Better than advertised,brilliant.
Just like the Mannol diesel (fuel) additive,the product is brilliant.Added to sump oil in a 1.6 hdi Peugeot engine of around 87000 vintage,the immediate difference was impressive,engine was smooth before but even quieter with the Mannol additive.Rgarding ratio I just introduced it with a 3.5 litre oil change,(total fluid including filter) and 1600 miles later the oil is noticeably clearer than before,ie not blackening within the first 100 miles post-change.Before the oil change I used Mannol engine flush as it's the only one you can safely drive for around 50 miles while it's in circulation,and that certainly left the engine interior very clean prior to renewing sump oil.Possibly due to using these Mannol products,I'm not certain,but in the 5 years I've had my car ,mostly urban runs,traffic etc with little motorway use,it's averaged 40mpg at best,38mpg mostly,and that was on premium/regular diesel mixed,but since feeding it's systems with the Mannol diet that mileage has shot up to a sustained 50+ mpg,and that's with heavy trailer use,town runs etc,absolutely brilliant stuff,I would recommend Mannol to anyone,especially at the Amazon prices and delivery etc.

Use it when your old engine really worn
when your engine happened white smoking,this will help ,but if not,don't use this as it is very thick oil additive may doing harm to oil passage and piston ring when your car still very good condition.That is for highly worn piton ring.

Lack of gas
Bought 2 and both add low pressure for the spray and one of the even finish the gas with a lot on the can . These things should be loaded with ozone gas cause it last more and you can fill more product with it

Ik heb een oudere auto met heel wat kilometers op de teller. Door slijtage was er frictie tussen verschillende motoronderdelen. Ik deed een blikje Mannol in het oliereservoir terwijl de motor nog warm was en sindsdien voel en hoor ik het verschil. Door de hogere viscositeit verbruikt de wagen nu ook beduidend minder olie.
