I was very satisfied after using Max-Clean fuel additive in my Mercedes-Benz S500 V8 550.
Today I have put Royal Purple HPS 5W30 oil in its engine.

With this oil change there is instant difference in engine performance right after initial start. Motor is much smoother and quiet.
I have discovered the motor oil, that I will use exclusively for all my cars.

Last 4 years I have been using only Royal Purple 5w40. A very good and high quality motor oil.
Excellent engine performance through the years and now with MaxClean for the fuel.

Diagnostics found that injector 3 of my car is not working right.
After the very first use of Royal Purple Max-Clean and a 1000 km trip the parameters of this injector turned normal and the engine is running smoothly.

I will definitely order this more in future! Such a great oil, keeps my oil pressure high and can handle very well high rpm levels. Stays stable even under hard pressure.

I was a bit sceptical, about this oil, but when I changed my old with this one, the engine works much better. I will calculate the fuel consumption and tell if there is any difference.

This is a company vehicle, with a daily drive of over 100 km in Sofia. After I switched to Royal Purple HPS 5W30 the engine is quieter and the car accelerates faster. This oil makes a big difference.

After 1 year and 18 000 kilometers with Royal Purple oil I chose again their products.
HPS oil is the perfect choice for engine protection, fuel economy and is at affordable price.

Now, after 1500 km I can share that the engine is “calmer” and works more quietly
(as far as this is possible for this vehicle to be quiet :) )

I had an opportunity to see Royal Purple performing on the test machine and was very impressed with the quality of the oil.
For my vehicle I chose API 5W40, which is perfect for my engine and the climate in our area.
I noticed difference with the new oil right after the first start. Engine now works easier and is quieter than before.
K. D., Opel Astra DTI 16V

Right after I started the engine with the new oil, I felt that the car starts so easy. Next day I had to travel from Sofia to the sea side (Bourgas). The car is way more responsive before boost and overall the typical diesel engine knocking is gone. If I am giving a ride to somebody not knowing that the engine is a diesel he will never guess it. I instantly felt a decrease in the fuel consumption of 0.4l to 0.9l per 100 km. I am thinking it may even go in savings of 1 liter.
I am very satisfied and from now on will be a lifetime user of Royal Purple HPS.

Subaru is a very specific type of car. Mine has been manufactured in USA for the US market. I always use high quality products when maintaining it.
That's why I chose Royal Purple Max ATF.

For my last oil change I used royal purple oil. Now the engine is not that noisy as it was before and the driving is a pleasant experience.
I would recommend Royal Purple to everybody.
