frazzle emissions equally the burned oil exits the tailpipe.
A good engine flush helps free stuck rings and reduce oil consumption, in plow reducing emissions.
4. Helps Reduce Oestrus
Excessive heat is bad for your engine and the oil.
Extreme heat reduces engine efficiency while increasing the rate at which the oil oxidizes (chemically breaks downward). Sludge and deposits act equally insulators that forestall the engine from dissipating heat every bit designed.
Flushing your engine helps ensure it manages heat properly for optimum efficiency and oil life.
v. Convenience
This might non employ to every engine flush, but it applies to AMSOIL Engine and Transmission Flush. It delivers results after just one application. And information technology just takes 10-15 minutes to use.
Plus, you can safely use it in gas or diesel fuel engines and automatic transmissions.
While some solvent-based engine flush products require a cumbersome disposal process, AMSOIL Engine and Transmission Flush uses a detergent-based formulation. As such, yous can dispose of it easily with waste oil.

Post-cleanup with AMSOIL Engine and Transmission Flush, the cylinder head is noticeably cleaner.
Engine Flush Products: I utilise AMSOIL Engine and Manual Affluent
For the record, I've used AMSOIL Engine and Transmission Flush on three unlike pre-owned vehicles in my time, and it's worked smashing.
I of them, a 1999 Honda CR-V, accumulated more 220,000 miles before rust forced me to replace it.
Another, an Oldsmobile Intrigue, ran great until a computer trouble forced me to merchandise it off…for the CR-V.
The third ran great, but I sold it off afterward information technology, too, rusted out.
