Good results!

Thanks for sharing.
(not shearing )

And now..?
Keep it in there a little longer?
(as you should... )
The oil is like new.

 

looks good, i run RP and love it.

 

I run Royal Purple and can tell a difference in engine performance. I like it!

 

If my obsessiveness allows me, I'll keep it in for 4K miles this time.

I'd been considering a change to 5W-30 at a later time, but after these results, I'll probably just stick to 10W-30. I'll use my CR-V as a test platform for the RP 5W30.

 

Thanks for doing this VAD. You really need to push this oil out to at least 5K OCI though. Hang in there. You can make it!

 

Thanks for posting, VAD. That's a really good UOA. IMHO, I believe that lots of highway driving is keeping the moisture out of your oil, therefore keeping your TBN high. I realize you don't like keeping your oil in for a long time, but I think you aren't getting much (if any) less wear from short OCIs. You're spending a lot of money on a premium oil and not taking advantage of its ability.

I have a different perspective on engine maintenance than you do. You're using an expensive oil and changing it very frequently to keep it clean. Yet you're using a K&N air filter which is letting harmful, abrasive dust into your intake for slightly better engine performance. INDYMAC knew you were using a K&N because of the high silicon levels.

For the most part, the silicon is essentially tiny particles of quartz. They're very hard and abrasive. If you browse through the UOA forum at BITOG, you will find that high silicon levels are usually associated with high wear metals. Your wear metals aren't high primarily because you didn't have that many engine starts (when most of the wear takes place) and you don't have that many miles on the oil. If you were to switch to a stock air filter and increase your OCIs to 5000 miles, you will likely see no increase in wear metals with your driving habits.

But even if you don't change a thing, your engine will likely last a very long time.

 

i run RP on my first 2 change oil and it drunk atleast 1 qtz of it in a 3000 miles interval change...

so i decided to change back to mobil 1 ... much cheaper and most people are happier about it...

i have read so many reviews about royal purple and reviews are not so great on our cars... i guess on other car is ok but no on ours...

 

ive ran RP for two years and my car hardly uses any oil. it does burn oil, like all s2ks do, but nothing out of the ordinary. this is the 5th UOA ive seen from a RP s2k and they all look great.

 

All S2K's do NOT burn oil.
