Used and will test the cleanliness of the engine after a few more trips. Flushed engine twice so hoping for great results

Unbelievable. Used the engine oil flush on the weekend. Drained the old oil & put fresh oil in using the old oil filter. Added flushing concentrate and ran the engine for 30 minutes before draining the oil again. I couldn't believe how dirty the new oil came out after 30 minutes. Put in new oil & filter and ran the engine. Had difficulty see the oil on the dip stick the oil was so clean.I've used the decarboniser, engine oil flush, fuel enhancer & anti wear. I would highly recomend all of them.If you have any questions on any of the products cost effective sell, speak to Jimmy. He is very helpful.

First time I have used this product. Tried it on the mower first. Had to use Start You Bastard to get it going for years. One flush with the oil flush and it has compression again and starts easy with no SYB. Just done the diesel 4x4 and amazed at the colour of the oil that came out. One thing now I can’t see the oil on the dipstick it’s that clear.😂 Be interesting how long it stays clear.

Early days, but the flush certainly removed a large quantity of what appeared to be black sludge. From new oil to black in 30 minutes run time at a fast idle idle. Will need to run up some hours on the motor to determine the ongoing effectiveness.

Pk ford ranger, 220,000kms. I used the oil flush and it has really done it's job. My oil was usually black within 100 km's of an oil change. I've done 250 km's since flushing and the oil looks like it's straight out of the bottle. Very happy with the results so far.

First time in years that I have had clean oil after an oil change, normally goes Black straight away does what it says it will do. Great product, and great service from Matt at Cost Effective Maintenance

I’ve used this product many times before on both petrol and Diesel engines. The sludge it removes from my 4.2 D patrol, 3.0 CRD patrol and 4.5 petrol patrol, not to mention my 3.0 V6 petrol navara, is absolutely astounding. No other flush works as good as this does
