Engine flush? glorified diesel fuel.?

Question

Are the commercial engine flushes little more than diesel/kerosene mix?

Answer 1

About three years ago I wanted to flush the engine in my car. So I went and bought a bottle of flusher. $12.50 for 125 mL!!

Whan I unscrewed the lid to tip it into the engine, I noticed a familiar smell. Just like diesel...

Whilst I was tipping it into the engine, I noticed it was exactly the same colour and viscosity as diesel...

When I read the active ingredients on the back of the bottle, it just said 'Hydrocarbons = 100%'...

That was the most expensive diesel I've ever bought...

These days I just put 50 mL of diesel for every litre of oil in the engine when I flush it. Which is every 15,000 km. I change the oil and filter every 3000 km, but when I flush it, I drain the old oil, put on a new filter and fill with the flush mixture, start and run the engine AT IDLE for 1 minute, then drain the flush mix and refill with fresh oil and a new filter.

I don't waste good expensive synthetic oil when I flush, I just use cheap mineral oil. Still the correct grade and weight, just cheap, because it's only going to be run at idle for 1 minute and then thrown away.

I don't know too much about COMMERCIAL flush.  But I've been flushing my engine with Diesel.  It works really well too.  You have to see the black gunk that comes out with diesel flush.  And the oil stays clean for much longer (800 miles vs. 5 miles).

Good luck...
