Well, my EVO hit 18K miles and I just did an oil change.....
put in 5 qts. of 10w30 Royal purple, a new OEM filter, a SARD magnetic drain plug and washer.

Once complete I started up the car and noticed the motor idling much more smoother and quieter.....

 

switching this week to it. good to here

 

royal purple is nice...just burns up fast. make sure you check your dipstick every oil change

 

and why would you put a oil like that in your evo..

 

isn't 5qts to 2 much?

 

yea that might be a bit too much. I always put in 4.5 qts or abouts. an extra .5qt will probably just burn away.

 

I thought 5 qts was standard.....

**off to check manual**

I check my oil every week or so....

 

Blue Evo is right...5 quarts is right. oil cooler all your lines and oil pan, it might be like 4.9 or so. so call it 5

 

hehehe Just got back, manual says 4.8 qts....

I just dumped in 5 and called it a day...

 

Yup good info manual tells all

 

and why not? Gets good reviews...i'm not currently using it. I am using mobil for now. Next oil change is Amsoil 0w-30. WHo knows might go back to Royal after amsoil.

 

I usually do a little less than 5qts. I put the oil under the full line of the dip stick.

 

RP 10W 40 works for me

 

Just stay away from r.p. tranny fluid.

 

i used to RP for 2 oil changes (around 5000 miles) and i noticed alot more lifter noise than usual. i realize they are loud to begin with, but they seemed quieter with the mobile1 and after i switched back to the mobile1 the noise was not nearly as loud. im not knocking RP they do make very high quality oils, but ive heard alot of up's and down's about RP. to each his own
