Post your oil analysis and lets compare and analyze!

I decided to go with Blackstone labs, which can be found here: http://www.blackstone-labs.com/

Conventional dealer Valvoline oil with OEM Nissan oil filter after Nissan recommended 3,800 miles sent for analysis:

Results:

I'm still pondering if the silicon is that high, wouldn't that typically mean it was dirty oil, and if that is the case, then wouldn't I be wanting to change it earlier than 3800 miles? My OEM engine air filters are clean and were changed I think in my previous oil change.

I would be very interested in other interpretations of these results from iS gurus!
 
I'm not a fan of Valvoline, I run castrol gtx with a quart of lucas in everything I own. I just sold my tundra with 240k on it and when I changed a valve cover gasket it looked new no gunk at all.
 
I did put lucas in 2-3 times since I've owned the car, but I can't remember if it was during this last oil change.
 
Just bringing this thread back up. Had my oil tested at the end of last year with 4650 miles on it and here are the results with using M1 5w30 with Lucas Oil Synthetic Oil Stabilizer.
After the change I used M1 Extended Performance 5w30 and again used the Lucas Stabilizer, I will update when I send out my sample again.

Thanks for sharing your results guys. I ordered the free test kit and will try it when I run Amsoil in my FX. Jonas, you did switch over to syn since that last change, right?

yep. I'm at about 5,200 miles. I'm thinking of sending it for analysis at 6,000 to see if I can go longer to 7,000 or even more then change it at that time that they recommend.

Yeah! Post it! :)
 
I know the paper says it but high levels of silicon = dirt getting past the filters. Are you filters dirty a little? I'd check them first and check for any leaks. Maybe something throttle body related too? Those on Nissan engines are notorious for getting dirty extremely fast.
 
I'll check tomorrow morning. I think I'm due for new air filters at 60,000 miles. I'm heading to the dealer tomorrow morning for an oil change too.

Well if silicon = dirt and I'm at 6,500 on full synthetic, then isn't that telling us that our FXs should not be going for that long intervals especially if everything is alright which I think it is because the FX is running like a champ?

I was thinking maybe the silicon was from the rubber tube used to pull the oil out of the dipstick? The oil pan, dipstick, etc is very hot and putting a rubber tube down it to suck out oil I'm wondering if that is impacting the results.
 
Jonas, one thing I noticed is that you went from Valvoline to Penn Ultra on this oil change. The ultra has detergents in it to help clean up the engine. So possibly the Ultra is cleaning out the old stuff out of the engine. I would worry more if the next oil change has high amounts also. Hopefully you filled the new oil with Penn Ultra to get a consistant analysis.

High silicon is almost always a direct cause of dirty air filters. K&N filters are known to throw a higher silicon level.
 
Thanks! Yep went to the top of the line oil per your recommendation! I forgot that this may be the cause of extra silicon in the results. The ultra penzoil turns engines into self-cleaning engines unlike any other oil so that makes sense!

At the dealer now getting an oil change with ultra again. I'll test at 6k miles next time and we'll see how the results look.

Thanks!
 
Jonas, Personally I would change the air filter more frequently then 60,000 miles. I like to change mine at 24,000 miles or every couple of years.

I changed mine once or twice already...whatever the recommendation is in the manual...it's either around every 20k or 30k miles I can't remember...I just know the next time it's due is 60k miles. Since I've had the car, I've followed all the recommendations to the book as far as air/cabin filters, maintenance items, etc.

I would never wait a full 60k miles for an air filter, especially when it's not expensive and easy to change myself. :)
 
Excellent, my bad, I read it the wrong way, I really didn't think you would leave any maintenance too long.
 
Another thing you may want to look into is that the VK50 motor using VVEL (variable valve event and lift) technology. The lifters in that are more prone to wear which leads to noise when you don't use an oil with an ester additive in it like the Nissan Ester oil or Redline motor oil. The VVEL engines are very demanding from what I've seen on G37's that also use VVEL. The ester helps reduce friction more. The high copper could also be coming from your engine internals wearing alot more since your not using the ester oil. It wouldn't hurt to try it once and report back.
 
are the FX35s not VVEL? What exactly is the difference?

Mechanic mentioned about the Ester and how the second you switch back to regular oil the noise comes back. 99% of the infinitis at all the dealerships don't user ester because of costs and dealerships don't recommend it either unless the car has a lot of that engine noise where the customer really wants to get rid of it but that is rare.
 
FX35's don't use VVEL only the FX50, M56, QX56 and G37.

Here's something via wiki:

Nissan VVEL:
A rocker arm and two types of links open the intake-valves by transferring the rotational movement of a drive shaft with an eccentric cam to the output cam. The movement of the output cam is varied by rotating the control shaft with a DC stepper motor and changing the fulcrums of the links. This makes the continuous adjustment of the amount of the valve's lift (e.g., the amount of intake opening), during the intake valve event in the four-stroke cycle, possible. C-VTC and VVEL together control the valve phases and its valve events, allowing free-control of the valve timing and lift. This results in more efficient airflow to the cylinder, significantly improved responsiveness, optimizing the balance between power and environmental performance.

My dealership I go to also agreed they only use it when the engine sounds noisy (ticks, clicks, lifter noise, etc) and to reduce wear and tear on engine internals with VVEL.
