I recently ran Rx and have had zero consumption with S2000. I just changed the oil and sent it off to be sampled to be sure there is no antifreeze in it. I'm now running M1 0w-30 and at 500 miles I am already below the full line. I'm not too surprised, but did not think at 500 miles I'd be seeing this. I think I might run Delvac or 0w-40 next. I'm not about to check my oil every 3 days. I noticed Mobil's website refers to Delvac 1 as the "stay in grade" oil. Nice, but what about the rest.....
If there is one thing I wish Mobil did, it would be to formulate more on the upper end of the 30wt scale. I know they shoot for mpg, but I think consumption issues could be solved if they did this.
I asked Amsoil and Mobil about the thinning and thichening of oils and there responses were similar. Amsoil said that the managers at Oil Analyzers Inc. said going up or down by one weight is permissible. Mobil said all multi visc. oils will tend to do this but you don't want an oil to thin out to much. Does Mobil realize there oils thin out the most?
