I've personally never had an issue with Royal Purple fluid so long as it was changed at the respected intervals

 

I've always used Mobil 1 per my oil cap, the high mileage stuff, even when it was brand new. Someone told me the high mileage stuff has higher zinc concentration and better detergents in it.

 

Mobil 1 EP (extended performance) supposedly is the best mobil has to offer as far as additives go. Don't use it longer than 5k miles though, the 15k mile change is BS.


Semi Synthetic oils are like fake synthetics, it will feel like a normal synthetic until 3k miles, then turn to garbage. The full synthetic I am okay with using for 4.5k miles.


Europe has the best car oil market in my opinion. You can get many oils in Europe that you can't get here in the states, especially motul products, and motul makes good stuff generally.


I think royal purple would be just decent, not anything special in my opinion. If I lived in Europe I would be all over the euro brand stuff.

 

I do it every 3,000 so I'm all good on the waiting too long thing. The worst I've ever let it get once was 4500 before a change.

 

Dude I live in the states and I use a German oil called liqui Molly 10w60 full synthetic, It's what bmw m3 have to use, look it up, my machine is built and that oil seems very good.

 

Wait, are you actually suggesting this guy use 10w60 in his stock evo engine?

 

I was recommending the oil brand, they have many weights available.

 

Next oil change has became and this time I use Royal Purple HPS 10-40 for summer use instead of cheap Motul. First feel the car start work a little quiet without vibration but idle still swimming often.
I recommended this oil to my other evo owners and they changed their oil to RP oil too for every day use. For track use they still keep 300v 15-50 at the moment big promo in Ukraine for 2l bottle about 28usd.

 

 

Do an oil report on Royal Purple before you give everyone an ok this oil is great message. I've done multiple oil reports on a certain oil and got better results than universal averages for the evo. Let an oil report do the talking, not an engine idle vibration feel...

 

I don't have any data to back anything up but I run rp xpr 20/50. I road race the car so my oil changes are more frequent than most, sometimes I change the oil after 1k miles. But it works just like any other oil as far as I can tell.

 

Mobil 4T Racing oil

 

Due to high amount of fake oil on the market most famous european oil brands such as Motul,Elf,Total and etc I would like to choose american oil which original produce . Next oil change I will try amsoil signature. In Russia it was tested in the lab with very high specification and good feedbacks.

 

I bounce between Castrol, Amsoil, and Mobil1. Never had an issue with any of them and they always look fine at the 5K mark.

 

Interesting in Mobil and Castrol too but hard to find original oil in Ukraine.
Will buy directly amsoil from US.
