The problems referenced above with the 0W-40 were on an OM603, not an OM61x. I use the 5W or15W in my cars, which have OM602, OM603, and M119 engines. Mercedes specifies the 0W-40 as factory fill for fuel economy reasons, not engine longevity. If I owned a 606, I wouldn't use the 0W-40 in that either...

I also wouldn't put it my 616 or 617. Other than being cheap at Walmart, it has no advantage over 5W40 in a old diesel. The M1 5W40 has better diesel ratings and is more than adequate for cold weather starting. The M1 website also recommends 5W40 for the 616/617.

I hope mine quiets down, I had the identical issue, 3 weeks into M1 0W40 and thrashing machine. Darn, I went back to 5W40 Valvoline Premium Blue Extreme--My daughter had difficulty sourcing Val-5W40 so she went with the M1, HUGE MISTAKE--get this though, I put the new 5W40 mobil 1 in my 602.961 without a hiccup. I'm really hoping I'm not putting lifters and an oil pump in this thing next month.

Hey,

I just noticed my local AutoZone has the Truck one too, so I bought some. It's 5w-40 and was $6.19 each--whoa. I'm running the 0w40 now. I guess we'll see how it goes.

Has there been issues with the 0w40?

Some people observed increase wear metals in oil analysis, and increased hydraulic lifter noise, with the 0W-40. Both symptoms went away when the same engine was switched back to 5W-40 or 15W-50. Mercedes uses the 0W-40 for fuel economy reasons, not engine longevity.

I did not see this thread, but when I was at wallymart I saw the 5w-40 and bought two big jugs...
that's why this place is great- you all think like I do- er maybe I think like you do?

I saw it yesterday for $5.99 a quart at the local Autozone. I'll wait for a sale then buy two oil changes worth.

I bought mine in the 4 quart jug for $23.00 something at Wally World. What a place. Has every thing. Then I changed the oil in the 85 and I simply can't believe the difference. It started this morning at about 35 degrees, like it did on the 4th of July. Instantly, with one short glow! And without the block heater. And it runs and idles so quiet. And a totally smooth idle instantly upon starting up. Then the simple fact I can run this stuff twice as long and have all the above benefits, I think someone would have to be nuts not to run it.

Amen, brother. But you'd be amazed how many people resist the switch and come up with all kinds of reasons not to use D-1. I can't say enough good things about it!
