thanks for the links. the only oil that i saw being reviewed here after track use is the Motul 300v, a racing oil.

i read a post about a mobil 1 oil having sheared out of spec.

would be interesting to see track day UOA's on non-racing oils.

The remaining is used to occasionally bring the oil level to the top of the dipstick between changes. Never approaches the bottom mark. So, yeah, I use some oil too. I change the oil when the Maintenance Minder indicates it's dropped below 10% oil life remaining. Whenever I get around to it at that point. This is typically in the 6500 - 7000 mile range. Engine oil analysis indicates the oil is still fine when I change it but oil is cheap in the grand scheme of automotive things.

For what it's worth, I have a MY00 and have been using Mobil1 for years. As far as I can tell, my engine doesn't burn a noticeable amount of oil.

I'm not going to read through all this banter. In the OP case id run the cheapest non syn 10/40w you can find. I would normally not make that recommendation ( always full Syn) but in this case at the rate the engine is burning through it, this will be the cheapest option and should slow the rate of consumption down some. The engine is tired and on its last legs it sounds like, so it doesn't make a lot of sense anymore to invest in expensive full syn oil. That would be more prudent to prevent the current issue, not post this issue.

Full syn has better lubrication making parts last longer. Its cleaner, and it retains its lubrication at higher temps then conventional oil does. It also retains its effective lubrication through longer change intervals. All that said, its well worth the added cost of an oil change. There is no argument for conventional oil, unless in the OP case where there is excessive usage and some blow by, then just keeping oil in the car is what matters. Do it as cheap as you can, the wear/damage is already done.
