What is really crazy that it is noticeably better engine oil. It's always suggestive to say it's better ... but suggestive or not my engine is running noticeably better and quieter. And then I prefer better quality like Castrol for a few Euro more.
Very fine oil.What more should I say about it.Something else is that I had ordered two lights together with this oil.They were not immediately available.That turned out after inquiring on my part.2 lights of together less than 3 euros.After a lot of mail and patience almost 2 weeks after ordering the lights are also in the house.Looked a bit like my first and last order at mister-car ......
Quality engine oil.
The best motor oil on the market I have used castrol for the last 55 years and there is none better.
Great value, great service, Fast and reliable prompt reply to order, thank you
Excellent oil with a spec that exceeds all you need. Long lasting and does what it says Sticks
on the vw the engine sounds and performs better. On the down side 4 litre jacks are a pain .Make 5 litre jacks.
