I'd never use 5w30 unless the HTHS was more than 3.5-3.6 ! Sent from my Verizon Wireless BlackBerry

Some of the reasons I use the thinner oil: 1) The 5w40 will start quicker, and build oil pressure quicker, especially in cold weather 2) It remains just as thick at operating temp and above 3) M1 Turbo Diesel Truck is only widely available in this weight, and it's intended for diesels and rated to handle more diesel soot than regular M1 4) It's usually about the same price 5) It's MB approved for all temps (is 10w40 approved at all in the current specs?) 6) And last but not least- it's what Marshall used I wouldn't hesitate to use another weight of M1 if I couldn't get 5w40, but 5w30 would be my second choice. I think that the thicker oil will accelerate engine wear, especially in cold climates and offer no advantages in warm climates, except for possibly reduced oil consumption in a worn or leaky engine. My 190DT doesn't burn or leak significant amounts of oil... Tyler Curt Raymond wrote: > What advantage do you see in the 5w40?
