ok so ive been running royal purple in my car for over 40,000 miles. my friends are all telling me that royal purple is terrible for a motor and that i should be running mobil 1.what do u think

 

i have done a cam swap on a motor with royal purple in it and i must say it was a disgusting site to see. that stuff IMO is junk. use OEM mobile 1 or get AMSoil.

 

Royal purple is not very good oil in my book. I tried it one oil change, and within 2 minutes of start up my lifters were ticking like a champ. I dropped the oil after one day of use and went back to Mobile 1 and the tick was gone. Another buddy used it in the rear diff on his Jeep and it started making noises within one day. He dropped the oil and went back to whatever he used before and the noise was gone. Stay away from it.

 

i have never used it, i have customer raining all over changing from royal purple.

lots of oil analysis reports i have seen that the oil starts getting weak and nasty after 1K,, not very good

 

Agreed. The lab reports I've seen on it show the additive package wearing out very quickly.

 

I hear alot of bad stuff and good stuff about royal purple. My friend has been running Royal Purple in his VIII for a while now with no issues. I for one am using Redline with no issues what so ever. And yes, AMSoil I hear is really good. So I would say try AMSoil or Redline.

 

AH damn. alright well since i just got sponsored by amsoil a couple days ago it looks like ill be going that way for now!

 

yea man that stuff sucks

 

yea man

 

I don't have any experience running it in an Evo but I have ran it for the last 20k in my GTI and I have had zero problems. I like it more than most oils. Also I didn't notice any new noises or anything when I switched. Maybe its all in the weights that are used.

 

I have used royal purple for 30k+ miles now...no issues...& my car is considered to be a strong stock turbo car...has always made good power for the minor things that are done to it...& I have not be easy to the car either...

 

my car loves royal purple. it has ran better with royal purple than it did with amsoil or moblie 1. i did use amsoil in my other cars and loved it. amsoil and royal purple for the win in my book

 

I've used RP in my car for 45,000 miles with no issues.

I changed to Amsoil recently cuz my local shop gives me good pricing!
I changed cuz RP price went up.

 

RP was designed for racing engines when it first came out so thats why after 1k miles its a slush. I dont think they changed the receipe when they started to make it in mass production, i remember when it fist came out it was the sh*t, but it depends on the car though. Our cars love Mobile one and Amsoil IMO

 

i think i should run some testing of RP vs MOBILE vs AMSOIL some oil analysis of all 3 oils at an interval of 5 thousand miles to see where we would sit then.
