Decided to change oil in my dad's MB E350 since it hit 1000 miles and I like to change the factory filled oil right after it hits the magical 1000 mile mark.
Filled it with 8 quarts Royal Purple 5w40 and a K&N HP-7004 fleece filter(rebranded Mann filter made in Germany)
Dad didn't know I changed the oil since he had to fly out for a reunion. He came back yesterday and called me to ask me if I did anything to the car. I told him that I just changed the oil in his car just to get the factory fill out.
First he gave me a riot act for changing out the factory fill because he is very frugal and stingy and even though I bought the oil and filter and I don't charge him for anything but oh well.
Secondly, he mentioned that the car ran much quieter and smoother now than before the change, hence him calling me to find out so he can continue doing whatever I had done to his car. His exact words to me were that it felt like he was driving on "glass"
Now my dad is not a car "guy" For example, his last car had pinging issues and he was completely oblivious to it. When I asked him why he had not mentioned the pinging to me, he looked at me awkwardly and asked "What is pinging?". So, for him to notice this with just a change in motor oil, I tend to lean towards not being just a placebo effect plus he didn't even know I did an oil change.
I decided to do some googling about Royal Purple motor oil experiences and discussions and to my overwhelming surprise, I found a lot of people on other car forums having the same reactions as my dads. They also noticed that the car ran quieter and smoother after the royal purple oil change than ever before. Maybe there is some truth to this rather than just a placebo effect? What say you guys?
BTW, even though I took my dad's car for a spin after the oil change, I can't say if it ran smoother or better because I have not driven his car extensively to form an opinion about it.
