Oil consumption
« on: August 16, 2017, 07:06:05 PM »
2008 Winnebago vectra with 55,000 miles. Is three quarts of oil in 2500 miles acceptable or excessive?

That seems excessive to me.  Something is wrong.  It could be something simple like a leak or it could be something serious.  If it were being burned you'd probably be laying down a smoke screen so my guess would be a leak or excessive blowby forcing it out.

Which engine?

Excessive, if it is actually using the oil. However, in my experience diesels will throw out any excess if the crankcase is overfilled and dip sticks are often not accurate. If it drops 3 qts and then hold steady, probably no worries.

The ISC and ISL engines have a couple different oil pans available and the capacity differs,
