They should use Mobile 1 full synthetic.
While yes, at 10k miles, synthetic is still better than new dyno oil...in a 400 HP environment it would be a good thing to do what the CPU tells you!

While the oil may not break down on the extended mileage stuff it still will have funny things floting around in it. Thats not for my "V".

Clean cubes are happy cubes!!! :yup: Change the oil and filter every 3 to 4 thousand miles. Stick your finger in it and smell that old oil next time you change it and you will know it needs changing! :eek:

The LS2 in my GTO saw over 15 trackdays this past year. Oil life monitor expired at 9K the first time and 10K the second time. Too long for my taste. The oil life computer was reset only when it expires but change Mobil 1 every 5K miles. 75w Royal Purple in the diff. every 10K. The oil monitor does not display like the V.

Max, does your rear whine with the purple?

And I always thought 10k was a little long for oil, but 5k to me is just right.

Although I will say Mercedes and Audi all say 10k for their oil service and BMW says 15k.

No reason to change your oil until GMOLS tells you to, period. I have proof.

i put 5000 miles a year on a car and normally change once a year. No problems but what do you all think with the V.?? I've always had lower performance engines however.

Ben, I agree with you for a stock engine, I would like to see the "proof" just for curiosity sake
As I had mentioned on this topic before... after 8k then next 10k miles my GMOLS was @ 0% for at least a week, did an oil change (after the 8k then after 10k) on my CTS-V and as usual sent in a sample for analysis, result oil was good enough to be put back in for another few thousand miles.

Oil has measurable properties, when it breaks down or becomes dirty time to change it, until then no reason to pour your $ down the drain on any car regardless of cost of the car.

Kadonny, it did a little after about 300 miles. After the whine in the V I was pretty sensitive to the noise most would never hear. Switched to the second heavist RP gear oil and was almost completely silent. There is just a hint of whine at 21K miles that passengers cannot hear unless I point it out to them under the right conditions. I answered "it is just a characteristic of the car" when pass. ask about the noise from the diff.

I think the heavier weight dampens the slack or chatter from the gears. It might effect MPG but it is not noticeably. What is neat is it has it's own friction modifier included. :)

what is 'GMOLS'?
General Motors Oil Life System. Google it, it's a pretty slick system. About the only thing it dosen't know is time and dust or other oil contaminants as it does not have any sensors that monitor the oil.

the GMOLS is fine and dandy...Ill spend my 50 bux every 3K miles and be done with it. There is no better peace of mind for me, and thats what counts.

Check the older service manuals of the Europeans and compare it to the current intervals of 10K, you'd see it was less.

Here's why:
They do your oil changes for free!!! If Cadillac ever included oil-changes in a free-maintenance schedule, they'd raise the limit too to save some cash.

There's no reason to be stingy with oil and wait 10K or 15K on oil changes, heck, your intake pulls enough oil-vapor from the crankcase to warrant an added quart every 2-3K miles! 5K is fine with today's synthetics, IMHO.

I only run Royal Purple in my machines, change every 5k in cars...2K in bikes. Its good insurance for the motor, keeps the crap out of the engine, and gives me time away from the wife....I think I may do a change tomorrow!
