Where's it being lost- out the back or out the bottom?

Half a quart of BP 20/50 after two days on the track.

My car's usually good for 1/2 quart for the weekend.

Hey, Mark are you coming to Putnam?

TR6

None that I can detect. And I check it frequently when tracking it.

Yeah, I'm not in the 0 to 0.3 qt category. So I must be getting a bit of valve guide wear. Meh, my car is exempt from emissions here in IL so who cares...

mhm993

.25 quart each day.
68K miles, stock engine, probably 10k track miles.

Same here in NJ....just think of it as an automatic oil change!

Any leakdown test recently?

Eric,

Do a leakdown test to confirm that its not rings or valves. Pull a lower valve cover to do the "wiggle test " and check guide wear.

Although you are emissions exempt, oil consumption leaves heavy carbon on piston crowns and combustion chamber surfaces. These create hot spots that trigger detonation and pre-ignition which are a BIG problem for anything with forced-induction.
