If you have been facing issues with oil circulation in your car’s engine recently, you’ve probably been thinking about rebuilding the engine. Over time, the by-products of combustion and dirt accumulate in the engine, so rebuilding is a great way to get rid of them. However, it takes a tremendous amount of time and may be very costly.

|Liqui Moly Pro-Line
Fortunately, an engine flush may be the answer to your problems. At a fraction of the price of rebuilding an engine, flushes can effectively remove sludge and restore oil circulation. It should be noted, though, that an engine flush may be unable to deal with tough engine pollution, leaving you no choice other than to rebuild the engine.
1. Liqui Moly 2037 Pro-Line Engine Flush
If you are looking for an engine flush that will be compatible with vehicles equipped with catalytic converters, then Liqui Moly Pro-Line Engine Flush might be the right pick for you. Aside from that plus, this engine flush is formulated to work with both gasoline and diesel engines.
This engine flush is neutral to seals and other relatively delicate aspects of the engine. However, you need to perform an engine flush properly within the time specified by the manufacturer.

2. Throttle Muscle TM7326 – Best Engine Flush for Large Engines
Throttle Muscle TM7326 is a more sophisticated engine flush since it can be used in engines after a prolonged no-drain interval. Aside from that, this engine flush is formulated to be used with engines that have an unknown service history, which could be useful if you own or are planning to buy a used car.
Throttle Muscle Engine Flush comes in a large 128 oz. canister, which allows you to use it for multiple engine flushes. However, such a large amount could also be very useful in extra-large engines.
Throttle Muscle is a bit pricey, although you do get 128 oz. of the flush. In case you can’t afford to spend about 30 bucks on an engine flush, you could go for the smaller 16 oz. flush or choose one of the other engine remedies we examined.

The most notable one is that Lubegard’s solution is formulated to flush the engine in a matter of 5 to 10 minutes.

If your car has a turbocharged engine, then you might want to consider the Motor Medic MF3 Motor Flush. It has been specifically designed for gas, diesel, turbo, as well as naturally aspirated engines.
To be fair, you could probably use the other engine flushes we reviewed for turbo engines. However, remember that they weren’t designed specifically for turbocharged engines, meaning that you could run into issues with your engine. To be safe, you might want to just go with this engine flush.
