Catalytic converters and oil

Mt Tam I am · 07-15-2010, 11:38 AM

Originally I only thought to check my oil at 500 miles because of high oil temps (245* during break in under 4000 revs). I was down 3/4 qt. down another 1/2 at 1000 miles, now 2 1/2 qts at 1800.

Nissan is having me drive another 1500 miles to see if I have an actual problem. With all that additional hydrocarbon going through my catalytic converters, will they be compromised?

That's actually a good question I don't think I've seen asked.

I'd imagine it would have some type of impact, I'm unsure what though.

Possibly, but keep in mind your catalytic converters are covered under warranty for 80,000 miles.

I'm going to go with what everyone else is saying. I'm sure if its burning alot of oil it would cause premature failure of the cats. If Nissan replaces the engine or something from the oil consumption, have them replace the cats while they are at it.
