Penrite Engine Flush

Excellent – Very happy with the results, I have been using Penrite's engine flush for the last 5 years and have noticed each time I do an oil change my new oil stays cleaner a lot longer than it did before using it. I feel that when my car is due an oil change the oil still looks good, never black. I usually do changes at approx. 10k intervals One vehicle I purchased last year had a slightly noisy lifter, after dosing it, letting idle for 10 to 15 min, draining the oil, changing the filter plus new quality oil, no more tapping. I normally service around a dozen cars a year, to buy it by the bottle per car is costly so I purchased a 20 ltr drum on special, now makes it a lot cheaper. There is no reward for me doing this review other than I'm very impressed with the results. I hope this helps others to decide one way or the other. I myself always look at reviews and ask around before purchasing most things. Cheers

Snake oil! – tried it after i read reviews, as i thought a waste of money no change what so ever! thank's to the ppl who write bogus reviews

Penrite engine oil flush is a good product – I bought a bottle of Penrite engine oil flush some time ago and have only used it this week in my Pajero NT diesel. No adverse effects have occurred and the new oil is still clean after the first few days. I am satisfied that the product has cleaned the old engine oil out well before new oil was added. I will continue to use this product prior to dropping old oil from the engine.

It seemed to help! – I’m pretty sceptical about these “add on” products to be honest. I have a 2008 FG Falcon XR6 Turbo that has only done 37,000 kilometres. I have run it on Penrite Racing 10W40 since new & oil is changed every 6 months due to extremely low use, so oil is quite clean anyway. I bought the oil flush on a whim, not expecting anything. I used it as per the label and was surprised at the colour of the oil that was discharged. It was certainly “dirtier” & darker rhan usual. I hope this is good, and I assume it is if it’s releasing sludge, etc so I’ll keep using it.
