I have been using Mobil 1 5w-30 in all my cars for 4 years and never had any issues.
After reading about alot of burning issues on this and other forms, I had doubts about putting it in my new used 03 touring with 30,000 miles of dino oil already run through it.
I just changed it today after 2500(changed a little earlier than I normally would because of it being the first time synthetic was used) and the oil level had not moved. Never had to add a drop.

i just put royal purple 5 quarts of 10w-30 in it with a mobil 1 oil filter. how often do i need to check to see if it is burning oil ?

The dipstick is not the best... I think some people check the dipstick and think they're down 2 quarts of oil, but in reality they just aren't reading it correctly.
The only real way to know how much oil is in the engine is to do an oil change, and measure what comes out of the motor.

Ran Mobil 1 in my Cobra and now for the last 10k miles in the Z. No oil consumption in either and actually dropped the operating temp in the Cobra just as much as the Amsoil I tried.
Wow. You have to be the first person in existence to not think the dipstick on the VQ35 is a P.I.T.A.
I've even tried taking it out and letting the oil in the tube drain back down before reinserting and it still comes out all streaky.

just to fill all u guys in, mobile1 just down graded their oil to a level III. they no longer use a PAO oil, which sucks. its no longer any better than a normal crap oil. it is weird b/c exxon/mobile still break records with profit and they still cut corners.
Amsoil, RP, Redline, Motul FTW!

I found that thread too and it's the reason I hate going to bitog for information. It's one thing that I am in no way a chemical engineer and have difficulty deciphering all the acronyms, but even they are all in disagreement about every topic. There doesn't seem to be any consensus re: which oils are better and they spend most of the time discussing formulation when all I really care about as a car enthusiast is performance.
Isn't there a simple set of tests a third party can perform on oil to determine things like lubricity, breakdown/sludge resistance, etc.? I'm going to have to write to Consumer Reports...

zenophile, the way I understand it...
synthetics are much more resistant to viscous breakdown than dino oil. that said, it seems that some 350z owners are having problems with synthetics blowing by a little too easily.
for good lubricity that you can measure using a typical oil analysis, look for molybdenum, which represents MoS2, a good high temperature lubricant.
I've seen the virgin oil analysis for motul 300v, and it's got a rediculously high moly content, which should equate to very good lubricity. Given that it's a synthetic, it should resist breakdown. As for blow-by, I have no idea.
Given the rediculous price of things like 300v, I just stick with dino oil. My motor seems to run great with it. If you change it at appropriate intervals then you will be fine.
