MANNOL: reviews and customer ratings

Mannol Extreme 5w40
Excellent oil at a decent price. Been using this in my old GS Suzuki for a couple of years and no downsides. I was pleased to find it also has a JASO MA2 rating, but I'd have bought this anyway, as I've been using car oils in my bikes for decades. I decided to go for the 5w rating for quick lubing in the cold.

I’ve been using MANNOL oil for several services now, and it’s been consistently excellent. Engine runs smoother, quieter, and stays clean even after long intervals. It offers incredible value for the price compared to other premium brands. Highly recommended!

Mannol is best quality

After just a few tanks with diesel there is a significant change in behaviour, all positive. Less noise, a little more responsiveness, and wouldnt you know, a noticeable reduce in consumption. Compared to other additives I think this is just as good as the better ones, better than the average ones. I've tried lots of these additives since about 1995.
At the moment I mainly drive a PSA with the infameuos 2,0/163 Euro5.
If this reduce consumption at a level as other good additives, this is a win for the wallet. The good ones will normally reduce consumption about 5%-ish, depending on what engine. Whats maybe more interesting is that these kind of additives, who raise the cetane, reduce smoke hugely. In a car with DPF like mine it means that the DPF will not be clogged even with mainly short rides.
Unfortunately it comes in bottles not really designed for filling into the tank, so it has to be filled into long-neck bottles. Not a big deal, many additives comes in plain bottles.
Bigger cans like 5 litres would be brilliant.

I am very surprised and pleased how this oil performs in my PSA with the 2.0/163 Euro5 engine. Biggest difference compared to well known and high priced brand oils is the ability to clean the engine. The 2 first oil change with this gave me black oil when draining. Now it seems the engine and oil keeps kind of clean even after 4 months, thats not the normal for a diesel. Consumption of oil was low before, now it is nothing. So it seems it cleaned up and loosened the oil rings at pistons? Anyway, very happy with the performance. Price tag is extremely low compared to the quality oil I used before.

The Mannol Energy Combi LL is the winner in the price-performance evaluation. It's the best oil in viscosity that works well especially in the cold. The additives were also successful. The only annoying thing is that the label is not clear, although it has a VW approval. i was looking for my passat b5.5 1.9 tdi 130cv specific oil and i found this article from independent identity that mesures all type of oils. this one is the best for the value. do your research like i did on google and you will find the article of this label

I’ve been using Mannol oil previously on my air cooled v twin bike and now use it on my e85 Z4. Absolutely no issues but I did change my oil and filters every 3k on the bike and every 5k with the car. I know it would have lasted a lot longer but it’s cheap enough to be able to do that and in doing so maintain maximum viscosity. I just live to look after my engines.

Very poor quality. It crystallizes far too much compared to other products I’ve tried. I suspect that using it for 40,000 kilometers damaged the entire AdBlue system of my Peugeot 308. When I disassembled the AdBlue tank, everything inside was crystallized. The injection nozzle and the exhaust system were also in very bad condition.

Probably the best I have came across. Really nice light amber colour and ideal viscosity. You can almost feel like the happiness from the car after oil and filter change.
on Volvo S60 2.0Turbo Petrol 2006 engine B5204T (for this engine it is required 5.8liters so get an extra liter)
Highly recommended!

Do not buy! I have never really had issues with cold start, but this is the first time I heard that engine was not able to lift the oil to the top of the engine. Oil looks like thick sludge at -5 celcius. Definitely doesn’t meet the old RN0700 spec. Engine sounds totaly different with similar spec.

I wasn't sure about using this but after first doing a engine oil flush and filling the engine with the oil the car feels better than ever definitely be using again normally Ester based oils cost more this is a bargain and will be my go-to oil for engine oil changes.

it works great but mannol need to invest in a bottle that does not leak during transport. autodoc packs them in a sealed bag so it does not leak on other products but it means they know it leaks every time during transport....autodoc should complain to mannol
