Mobil1 0W-40 (SN version) actually held up well for me on a 5k run. But then again, I did need to add a 1.5 quarts make-up oil (burned through 1 quart on a 1,200 mile trip) so that probably helpd the uoa. I switched to M1 10W-30 High Mileage for one oci and consumption was down to about 1 quart in 5k miles. Mola told me that 10W-40 would be even less volatile than 10W-30 because of the more stable base.
Do you think VM's these days are more stable than ones from a few years ago? I change my mind on a daily basis about what oil to use. Currently using Motul 300V 0W-40 since I got it for free with Subaru bucks. I love uber moly oils. So smooth and quicker engine/turbo response (according to the butt dyno)!
Hmm, would 2 qts of RD30 + 3 quarts of ATM equal a Red Line street type oil?
