Is an engine flush a good idea? In the past I would have had to say no…DON’T do it. But things change and todays cars use oil for more than just lubrication. Variable valve timing and other engine controls are now using engine oil pressure to operate. For that to work they must remain clean. They are protected by very fine screens that can and do stop up with sludge. This has made me have to rethink the engine flush. The products we tried in the past broke up sludge in chunks stopping up oil pump pick up screens. This was my hesitation to relook into the flush systems. Enter our BG products salesman who assured me that his is different. The BG system dissolves sludge into very fine particles that get trapped in the oil filter where they belong.
It will typically continue working on into the next oil change, so you really should shorten the next interval up to about 1000 miles. You start out with a new oil filter and drain the engine oil. The flush is then added in the amount recommended by the manufacturer to fill the crankcase. The engine is then run for 1 hour and the oil is then changed with normal oil and another new filter. Be sure to check out our video on YouTube https://youtu.be/VIN4-JTjxwY on the subject to see some dramatic results.
This is an important thing to consider as the miles add up on your car. The fine screens on Valve Timing solenoids and Phasors block very easy. An engine flush every 50-60K miles is not a bad idea. Remember your care is a valuable asset to your family. It is very expensive to repair or replace so a little maintenance along the way is always a sound investment.
