I don't need you to tell me how to post Jeff.

 

wow, you guys change oil a lot . it definitely won't hurt anything but is a bit much. if your running mobile 1 you can very safely go 5,000 miles, then change the filter and top off with 1 quart, and go another 5,000 miles. a lot of the german cars go over 10,000 miles without even a filter change. the sythetic oil just doesn't break down at all. as long as you keep if filtered it's fine.

 

You sure had alot of time to play footsies with VegasG35sedan earlier. Point being if you spent the same time researching your point, the flame war would have never happened. But alas history repeats itself yet again

Just get the Amsoil ASL SAE 5W-30 and the new EaO12 oil filter and youre set for a year/25,000

SERVICE LIFE
AMSOIL Synthetic 5W-30 Motor Oil is recommended for extended drain intervals in unmodified(1), mechanically sound(2) gasoline fueled vehicles as follows:

• Normal Service(3) – Up to 25,000 miles or one year, whichever comes first.

• Replace AMSOIL oil filter at 12,500 miles or six months, whichever comes first (other brands at standard OEM* intervals).
• Severe Service(4) – Up to 15,000 miles or one year, whichever comes first.

• Replace AMSOIL oil filter at 15,000 miles or six months, whichever comes first (other brands at standard OEM* intervals).
• In all other applications, extend the oil change interval according to oil analysis or follow the OEM* drain interval.

 

I'd recommend against going w/ the ASL... check out the specs:

Kinematic Viscosity @ 100°C, cSt (ASTM D-445) 10.6

Kinematic Viscosity @ 40°C, cSt (ASTM D-445) 57.3

Viscosity Index (ASTM D-2270) 178

CCS Viscosity @ -30°C, cP (ASTM D-2602) 5254

Pour Point °C (°F) (ASTM D-97) -51 (-60)

Flash Point °C (°F) (ASTM D-92) 228 (442)

Four Ball Wear Test (ASTM D-4172B: 40 kgf, 75°C, 1200 rpm, 1 hr), Scar, mm 0.35

Noack Volatility, % weight loss (g/100g) (ASTM D-5800) 6.6

High Temperature/High Shear Viscosity
(ASTM D 4683 @ 150°C, 1.0 X 106 s.-1), cP 3.2

Total Base Number 12.2

------------------------

If you look at a viscosity chart, you'll see that a 30weight oil goes from 9.30-12.49 @ 100 deg cel.

and a 20weight goes from 5.60-9.29 @ 100 deg cel...

according to this info the newly reformulated ASL is no good for the vq.. it's almost a 20 weight oil!!...

I'd go with something on the thicker side such as the HDD s3k:
