This would probably be better off in the Internal Engine forum

I use to use the Mobil-1 5-30 when I first got my Z brand new, (I believe that's what GM recommened for the car) as my nitrous addiciton got worse

I switched to 10-40, and right now for the winter I am using the 0-40 U are asking about!

I can tell U the oil consumption problem most people complained about were apparent to me when I was using the 5-30 in the early days, about a quart every 1500 miles for me, but since switching to the 10-40 for the summer, and 0-40 for the winter oil consumption is non-exsistent for me, and this is on a bone stock, 48,000 mile motor, with over 150 chasis dyno pulls, and 500+ 1320' passes, all with the original from the factory PCV valve still in place.
