Did the college thing already, slick. FREE of charge courtesy of the US Military and the State of Texas. That's why I work for a developer. Did the military thing too (obviously)....you should try THAT sometime. Maybe you'd learn some respect. Especially for those that defend your freedoms. Wanna see my tail??? You're not man enough.

 

I just responded to your threatening PM. We can keep the personal bickering private now. I doubt anyone else wants to read it anyway. Thanks.

 

I appreciate both of your information. I guess whatever helps you sleep at night. Just like the fellas that change their oil every two thousand miles, everyone has their ways. The bottom line is, you can’t go wrong using the owner’s manual for reference if you don’t know any better.

 

I agree with Roast on this one. Stick with what the manufacture states, not some goober named motoman who works on bikes. Of course changing it more often can't hurt, it just cost more.

The filings sink to the bottom of the pan and stay there. If they circulated, the filter would catch em.

I can't believe nobody has addressed the main issue here.
You should run 3-10 thousand miles on regular oil because it allows the piston rings and various other moving parts to seal/seat properly. The rings and the walls create a little bit of friction rubbing together, allowing a tight fit to be established- kind of like bedding in brake pads. This is done at lower RPM's at first, like the dealer recommends. After that break in period, you can run synthetic and reap the benifits of low friction operation.
I am pretty sure that failure to abide by these guidelines is what is causing all the "My car burns oil!" posts. I have 50,000 miles on my Z and it doesn't burn more than 1/2 quart per 4,000 miles.

 

I changed my oil at 1200 miles. Then again @ 3K, 6K, 9K, At 12K I figure the motor had been broken in sufficiently by then and went to Mobil 1 Syn. Redline was too expense (That's another story). I change that Syn oil every 5K or sooner as I do in all my cars. As for waste of oil / time - It's the acids that breakdown the oil that you really want to get out of there after you seat the rings and other internal engine parts. Syn doesn't breakdown as fast and it provides less friction. You should reap the benefits of syn oil for better mileage and longevity. Heck, I figure getting over 200K out of my last street motor I must have done something right.

However, if you are gonna race the heck out of the car there are two theories:

1) You'll be rebuilding the motor every few races /years depending on how hard you race anyways, so who cares
2) Use the syn .... I want to get the most HP out my motor by spinning it with the least fiction and give it the best chances not to breakdown that oil so fast under racing conditions. I go this way on road course cars. On drag cars I go with step one and build a loose motor.
