That's a tough call. 0W40 pours better than 15W50 at pretty much any temperature. I can only speculate as to what the effects of one versus the other is. Thick might be better when warm, thin better when cold - maybe. Marshall was pro the 5W40 as I recall, but only you know what works good in your vehicle. I switched to 15W50 in my 94S350 as the turbo was going bad and started spewing oil into the intake. Problem went away for a while with the thicker oil. It kept getting worse until I replaced the turbo cartridge. Then I went back to 5W40 again. Chances are your turbo is failing and the oil you use won't make any difference. I'd start looking for a reasonably priced replacement before you need it bad and have to pay up because you are in a hurry. Or wait it out till spring and hope Global Warming works better next year :-)
