Review: Magic Snake Oil for Engines - Used Comma EF400M for one day prior to oil drain and filter change. Filled with X-Flow. Fast idled 10 mins. Drained for one hour. Changed filter again. Filled with appropriate EcoLife synthetic oil from Comma. Initial impression...the change is unbelievable. The engine is significantly quieter. The fuel consumption has improved by at least 10%. Won over. Gobsmacked. Hoping the improvement in engine performance lasts. Quite frankly I am struggling to believe the difference and I am driving looking at the consumption talking to myself asking wtf is going on. The previous oil was also manufacture recommended synthetic. The car .. 2010 Jag XF 3.0D with just 40K miles. What made the miraculous change... The 1st flush, the second X-Flow flush or the EcoLife oil? Or all three? I tried the two flush process as a result of reading others comments here... What can I say? Thanks for the advice. I will follow this approach for all future oil changes. It's worth the time and money.
Review: 'Does exactly what it says on the tin. ' - I have used many engine flushes where you add it to the the engine oil but not this type. With this engine flush, you drain the old oil first and then top it back up with the cleaning addictive and run for 10mins @ idle and then drain and replace with fresh engine oil, sump plug with washer and engine oil filter. X-Flow Flush Out is extremely effective at cleaning the internals of the engine where the engine oil flows. There was an immediate effect after the service with the flush. The car is much more smoother when changing gears. A smoother acceleration and less noticeable/abrupt when changing gears. I've driven the car for almost 500km (approx. 310mi) since the service with X-Flow Flush Out. The engine oil on the dipstick comes out clean like a brand new engine, I've never experienced such a great clean with the flushes that you added to the oil to clear it out. X-Flow Flush Out beats them all in clearing out all the sludge and gunk inside the engine and actually cleans the internals, in my opinion. I would recommend this product to anyone and follow the advice from a professional mechanic & vehicle's manufacturer guidelines as well. P.S.: in the Q&A section, people are asking to pour half capacity or the whole bottle. I used the whole bottle in my 1.8L engine with 5.5L engine oil capacity to flush the engine out. To be honest... I think filling up to the minimum mark on the dipstick should be sufficient enough for a deep clean. And you would save some for the next time after a few services. I wouldn't recommend using this every service. Probably after every 2 or 3 oil changes. UPDATE (MAY 2018): It has been 5 months since I last used the X-Flow Flush Out during my regular servicing. The engine oil has barely darkened in my petrol engine and engine oil use has lessened vs. previously. I would still recommend it to anybody who's looking for a deep clean of their engine.

### ⭐⭐⭐⭐⭐ best i have ever used
*by B***R on 13 March 2020*

I was a bit doutful at first, but after trying it on my big jumbo transit , i wish i had known about this sooner it's the best i have ever used, if you are going to do a proper oil change empty your old oil out, pour in x-flow to just above the min on your dipstick and take a run around the block, remove sump plug and then you will see the crap this stuff cleans from your engine remove old oil filter, fit new filter and sump plug and fill with a good quality oil. I used to get the garage to do mine but no longer.. what a differance not only to the sound of the engine but to the colour of the oil and the fuel saving by way of more miles to the gallon. . But this engine flush is a bit more expensive but you get what you pay for ! whats the point of doing an oil change buying good quality oil and skimping on the flush out , X-fLOW Flush out is the best as i have found out
