While reading a post on this subject on a different web sight, I thought I'd start one here. Other rvers were getting anywhere between 500 to 2000 miles per quart. On a recent 5,000 mile journey I used less than 1/2 quart. I use Valvoline 10W-30 synthetic in a '90 Chevy 454, now with 32k miles. Is anyone else out there getting such phenominal mileage? My average speed on the open road averaged between 50-55mpg. Maybe this had something to do with it, but it still seems like pretty low usage. Your input?
Have a 94 Chev K3500 crew cab with 454, has 115000 miles on it. Uses less than 1/2 qt for 3000 miles. Last MH had a Ford V10 with 26000 miles on it. Used no oil between changes. I used Mobile One in both vehicles after 6000 mile breakin. New MH has a GM 8.1 engine with 6500 miles on it, just switched to Mobile One. I don't know if the Mobile One has anything to do with the low oil consumption or not since I take the Toad (97 Malibu) to the Chev dealer for service. They use Havoline 5W30. The Toad has over 60000 miles on the odometer and doesn't use any oil. It also gets its oil changed every 3000 miles.

I have a 454 with 22K on it. Uses about 1/2 quart per 3K miles. I think I'm using Pennzoil 10-40W this time.

My mh has cummins and uses no oil between changes. Follow strict changing guidline by manufacturer. Use Delo as recommended. use of synthetic does not change the time period with cummins warrenty, therefore no advantage to using it.
Our 91 Pace got about 3,000 miles to the quart up to the time I sold it with 125,000 miles on it. Used Mobil One ever since break-in. Our 3176 Cat in our current coach gets about the same, but with 7.5 gallons of oil, I use regular oil!

My v-10 uses no oil between changes, but it only has 14,000 miles on it.

My current 8.3 Cummins uses about 1 to 2 quarts per 6000 miles. I add no oil between 15,000 mile changes and it is right at 1 gallon low at the change. BUT, it didn't start out that way. It seemed to use twice that while breaking in. Happy Motoring, Butch - Mission, TX. - for awhle..
