S.T.P  works for me "the racers edge"

Thanks,STP is famous. Is it ok in the winter too,or switch back plain oil before winter?

how cold is your winter?...

I only knew about their injector additive... but what you need for bad oil consumption is thicker oil...
Casite C162 Motor Honey - Premium Oil Treatment ... used car salesmen used it to pass on bad engines... is that what Lucas additive is supposed to do?...
It's not greatest idea,.. because it thickens oil to reduce consumption, but that must also reduce the oil's ability to flow through smaller passages in the engine...
30wt won't be good for that weather either...

If the car is worth keeping,... I'd go ahead and get valve seals if that's all it needs.

PS,... but check your PCV valve...  that could do it.

I tried to change the PCV valve ,but it is on the valve cover close to the firewall. Hard to reach and can't see it . It came out of the grommet but the PCV valve won't come out of the hose.It's a really stiff hose that  dissapears into the motor somewhere . I almost busted some stuff leaning on the motor . I don't know how a mechanic will do it ,but I'm going to have to go to one. Oh well.

Let me ask, i noticed the guy who changed my oil last might have used a shorter oil filter, but same diameter  than the one the book calls for ,a couple of inches. Could this cause the oil to be consumed somehow? If it's the wrong oil filter? Thanks.

The purpose of the pcv valve is to prevent backfire (true backfires thru the carb) from blowing out your oil pan.  A sticking pcv will usually prevent the blow by from being sucked into the air cleaner.

I don't remember all of the tricks, but if excessive blow by is causing you to fail... route it somewhere else for the test.

new plugs, pcv and distributer cap is what I remember how to get it to pass.  Maybe new plug wires too.
