Royal Purple. Engine Damage In The Long Term?

Waiz · 01-31-2011, 06:57 PM

7-8K, really?

I was running RP for awhile and once went all the way to 6K and it turned to sludge.

I now just run M1 to about 5K and have had no problems, I as a general rule would never run to your intervals OP.

if you want to run longer in between oil changes I would suggest getting a synthetic filter. I switched to the RP filter and am giving that a try. I will cut it open at 5k and see what it looks like and make my determination from there with the oil evaluation. if it seems good I may try running it longer. I also use a larger filter, I can look up the number if you would like. In conjuction with the RP I always use Zmax as well. This all may be overkill especially with my 34 row oil cooler but it gives me a piece of mind. If I find that the RP is not doing what I like I will switch to something like redline or amsol.

how do you use a RP filter that they don't make for NIssan 370Z?

I commute 36 to college and the same back every m/w/f. It's my daily driver too, so yeah. I put alot of mileage on it. My last oil change was the start of this month and I already have 1.5K on it.

Thanks for the info though, I'm gonna switch to M1. What do you guys recommend changing it at? 5-6 maybe? and what kinda filter is best with M1?

I use M1 with a k&n filter. I'm sure there better filters out there but I'm happy with it.

I usually change every 5k.

What year, make, and model was that, that slugged?
7,500 is the limit for Synthetic oil, the OP is fine!
