Just switched to RP 5W 30 from ENEOS 0W50
 

Granted the ENEOS was 2000 miles / 3.5 months old but must say, my first experience with Royal Purple is positive, it is smoother at idle and it does feel better in normal driving, temps about 10deg less also normal driving here in ATX, prolly due to it being fresh but I will monitor till the next oil change.

Just thought Id post up, not opening 'another' debate on oil.

Going to use oW 40 at next change, REDLINE I think to continue to see how this Z reacts.

I noticed the smoothness with RP as well, but the thing was i changed from the factory fill and anything was probably going to feel better than what was in their to begin with...

Oil temp wise I got almost not change from the factory fill...

I'll going to try Castrol Edge next and if i don't notice any differences then i'll just stick with that one.

Just got back and I have a 'new' little tick from right hand camshaft area that is new?? its hot out but oil temps about 190. Its smooth but that tick is new...

so you switched from a super thick oil to a super thin one i would expect it run smoother going from 50w down to rp30w(royal purple flows easier than almost all other 30w hence the enrgy conserving II rating)

Yep fully aware of the range, not aware of RP energy conserving flow rating though.
Yes expected it to feel different, was surprised by how much, the ENEOS felt so good initially also.

Pity about the dam tick, if it does not settle, I will dump it and go thicker once more.

Any one else having cam tick on 5W 30 RP? bTW !injector pulse

I've had the tick since day one. Factory fill was horribly ticky, switched to redline synthetic 5w-30 at 2250 miles, the tick got a lot better, but still comes and goes when it pleases.

I hear ya, all good this morning . ;-0 Ill see how she goes, apart fromt his new 'noise' she is running great.

I could be wrong but i thought i read the tick is from the VVL system. And that the reason why you have to use a oil with ester is becuase it sticks on the VVL lubricating it better and removing the tick?

Its possible, but the ENEOS was silent, although granted a 0W50

I can not understand how anyone would be worrying or even thinking about a "tick" in this engine as a problem. I have NEVER in my life heard an engine that didn't tick. Carbeurated engines MIGHT be a different story, although they also tick a little. Fuel injected engines WILL TICK...forever.

I also can't see the point in running a different viscosity oil than what is recommended. I have ran German Castrol 0W-30 since 5000 miles, now have 20,000 and have NEVER had a problem - even with the abuse I subject it to. That's the same story for the previous 3 vehicles...2007 Altima 3.5SE, Corolla CE and 90 Camry DX.

They tick. If there's some obnoxious knock or rattle, then worry and post up. Otherwise, if it doesn't tick, then fuel isn't being supplied to the engine and you THEN have a problem.

The fact that you are comparing those cars to a z blows my mind. I know for a fact that if my salesman told me that these engines tick, I would have purchased another car. It's true everything else about the car is amazing, but most people don't like spending $30,000 on a sports car that sometimes sounds like a diesel engine. Just my :twocents: I have never owned a new car that sounded like this before and I plan to change to 0w-50 to see if that helps with the ticking.

6SP_FTW - lol but seriously thanks for the enlightenment ;-0
UPDATE
5W 30 RP does seem to have settled and it drives very nicely - oil temps about 10deg under usual with 90-100 deg ambiant temps.
Z is on rollers to for a base line stock dyno pull with AFR. (this car has been modified and stock so many times I have lost count, so taking the oppourtunity to get a base while in current guise)
I do plan to go to 0W 40 in a couple thousand miles and can recommend ENEOS 0W50, so 370zFORme - go for it, the motor was very quiet with this in the mix.
