I’ll try the Nissan ester oil next change ...I guess the main question would be when or what should i look for to be a concern ..if it even is anything

:iagree:
Seafoam cuts down the viscosity of the oil. Makes it watery. Doesn't allow the oil to stick to the rotating parts. Creating dry spots on the bearings.

I got some vids ..but had to actually set the phone in the engine bay to hear it .. I’ll post them soon

This video I was able to get the sound by putting the phone in the engine bay so it sounds louder than it really is

I had this same condition in my 09 Z and is original operating for our VQ37HR engines to be noisy. I was paranoid for some time for nothing thinking I would have no choice but to rebuild or replace my engine. I started using the 5W30 Nissan Ester motor oil and 5W30 Royal Purple motor oil and in turn it quieted the drivetrain a lot try it. Also I went back to using the Genuine Nissan oil filters and the Genuine Nismo oil filter not sure if it helped quiet it down.

You can use Seafoam in our cars it works well but I highly recommend changing your motor oil and oil filter after you Seafoam though. The only fuel injector cleaner I used that actually worked was the Chevron fuel injector cleaner using the Chevron with Techron gasoline at the same time.

That stuff is flat out junk and does nothing. You always give bad advice, ALWAYS...

Know your facts before you go spouting off at the keyboard. You’re opinion is biased to Shell gasoline (French oil) and you only care about boosting your post cost. Chevron/Texaco gasoline is top tier gasoline and Techron is a great additive for keeping vital internal engine parts clean. I have stripped down two Nissan 2.5L and 3.5L engines that used nothing but Chevron gasoline,Chevron fuel injector cleaner, and Chevron fuel system cleaner the whole life of them. Both the 2.5L and 3.5L had 300K+ miles the combustion camber, intake valves, and cylinder heads were quite clean and had no caked on carbon deposits as what a lot of fuels that I seen leave on an engine after 300K+ miles says a lot about Chevron fuel injector and Chevron fuel system cleaner it has been proven to work time and time again.

I've used white vinegar and a handful of coffee grinds to clean my fuel injectors and never had a problem...

I plan on switching oil ... was thinking royal purple .. redline ... or Nissan ester oil not sure which would be best

I'd go with Redline. Worked wonders with my chatter. Anything OEM is price gouging, and as for Royal Purple - your engine oil should never be the color of alien blood.

Agree... I've used Seafoam (both in oil and mixed with fuel) in most of my engines for years (2 stroke, 4 stroke,...) and have seen the difference it makes. I can't say the same about other additives.

Yeah, that works great too when you're running low on funds. :tiphat:
