Oil Choices

I think I'll go for a different brand next time and see what happens.

good first move. i would also check your PCV valve, if it rattles when you take it out, it's OK. if not, it's about 5 bucks to replace. a faulty PCV will not vent the crankcase right and will force oil past your piston rings and burn up. that's a real thin oil too, not too hard to force that past crevices and into the combustion chamber.

so you've always used 5W20 and gone the same intervals before changing? if it's all the sudden like this, i doubt your engine is just giving up the ghost. something is causing it to consume oil or lose it somewhere.

don't be too alarmed either. some cars use a fair amount of oil in between changes. it's the consistency of use that's the factor.
