Oil change factoid
So I needed an oil change ( had 5K on the oil) anyway I've been using Mobil 1 for years, this time Walmart was out of 5-30 and all they had was Castrol Edge Titanium..Castrol USA - CASTROL EDGE WITH TITANIUM I figure WTF can't hurt anything, well lo and behold the valve train chatter I had on startup is gone.. no real hard data on why, but I think I'll just stick with the Castrol.. just though some of you might be interested. On and I'm not knocking Mobile 1, just thought this was interesting.

Mobil 1 has many hardcore fans that like to think its the best available. I used to be one of them. Until I learned that different oils perform differently in different engines. It's not the best in our VHR motors. Several others have shown better results over time but many still trust their Mobil 1. It's certainly not the worst, but its not special. If you really want to know how well the Castrol is working, send in a sample of your used oil for analysis at your next oil change. That's where fact is separated from fiction.

I don't know how to post the UOAs but here's my "summary" on PP done at 6k OCI.
BRAD: It's a very nice first report for your G37. Universal averages show typical wear levels for this type of
engine after about 4,900 miles on the oil. You ran a bit longer than that, but the engine didn't mind. A couple
wear metals are higher than averages, but an extra two or three parts per million aren't anything to worry
about. The Pennzoil 5W/20 got the job done. No fuel or coolant showed up and the oil and air filters kept
silicon and insolubles at a minimum. At this rate, your engine should be around for a long time to come.

Sry Matt, the other 2 were done on my 07 G35

There you go with the witty turn of phrase. Good job. A+.

I recently switched to Mobil 1 synthetic and also got more valve train noise. I've got one more oil change worth of mobile 1 in the garage and I'll be switching to Penzoil Platinum after that. It's a shame because Costco only carries Mobil 1 and I used to stock up on it when they had a rebate for a great price. In my previous car (Toyota Tundra 5.7L), I also noticed the Mobil 1 made the valvetrain louder as well.

Personally I have been running a 7500 mile OCI using Penzoil Ultra with good results. I ran one OCI with over 9k and it was still good. I think it's posted in the UOA thread. Platinum and Ultra are not the same but probably will have pretty similar results. YMMV.
I may shorten it drastically once my turbo is installed. I'm not sure how much yet, still researching that.
