What oil are you using?

I have been running our DD's with full synthetic on a 7,000 mile change interval.

Used Mobil 1 since I bought it new. Overkill on my part as it gets changed twice a year, every year and currently the car is at 30,000 miles after 12 years. It's not required to change that often just something I do to make myself happy.

Sent that Amsoil request in on the 28th, haven't heard a thing. So I guess ordering isn't the route I'm going to take. I'll buy the high zinc Amsoil from Napa and switch one car over to it with a flat tappet cam and run it for a while and do an oil annalys and see how it fairs.

I believe that the oil change monitor goes strictly off of mileage (regardless of oil's actual condition). At least... that's how it is on my Honda.

I never use those things, they have no idea of the quality of oil poored into the engine, they are just based off driving habits and mileage.

The best way to know when it's due is to do an oil annalys. It's not expensive and once you do one or maybe 2 annalys' on a particular car, you'll know when to change oil, then the annalys is no longer needed for that vehicle as long as you stick with the same oil/filter combo you tested with. Your done with testing at that point unless something changes. You might find that it doesn't jive with your oil light one way or the other.

Yeah the only way those "Oil monitoring system's" would work accurately is if they actually had a on-board oil analysis system, which they don't. Otherwise it is just based off of mileage, driving conditions, and driving habits like FBJ already said. Those lights were invented for dumbasses who didn't or couldn't figure out when their oil needed to be changed. I actually hate those lights, I have one on my Daytona and it is annoying as hell to reset it.

DOMINATOR 10W-40 has been really good for the track.
